Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)
A localized bulging or dilatation in the muscle wall of a heart (MYOCARDIUM), usually in the LEFT VENTRICLE. Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.
Aortic Aneurysm, Thoracic
Aneurysm caused by a tear in the TUNICA INTIMA of a blood vessel leading to interstitial HEMORRHAGE, and splitting (dissecting) of the vessel wall, often involving the AORTA. Dissection between the intima and media causes luminal occlusion. Dissection at the media, or between the media and the outer adventitia causes aneurismal dilation.
A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.
Blood Vessel Prosthesis Implantation
Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.
Blood Vessel Prosthesis
Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.
Tomography, X-Ray Computed
Angiography, Digital Subtraction
A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues.
Anterior Cerebral Artery
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Carotid Artery, Internal
Platinum. A heavy, soft, whitish metal, resembling tin, atomic number 78, atomic weight 195.09, symbol Pt. (From Dorland, 28th ed) It is used in manufacturing equipment for laboratory and industrial use. It occurs as a black powder (platinum black) and as a spongy substance (spongy platinum) and may have been known in Pliny's time as "alutiae".
Carotid Artery Diseases
Reconstruction or repair of a blood vessel, which includes the widening of a pathological narrowing of an artery or vein by the removal of atheromatous plaque material and/or the endothelial lining as well, or by dilatation (BALLOON ANGIOPLASTY) to compress an ATHEROMA. Except for ENDARTERECTOMY, usually these procedures are performed via catheterization as minimally invasive ENDOVASCULAR PROCEDURES.
The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.
The therapy of the same disease in a patient, with the same agent or procedure repeated after initial treatment, or with an additional or alternate measure or follow-up. It does not include therapy which requires more than one administration of a therapeutic agent or regimen. Retreatment is often used with reference to a different modality when the original one was inadequate, harmful, or unsuccessful.
Posterior Cerebral Artery
Mesenteric Artery, Superior
A large vessel supplying the whole length of the small intestine except the superior part of the duodenum. It also supplies the cecum and the ascending part of the colon and about half the transverse part of the colon. It arises from the anterior surface of the aorta below the celiac artery at the level of the first lumbar vertebra.
An autosomal dominant disorder of CONNECTIVE TISSUE with abnormal features in the heart, the eye, and the skeleton. Cardiovascular manifestations include MITRAL VALVE PROLAPSE, dilation of the AORTA, and aortic dissection. Other features include lens displacement (ectopia lentis), disproportioned long limbs and enlarged DURA MATER (dural ectasia). Marfan syndrome is associated with mutations in the gene encoding fibrillin, a major element of extracellular microfibrils of connective tissue.
Circle of Willis
A polygonal anastomosis at the base of the brain formed by the internal carotid (CAROTID ARTERY, INTERNAL), proximal parts of the anterior, middle, and posterior cerebral arteries (ANTERIOR CEREBRAL ARTERY; MIDDLE CEREBRAL ARTERY; POSTERIOR CEREBRAL ARTERY), the anterior communicating artery and the posterior communicating arteries.
Microsurgical revascularization to improve intracranial circulation. It usually involves joining the extracranial circulation to the intracranial circulation but may include extracranial revascularization (e.g., subclavian-vertebral artery bypass, subclavian-external carotid artery bypass). It is performed by joining two arteries (direct anastomosis or use of graft) or by free autologous transplantation of highly vascularized tissue to the surface of the brain.
Mucocutaneous Lymph Node Syndrome
An acute, febrile, mucocutaneous condition accompanied by swelling of cervical lymph nodes in infants and young children. The principal symptoms are fever, congestion of the ocular conjunctivae, reddening of the lips and oral cavity, protuberance of tongue papillae, and edema or erythema of the extremities.
Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization.
Vertebral Artery Dissection
Splitting of the vessel wall in the VERTEBRAL ARTERY. Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the vertebral artery, aneurysm formation, or THROMBOEMBOLISM. Vertebral artery dissection is often associated with TRAUMA and injuries to the head-neck region but can occur spontaneously.
Carotid Artery, Internal, Dissection
Unanticipated information discovered in the course of testing or medical care. Used in discussions of information that may have social or psychological consequences, such as when it is learned that a child's biological father is someone other than the putative father, or that a person tested for one disease or disorder has, or is at risk for, something else.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
Mesenteric Artery, Inferior
The artery supplying nearly all the left half of the transverse colon, the whole of the descending colon, the sigmoid colon, and the greater part of the rectum. It is smaller than the superior mesenteric artery (MESENTERIC ARTERY, SUPERIOR) and arises from the aorta above its bifurcation into the common iliac arteries.
Glasgow Outcome Scale
Coated Materials, Biocompatible
Homopolymer of tetrafluoroethylene.

