Iliofemoral bypass surgery for lower limb ischaemia. A follow-up of 62 patients.

This study evaluates iliofemoral bypass reconstruction in limb-salvage, graft patency, and appearance of contralateral symptoms. The study included 62 consecutive iliofemoral bypass reconstructions during 1980-82. The indication for surgery was disabling intermittent claudication in 19% of the patients and severe ischaemia in 81%. At follow-up 42 patients were examined, 16 were dead and 4 were lost to follow-up. The primary mortality was 5%. At 3 years postoperatively the survival rate was 78%, ipsilateral limb-salvage 88%, graft patency 83%, and patency of the contralateral iliofemoral segment 92%. During the follow-up period reconstructive vascular surgery on the contralateral aortoiliac segment was performed in only 3 patients. The results of the iliofemoral bypass reconstruction in this study were comparable to the results of aortic bifurcation grafts, and the patency of the contralateral iliofemoral segment was higher than might have been expected. The iliofemoral bypass reconstruction seems to be useful for patients with unilateral affection of the iliofemoral segment, for limb-salvage concerning patients in poor general condition, and for patients who have had a contralateral amputation.
