Peripheral vascular disease of the lower extremities is an important cause of morbidity that affects up to 10 million people in the US. More than 70 percent of patients remain stable or improve with conservative management. Those who do not may undergo contrast, CT, or MR angiography, which may be used in planning for surgery or percutaneous intervention (angioplasty).
Intermittent claudication (leg pain or discomfort while walking that abates during rest) is the most common symptom. Other symptoms include numbness or weakness in the legs, aching pain in the feet or toes while at rest, nonhealing ulcers on the leg or foot, cold legs or feet, and skin color changes.
The iliac arteries are technically among the easiest vessels to approach percutaneously. The technical success of stent placement in aortoiliac occlusive disease is 96 percent with five-year patency rates of 86 percent approaching that of surgical bypass.