Synonyms: Fluoroflex; Fluoroplast; Ftoroplast; Halon; Polyfene; PTFE; Tetron.
Tomography, Spiral Computed
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
Intracranial Arteriovenous Malformations
Congenital vascular anomalies in the brain characterized by direct communication between an artery and a vein without passing through the CAPILLARIES. The locations and size of the shunts determine the symptoms including HEADACHES; SEIZURES; STROKE; INTRACRANIAL HEMORRHAGES; mass effect; and vascular steal effect.
Equipment Failure Analysis
Severe or complete loss of motor function in the lower extremities and lower portions of the trunk. This condition is most often associated with SPINAL CORD DISEASES, although BRAIN DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; NEUROMUSCULAR DISEASES; and MUSCULAR DISEASES may also cause bilateral leg weakness.
Carotid Artery, Common
The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.
An autosomal dominant aneurysm with multisystem abnormalities caused by increased TGF-BETA signaling due to mutations in type I or II of TGF-BETA RECEPTOR. Additional craniofacial features include CLEFT PALATE; CRANIOSYNOSTOSIS; HYPERTELORISM; or bifid uvula. Phenotypes closely resemble MARFAN SYNDROME; Marfanoid craniosynostosis syndrome (Shprintzen-Goldberg syndrome); and EHLERS-DANLOS SYNDROME.
Magnetic Resonance Imaging
Spinal Cord Ischemia
Reduced blood flow to the spinal cord which is supplied by the anterior spinal artery and the paired posterior spinal arteries. This condition may be associated with ARTERIOSCLEROSIS, trauma, emboli, diseases of the aorta, and other disorders. Prolonged ischemia may lead to INFARCTION of spinal cord tissue.
Arterial Occlusive Diseases
Rare chronic inflammatory disease involving the small blood vessels. It is of unknown etiology and characterized by mucocutaneous ulceration in the mouth and genital region and uveitis with hypopyon. The neuro-ocular form may cause blindness and death. SYNOVITIS; THROMBOPHLEBITIS; gastrointestinal ulcerations; RETINAL VASCULITIS; and OPTIC ATROPHY may occur as well.
Disease Models, Animal
Cranial Nerve Diseases
Prostheses and Implants
Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
Predictive Value of Tests
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
Oculomotor Nerve Diseases
Diseases of the oculomotor nerve or nucleus that result in weakness or paralysis of the superior rectus, inferior rectus, medial rectus, inferior oblique, or levator palpebrae muscles, or impaired parasympathetic innervation to the pupil. With a complete oculomotor palsy, the eyelid will be paralyzed, the eye will be in an abducted and inferior position, and the pupil will be markedly dilated. Commonly associated conditions include neoplasms, CRANIOCEREBRAL TRAUMA, ischemia (especially in association with DIABETES MELLITUS), and aneurysmal compression. (From Adams et al., Principles of Neurology, 6th ed, p270)
Matrix Metalloproteinase 9
Ultrasonography, Doppler, Duplex
Severity of Illness Index
Constriction of arteries in the SKULL due to sudden, sharp, and often persistent smooth muscle contraction in blood vessels. Intracranial vasospasm results in reduced vessel lumen caliber, restricted blood flow to the brain, and BRAIN ISCHEMIA that may lead to hypoxic-ischemic brain injury (HYPOXIA-ISCHEMIA, BRAIN).
Image Processing, Computer-Assisted
Sensitivity and Specificity
Radiographic Image Interpretation, Computer-Assisted
Surgical Procedures, Minimally Invasive
An abnormal anatomical passage between the INTESTINE, and another segment of the intestine or other organs. External intestinal fistula is connected to the SKIN (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as STOMACH (gastrocolic fistula), the BILIARY TRACT (cholecystoduodenal fistula), or the URINARY BLADDER of the URINARY TRACT (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (MEDICAL ERRORS).
Middle Cerebral Artery
Matrix Metalloproteinase 2
Localized or diffuse reduction in blood flow through the vertebrobasilar arterial system, which supplies the BRAIN STEM; CEREBELLUM; OCCIPITAL LOBE; medial TEMPORAL LOBE; and THALAMUS. Characteristic clinical features include SYNCOPE; lightheadedness; visual disturbances; and VERTIGO. BRAIN STEM INFARCTIONS or other BRAIN INFARCTION may be associated.
A distribution in which a variable is distributed like the sum of the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another.
Care given during the period prior to undergoing surgery when psychological and physical preparations are made according to the special needs of the individual patient. This period spans the time between admission to the hospital to the time the surgery begins. (From Dictionary of Health Services Management, 2d ed)
Databases as Topic
Intracranial Embolism and Thrombosis
A nonparametric method of compiling LIFE TABLES or survival tables. It combines calculated probabilities of survival and estimates to allow for observations occurring beyond a measurement threshold, which are assumed to occur randomly. Time intervals are defined as ending each time an event occurs and are therefore unequal. (From Last, A Dictionary of Epidemiology, 1995)
A chronic inflammatory process that affects the AORTA and its primary branches, such as the brachiocephalic artery (BRACHIOCEPHALIC TRUNK) and CAROTID ARTERIES. It results in progressive arterial stenosis, occlusion, and aneurysm formation. The pulse in the arm is hard to detect. Patients with aortitis syndrome often exhibit retinopathy.
The part of brain that lies behind the BRAIN STEM in the posterior base of skull (CRANIAL FOSSA, POSTERIOR). It is also known as the "little brain" with convolutions similar to those of CEREBRAL CORTEX, inner white matter, and deep cerebellar nuclei. Its function is to coordinate voluntary movements, maintain balance, and learn motor skills.
Hematoma, Subdural, Acute
A class of statistical procedures for estimating the survival function (function of time, starting with a population 100% well at a given time and providing the percentage of the population still well at later times). The survival analysis is then used for making inferences about the effects of treatments, prognostic factors, exposures, and other covariates on the function.
Equipment and Supplies
Reproducibility of Results
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
A slowly progressive condition of unknown etiology, characterized by deposition of fibrous tissue in the retroperitoneal space compressing the ureters, great vessels, bile duct, and other structures. When associated with abdominal aortic aneurysm, it may be called chronic periaortitis or inflammatory perianeurysmal fibrosis.
An idiopathic, segmental, nonatheromatous disease of the musculature of arterial walls, leading to STENOSIS of small and medium-sized arteries. There is true proliferation of SMOOTH MUSCLE CELLS and fibrous tissue. Fibromuscular dysplasia lesions are smooth stenosis and occur most often in the renal and carotid arteries. They may also occur in other peripheral arteries of the extremity.
The internal resistance of a material to moving some parts of it parallel to a fixed plane, in contrast to stretching (TENSILE STRENGTH) or compression (COMPRESSIVE STRENGTH). Ionic crystals are brittle because, when subjected to shear, ions of the same charge are brought next to each other, which causes repulsion.
Basal Ganglia Cerebrovascular Disease
A pathological condition caused by impaired blood flow in the basal regions of cerebral hemispheres (BASAL GANGLIA), such as INFARCTION; HEMORRHAGE; or ISCHEMIA in vessels of this brain region including the lateral lenticulostriate arteries. Primary clinical manifestations include involuntary movements (DYSKINESIAS) and muscle weakness (HEMIPARESIS).
The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).
Statistical models which describe the relationship between a qualitative dependent variable (that is, one which can take only certain discrete values, such as the presence or absence of a disease) and an independent variable. A common application is in epidemiology for estimating an individual's risk (probability of a disease) as a function of a given risk factor.
Prevalence of true vein graft aneurysms: implications for aneurysm pathogenesis. (1/984)BACKGROUND: Circumstantial evidence suggests that arterial aneurysms have a different cause than atherosclerosis and may form part of a generalized dilating diathesis. The aim of this study was to compare the rates of spontaneous aneurysm formation in vein grafts performed either for popliteal aneurysms or for occlusive disease. The hypothesis was that if arterial aneurysms form a part of a systemic process, then the rates of vein graft aneurysms should be higher for patients with popliteal aneurysms than for patients with lower limb ischemia caused by atherosclerosis. METHODS: Infrainguinal vein grafting procedures performed from 1990 to 1995 were entered into a prospective audit and graft surveillance program. Aneurysmal change was defined as a focal increase in the graft diameter of 1.5 cm or greater, excluding false aneurysms and dilatations after graft angioplasty. RESULTS: During the study period, 221 grafting procedures were performed in 200 patients with occlusive disease and 24 grafting procedures were performed in 21 patients with popliteal aneurysms. Graft surveillance revealed spontaneous aneurysm formation in 10 of the 24 bypass grafts (42%) for popliteal aneurysms but in only 4 of the 221 grafting procedures (2%) that were performed for chronic lower limb ischemia. CONCLUSION: This study provides further evidence that aneurysmal disease is a systemic process, and this finding has clinical implications for the treatment of popliteal aneurysms. (+info)
The diameter of the common femoral artery in healthy human: influence of sex, age, and body size. (2/984)PURPOSE: To determine the relevance of dilatations of the common femoral artery (CFA), knowledge of the normal CFA diameter is essential. The diameter of the CFA in healthy male and female subjects of different ages was investigated. METHODS: The diameter of the CFA was measured in 122 healthy volunteers (59 male, 63 female; 8 to 81 years of age) with echo-tracking B-mode ultrasound scan. The influence of age, sex, height, weight, body surface area (BSA), and systolic blood pressure was analyzed by means of a multiple regression model. RESULTS: The CFA increased steadily in diameter throughout life. From 25 years onwards, the diameter was larger in men than in women. Significant correlations were found between the CFA diameter and weight (r = 0.58 and r = 0.57 in male and female subjects, respectively; P <.0001), height (r = 0.49 and r = 0.54 in male and female subjects, respectively; P <.0001), and BSA (r = 0.60 and r = 0.62 in male and female subjects, respectively; P <.0001). Age and BSA were used to create a model for prediction of the CFA diameter (r = 0.71 and r = 0.77 in male and female subjects, respectively; P <.0001). CONCLUSION: The diameter of the CFA increases with age, initially during growth but also in adults. This is related to age, body size, and sex male subjects have larger arteries than female subjects. It is now possible to predict the normal CFA diameter, and nomograms that may be used in the study of aneurysmal disease are presented. (+info)
Focal aneurysmal dilatation of subchorionic vessels simulating chorioangioma. (3/984)Subchorionic vascular aneurysms of the placenta are rare lesions and may present confusion with chorioangioma or focal mesenchymal dysplasia on sonography. To our knowledge, the findings of placental aneurysms have not been reported in the ultrasound literature. We present a case with detailed sonographic evaluation, including spectral and color Doppler and pathological analysis, that was mistaken for chorioangioma prenatally. Knowledge of this benign entity may allow the sonologist to recommend conservative management in similar cases. (+info)
Vasa vasorum: another cause of the carotid string sign. (4/984)BACKGROUND AND PURPOSE: Our purpose was to describe a variant of the carotid string sign that may be associated with a completely occluded vessel and to consider possible pathophysiological mechanisms for this observation. METHODS: Carotid angiography was performed in three patients with suspected carotid stenosis and in a fourth with carotid dissection. Surgery was performed in one of the patients with carotid stenosis. RESULTS: On all angiograms, instead of a single linear or curvilinear contrast "string," either single or multiple serpiginous channels were seen. In one case, such a channel was seen emanating from below the origin of an occluded internal carotid stump, reconstituting the distal portion of the vessel. Surgery revealed a completely occluded lumen with a small intramural vessel bypassing the obstruction. CONCLUSION: We propose that these channels are either atherosclerotically induced neovessels connecting bridging vasa vasorum or recanalized luminal thrombus. We review the literature associated with this subject. (+info)
Mortality league tables: do they inform or mislead? (5/984)OBJECTIVE: To examine certain methodological issues related to the publication of mortality league tables, with particular reference to severity adjustment and sample size. DESIGN: Retrospective analysis of inpatient hospital records. SETTING: 22 hospitals in North West Thames health region for the fiscal year 1992-3. SUBJECTS: All admissions with a principal diagnosis of aortic aneurysm, carcinoma of the colon, cervical cancer, cholecystectomy, fractured neck of femur, head injury, ischaemic heart disease, and peptic ulcer. MAIN MEASURES: In hospital mortality rates adjusted by disease severity and calculated on the basis of both admissions and episodes. RESULTS: The numbers of deaths from specific conditions were often small and the corresponding confidence intervals wide. Rankings of hospitals by death rate are sensitive to adjustment for severity of disease. There are some differences that cannot be explained using routine data. CONCLUSIONS: Comparison of crude death rates may be misleading. Some adjustment for differences in severity is possible, but current systems are unsatisfactory. Differences in death rates should be studied, but because of the scope for manipulating data, this should be undertaken in a collaborative rather than a confrontational way. Any decision to publish league tables of death rates will be on political rather than scientific grounds. (+info)
Arterial aneurysms in patients infected with human immunodeficiency virus: a distinct clinicopathology entity? (6/984)Arterial aneurysms have only recently been associated with the human immunodeficiency virus (HIV). The clinical and pathological features of 10 HIV-positive patients with arterial aneurysms were retrospectively evaluated. These aneurysms were unusual in that they affected young black patients, occurred in atypical sites, and tended toward multiplicity. Surgery was performed in eight patients. Acute and chronic inflammatory changes were revealed by means of histologic examination of the aneurysm walls, with occlusion of the vasa vasora by inflammatory infiltrate or edema being a prominent feature. Culture of the aneurysm wall or thrombus yielded positive results in two patients. The association between HIV and aneurysms may be coincidental, caused by direct viral action or by bacterial infection resulting from immunosuppression. Implications for therapy are discussed, and the need for further study is highlighted. (+info)
Celiomesenteric anomaly with concurrent aneurysm. (7/984)We describe a rare case of a celiomesenteric anomaly with concurrent aneurysm. The patient, a 53-year-old man, had no abdominal pain or discomfort. The presence of a celiac artery aneurysm was suspected on the basis of the results of abdominal computerized tomographic scanning and echo ultrasound scanning performed because of proteinuria. Intra-arterial digital subtraction angiographic results showed the anomaly and aneurysm. Because of the risk of rupture of the aneurysm, the lesion was repaired surgically, with the placement of an interpositional prosthetic graft. We found no previous reports of celiomesenteric anomaly with concurrent aneurysm repaired with prosthetic graft. (+info)
Left subclavian artery aneurysm: two cases of rare congenital etiology. (8/984)Subclavian artery aneurysms are uncommon. The most common causes of these aneurysms are atherosclerosis and traumatic pseudoaneurysm. We report two cases of rare congenial left subclavian artery aneurysms. Diagnosis with aortography and treatment with resection with bypass grafting are the optimal approaches to avoid life-threatening and limb-threatening ischemia. (+info)
Isolated common femoral artery aneurysm: a case report | Cases Journal | Full Text
Primary femoral aneurysms are uncommon and are frequently associated with other aneurysms, particularly those of the aorta and popliteal arteries. True isolated atherosclerotic aneurysm of the superficial femoral artery is a rare pathology .. Rigdon et al discussed 17 arteriosclerotic superficial femoral artery aneurysms in 14 patients, which revealed complication at presentation in 65% - rupture in 35%, thrombosis in 18%, and distal emboli in 12%. However, limb salvage was 94% and there were no perioperative deaths . Males (75%) were more common than females, and the average age was 77 years (range 61 to 93) .. True femoral artery aneurysms are attributed to weakening of the arterial wall due to atherosclerosis. True femoral artery aneurysms are relatively rare and are found in elderly men who have strong smoking history. Aortic aneurysms are approximately 10 times more common. According to Levi et al distal embolization occurs in 0-26% of cases, acute thrombosis occurs in around 15% ...
Low pressure giant pulmonary artery aneurysms in the adult: natural history and management strategies | Heart
True pulmonary artery aneurysms are rare. Deterling and Clagett reported only eight cases in a review of 109 571 necropsies.2 Aggressive surgical approaches have often been advocated based on previous reports of dissection or rupture. Pulmonary artery aneurysms, even when very large, in the presence of low pulmonary pressures and the absence of left to right congenital or acquired shunts, may not pose such a risk in sharp contrast with those with pulmonary hypertension or Eisenmengers syndrome.3,4 Patients in this series all had low pulmonary arterial pressures, no significant congenital or acquired left to right shunts, and giant pulmonary artery aneurysms involving the main or proximal branch pulmonary arteries. They survived to a median age of 52 years without evidence of intimal tear or medial dissection and presented because of right ventricular dysfunction secondary to pulmonary regurgitation.. True aneurysms involve all components of the vessel wall.5 There may be associated intrinsic ...

