Angioplasty of the iliac and femoral arteries. Initial and long-term results in short stenotic lesions.
This retrospective study presents the initial and long-term results of 212 iliac and femoral angioplasties in a selected group of 175 patients with one to three short stenotic lesions (less than 3 cm each). Patients who had iliac (n = 157) and femoral (n = 55) angioplasties were followed for 6-101 months. Claudication was the principal indication for intervention. Success or failure was defined by using a combination of clinical and objective vascular laboratory criteria. Long-term success was estimated by the Kaplan-Meier method. Differences between survival curves for factors such as site of angioplasty and status of run-off were analysed with the log-rank test. For all 212 angioplasties, the initial technical success rate was 93%. The immediate failure rate was 7% (15/212). The cumulative patency rate after 5 years of all technical successful angioplasties was 82% (SE 4%). Five-year patency rates were 84% (SE 4%) for iliac and 73% (SE 11%) for femoral angioplasty. Only one variable in this selected group of patients was associated with success: the site of the lesion.
