The current role for femorofemoral bypass.

We reviewed our experience with femorofemoral bypass during the past 10 years to define its role relative to other methods in the treatment of aortoiliac occlusive disease. The cumulative patency rate for 82 patients was 80% +/- 5% at 1 year and 67% +/- 7% at 2 and 3 years. The operation was most likely to be successful if the indication was claudication (p less than 0.05) and if the operation was performed as the primary procedure (p less than 0.01). There was no significant difference when patients with or without profundaplasty were compared. It is concluded that femorofemoral bypass is indicated to treat symptomatic unilateral iliac disease when transluminal dilatation is not possible. Femorofemoral bypass is also the procedure of choice for aortofemoral graft occlusion when the thrombosed limb cannot be reopened. Femorofemoral bypass is recommended for both high- and low-risk patients when indicated.
