Indications for endovascular repair of the iliac artery are:
Stenosis or (short-segment) occlusion of iliac artery (TASC type A and B, TASC C lesions are controversial) with ipsilateral lower extremity ischemia (lifestyle-limiting, progressive claudication, rest pain, gangrene).
Patients with asymptomatic aneurysm greater than 4 cm in diameter.
An iliac aneurysm which has also increased in size by 0.5 cm in last six months.
Symptomatic iliac artery aneurysms mandate endovascular (or open) repair regardless of size.
Patients with long occluded lesions/poor run-off/acute limb ischemia are poor endovascular candidates.
