Occluded persistent sciatic artery.
The case of a patient with ischemic symptoms due to occlusion of a persistent left sciatic artery is presented. Femoral arteriography revealed a tapering hypoplastic superficial femoral artery terminating as small branches in the distal thigh and a hyperplastic profunda femoris artery. Also, translumbar aortography demonstrated an abrupt occlusion of a hyperplastic left hypogastric artery just distal to the inferior gluteal artery. The popliteal artery was found to be patent and perfused by collaterals. A bypass graft using a composite E-PTFE prosthesis and an autogenous vein graft was successfully performed.
