Injury to the popliteal artery.

During a 32 year period, 164 patients with 165 popliteal artery injuries were treated. One hundred twenty-five injuries were due to penetrating trauma, and 40 to blunt force. During the first decade reviewed, with ligation the main method of management, the amputation rate was 74 percent. Almost routine attempts at vascular repair over the ensuing 10 years reduced the amputation rate to 28 percent. During the final 12 years, six amputations were required for 81 injuries, thereby producing an amputation rate of only 6 percent. From this experience, the following principles of management have evolved: (1) early diagnosis is best accomplished by a careful history and detailed physical examination, not by arteriography; (2) thrombectomy followed by distal heparinization before repair is the best method for guaranteeing an adequate arterial outflow tract and thus successful revascularization; (3) resection of all injured vessels with reconstitution of continuity by the use of an interposed saphenous vein graft is often warranted to avoid tension; (4) popliteal vein repair should be performed when practical; and (5) subperiosteal fibulectomy-fasciotomy should be done routinely immediately after vascular repair.
