• Analysis of the immediate and long-term results in 180 patients undergoing bilateral aortofemoral bypass grafts for occlusive disease of the lower extremities showed the immediate graft limb patency in 360 graft limbs to be 99.2%. The cumulative ten-year graft limb patency was 66%. Factors associated with thrombosis of the graft limb revealed correlations for localized atherosclerotic disease of either the profunda femoris artery or the tibial trifurcation vessels. The highest correlation for graft limb thrombosis was with simultaneous lesions involving both the profunda femoris artery and tibial trifurcation vessels. The acute lower extremity salvage rate was 94%, and the ten-year cumulative extremity salvage for legs at risk of amputation was 85%. Postoperative symptoms correlated well with patency. Overall operative mortality was five patients out of 180 (2.5%).
