Abstract
A total of 104 patients underwent surgical or endovascular surgery (percutaneous transluminal angioplasty: PTA or atherectomy: ATE) between November 1989 and May 1997. In the bypass group, early patency was 96.7%. Actuarial patency for the bypass group was 90.7% at 2 years, 88.1% at 4 years, and 83.2% at 6 years. For iliac lesions, it was 89.6% at 2 years, 85.9% at 4 and 6 years, and for femoral lesions, it was 94.1% at 2 and 4 years, and 80.1% at 6 years. In the PTA group, the early success rate was 76.2%. At 2 years, patency was 23.8%. For iliac lesions it was 30.6% at 2 years, and for femoral lesions, it was 15.6% at 2 years. In the ATE group, the early success rate was 95.0%. At 2 years, patency was 48.9% and at 4 years, it was 39.1%. For iliac lesions, it was 50.0% at 2 and 4 years, and for femoral lesions, it was 49.0% at 2 years and 36.7% at 4 years. Early patency for the bypass group was significantly better than the early success rate for the PTA group. Long term patency for the bypass group was significantly better than for other group. In early results and long term patency, there were almost no differences between the PTA group and the ATE group. In conclusion, bypass shows superior results in comparison with PTA and atherectomy in patients with chronic occlusion of the iliac and the femoral arteries.
