To further evaluate the efficacy of in situ saphenous vein bypass, the authors have reviewed their experience with in situ bypass. Between October 1981 and December 1985, 120 in situ saphenous vein bypass were performed; 81 were to infrapopliteal vessels. All procedures were performed for limb salvage. The mean patient age was 74 years, and 74% were men, 57% had diabetes mellitus, 92% were smokers, and 72% had hypertension and/or coronary artery disease. All patients were evaluated by preoperative noninvasive testing and biplanar angiography. All procedures were performed by the valve incision technique. The vein utilization rate was 91%. Grafts were routinely placed into isolated tibial segments and foot vessels without evidence of a patent pedal arch. Follow-up information was obtained at 3-month intervals. Patency and limb salvage data were calculated by life-table analysis. The cumulative patency rates were 98% at 1 month, 88% at 12 months, and 82% at 50 months. These data demonstrate that the in situ bypass maintains an excellent patency rate and provides durable limb salvage.
