Abstract: Objective To evaluate the value of bypass graft in the treatment of critical lower limb ischemia with distal single outflow artery.Methods Forty-nine lower limbs in 42 patients with single outflow artery were collected and underwent arterial bypass graft.The operation methods included femoropopliteal artificial graft to single outflow artery with autograftand popliteal artery to calf vessel and so on.The results were analyzed finally.Results All of 42 patients,postoperative grafts occlusion occured in 1 case,the occlusion rate was 2.4％(1/42) and the success rate was 97.6％(41/42),1 case died of respiratory failure 4 d postoperatively,the mortality was 2.4％(1/42).The patency rate of graft was 100.0％(41/41) on discharge.Healing rate of foot ulcer was 33.3％ (11/33).Conclusions It's difficult to reconstruct blood flow for critical ischemic limb with single outflow artery,but good result is still expected by distal lower limb bypass graft.Distal bypass can provide a better nutritional support for the healing of foot ulcer and result in a lower limb salvage or lowering of amputation level.
