Intimal angiosarcoma is a rare malignant vascular tumor with an aggressive natural history. Presenting symptoms vary according to the location of the lesion, but symptoms are typically due to intravascular obstruction or embolization. We present a case of an intimal angiosarcoma presenting with a common femoral artery aneurysm.

OBJECTIVE: Bicuspid aortic valve (BAV) is associated with aortic root and ascending aorta aneurysm and increased risk for aortic dissection. Guidelines recommend transthoracic echocardiography (TTE) for primary aortic evaluation, although cardiac magnetic resonance (CMR) may be superior at detecting abnormalities. This study compares TTE and CMR imaging for aortic evaluation ...

Segmental arterial mediolysis (SAM) is a rare, non-inflammatory, non-atherosclerotic vasculopathy typically affecting the abdominal arteries although it may also affect the great vessels and cerebral vasculature. Diseased vessels manifest with aneurysms and/or dissections, often presenting clinically with catastrophic thromboembolic injury and less frequently with subarachnoid hemorrhage (SAH). The etiology of ...

Advanced carotid atherosclerosis with severe stenosis (>70%) is a major clinical risk factor for ischemic stroke. Our ability to test new protocols for the treatment of atherosclerotic stenosis in humans is limited for obvious ethical reasons; therefore, a suitable animal model is required. The aim of this study was to ...

It is the ultimate goal of tissue engineering: an autologous tissue engineered vascular graft (TEVG) that is immunologically compatible, nonthrombogenic, and can grow and remodel. Currently, native vessels are the preferred vascular conduit for procedures such as coronary artery bypass (CABG) or peripheral bypass surgery. However, in many cases these ...

The pathogenesis of sudden sensorineural hearing loss (SSNHL) is unclear, though some researchers postulate the major mechanism of onset to be via circulatory disturbance or cochlear inflammation. SSNHL can represent the sole manifestation of anterior inferior cerebellar artery infarction, and patients with a SSNHL may have higher than normal risk ...

BACKGROUND: The posterior intercostal artery (PICA) is divided into four segments, vertebral, costal, intermuscular, and rectus, based on the neurovascular branching pattern. Dorsal branches arise from the vertebral segment. Several musculocutaneous perforators and a lateral branch originate from the costal segment. Musculocutaneous branches arise from the intermuscular and rectus segments. ...

BACKGROUND:: In the absence of a specific test, the diagnosis of clinically incomplete Kawasaki disease (KD) can be challenging. The 2004 American Heart Association guidelines state that the diagnosis of KD is supported by the presence of coronary artery dilation documented by echocardiography. However, the specificity of coronary artery dilation ...

BACKGROUND: Intracranial arterial dolichoectasia is a condition in which arteries demonstrate an increase in length and diameter, with the vertebrobasilar system being the most commonly affected segment. Because the criteria for and degree of vertebrobasilar dolichoectasia are usually established on three-dimensional time-of-flight MR angiography, we presented the results of an ...
