Treatment of a persistent sciatic artery aneurysm by endovascular exclusion method through internal iliac artery closure

A persistent sciatic artery (PSA) is an extremely rare congenital vascular malformation. A 64-year-old female patient was admitted with recurrent distal embolism of the right lower limb with symptoms of ischemic vascular complications. Computed tomography and angiography revealed an entirely occluded distal PSA and an accompanying aneurysm. The PSA aneurysm was successfully treated using two self-expanding stent grafts to occlude the origin of the internal iliac artery. After arterial reconstruction, ischemic symptoms showed complete recovery.
