Total endovascular repair for a persistent sciatic artery aneurysm with widespread limb-threatening arterial occlusion

Abstract

In the present report, we have described the case of a 79-year-old woman who presented with acute right lower limb ischemia and was diagnosed with bilateral persistent sciatic arteries and a right persistent sciatic artery aneurysm. Concomitant widespread thrombotic occlusion was present, extending from the orifice of the right internal and external iliac arteries to the below-the-knee popliteal artery. These complicated lesions were successfully treated using only percutaneous endovascular procedures, including stent-graft placement, bare metal stent implantation, and thrombolysis. Our report illustrates how a combination of techniques can achieve total endovascular repair of a persistent sciatic artery aneurysm accompanied by occlusion of the internal and external iliac arteries.
