Endovascular Revascularization of Diseased Native Arteries following Failed Aortoiliac and Femoropoliteal Grafts: Report of Two Cases

Arterial reconstructions for lower-extremity ischemia, comprising aortoiliac, aortofemoral, and femoropopoliteal bypasses, and other procedures, have an intrinsic tendency to fail as time elapses. Surgical approaches to arteries in patients who have failed bypass grafts are often rendered more difficult, or even impossible to use, by surgical scarring or infection. The authors report two cases in which the diseased native arteries treated with failed aortoiliac and femoropopliteal bypass grafts were successfully recanalized with primary stent placement. Our cases show that stent placement of the diseased native arteries can represent a possible option for the treatment of failed bypass grafts.
