Percutaneous transluminal angioplasty of abdominal aortic stenoses.
Percutaneous transluminal angioplasty (PTA) was performed on 25 patients with localized distal abdominal aortic stenoses. All patients were smokers and all complained of bilateral lower limb claudication. Eleven patients had small distal aortas and iliac vessels. Technically successful dilatation was achieved in all patients. Long-term follow-up was available on 17 of the patients. The mean follow-up period was 38 months. Cumulative patency at 5 years was 70%. Thirteen patients remain asymptomatic 15-83 months following PTA. Late failure occurred in 4 patients, 1-38 months following PTA. No complications related to PTA were experienced. PTA of localized aortic stenoses is a safe alternative to surgery and should be the treatment of choice in this condition.
