Revascularization of the lower extremity using the in situ saphenous vein bypass graft has resurfaced as a clinical alternative to reversal of the saphenous vein. Early patency rates have been excellent, however, concern has been raised about the durability of the in situ technique. Our total experience with this technique has been reviewed to evaluate its effectiveness on a teaching vascular service. Seventy-six limbs in 71 patients were revascularized using the in situ technique. The distal anastomosis was created at the below-the-knee popliteal level in 26 limbs and at the infrapopliteal level in 50 limbs. Operative assessment of the vein quality showed 42 percent to be phlebitic or less than 4 mm in diameter. Hospital mortality was 0 and late mortality was 8 percent. Cumulative life table analysis showed the graft patency rate to be 89 percent 1 month postoperatively, 82 percent at 1 year, 77 percent at 2 years, and 72 percent up to 4 year postoperatively. Patency was independent of runoff to the pedal arch and the level of the distal anastomosis. Limb salvage at 4 years was 83 percent for distal popliteal grafts and 79 percent for infrapopliteal reconstructions. Our results indicate that the long-term durability of the in situ saphenous vein graft is excellent despite suboptimal veins and poor runoff. When performed properly, it is the preferred technique for arterial reconstruction below the knee joint. |
