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.
Patient care procedures performed during the operation that are ancillary to the actual surgery. It includes monitoring, fluid therapy, medication, transfusion, anesthesia, radiography, and laboratory tests.
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.
Surgery performed on the heart.
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.
Pathological conditions in the DUODENUM region of the small intestine (INTESTINE, SMALL).

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)

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 [2].. 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 [3]. Males (75%) were more common than females, and the average age was 77 years (range 61 to 93) [3].. 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% ...
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 ...

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 ...
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

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.

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 [3]. Corticosteroids, alone or in combination with an immunosuppressant, are generally considered first-line therapy [4]. 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 [5].. 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
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 ...
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 ...

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
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 ...
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 ...
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 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.[citation needed] As with any aneurysm, once formed they have a tendency to ...

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 ...

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 ...
Development of aspergilloma is common in cases with a fungus ball-like shadow in cavities due to old tuberculosis. Some reports have shown that blood clots tend to appear as a fungus ball-like shadow. A 71-year-old man with a history of pulmonary tuberculosis presented with a fungus ball-like shadow in an old cavity and hemoptysis. There was no evidence of aspergillus infection on various examinations. We confirmed a blood clot and aneurysm of an artery under direct vision by bronchoscopy. A lateral thoracic artery aneurysm was detected by angiography ...
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 ...
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 ...

N2 - Of 25 patients with chronic leukemia, there was clinical evidence of peripheral retinal microaneurysm formation in two of eight patients with chronic lymphocytic leukemia and six of 17 patients with chronic myelogenous leukemia. There was no proliferative retinopathy in any of the 25 patients. An elevated leukocyte count seemed necessary for microaneurysm formation in leukemia, although some patients with elevated counts had no microaneurysms. The prolonged leukocytosis of chronic leukemia can produce peripheral capillary dropout, vascular stagnation, microaneurysm formation, and, rarely, peripheral proliferative ...
Circulatory Failure and Lactic Acidosis Associated with Giant Saphenous Vein Graft Aneurysm, Rick Mooi, Carsten Arnoldussen and Jos le Noble
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. A significant mean diameter reduction was observed at 6 months (17.3 mm for the transversal maximal diameter and 13.83 mm for the antero-posterior diameter) in the TAAA group. In the literature review, there ...

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 ...
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

Subclavian artery aneurysms are relatively rare in comparison with other peripheral aneurysms. We report a 65-year-old woman with multiple atherosclerotic aneurysms of the subclavian artery, aortic arch saccular aneurysm and abdominal aortic aneurysm
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 [7]. It accounts for approximately 60 % of all visceral arterial aneurysms [2]. It is the third most common intra-abdominal aneurysm, following aortic and iliac artery aneurysms [3]. SAA is rarely seen with a prevalence of 1 % [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 [11].. 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 ...

Although pulmonary artery aneurysms are a rare vascular anomaly, they are seen in a wide variety of conditions, such as congenital heart disease, infection, trauma, pulmonary hypertension, cystic medial necrosis and generalized vasculitis. To our kno
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 ...
A case of ruptured gastroepiploic artery aneurysm associated with thoracic aortic aneurysm is presented. Gastroepiploic artery aneurysms are rare, but the association of visceral artery aneurysm and aortic aneurysm is clinically significant and is emphasized in this report.
Congenital true aneurisms of peripheral arteries especially on the hand are rare and idiopathic. The present case is focused on the multiple aneurysms of a young boy on both radial and ulnar arteries since birth. The clinical indications include painful ulcers on the right middle finger, discoloration and swelling of dorsum of ulnar side of right hand. In addition, patchy necrosis of fifth finger with increased intensity of pain was observed. Here we successfully treated both aneurysms with partial amputation of the digit and the growth of the skin on both sides of the palm was restored by groin flap.
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 [1]. 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.. Theaortic false aneurysm may surrounded and restricted by ...

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.
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 ...
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 ...
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 ...
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 ...
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 ...
The clinical characteristics of elderly patients with multiple IAs were studied in 481 patients by Inagawa [31]. 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 ...

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. ...
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 ...

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 ...
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 ...
Brain aneurysm repair is a surgical procedure used to treat a bulging blood vessel in the brain thats at risk of rupturing or tearing open. In general, most brain aneurysms are small, rarely cause symptoms and have a very low risk of rupture. Feb 8, 2016 - My precious friend Peggy lost her life at 58 years of age to a Brain Aneurysm. The brain has very high oxygen and nutrient requirements and the flow of blood to the brain is critical. Symptoms may occur if the aneurysm is large or if it causes pressure on the structures, such as nerves or meninges (the three-layered covering over the brain), around it. About brain aneurysms. Brain aneurysm repair is surgery to correct an aneurysm. top. Researchers found that straining to defecate can cause over a seven-fold increase in the risk of a brain bleed.

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)
110 Francis St. Boston, MA 02215 P 617-632-9940. An aneurysm is an outward bulging, likened to a bubble or balloon, caused by a localized, abnormal, weak spot on a blood vessel wall. A ruptured brain aneurysm is a medical emergency and the clinical team will move quickly. The OHSU Brain Institute is a national leader in diagnosing and treating brain aneurysms. It involves opening the skull by removing a small piece of bone to have open access to locate the aneurysm. An aneurysm in the brain is a weak area in an artery in the brain that bulges out and fills with blood. The Neurological Institute is a leader in treating and researching the most complex neurological disorders and advancing innovations in neurology. An aneurysm in the brain is a weak area in an artery in the brain that bulges out and fills with blood. The neurosurgeon removes a section of your skull to access the aneurysm and locates the blood vessel that feeds the aneurysm. Some unruptured aneurysms need to be surgically repaired, ...
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 ...
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 ...
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 ...
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. ...
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).[34] 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.[34] 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 ...
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% ...
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
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 ...
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 ...
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. ...
An aneurysm is a localized ballooning in an artery due to a weak portion of the vessel wall. A ruptured aneurysm can cause hemorrhaging that is severely debilitating or fatal. The two most medically significant aneuryms occur at the base of the brain (intracranial aneurysms) and in the artery coming out of the heart (aortic aneurysms) Wikipedia. The most common type of aortic aneurysm is abdominal aortic aneurysm (AAA).

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 ...
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