Ruptured superficial femoral artery aneurysm treated by simple ligation | SMJ
A 79-year-old man, with a background of peripheral vascular disease, presented to the emergency department with a sudden increase in the size of his swelling in the right thigh, indicating rupture of his right superficial femoral artery aneurysm. His past medical history included having had a left femoropopliteal bypass (1986), abdominal aortic aneurysm repair (1991), repair of false aneurysm on the right (1992) and repair of left common femoral artery aneurysm (1995). On surgical exploration, four contiguous aneurysms in the right superficial femoral artery were identified, which measured around 25 cm in total length. After achieving control of the aneurysm, it was noted that the popliteal artery was unsuitable for anastomosis. However, the leg was still adequately perfused via collaterals in spite of the ligation, so nothing further was done. The patient was put on a heparin infusion postoperation, and had an uneventful recovery with a viable limb on discharge. It is a useful reminder that ...
Surgical Treatment of Multiple Vein Graft Aneurysms in 72 Year Old Man by Heather Geist, James K. Wu MD et al.
Abstract The rarity of saphenous vein graft aneurysms following coronary artery bypass graft surgery presents an interesting case, as seen in a 72 year-old gentleman who underwent his third bypass surgery for an aneurysmal graft. Information regarding the case was gathered using the Lehigh Valley Health Network medical databases. The 8 cm aneurysmal portion of the graft was resected successfully and replaced with a CryoVein. Following surgery the patient had relief of symptoms and recovered well. It was determined that the patient had two true aneurysms present, making surgery a necessity in this specific case. Introduction Saphenous vein graft (SVG) aneurysms following coronary artery bypass grafting (CABG) are rare but fatal complications that frequently require surgical repair.1 We address a rare surgical case regarding an individual requiring a third sternotomy involving two SVG aneurysms with thrombus, 22 years following CABG. Information was gathered retrospectively using the LVHN database. Case

Extracranial carotid artery aneurysm
Extracranial carotid artery aneurysms are uncommon and occur in a broad range of patients due to many etiologies. True aneurysms involving all layers of the carotid arterial wall and false aneurysms both occur. Overall, extracranial carotid artery an
Etiology of pulmonary venous aneurysm diagnosed by a combination of echocardiography and contrast-enhanced computed tomography:...
Pulmonary venous aneurysm is rare and its etiology is still debated. Some studies have shown that acquired aneurysms are caused by an increase in left atrial pressure and mitral regurgitation. However, few reports have provided direct evidence of this pathology. We present a case of pulmonary venous aneurysm diagnosed using a combination of echocardiography and contrast-enhanced computed tomography with strong evidence for an etiology of severe mitral valve regurgitation. A 24-year-old Chinese man was diagnosed with mitral valve perforation with severe mitral regurgitation caused by infectious endocarditis. A right inferior pulmonary venous aneurysm was diagnosed by contrast-enhanced computed tomography. Color Doppler echocardiography revealed a mitral regurgitation jet filling the giant aneurysm. Three-dimensional echocardiography provided a clear stereoscopic view of the aneurysm. These imaging modalities provided direct evidence for the etiology of the pulmonary venous aneurysm.

N2 - BACKGROUND: Idiopathic pulmonary artery aneurysm is a rare anomaly with only a handful reports in the literature. It is often asymptomatic, while the first presentation could be severe hemoptysis or death. Surgical intervention needs to be planned carefully with a multidisciplinary team approach to secure optimal outcome. We hope to spread our experience with such cases and to encourage other surgeons worldwide to deal surgically with these cases when its indicated.CASE PRESENTATION: A 47 years old man presented to our institution after three episodes of hemoptysis, echo demonstrated good left ventricle (LV) systolic function, normal right ventricle (RV) size and ...
Use of an amplatzer vascular plug in embolization of a pulmonary artery aneurysm in a case of hughes-stovin syndrome: a case...
The limited number of patients with identified Hughes-Stovin syndrome has precluded the initiation of controlled studies of the management of patients with pulmonary arterial aneurysms . Corticosteroids, alone or in combination with an immunosuppressant, are generally considered first-line therapy . Surgical resection has been the traditional treatment of choice when the risk of lethal hemoptysis necessitates more definitive therapy. Total pneumonectomy or lobectomy has been performed with some successful results .. The high morbidity associated with surgery and the frequent bilaterality and multifocality of the pulmonary artery aneurysms make transcatheter embolization an attractive alternative to surgery in most cases. To our knowledge, few patients with Hughes-Stovin syndrome have been treated by performing embolization of a pulmonary arterial aneurysm with the use of several agents, including steel coils, Ethibloc, and isobutyl cyanoacrylate, an epoxy [4, 6, 7].. This is the first ...

