Abstract
This study reviews the recent experience with popliteal artery injuries at the Massachusetts General Hospital. Twenty-two patients suffered 24 injuries. The overall limb salvage was 83%. Blunt trauma accounted for 19 of the cases and was associated with femur fractures, knee dislocations, and tibia-fibular and plateau fractures: four amputations (21%) resulted. There were five penetrating injuries from three gunshot wounds, one stab wound, and one laceration: no amputations occurred. The major factor in the amputated limbs was delay in diagnosis and therapy of the arterial injury associated with blunt trauma. Arterial disruption secondary to penetrating injuries was recognized more quickly and had a better outcome. A higher index of suspicion in blunt trauma may improve results. Recommendations for therapy are: arterial reconstruction should generally precede orthopedic operation. Venous ligation was not associated with increased limb loss, but we recommend repair if possible. Arterial repair includes thrombo-embolectomy in distal arteries. If necessary, reverse saphenous vein is grafted. When operation is unsuccessful, revision should be performed.
