Advances in the management of acute popliteal vascular blunt injuries

This report evaluates critical points in the management of 30 consecutive blunt traumatic popliteal vascular injuries. All arterial injuries were diagnosed both clinically and by Doppler and PVR examinations. Twenty-eight of the 30 arterial reconstructions required interposition bypass grafts, nine of which were PTFE and the remainder were autogenous saphenous veins. In 19 patients the distal anastomosis was made to the distal popliteal artery and in nine patients to the tibial-peroneal arteries. In ten patients in whom limb survival was threatened, the ischemic time was shortened by the use of temporary Silastic shunt for rapid restoration of arterial flow. Nine patients had associated venous injuries which were repaired. Nine of the first 14 patients required fasciotomy but the last 16 patients were treated with hypertonic mannitol and only two of them required fasciotomy. There were no amputations, but in four limbs there were functional losses. In spite of the more extensive damage of blunt trauma, prompt and aggressive management aided by vascular laboratory tests, indwelling shunt, and hypertonic mannitol is rewarded with preservation of limbs following acute popliteal vascular injuries.
