The persistent sciatic artery aneurysm a cause of recurrent limb ischemia – A rare case report

Abstract

A persistent sciatic artery (PSA) is a rare vascular anomaly. It can cause complications, including acute and chronic limb ischemia, aneurysm formation, and compression of adjacent tissues during early embryonic development, the sciatic artery usually disappears when the superficial femoral artery has developed properly. PSA is usually an incidental finding and is exceedingly rare to find bilaterally. We are presenting a rare case of unilateral PSA aneurysm presented as an episode of recurrent acutely ischemic limb.
