Abstract

<p>Persistent sciatic artery is a rare congenital vascular anomaly but could be associated with leg ischemia due to aneurysmal degeneration. An 84-year-old woman presented right leg pain and CT showed a right persistent sciatic artery aneurysm with an intramural thrombosis and occlusion of the distal popliteal artery. Initial thrombolytic therapy was effective but right leg pain recurred and amputation of toes were performed for ulcer formation. To prevent recurrence of thromboembolism, resection of the aneurysm was successfully performed through buttock approach after femoro-popliteal bypass.</p>
