Intracranial Aneurysm: 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)Aneurysm: Pathological outpouching or sac-like dilatation in the wall of any blood vessel (ARTERIES or VEINS) or the heart (HEART ANEURYSM). It indicates a thin and weakened area in the wall which may later rupture. Aneurysms are classified by location, etiology, or other characteristics.Aneurysm, Infected: Aneurysm due to growth of microorganisms in the arterial wall, or infection arising within preexisting arteriosclerotic aneurysms.Aortic Aneurysm: An abnormal balloon- or sac-like dilatation in the wall of AORTA.Heart Aneurysm: 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: An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA. This proximal descending portion of aorta gives rise to the visceral and the parietal branches above the aortic hiatus at the diaphragm.Aneurysm, Dissecting: 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.Iliac Aneurysm: Abnormal balloon- or sac-like dilatation in the wall of any one of the iliac arteries including the common, the internal, or the external ILIAC ARTERY.Embolization, Therapeutic: A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli.

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.Aortography: Radiographic visualization of the aorta and its branches by injection of contrast media, using percutaneous puncture or catheterization procedures.Vascular Surgical Procedures: Operative procedures for the treatment of vascular disorders.Treatment Outcome: Evaluation undertaken to assess the results or consequences of management and procedures used in combating disease in order to determine the efficacy, effectiveness, safety, and practicability of these interventions in individual cases or series.Surgical Instruments: Hand-held tools or implements used by health professionals for the performance of surgical tasks.Stents: Devices that provide support for tubular structures that are being anastomosed or for body cavities during skin grafting.Angiography: Radiography of blood vessels after injection of a contrast medium.Postoperative Complications: Pathologic processes that affect patients after a surgical procedure.

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 TextIsolated 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 [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% ...
Low pressure giant pulmonary artery aneurysms in the adult: natural history and management strategies | HeartLow 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 | SMJRuptured 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."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

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 ...

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 AneurysmNewYork-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 ...

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 ...

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 ...
Charcot-Bouchard aneurysm - WikipediaCharcot-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.[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.

NewYork-Presbyterian Queens - Renal Vascular DiseaseNewYork-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 ...

... 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 retinopathy similar to sickle cell disease..

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 ...

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

Diabetes is a negative risk factor for aortic aneurysm, but the underlying explanation for this phenomenon is unknown. We have previously demonstrated that Cell Division Autoantigen 1 (CDA1), which enhances TGF-β signaling, is upregulated in diabetes. We hypothesized that CDA1 plays a key role in conferring the protective effect of diabetes against aortic aneurysms. Male wildtype, CDA1 knockout, Apolipoprotein E (ApoE) knockout and CDA1/ApoE double knockout (dKO) mice were rendered diabetic. Whereas aneurysms were not observed in diabetic ApoE knockout and wildtype mice, 40% of diabetic dKO mice developed aortic aneurysms. These aneurysms were associated with attenuated aortic TGF-β signaling, reduced expression of various collagens as well as increased aortic macrophage infiltration and matrix metalloproteinase12 expression. In the well characterized model of angiotensin II (AngII) induced aneurysm formation, concomitant diabetes reduced fatal aortic rupture and attenuated suprarenal aortic ...

Aortic aneurysms are inherently unpredictable. One can never be sure whether any given aneurysm may rupture or dissect. Clinically, the criteria for surgical intervention are based on size and growth rate, but it remains difficult to identify a high-risk aneurysm, which may require intervention before the cutoff criteria, versus an aneurysm than can be treated safely by more conservative measures. In this work, we created a computational microstructural model of a medial lamellar unit (MLU) incorporating (1) growth and remodeling laws applied directly to discrete, individual fibers, (2) separate but interacting fiber networks for collagen, elastin, and smooth muscle, (3) active and passive smooth-muscle cell mechanics, and (4) failure mechanics for all three fiber types. The MLU model was then used to study different pathologies and microstructural anomalies that may play a role in vascular growth and failure. Our model recapitulated many aspects of arterial remodeling under hypertension with no ...

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 ...
