Is long vein bypass from groin to ankle a durable procedure? An analysis of a ten-year experience.
Long vein bypass from the femoral artery to the level of the ankle may be performed with good initial success despite extreme bypass length and limited outflow tracts. However, the long-term performance of these bypasses remains to be defined. During the last 10 years we have performed single greater saphenous vein in situ bypass to the ankle level in 270 patients. There were 187 male and 83 female patients, and 61% of the patients were diabetic. The operative mortality rate was 3.7%. Cumulative bypass patency was 79% at 3 years and 73% at 5 years. In a similar manner, limb salvage was 93% at 3 years and 89% at 5 years. The patency rate was similar for various inflow arteries (common femoral, 88 cases; proximal superficial femoral, 135 cases; and deep femoral, 41 cases) and outflow tracts (dorsal pedal, 72 cases; anterior tibial, 59 cases; posterior tibial, 72 cases, and peroneal, 67 cases). Short bypasses, composite bypasses, free-vein grafts, and bypasses proximal to 10 cm above the ankle were excluded from this analysis. These data show that a long bypass to the ankle level for limb salvage is a durable procedure. The basic concept of bypassing all occlusive disease to the distal open artery in patients undergoing limb salvage should be an acceptable dictum. Excellent long-term patency and limb salvage rates are achievable by following this principle.
