Abstract:
Aneurysmal venous dilatation is a frequent complication of arterio venous fistulas (AVFs) created for hemodialysis. Venous aneurysm rupture can lead to lethal hemorrhage. A 49-year-old male patient presented with a giant aneurysmal dilatation of his AVF 10 years after its creation. The patient had complaints of pulsating pain and discomfort due to swelling of the left forearm. We performed an aneurysm resection and revised the overlying dermal lesion through a brachial plexus block. Here, we describe the pathological features of the arterialized venous aneurysm compared to simple venous aneury

Abstract:
Arteriovenous fistula is considered the “ideal vascular access” in patients with end stage renal disease (ESRD); however, its creation is not without complications. Aneurysmal dilatation is a poorly defined complication which, can potentially lead to access loss and life threatening hemorrhage. Increased venous pressure due to proximal venous stenosis along with repeated cannulations at the same site, are thought to play a significant role in pathogenesis. Given risk of substantial bleeding, it is recommended to avoid cannulation of aneurysmal area; however, as seen in our patient significant

SUMMARYIn the following study, a case involving an aneurysmal dilatation of the portal vein is reported. The 5‐year‐old boy had a 2 month history of intermittent abdominal pain. A segmental dilatation of the portal vein was noted in the sonographic examination. The portal vein aneurysm diagnosis was later confirmed by superior mesenteric angiography and computed tomography. In our review of the literature, less than 30 cases of portal venous aneurysm have been reported. To our knowledge, this is the youngest case with such an anomaly.

Giant basilar aneurysm is associated with various complications particularly brain stem infarction. It is emphasized that arteriosclerosis plays an important role in the formation of giant basilar aneurysms.

Abstract:
Peripheral arterial disease is defined as an alteration to the blood supply to a limb, caused by an occlusion or stenosis in the arteries supplying that limb. The acuteness of the arterial compromise, and its severity and extent, will determine the symptoms experienced by the patient. Aneurysmal disease is defined as a localized dilatation of an artery and is most commonly seen in the infrarenal abdominal aorta. An infrarenal abdominal aorta is defined as being aneurysmal if its maximum anteroposterior diameter is 3 cm or greater.

Abstract An aneurysm is a dilatation on a blood vessel,1 usually an artery. Many different types of aneurysms affect the nervous system (Table 3-1). The most common type is a saccular or ovoid protrusion attached by a small neck to the artery of origin, historically called a “berry.” Ruptured aneurysms account for most cases of subarachnoid hemorrhage (SAH), and the incidence of aneurysmal SAH is directly related to age. Aneurysmal rupture is extremely uncommon in infancy, becoming steadily less so during aging. For this reason the term “congenital” applied to aneurysms is a misnomer.

Abstract An aneurysm is a permanent balloon-like, blood-filled dilatation on an arterial vessel. In an abdominal aortic aneurysm (AAA), the growth and eventual rupture of aneurysmal lesions depends on the interaction between the aneurysm wall and the blood motion along it. Rupture of an aneurysm occurs when the shear stresses exceed the strength of the wall [1]. When an AAA ruptures, 50 percent of patients die before reaching the operating room and 54 percent of the remaining will die within 30 days [2]. Therefore, AAA represents a great danger to the patient [3]. The objective of this study i

Abdominal aortic aneurysm (AAA) is a pathological condition of the infrarenal aorta characterized by a local dilatation of the arterial wall. The main histopathologic features of an AAA are smooth muscle cell death and loss of elastin. The biomechanical behavior of AAAs has been widely studied to determine the rupture potential according to the principles of material failure. However, most prior approaches are limited by the use of data from uniaxial tensile testing and by the assumption of material isotropy, leading to inaccurate characterization of the 3D multiaxial mechanical response of th

Aortic aneurysm is a pathological dilatation of the aorta that can be life-threatening when it ruptures. Aneurysms occur throughout the entire aorta but there is a predisposition for the ascending and the abdominal aorta, an observation that cannot be fully explained by the current knowledge of the disease pathophysiology. ApoE −/− mice infused with angiotensin II have recently been reported to develop not only abdominal [1], but also ascending aortic aneurysms [2]. These animals thus provide the perfect model to compare aneurysm progression in both aortic locations and to investigate whether

Abstract:
Aneurysms are abnormal dilatations of arteries, and these lesions are found almost exclusively in humans. Saccular cerebral aneurysms occur most frequently in the Circle of Willis, which is a circuit of arteries supplying the brain with blood. Aneurysms of this kind appear in a few percent of the human population in the Western world. Only a few percent of these lesions do actually rupture, but once rupture occurs the consequences are severe, often with death as outcome. Once a cerebral aneurysm is detected, clinicians need to decide whether operation is required or not. These decisions are ma

Abstract:
Cerebral aneurysm (CA) is a localised dilatation in the wall of the brain vasculature which can cause it to swell out like a balloon. If not treated, it will continue to grow and eventually tear or rupture, resulting in severe disability from stroke and, in around 25% of cases, death [1]. CAs affect up to 5% of the adult population with 1% of detected aneurysms rupture every year [2].

Abstract:
Abstract Fluid-structure interaction studies were performed on various abdominal aortic aneurysm (AAA) models under the pulsatile flow condition. Eight aneurysm models were made with four different dilatation sizes and two different wall thickness. Stresses and deformations of the aneurysm wall were significantly affected by the dilatation size as well as the wall thickness. The change in wall thickness increased with the more dilated aneurysm. In spite of considerable radial deformations, axial deformations of the aneurysm wall were dominant. The present study showed the strong possibility to

Abstract:
Marfan syndrome (MFS) is a genetic connective tissue disorder with a high prevalence of aortic aneurysm formation (a pathological dilatation of the aorta), typically at the aortic root. The disorder is caused by mutations in the gene encoding fibrillin-1 [1]. Recently, it has been shown in mouse models that selected manifestations of MFS, such as aortic aneurysm formation, can be explained by excessive signaling by the transforming growth factor–beta (TGF-beta) family of cytokines [2]. Although the footprint of the disease is clearly genetic, there is still a role for (computational) biomechan
