Abstract: We report on a series of 930 patients who received an aortobifemoral Dacron graft between 1963 and 1988. The operative mortality was 5.6% and the mean follow-up reached 5.45 years (range one month to 23.6 years). Late occlusion was noted in 125 patients and the primary patency rate decreased to 74% and 69%, respectively at 10 and 15 years. Long-term patency was primarily (p less than 0.05) dependent on (1) the date of operation, (2) postoperative smoking habits, (3) distal occlusive disease, and (4) age of the patients at the time of surgery. Vascular reconstruction for late thrombosis was performed for 110 late occlusions in 103 patients. Included were 95 unilateral and 15 bilateral occlusions. The method of choice was graft limb thrombectomy (unilateral occlusion) or anatomical graft replacement (bilateral occlusion or unilateral occlusion when thrombectomy proved to be impossible). Associated outflow reconstructions consisted of profundaplasty in 73.3% of the cases. A mean yearly thrombosis rate of 9.4% (range 4-14%) resulted in a five year patency rate of 59%. Differences between graft thrombectomy and anatomical replacement were not statistically significant. Reconstruction for secondary occlusions was associated with a 25% thrombosis rate. Tertiary occlusion in six cases invariably led to major amputation. A total of 20 patients ultimately needed a major amputation, resulting in an eight year limb salvage rate of 79%.
