Abstract
During a 1-year period, three patients presented with acute traumatic thrombosis of the common or external iliac artery concomitant with a massive crush injury to the pelvis. All had vascular compromise of the involved extremity on initial physical examination, but in two patients with open pelvic trauma, exsanguination, major visceral injury, hypothermia, and a coagulopathy precluded emergency vascular reconstruction. Both required hindquarter amputation for adequate debridement. The third patient presented without exsanguination or visceral trauma. Angiography and vascular reconstruction were undertaken, but myonecrosis compounded the initial vascular compromise, and eventually required a hip disarticulation for debridement. It was concluded that: exsanguination and/or major visceral injury takes priority over emergency vascular reconstruction; soft-tissue injury may preclude limb salvage despite vascular reconstruction. If a cadaveric limb exists, early radical amputation, including hindquarter amputation, should be undertaken.
