PREDICTORS OF AMPUTATION FOR POPLITEAL ARTERY INJURIES

BACKGROUND: Popliteal artery injuries continue to result in limb loss. This study identifies risk factors that predict amputation. METHODS: Over a 5-year period, a retrospective chart review was conducted of 80 consecutive patients with 81 popliteal artery injuries. RESULTS: The overall amputation rate was 15.5%. Blunt trauma carried a higher rate of amputation (47%) then penetrating injuries (6.2%); P <0.0001). Asso ciated fractures had a higher amputation rate, regardless of mechanism (odds ratio +2.7, 95% confidence limits 1.2 to 6.2). Fasciotomy at th e time of operation was associated with reduced amputation rate. CONCL USIONS: Blunt injuries and associated fractures carry an increased ris k for amputation. Compartmental pressures should be appropriately moni tored postoperatively. Fasciotomy at the time of vascular repair may b e considered even without evidence of compartment syndrome.
