Ballistic arterial trauma to the lower extremity: recent South African experience.

The aim of this study was to determine the current outcome of gunshots to the arteries of the lower extremity. The authors conducted a retrospective analysis of 104 patients with gunshots to the femoral (n=71) and popliteal (n=33) artery. One hundred four patients presented over the 60-month period. Ninety-six (92%) were male and eight of 104 female. Ninety-nine were gunshot injuries, five from shotguns. Nine patients had injury to the common femoral artery, 62 patients had injury to the superficial femoral artery, and 33 had popliteal artery injury. One patient died in the emergency room and another died in the postoperative period, giving an overall in-hospital mortality of two of 104 (1.9%). Forty-three of 70 femoral reconstructions had completion angiograms compared with 20 of 32 popliteal artery reconstructions (P=1). Nineteen of 63 (30%) of the completion angiograms prompted revision of the reconstruction. Of the 63 patients who had completion angiograms, two of 63 (3%) required amputation. Seven of 39 (18%) patients who did not have completion angiograms required amputation (P = 0.025). Including the primary amputation, there were 10 amputations in the 103 patients (9.7%) who survived to undergo operation. Ballistic arterial trauma of the lower limb leads to significant disability. Completion arteriography leads to revision of the reconstruction in nearly one-third of instances and significantly reduces amputation rate.
