A persistent sciatic artery (PSA) is a rare congenital anomaly, usually associated with hypoplasia of the iliofemoral system. In most cases, the sciatic artery is the main dominant inflow vessel to the lower extremity. Persistent sciatic artery is strongly associated with aneurysmal disease, with a high potential for thromboembolic events. ...

Aortic aneurysms remain a common medical condition in the twenty-first century. Although surgical repair remains the standard of care for patients with enlarging and advanced aneurysmal disease, new insights into the pathogenesis of aortic aneurysm have resulted in an interest in targeting these pathways and reducing the rate of aneurysm ...

Persistent sciatic artery (PSA), a persistent embryologic continuation of the internal iliac artery, represents a rare yet clinically important vascular anomaly. PSA is prone to aneurysmal change, which can subsequently lead to distal embolization, sciatic neuropathy, or rupture. The conventional surgical treatment of PSA aneurysms is commonly complex and carries ...

There is a high incidence of intracranial aneurysms of the AcomA suggesting the possibility of an anatomic risk factor. There also exists an association of termination-type aneurysms with anatomic variations of 1 anterior cerebral artery trunk (A1) as the exclusive or dominant supply to both pericallosal arteries (A2). This yields ...

Intracranial aneurysm volume and shape are important factors for predicting rupture risk, for pre-surgical planning and for follow-up studies. To obtain these parameters, manual segmentation can be employed; however, this is a tedious procedure, which is prone to inter- and intra-observer variability. Therefore there is a need for an automated ...

Catheter-based intra-arterial digital subtraction angiography (IADSA) is widely trusted for diagnosing cerebral aneurysms. However, three-dimensional CT angiography (3D-CTA) is evolving. This study compares the diagnostic performance and inter-rater reliability of 64-slice 3D-CTA and IADSA. Nineteen patients with 26 suspected cerebral aneurysms (23 with confirmed aneurysms, three negative controls) underwent both ...
