Operative Management and Outcome of Iliac Vessel Injury: A Ten-Year Experience

The purpose of this study is to review demographics and examine and stratify risk factors related to the outcome of operatively treated iliac vascular injuries. We conducted a retrospective review of 78 cases of iliac vessel injury. Patients with blunt and penetrating injury had statistically similar length of hospital stay and intensive care unit stay, incidence of shock, and mortality. Shock on admission and bleeding hematoma are linked, and shock increased mortality with an odds ratio of 5.2 (P= 0.002). A review of operative technique and outcome demonstrated a low mortality of 25 per cent in arterial bypass of an isolated arterial injury versusa mortality of 83 per cent in the combined injury group. Patients treated with primary repair of venous injuries had a lower incidence of shock and mortality compared with patients treated with venous ligation. We conclude that, if matched for severity of injury and physiologic instability, the mechanism of injury does not affect mortality. Shock is the most significant prognostic factor for mortality. Operative management must be based on presence of shock.
