A persistent sciatic artery aneurysm with an associated internal iliac artery aneurysm.

Introduction operation. Firstly, in the supine position, an oblique lower abdominal incision was made and the left inThe sciatic artery is the axial artery of the lower limb, ternal iliac artery identified via an extraperitoneal approach. The artery was found to be aneurysmal forming the dominant blood supply to the leg during early embryonic development. It normally involutes with a diameter of 1.5 cm. Both it and its branches were ligated proximally. A femoropopliteal bypass leaving only remnants in the mature arterial system. For it to remain in its entirety is rare. Known as a was then performed using a 6 mm Dacron graft, as no suitable vein was available. Secondly, in the right persistent sciatic artery (PSA), it is particularly susceptible to aneurysm formation. We report only the lateral decubitus position, an incision was made over the course of the aneurysm and the PSA exposed via second case of a PSA associated with an internal iliac artery aneurysm. a transgluteal approach. The artery was ligated distally and the aneurysmal sac opened. Two further feeder vessels were identified and oversewn from within the sac. The patient made an uncomplicated recovery. Case Report