Background: The incidence of pulmonary artery aneurysm (PAA) in children remains unknown. There are few reports of a transcutaneous interventional approach to address this type of pathology. Management of PAAs while on VA ECMO has not been described in pediatrics. Objectives/Goal: Methods/Design: Case: 9-year-old previously healthy male presented with MRSA associated ARDS and sepsis requiring urgent VA ECMO cannulation. Chest CT done on ECMO day 22 showed development of right sided PAAs. Patient had an episode of significant pulmonary hemorrhage. Angiogram demonstrated two fusiform right PAAs, one of which had ruptured and was bleeding into the lung parenchyma. Patient had successful occlusion of the aneurysms with Amplatzer devices in the catheterization lab while on VA ECMO support. The procedure was complicated by flail tricuspid valve. Patient tolerated this complication and the procedure went well with no further hemorrhagic events. He decannulated from ECMO and was discharged from the PICU
Acute Leg Ischaemia in a Child due to a Thrombosed Popliteal Aneurysm - ePrints - Newcastle University
2018 The Authors Introduction: The case of an idiopathic thrombosed popliteal aneurysm is described in an otherwise healthy 6 year old child. This is the fourth reported case and the second youngest patient to present with an idiopathic isolated popliteal aneurysm. Report: A 6 year old boy presented with an acutely ischaemic right foot. Computed tomography angiography confirmed a thrombosed popliteal aneurysm. A femoropopliteal bypass was performed with reversed long saphenous vein and ligation of the aneurysm. Yearly follow up is ongoing with ultrasound surveillance; the childs growth and development is unaffected, and the graft is patent. There was a readmission over six years later with claudication on the right side. There was evidence of thrombus in the graft with associated distal embolisation, which was managed conservatively with anticoagulation. Discussion: Given the rarity of such presentations in the paediatric population, there is minimal good quality data to guide treatment. There ...
NewYork-Presbyterian Queens - Thoracic Aortic Aneurysm
The shape of an aneurysm is described as being fusiform or saccular which helps to identify a true aneurysm. A true aneurysm involves all three layers of the arterial blood vessel wall. The more common fusiform-shaped aneurysm bulges or balloons out on all sides of the aorta. A saccular-shaped aneurysm bulges or balloons out only on one side.. The aorta is under constant pressure from blood being ejected from the heart. With each heartbeat, the walls of the aorta expand and spring back, exerting continual pressure or stress on the already weakened aneurysm wall. Therefore, there is a potential for rupture (bursting) or dissection (separation of the layers of the thoracic aortic wall), which may cause life-threatening hemorrhage (uncontrolled bleeding) and, potentially, death.. Once formed, an aneurysm will gradually increase in size and there will be a progressive weakening of the aneurysm wall. Treatment for a thoracic aneurysm may include surgical repair or removal of the aneurysm to prevent ...

What does it mean to have a popliteal aneurysm rupture - Answers on HealthTap
Doctor answers on Symptoms, Diagnosis, Treatment, and More: Dr. Colantino on what does it mean to have a popliteal aneurysm rupture: An aneurysm is an dilitation of a blood vessel. This is the result of weakening in the wall of the artery. The weakened wall can rupture, and bleeding into the tissues around the knee occurs, causing tremendous pain and swelling. The blood outside the artery can then impinge on flow to the lower leg and foot, causing ischemia. In all, very bad, and one of the reasons to fix aneurysms electively. for topic: What Does It Mean To Have A Popliteal Aneurysm Rupture
Pattern of Extracranial Peripheral Aneur | AAS
Peripheral aneurysms are rarely reported in Africa (4). Reports from western countries indicate that they are rare, but considered important because their presence may point to the concurrent involvement of the abdominal aorta (1,2). In the present study for example, half of the cases of popliteal aneurysms presented with concurrent abdominal aortic aneurysms. The clinical features of pulsatile masses, painful swellings, pressure effects, bleeding and gangrene are consistent with literature reports (2,3,6). Similarly the diagnostic modalities of doppler ultrasound, angiography and CT are typical for reported series (7,8). Indeed the ultrasonography provides a non invasive and relatively inexpensive technique for accurate and prompt diagnosis of aneurysm (8). The result of site localization in this study is unique. The popliteal artery is the most common site of peripheral aneurysms in Caucasian populations, accounting for 70 - 85% of the total, followed by femoral artery (1,2,10-14). In the ...
Treatment of Popliteal Aneurysm by Open and Endovascular Surgery: A Contemporary Study of 592 Procedures in Sweden
WHAT THIS STUDY ADDS Previous comparisons between open and endovascular repair of popliteal aneurysms have focused on asymptomatic patients, and have short follow up. This study is strengthened by the fact that it is contemporary, population based, without any selection bias, reporting on all kinds of presentations, and has approximately 90% 1 year follow up data. It shows that endovascular repair has significantly inferior results compared with open repair, in particular in the group of patients who present with acute ischaemia. We believe these results will make many vascular surgeons think twice before they treat patients endovascularly in the future. Background: Popliteal aneurysm (PA) is traditionally treated by open repair (OR). Endovascular repair (ER) has become more common. The aim was to describe time trends and compare results (OR/ER). Methods: The Swedish vascular registry, Swedvasc, has a specific PA module. Data were collected (2008-2012) and supplemented with a specific protocol ...
Mesenteric Aneurysm Repair Merits a Vascular Surgeon - Bradenton, FL - Florida Surgical Clinic
Over the last several years there have been multiple advances in vascular surgery. One of these is the treatment of mesenteric aneurysms, which are treatable via both endovascular and open means. While the aneurysm itself may cause pain, it is often asymptomatic. Depending on the size and symptoms, an aneurysm may require treatment as if an aneurysm ruptures it can cause a person to quickly bleed to death.If the aneurysm is large, growing, or painful it will need to be treated. Also, splenic aneurysms in young women are or plan on becoming pregnant need to be treated as they have a higher risk of rupture.. A vascular surgeon will perform an aneurysm exclusion or open resection of a mesenteric aneurysm. The first step will be to better characterize the aneurysm and the blood vessels that surround it. Most commonly, patients have had another study such as computed tomography, which demonstrates the aneurysm. Occasionally, one is found on duplex ultrasound. Regardless, optimal visualization of the ...
Charcot-Bouchard aneurysm - Wikipedia
Charcot-Bouchard aneurysms (also known as miliary aneurysms or microaneurysms) are aneurysms of the brain vasculature which occur in small blood vessels (less than 300 micrometre diameter). Charcot-Bouchard aneurysms are most often located in the lenticulostriate vessels of the basal ganglia and are associated with chronic hypertension. Charcot-Bouchard aneurysms are a common cause of cerebral hemorrhage. If a Charcot-Bouchard aneurysm ruptures, it will lead to an intracerebral hemorrhage, which can cause hemorrhagic stroke, typically experienced as a sudden focal paralysis or loss of sensation. Charcot-Bouchard aneurysms are aneurysms in the small penetrating blood vessels of the brain. They are associated with hypertension. The common artery involved is the lenticulostriate branch of the middle cerebral artery. Common locations of hypertensive hemorrhages include the putamen, caudate, thalamus, pons, and cerebellum. As with any aneurysm, once formed they have a tendency to ...

Location and Incidence Rate of Anastomotic Aneurysms - own Clinical Material and Literature Review - Polish Journal of Surgery ...
Anastomotic aneurysms occurs at various levels of arterial system. Determining their location and incidence rate required investigation of large patient clinical material. Material and methods. In the years 1989-2010 in local centre 230 anastomotic aneurysms were operated in 180 patients. Results. For 187 (81.3%) patients anastomotic aneurysms were localised in the groin, while for remaining 43 (18.7%) they occurred in other localisations. In aortic arch branch they occurred four times (1.7), in descending aorta - three times (1.3%), in abdominal aorta - 14 (6.1%) and in iliac arteries - 6 (2.6%). While for anastomosis with popliteal artery they were diagnosed in 16 (7%) patients. Own clinical material was compared with literature data. Conclusions. Anastomotic aneurysms in over 80% of cases occur in the groin, remaining percentage corresponds to other localisations ...

