Endovascular repair of bilateral sciatic artery aneurysm with Covera® self expandable covered stents - case report

Abstract

A persistent sciatic artery is an embryological remnant of the internal iliac artery that occurs in 0.03% to 0.06% of the population and may develop aneurysmal degeneration. Aneurysms can lead to distal embolization with increased risk of limb loss, especially if the sciatic artery is the main arterial supply to the limb. A sciatic artery aneurysm must be treated whenever diagnosed, because of the high risk of complications. Treatment options include open, endovascular, or hybrid repair. This manuscript describes a patient with bilateral persistence of the sciatic arteries, both with aneurysmal degeneration, who underwent endovascular repair with Covera^® (Bard Medical, Georgia-USA) covered stents.
