We reviewed our experience with 99 patients who had 111 femorofemoral bypass grafts placed over a 10-year period. Mean follow-up was 36 +/- 28 months (range: 1 to 120 months). Bypass alone was performed in 89 cases (group 1). Preoperative donor iliac angioplasty was utilized in 22 cases (group 2). Overall graft failure was 21 of 89 in group 1 and 2 of 22 in group 2 (difference was not significant by chi 2: p greater than 0.05). Clinical success as calculated by life-table analysis was 95%, 83%, 75%, and 67% at 1, 3, 5, and 7 years, respectively, for group 1. Clinical success was 100% and 91% at 1 and 3 years, respectively, and 91% at 42 months for group 2. The success rates were not different for the two groups when analyzed by the log-rank test at 42 months (p greater than 0.30). We conclude that donor iliac angioplasty and femorofemoral bypass is an excellent option for patients with severe occlusive disease of one iliac artery and contralateral disease amenable to angioplasty.