False aneurysm of the common femoral vein in a footballer | British Journal of Sports Medicine
Venous aneurysms may be either congenital or acquired. Most acquired venous aneurysms develop secondary to a traumatic vascular injury.2-4 Traumatic injury to a particular venous segment may cause disruption and weakness in the vessel wall and gradually result in dilatation and aneurysm formation, either true or false. Peripheral venous aneurysms may be seen in both lower and upper extremities and most have little clinical significance.7 However, they may present with severe clinical pictures such as deep venous thrombosis and pulmonary embolism.8. DSA produced a false positive result in this case. The wrong preoperative diagnosis in this case may be a result of problems attributable to angiography. Like almost every other diagnostic modality, it has user and technique dependent aspects to it. An error in the chain of consecutive steps may have resulted in the misdiagnosis. The premature diagnosis based on colour Doppler ultrasound and early DSA images may have been altered by DSA examination at ...

Aneurysms of the popliteal artery are the most frequent ones among all peripheral aneurysms. They are mainly of atherosclerotic in origin and only 4% of the cases have different origin, such as: Marfan syndrome, syphilis, bacterial infection, Behçet-syndrome, trauma or entrapment syndrome of the popliteal artery. The medical condition usually becomes apparent in the 5th-7th decade of age and afflicts mainly men in a gender ratio of 30:1.. The most frequent severe complication of popliteal aneurysms is the acute thrombotic occlusion, which often has a dramatic course.. The timely diagnosis and treatment of the acute cases is decisive for the final result. Apart from the acute arterial occlusion, the popliteal aneurysm leads also to peripheral arterioerterial embolisms which can be asymptomatic.. We did not experience any amputation in the a froid operated cases, but we observed a persistence of the pre-existing intermittent claudication with invalidating consequences. The frequent permanent ...
NewYork-Presbyterian Queens - Renal Vascular Disease
Treatment of a renal artery aneurysm depends on factors such as the size and location of the aneurysm and whether or not symptoms are present. Certain types of small (less than two centimeters, or about three-quarters of an inch) aneurysms may not be treated, but may be observed for growth or development of other complications.. Larger aneurysms (greater than two centimeters, or three-quarters of an inch), dissecting aneurysms, aneurysms causing kidney ischemia (lack of blood flow to the kidney tissue) and hypertension, aneurysms that are growing larger, and aneurysms causing symptoms may be treated surgically.. Because of the increased risk for rupture (bursting), a renal artery aneurysm in a pregnant woman or a woman of childbearing age will generally be treated surgically.. ...
The objectives of this study were to investigate the consistency, patency, and natural history of a vein graft canine aneurysm model and to determine the effectiveness of various coil designs on inducing aneurysm thrombosis. Twenty-one sacculuslike aneurysms were created in mongrel dogs by anastomosing a vein pouch to the common carotid artery. The model produced wide-neck aneurysms with 100% patency. The canine vein graft aneurysm provided an excellent model for the evaluation of endovascular devices. Three types of specially designed platinum coils were placed in the aneurysms: those with simple curves, those with complex curves, and those with flower petal curves and silk fibers. These coils were placed by the endovascular route by means of microcatheters. Flower petal coils with silk fibers were effective in producing thrombosis of the aneurysms, suggesting that coils of the appropriate design may be useful in the endovascular treatment of aneurysms. The other coil designs evaluated, those ...

Aneurysms outside of the brain.. The most common location for an aneurysm to occur outside of the brain is in the main artery in the stomach-the abdominal aorta. Abdominal Aortic Aneurysms (AAA) can be lethal if not recognized and treated.. The normal size (diameter) of the abdominal aorta is approximately one inch (2.5 cm.) Typically an artery is recognized to have an aneurysm when its diameter increases by 50%, which would be about 1.5 or approximately 4cm from side to side. Arteries behave much like water balloons-that is, the bigger they get, the thinner they get. The thinner they get, the more chance there is of the artery popping or rupturing. A ruptured abdominal aortic aneurysm (AAA) is often fatal as the ruptured artery leads to massive internal bleeding and usually immediate death from exsanguination.. Smaller aneurysms are less likely to rupture than larger ones. Typically, when an aneurysm reaches 5cm, consideration is given to repairing the artery to prevent rupture. The exact ...

Results: In our experience, there were 47 males and the mean age was 62 years (16-80). In patients with PAAs and VAAs, technical success with the MFM was 100%. At 30 days, there were no deaths. Initial MFM patency was 97.5% (39/40) with patency of the thrombosed MFM successfully restored. Longer-term follow-up (mean 16±8 months) demonstrated progressive thrombosis and shrinkage of the aneurysm sacs and all side-branches were patent. In patients with aortic aneurysms, technical success was 100%, with no complications and no deaths at 30 days. Longer-term follow-up (8±7 months) demonstrated aneurysm-related survival of 100%, all-cause survival of 83.3%, intervention-free survival of 100% and 100% patency of the side branches. The longest duration for aneurysm sac thrombosis was 18 months.

OBJECTIVES: Medical therapies have not proven to be effective in halting or reversing the progressive dilation of aneurysms. Further, no therapy exists for small aortic aneurysms due to the significant risks of surgical repair. Smooth muscle cells (SMCs) have the ability to produce extracellular matrix (ECM) that is destroyed in the vessel wall during aneurysm formation. We hypothesized that polymeric nanoparticles bearing ascorbic acid (AA) and retinoic acid (RA) will be effective in reducing inflammation and promoting SMC synthesis of the ECM proteins, collagen and elastin, thus inhibiting aneurysm formation in vivo.. METHODS and RESULTS: Block co-polymer nanoparticles made of polyethylene oxide (PEO) and poly(ϵ-caprolactone) (PCL) capable of bearing both hydrophilic (AA) and hydrophobic (RA) drugs were fabricated by the formation of an organic/aqueous bi-phase stable emulsion. The particles were analyzed to ensure proper spherical morphology, nano diameter, and entrapment of drug prior to in ...
Endovascular aneurysm repair (Key hole s | Essex Veins
In endovascular repair, the aneurysm isnt removed. Instead, a graft is inserted into the aorta to strengthen it. This is done using catheters (tubes) inserted into the arteries; it doesnt involve surgically opening the chest or abdomen. General anaesthesia is used during this procedure.. . A catheter is inserted into an artery in the groin (upper thigh) and guided into the aneurysm. Then, using an x-ray to see the artery, the graft (also called a stent graft) is threaded into the aorta to the aneurysm.. . The graft is then expanded inside the aorta and fastened in place to form a stable channel for blood flow. The graft reinforces the weakened section of the aorta. This helps prevent the aneurysm from rupturing.. . Broomfield Hospital, Chelmsford, Essex - Where Mr Tom. Browne operates, is the only hospital in Britain to have a hybrid theatre where this procedure can be carried out using the most modern facilities. ...

Aortic Aneurysm An aneurysm is a bulge or ballooning in the wall of an artery. Arteries are blood vessels that carry oxygen-rich blood from the heart to other parts of the body. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death. Most aneurysms are in the infrarenal aorta (aorta below the kidney). The aorta is the largest artery in the body

Ruptured splenic artery aneurysm detected by emergency ultrasound-a case report | Critical Ultrasound Journal | Full Text
Splenic artery aneurysm (SAA) is defined as an abnormal dilatation of the splenic artery more than 1 cm in diameter. It was first described on cadavers in 1770 by Beaussier . It accounts for approximately 60 % of all visceral arterial aneurysms . It is the third most common intra-abdominal aneurysm, following aortic and iliac artery aneurysms . SAA is rarely seen with a prevalence of 1 % . It is four times more common in females compared to males [8-10]. Risk factors correlating to the development of SAA include fibromuscular dysplasia, collagen vascular diseases, female gender, history of multiple pregnancies, and portal hypertension, although the pathogenesis is not fully understood .. Splenic artery pseudoaneurysms are less prevalent than true SAA. They differ from true SAA in that the dilatation occurs following the disruption of one or more layers of the vessel wall. Splenic artery accounts for the majority of splanchnic pseudoaneurysms. Unlike true SAA, they have a slight ...

