The use of the Wallstent in aorto-iliac vascular disease.

Forty-three patients had self-expanding endovascular Wallstents inserted for aorto-iliac arterial disease. A total of 59 Wallstents were inserted into 50 iliac arteries. There were 27 males and 16 females with a mean age of 62.51 years. Included in the series were 19 iliac occlusions, 21 severe atheromatous disease of the aortoiliac segment, two severe dissections following conventional angioplasty and one re-stenosis of a previously dilated iliac segment. All of the stents were successfully deployed but there were five significant complications. One case of distal embolism was treated by surgical embolectomy but the other four were treated by an additional percutaneous technique. At follow-up after 6 months all patients remain symptomatically improved. Aorto-iliac stenting is a cost-effective treatment in selected cases of severe aorto-iliac disease.
