Short-term and midterm results of an all-autogenous tissue policy for infrainguinal reconstruction.

Abstract

Saphenous vein is the optimal conduit for infrainguinal vascular reconstruction. In instances in which this vein is unavailable or of "poor quality," reliance has been placed on a variety of prosthetic materials for bypass grafting. However, long-term patency with these prosthetic grafts has been disappointing. In January 1985 we instituted a policy of using exclusively autogenous tissue for infrainguinal arterial reconstruction. During the ensuing 3-year period, 203 patients underwent 266 arterial operations below the inguinal ligament, with a prosthetic graft used in only 11 instances (4%). No patient was denied surgery for limb salvage because of a lack of available autogenous vein. Thirty-three percent of procedures were performed for failure of prior revascularization and 73% for limb salvage. The 3-year cumulative primary patency rate for all autogenous procedures was 72%. Procedures were divided into those that used greater saphenous vein (patency 77%) vs autogenous alternatives such as bypass with arm vein or lesser saphenous vein, vein patch angioplasty, and endarterectomy (patency 64%). The operative mortality rate was 1.4% and the 3-year limb salvage rate was 89%. Autogenous infrainguinal reconstruction can be performed in almost every instance with acceptable results, suggesting that the need for prosthetic bypass grafts in the lower extremity is less than has been previously reported.
