Abstract
The results of 65 unilateral grafts were compared with those of 96 bifurcation grafts in the treatment of aortoiliac occlusive disease. Although the operative mortality was similar in both groups, the five-year patency rate of the unilateral grafts (52.1%) was markedly less than that seen in the bifurcation grafts (78.3%). Further surgery on the contralateral, aortoiliac system was required in 16.9% of patients who received unilateral grafts.
