OBJECTIVE: To evaluate the rate of salvage of lower limb with long-time injury of popliteal artery. METHODS: Twenty-one patients with injury of popliteal artery were treated. The interval between injury and repair of artery ranged from 12 hrs to 48 hrs. The essences of operation were thorough debridement of the ischemic and necrotic muscles, primary suture of wound, and repair of popliteal artery on the basis of reduction and fixation of fracture. RESULTS: The limb salvage were achieved in 19 cases. The saved limbs could fulfill the basic function of walk. CONCLUSION: Thorough debridement of ischemic and necrotic muscle and primary suture of wound were reasonable methods which could treat long-time injury of popliteal artery without amputation.
