title: A ruptured aneurysm in persistent sciatic artery: a case report.
abstract: Persistent sciatic artery (PSA) is a rare congenital anomaly, but in many cases it is a clinically important condition. PSA is susceptible to atherosclerotic degeneration, resulting in aneurysmal dilatation, occlusive thrombosis, or thromboembolization. PSA aneurysm is associated with distal embolization, sciatic neuropathy, or rupture. We describe a case of a patient with a ruptured PSA aneurysm treated by exclusion of the aneurysm and bypass between the common iliac artery and the PSA distal to the aneurysm, and discuss treatment of PSA aneurysm.
