Axillounifemoral and Axillobifemoral Bypasses. Retrospective Study of 85 Cases

peer reviewedFrom 1983 to 1990, 65 axillobifemoral and 20 axillofemoral bypasses have been performed in 85 patients (77 men and 8 women), with a mean age of 69 +/- 9 years. Indications for surgery were: severe aortoiliac occlusive disease (87%), sepsis of previous aortoiliac prosthesis, abdominal aorta aneurysm. Anatomic bypass was precluded for general (81%) or local (19%) conditions. In the last group, 9 patients have had previous laparotomy. Four patients presented with aortoenteric fistulas. Eighteen patients were operated on in emergency. The operative mortality was 12%, with 50% cardiac related deaths. Early primary patency was 98%. Early secondary patency was 100%. The mean follow-up is 28 +/- 15 months. The 3 years survival is 77%. The cumulative patency rates at 1 and 3 years are 89% and 76% respectively. Although axillobifemoral bypasses achieve poor long-term results when compared with aortoiliac bypasses, they can be considered in high risk patients. In this group of patients, the cumulative patency rate and the survival curves tend to be parallel