Intracranial aneurysm - Wikipedia
Intracranial aneurysm, also known as brain aneurysm, is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel. Aneurysms in the posterior circulation (basilar artery, vertebral arteries and posterior communicating artery) have a higher risk of rupture. Basilar artery aneurysms represent only 3%-5% of all intracranial aneurysms but are the most common aneurysms in the posterior circulation. Cerebral aneurysms are classified both by size and shape. Small aneurysms have a diameter of less than 15 mm. Larger aneurysms include those classified as large (15 to 25 mm), giant (25 to 50 mm), and super-giant (over 50 mm). Saccular aneurysms, also known as berry aneurysms, appear as a round outpouching and are the most common form of cerebral aneurysm. Fusiform dolichoectatic aneurysms represent a widening of a segment of an artery around the entire blood vessel, rather than just arising from a side of an arterys ...

Asaccular Aneurysm of the Ascending Aorta Following Coronary Artery Bypass Graft Surgery | MedCrave
An aneurysm is defined as dilatation of the artery greater than 50% in diameter. Aneurysms are categorized as fusiform or saccular. The saccular aneurysms of the ascending aorta are rarely seen and are usually life-threatening. Excessive use of biologicglue, graft infection, mediastinitis, aortic dissection, atherosclerosis, hypertension, degeneration of a penetrating atherosclerotic ulcer, poorsurgical technique, trauma, fungal infections and previous aortic surgery (presumably due to the cannulation site) are the etiologic risk factors for the development of a false or true aneurysm of the ascending aorta . There are a few reports for saccular aneurysm of the ascending aorta which are following coronary artery bypass grafting surgery. The wall stressis greater in saccular aneurysms rather than fusiform aneurysms. The disruption of the vesse lwall at the cannulation site oral long the aortic suture lines lead to saccular aneurysm..

Calcified wall portal venous aneurysm: a case report
Portal vein aneurysms are extremely rare, less than 200 cases have been reported until late 2015. They are defined as a portal vein diameter exceeding 19 mm for cirrhotic patients and 15 mm in normal livers. Most patients are asymptomatic, but complications may occur.We report a case of a 68-year-old female admitted for etiological assessment of a portal hypertension revealed by an upper gastro intestinal bleeding, who was incidentally diagnosed with a portal vein aneurysm.
FDA Panel Endorses Brain Aneurysm Device | Medpage Today
This is a transforming event in cerebrovascular surgery, said Nelson, who has implanted the device in about 75 patients in the U.S.. Large aneurysms, which measure between 10 mm and 25 mm, and giant aneurysms, which are greater than 25 mm in size, are rare, with about 2,000 reported cases each year. There is a greater risk of rupture with giant aneurysms, and they are much more difficult to treat.. Smaller, uniformly shaped aneurysms with small necks attaching them to the artery can be treated by surgically clipping the base of the aneurysm, or by pushing platinum coils into the aneurysms to initiate a clotting reaction. But clipping the base of an large aneurysm is very difficult and extremely risky, and often coils wont fit into an oddly-shaped aneurysm, explained Nelson.. The flexible Pipeline, which resembles a mesh tube, is inserted into the artery from which the aneurysm has developed. It works by cutting off the blood supply to the aneurysm, which, over time, eliminates the aneurysm ...
True posttraumatic aneurysm of the temporal artery
DISCUSSION. Traumatic arterial injuries have a high mortality rate and lead to severe complications. They can be caused by penetrating or blunt traumas or may be iatrogenic. Injuries can lead to rupture of arteries, hemorrhage, arterial occlusion, dissection and formation of pseudoaneurysms, true aneurysms or arteriovenous fistulas.3 Aneurysms of the superficial temporal artery are rare events and there are currently a total of around 200 cases reported in the literature.4 In 95% of cases, aneurysms of the temporal artery have traumatic origin and form pseudoaneurysms. The remaining 5-8% are congenital aneurysms or have atherosclerotic origin.5,6 A true traumatic aneurysm, involving all three layers of the vessel, is an extremely rare event. It is believed that true aneurysms may develop from a preexisting vascular condition, but this remains uncertain.7 The first case of temporal artery aneurysm was described in 1740 by Thomas Bartolin.2 In 1934, Winslow and Edwards collected 108 cases of ...
Clinical Significance of Routine Cerebral Angiography after Cerebral Aneurysm Surgery.
Of the 104 aneurysms, 9 (8.7%) had aneurysmal remnant on postoperative angiography. Incomplete clipping was intentionally performed in 4 aneurysms more than 10mm in size and in one basilar tip aneurysm. The remaining 4 aneurysms had unexpected remnant of sac, which was anterior choroidal artery aneurysm in 1 and anterior communicating artery aneurysms projecting superiorly or posterior-superiorly in 3. Thus, the true incidence of residual aneurysm was 3.8% (4/104 aneurysms). Logistic regression analysis showed the size of aneurysm as the only risk factor of residual aneurysm. Occlusion or narrowing of major artery was noted in 4.8%. Even though we had re-adjusted the clip in two cases because of parent arterial narrowing on postoperative angiography, two patients died due to cerebral infarction ...
PET/CT Imaging of Aneurysm Wall Inflammation - Tabular View - ClinicalTrials.gov
Rationale: Aneurysm development, progression and rupture are characterised by extensive inflammation, dominated by the infiltration of T-cells, B-cells and macrophages. Recent studies into the pathophysiology of aneurysm wall degradation suggest a close relation between increased mechanical stress and the local activation of infiltrated lymphocytes and macrophages. The non-invasive detection of aneurysm wall inflammation, using 18-fluorodeoxyglucose positron emission tomography (FDG-PET) might therefore provide valuable information on the extend of the disease and could clarify the role of mechanical stress on the propagation of aneurysm wall inflammation.. Objective: Correlation of FDG uptake and in vitro aneurysm wall tensile strength. (primary objective). The effect of aneurysm sac depressurisation, after endovascular aneurysm repair, on aneurysm wall inflammation (secondary objective).. Study design: Observational case series (pilot). Study population: Patients scheduled for conventional ...

Visceral vessel processes are primarily or secondarily included in a multitude of clinical abdominal symptoms, with which the specialist in internal medicine is confronted. The spectrum ranges from more sharply outlined manifestations, such as chronic ischemic bowel disease up to dysfunctional disturbances of blood pressure regulation, such as high-grade renal artery stenosis. Sometimes diseases with prognostic implications, such as arterial aneurysms, are revealed as incidental findings. As a rule the B‑mode and duplex ultrasound can often be complemented by computed tomography (CT) and magnetic resonance imaging (MRI), as in aneurysms or portal vein thrombosis or the indications for subsequent digital subtraction angiography (DSA) and catheter-based therapy can be directly obtained from duplex and Doppler ultrasound ...
Modeling of saccular aneurysm growth in a human middle cerebral artery
Saccular aneurysm growth in a human middle cerebral artery is modeled. The aneurysm growth model was presented in a companion paper by Kroon and Holzapfel (A Model for Saccular Cerebral Aneurysm Growth by Collagen Fibre Remodelling, J. Theor. Biol., in press) and was assessed there for axisymmetric growth. The aneurysm growth model is now evaluated for a more realistic setting. The middle cerebral artery is modeled as a two-layered cylinder, where the layers correspond to the media and the adventitia. An instant loss of the media in a region of the artery wall initiates the growth of the saccular aneurysm. The aneurysm wall is assumed to be a development of the adventitia of the original healthy artery, and collagen is assumed to be the only load-bearing constituent in the adventitia and in the aneurysm wall. The collagen is organized in a number of distinct layers where fibers in a specific layer are perfectly aligned in a certain fiber direction. The production of new collagen is taken to ...
Are Multiple Intracranial Aneurysms, More Than 5 At One Time, Almost Exclusively A Female Disease? A Clinical Series and...
The clinical characteristics of elderly patients with multiple IAs were studied in 481 patients by Inagawa . Patients were divided into two groups: group 1 - 59 years of age or younger and group 2- 60 years of age or older. Of the 481 patients, 136 (28%) had multiple aneurysms. The percentage of patients with multiple aneurysms was 30% for group 1 and 27% for group 2. The rate of multiple aneurysms was significantly less in males than in females (17% versus 31%). Due to the small sample size, no significant difference could be found between the male and female age groups in terms of the number of aneurysms by gender, yet it is important to highlight that there were no male patients reported in that series with 5 aneurysms or more. The only patients in this series reported to have 5 aneurysms or more were females; one patient in group 1 with 5 aneurysms and one with 6 aneurysms, and a single female patient with more than 5 aneurysms in group 2. Comparable findings were reported by Wilson et ...

