Vascular trauma in the groin: contrast between iliac and femoral injuries.

Vascular injuries to the groin are common and often life-threatening. Injuries above the inguinal ligament, to the iliac system, are associated with a 37 percent mortality. Associated intraabdominal injuries are common. These patients must be identified promptly, given broad-spectrum antibiotics and taken immediately to the operating room for exploration through a midline incision. Injuries below the inguinal ligament are usually to the femoral vessels and are rarely fatal. These patients may be evaluated more extensively before leg exploration. Associated intraabdominal injuries are unusual, but disability from femoral fractures and nerve injuries are common.
