Blue toe syndrome commonly occurs as a result of aneurysmal or atherosclerotic disease in the iliac arteries. Surgery, angioplasty, or intraarterial stent placement are the most common treatment options but the optimal management has not been defined. Here we report managing distal microembolization from iliac artery atherosclerosis associated with aneurysmal dilation with the Wallgraft Endoprosthesis, a self-expanding metallic stent covered with Dacron. Three common iliac arteries in two patients were treated using this device. A 79-year-old male presented with unilateral symptoms and an 83-year-old female with bilateral disease. Arteriography demonstrated complex plaque at the aortic bifurcation associated with aneurysmal dilation of the distal common iliac artery in both patients. This complex disease was successfully covered using the Wallgraft Endoprosthesis. Postoperatively the patients received aspirin, their toe lesions healed, and neither has had a recurrence after 16 months. Covered stents offer the theoretic advantage of completely excluding the diseased segment, preventing the escape of thrombus or plaque debris, and covering aneurysmal dilation in the artery.