Abdominal Aortic Aneurysm - Health Encyclopedia - University of Rochester Medical Center
About 3 out of 4 abdominal aortic aneurysms dont cause symptoms. An aneurysm may be found by X-ray, computed tomography (CT or CAT) scan, or magnetic resonance imaging (MRI) that was done for other reasons. Since abdominal aneurysm may not have symptoms, its called the silent killer because it may rupture before being diagnosed. Pain is the most common symptom of an abdominal aortic aneurysm. The pain associated with an abdominal aortic aneurysm may be located in the abdomen, chest, lower back, or groin area. The pain may be severe or dull. Sudden, severe pain in the back or abdomen may mean the aneurysm is about to rupture. This is a life-threatening medical emergency. Abdominal aortic aneurysms may also cause a pulsing sensation, similar to a heartbeat, in the abdomen. The symptoms of an abdominal aortic aneurysm may look like other medical conditions or problems. Always see your doctor for a diagnosis. ...
Cerebral Aneurysm | AdventHealth Neuroscience Institute
Oftentimes, brain aneurysms are not detected until they rupture or are found during medical imaging tests for other conditions.. If you experience a severe headache or other symptoms of an aneurysm, there are four types of tests your doctor may order to determine if your symptoms are the result of an aneurysm.. At the AdventHealth Neuroscience Institute, our doctors use the following tests to detect an aneurysm: Computed Tomography (CT) Scan. Fast and painless, a CT scan is usually the first test ordered for patients with aneurysm symptoms. A CT scan creates 2D images of the brain and skull - sometimes referred to as slices - using X-rays. Sometimes, a contrast dye is injected into the patients bloodstream before the CT scan to help locate an aneurysm. This is called a CT angiography (CTA) and it produces sharper and more detailed images of the blood flow in the arteries of the brain. A CTA can clearly determine the size, location and shape of both ruptured or unruptured aneurysms. Magnetic ...

Brain Aneurysm: The Symptoms and Treatment | Medical Wiki - Medical Jobs, Careers And Information
Treatment. Surgical clipping or coiling techniques are majorly used in the treatment of brain aneurysms. It is essential to note that not all aneurysms are amenable to both forms of treatment. Consulting a neurologist is of extreme importance.. Clipping:. The surgeon reaches the aneurysm by cutting out a portion of the skull (craniotomy) and then locates the injured blood vessel and inserts a clip across the aneurysm. This obstructs blood from entering the aneurysm and then leaking out, or incases of an un-ruptured aneurysm, stunts its growth.. Endovascular Coiling or Coil Embolization:. This treatment approach involves inserting a catheter into the femoral artery (in the patients leg) and steering it through the vascular system, into the brain and finally into the aneurysm. Small platinum coils are lined through the catheter and placed into the aneurysm, jamming blood flow into the aneurysm and preventing a fissure. This minimally invasive procedure can be performed under general ...
Abdominal Aortic Aneurysms
An aortic aneurysm is a dilation of a segment of the aorta where the wall of the vessel becomes thin and weak. The most common site involves the abdominal aorta below the arteries to the kidneys. The main risk of an aortic aneurysm is rupture. If the aneurysm ruptures, the chance for survival is very low. If the aneurysm is repaired before rupture, the chance of survival is very good. In general, an abdominal aortic aneurysm should be repaired when it reaches a size of 5 centimeters in diameter. On average, an aortic aneurysm will increase in size 0.5 centimeters per year. A more rapid rate of enlargement might lead us to recommend repair before the aneurysm reaches 5 centimeters. There are currently two acceptable methods used to repair an abdominal aortic aneurysm. The most common method involves making an incision in the abdomen and directly exposing the aneurysm. The involved section of aorta is completely replaced with a prosthetic fabric tube. This operation is highly effective at reducing ...

Experimental Models in Abdominal Aortic Aneurysm | IntechOpen
Abdominal aortic aneurysm (AAA) is a potentially fatal disease and survival rate is very low when rupture occurs. Experimental models related with abdominal aortic aneurysm are performed on intact and ruptured aneurysm (RAAA) models. By using AAA models; complex mechanisms of aneurysm formation, aneurysm progression, chance of rupture, preventative and treating methods are researched. Most commonly used methods for creating aneurysm are utilization of transgenic or knockout animals; intra/extraluminal pharmacologic treatments such as elastase, calcium chloride or angiotensin II; hyperlipidemic diet application and surgical interventions such as xenograft, stenosis or graft. Pathogenesis of aneurysm is predominantly examined on rodents whereas studies aimed at development of treatment modalities such as surgical or endovascular interventions are predominantly performed on large animals like rabbit, porcine or dog. Experimental studies modeling aneurysm rupture (RAAA) simulate shock (total hypoperfusion)

Coiling - Therapy of brain aneurysms - Heidelberg University Hospital
The red arrow in both illustrations shows an aneurysm (weak spot in vascular wall) of the right front cerebral artery (A. carotis interna right, front view). For the safe treatment of this aneurysm, a tubular metal mesh (stent) was first inserted in the vascular wall and precisely placed above the mouth of the aneurysm. The almost invisible stent is marked with green dotted lines on the right part of the illustration. On both of its ends, it is marked with visible dark markers which the green arrows are pointing out. The purpose of a stent in the treatment of aneurysms is to narrow the mouth of the aneurysm with a mesh. Then, the platinum coils can be inserted safely in the aneurysm through the mesh. The platinum coils seal the aneuryms and can, in difficult cases, be better held in the aneurysm due to the underlying stent. The platinum coils are inserted in the aneurysm via a very fine, tiny plastic tube (so-called micro-catheter) through the mesh. In this case, the path of the micro-catheter ...
Abstract 2731: CFD Reveals Hemodynamic Differences Between Unruptured And Ruptured Intracranial Aneurysms During Observation |...
Background and Purpose: Although various studies have been performed, the mechanism leading to the rupture of cerebral aneurysms has not yet been elucidated. Accurate assessment of cerebral aneurysm rupture risk is important because current treatments carry a small but significant risk that can exceed the small natural risk of rupture. Various hemodynamic parameters have been proposed for estimating the risk of rupture of cerebral aneurysms, with limited success. We evaluated several hemodynamic parameters to predict rupture in a dataset of initially unruptured aneurysms in which some aneurysms ruptured during follow-up observation.. Methods: Geometry of the aneurysm and blood vessels was extracted from CTA images and analyzed using a mathematical formula for fluid flow under pulsatile blood flow conditions. Fifty side-wall internal carotid posterior communicating artery (ICA-pcom) aneurysms and fifty middle cerebral artery (MCA) bifurcation aneurysms of medium size were investigated for Energy ...
Abdominal Aortic and Thoracic Aneurysms - Savannah Vascular Institute
The aorta is the largest artery in your body, and it carries blood away from your heart. Your aorta runs through your chest, where it is called the thoracic aorta. When it reaches your abdomen, it is called the abdominal aorta. The abdominal aorta supplies blood to the lower part of the body. Just below the abdomen, the aorta splits into two branches that carry blood into each leg. An aneurysm is a weakened and bulging area of a blood vessel. If an aneurysm ruptures, it causes internal bleeding with a less than one in five chance of survival. Abdominal aortic aneurysms are associated with more than 15,000 deaths per year in the United States. In a large study performed by the Veterans Administration, abdominal aneurysms were found in four percent of men and one percent of women over the age of 50 years. The highest risks for aneurysms are in men, active and former smokers and family history of aneurysms. The risk of rupture increases sharply as the aneurysms grow. Screening for aneurysms and ...
Northern Light Health - Aortic Abdominal Aneurysm (AAA)
Arteries are the tubes carrying blood from the heart to the rest of the body. An aneurysm is a weak area in the wall of an artery that can bulge like a balloon, and can cause problems related to either bleeding or blood clotting. Aneurysms can occur throughout the body, but one of the most common locations is in the aorta. The aorta is the largest artery of the body, carrying blood directly from the heart through the chest and abdomen to the rest of the body.. Aneurysms of the aorta are worrisome because they can burst or rupture resulting in excessive bleeding and usually causing death. A small aneurysm may require no immediate treatment other than watchful waiting. The aneurysm should be monitored by a vascular specialist who will order periodic ultrasound exams or other tests to make sure that the aneurysm is not growing. Many times aneurysms remain small and pose no significant problems.. If an aneurysm reaches a certain size between 5 and 5.5 cm, your healthcare provider may refer you for ...

