Infrarenal aortic stents: initial clinical experience and angiographic follow-up.

From March 1990 to May 1991, arterial stents were placed in seven patients because of a tight stenosis (five patients) or a total chronic occlusion (two patients) located in the infrarenal aorta. In one case, the aortic occlusion extended to both common iliac arteries. After balloon dilatation, aortic stents were successfully positioned in all cases. Bilateral common iliac recanalization and stent placement were performed in one case. No complications occurred in any of the patients. No complications occurred in any of the patients. Follow-up data were derived from clinical assessments and angiographic results. After a 15.1-month mean follow-up period (range 12-24 months), the seven aortic stents remained patent. Three iliac artery procedures were performed in two of the patients as well. Claudication recurred in three of the seven patients which was related to a common iliac occlusion (one case) or distal progression of atherosclerosis (two cases). Aortic stents seem to be suitable for treating failed angioplasty of aortic lesions but the procedure remains technically difficult when there is associated severe atherosclerosis of the proximal common iliac arteries. Nevertheless, considering the morbidity rate (0%) and the patency rate in this series, this technique could become an alternative to surgical treatment for infrarenal aortic occlusive lesions.
