Fracture of a popliteal nitinol stent and pseudoaneurysm: a case report and review of the literature

Abstract There is a lack of reports onr stent fracture with pseudoaneurysm formation in the femoropopliteal artery, which can cause restenosis or occlusion of the treated arterial segment. We present a case of a large pseudoaneurysm of the popliteal artery that was observed 18 months after popliteal stenting using a self-expandable nitinol stent. We describe an endovascular approach to overcome this severe complication. Stent fractures are an often overlooked complication of femoropopliteal stenting and can be associated with serious diseases. The popliteal artery was successfully treated using self-expandable Viabahn endoprosthesis.