Results The aneurysm growth probability was 2.6±0.1% per year. The rate of unexpected aneurysm rupture before treatment was 0.24% per year (95% CI 0.17% to 2.40%). The calculated rate of aneurysm rupture after growth was 6.3% per aneurysm-year (95% CI 1% to 22%). Aneurysms located in the posterior circulation and aneurysms with lobulation were more likely to grow. Females or patients suffering hypertension were more likely to have an aneurysm growing. The probability of aneurysms growth increased with the size of the dome and was proportional to the number of aneurysms diagnosed in a patient. ...
Aneurysm - Wikipedia
Aneurysmal blood vessels are prone to rupture under normal blood pressure and flow due to the special mechanical properties that make them weaker. To better understand this phenomenon, we can first look at healthy arterial vessels which exhibit a J-shaped stress-strain curve with high strength and high toughness (for a biomaterial in vivo). Unlike crystalline materials whose linear elastic region follows Hookes Law under uniaxial loading, many biomaterials exhibit a J-shaped stress-strain curve which is non-linear and concave up. The blood vessel can be under large strain, or the amount of stretch the blood vessel can undergo, for a range of low applied stress before fracture, as shown by the lower part of the curve. The area under the curve up to a given strain is much lower than that for the equivalent Hookean curve, which is correlated to toughness. Toughness is defined as the amount of energy per unit volume material can absorb before rupturing. Because the amount of energy released ...
Randomized Comparison of Guglielmi Detachable Coils and Cellulose Acetate Polymer for Treatment of Aneurysms in Dogs | Stroke
These results show that aneurysm treatment with CAP has a higher likelihood of producing arterial thrombosis and a lower likelihood of obliterating the aneurysm than aneurysm treatment with GDC. If CAP is allowed to overflow into the feeding or branch artery, thrombosis of these arteries generally occurs. If it remains in the aneurysm, there is some chance of the CAP dissolving and the aneurysm reforming. This may be prevented by mixing the CAP with less dimethyl sulfoxide (H. Ohmoto, personal communication, March 1997). The problems with GDC tend to be the opposite. There were no arterial thromboses, despite the coils protruding into the arterial lumen to some extent in some cases. The aneurysm, however, only obliterated and filled with solid tissue approximately 63% of the time.. Previous studies of CAP have produced more favorable results. In two experimental studies, 29 sidewall aneurysms were able to be completely obliterated in dogs with a risk of arterial occlusion of approximately 13% ...
Why Are Women More Likely to Have Brain Aneurysms Compared to Men? - - Prova Education
Photo: MriMan/Shutterstock.com news-medical.net A brain aneurysm is a diseased or abnormal dilatation of the cerebral arteries at a weak spot. These typically thin-walled aneurysmal sacs of blood may continue to enlarge because of the force of the arterial pulsatile flow. A ruptured aneurysm leads to a subarachnoid hemorrhage, an SAH. Skewed Gender Representation in Aneurysm Formation Worldwide, cerebral aneurysms occur in 3.2% of the global population, with the mean age of presentation being 50 years. Scientists estimate that over 6 million Americans have an unruptured aneurysm in the brain, and about 30,000 of them rupture each year. In 40 of each hundred ruptures, the patient dies. Brain aneurysms are more common in females by about 60% overall, and more especially in the postmenopausal age group, where the risk is more than twice as high. This has prompted the hypothesis that sex hormones are involved in the formation of aneurysms. This may be the reason, some say, that women are protected

Celiac trunk aneurysm is a rare finding. Most patients are symptomatic at the time of diagnosis but occasionally such aneurysms are detected incidentally during diagnostic imaging for other diseases. Since the anomaly was first described in 1745(1) fewer than 180 cases have been reported in the international medical literature.(2) Atherosclerotic aneurysms of the celiac artery (CAAs) comprise approximately 4-6% of all visceral aneurysms.(3-4) Early surgical intervention has reduced the rupture rate to 7% in recent years.(5) Early recognition and intervention are crucial because the operative mortality rate associated with ruptured celiac artery aneurysms is around 40%.(6) There are no absolute size criteria associated with significant rates of CAA rupture, but 2 cm appears to warrant intervention in most series.(7-8) Surgical reconstruction, surgical ligation, intraluminal embolization, thrombin injection and endovascular grafting have all been reported with success/9
aneurysm model [Operative Neurosurgery]
Experimental saccular aneurysm models are necessary for testing novel surgical and endovascular treatment options and devices before they are introduced into clinical practice. Furthermore, experimental models are needed to elucidate the complex aneurysm biology leading to rupture of saccular aneurysms. Several different kinds of experimental models for saccular aneurysms have been established in different species. Many of them, however, require special skills, expensive equipment, or special environments, which limits their widespread use. A simple, robust, and inexpensive experimental model is needed as a standardized tool that can be used in a standardized manner in various institutions. The microsurgical rat abdominal aortic sidewall aneurysm model combines the possibility to study both novel endovascular treatment strategies and the molecular basis of aneurysm biology in a standardized and inexpensive manner. Standardized grafts by means of shape, size, and geometry are harvested from a ...
Response to editorials. Saccular aneurysms in the Barrow Ruptured Aneurysm Trial: 10 years later in: Journal of Neurosurgery...
These data demonstrate not only that the assigned cohorts were the same as in our publication but also that the actually treated aneurysms had similar outcomes. Despite the inclusion of more-difficult aneurysms that were assigned to endovascular coiling but were actually treated with clipping, plus those actually treated with clipping because of large hematomas, the results demonstrate a slight, although statistically nonsignificant, benefit to clipping. Thus, from a pool of 314 randomized patients, all those randomized to undergo clipping (with the exception of a single patient) had their aneurysms actually clipped, and in addition, 36% of cross-over patients who were randomized to undergo coiling had their aneurysms actually clipped. This finding emphasizes that the use of clipping to treat all anterior circulation aneurysms could achieve results equal to those for the selected anterior circulation coiling treatment cohort.. The lack of middle cerebral artery (MCA) aneurysms in the cohorts ...
AI helps detect brain aneurysms on CT angiography | Green Health Live
A powerful type of artificial intelligence known as deep learning can help physicians detect potentially life-threatening cerebral aneurysms on CT angiography, according to a study published in the journal Radiology.. Cerebral aneurysms are weakened areas of blood vessels in the brain. Left untreated, they can leak or rupture, with sometimes fatal results. Detection and characterization of these aneurysms are critical, as the risk of rupture depends on the size, shape and location of the aneurysm.. CT angiography is usually the first choice for evaluating cerebral aneurysms. The exam is highly accurate, but cerebral aneurysms can be overlooked on the initial assessment due to their small size and the complexity of the blood vessels in the brain.. In our daily work we are always faced with cases in which some important lesions have been missed by the human eye, said study senior author Xi Long, Ph.D., from the Department of Radiology at Tongji Medical Colleges Union Hospital in Wuhan, China. ...

Evidence That a Subset of Aneurysms Less Than 7 mm Warrant Treatment | Journal of the American Heart Association
The physiopathology that leads to the development of aneurysms and their subsequent rupture has been partially explained by hemodynamic components in a multitude of studies; high wall shear stress seems to play the predominant role in high‐flow aneurysm, whereas high intra‐aneurysmal pressure and low‐flow stasis are the main factors in low‐flow aneurysms.25 It is hypothesized that the lower the flow, the higher the degenerative changes, and the higher the risk of rupture. Ruptured aneurysms (RAs) can have areas with higher than average and more concentrated wall shear stress with smaller impingement zones (where the inflow jet impacts against the aneurysm wall) when compared with unruptured ones.26, 27, 28 Furthermore, it is reported that hemodynamic variables are dependent on the morphology of the aneurysm and on its feeding vessels.25, 29, 30 Chronic hypertension seems to play a major role in aneurysm formation since it is more prevalent in patients with CAs compared to the general ...
Predicting intraprocedural rupture and thrombus formation during coiling of ruptured anterior communicating artery aneurysms. -...
BACKGROUND Intraprocedural rupture and thrombus formation are serious complications during coiling of ruptured intracranial aneurysms, and they more often occur in patients with anterior communicating artery (ACoA) aneurysms. OBJECTIVE To identify independent predictors of intraprocedural rupture and thrombus formation during coiling of ruptured ACoA aneurysms. METHODS Between January 2008 and February 2015, 254 consecutive patients with 255 ACoA aneurysms were treated with coiling. We retrospectively reviewed intraoperative angiograms and medical records to identify intraprocedural rupture and thrombus formation, and re-measured aneurysm morphologies using CT angiography images. Multivariate logistic regression models were used to determine independent predictors of intraprocedural rupture and thrombus formation. RESULTS Of the 231 patients included, intraprocedural rupture occurred in 10 (4.3%) patients, and thrombus formation occurred in 15 (6.5%) patients. Patients with smaller aneurysms more
