Risk Factors for Venous Thromboembolism and Eventual Amputation in Traumatic Femoral and Iliac Vein Injuries: A Trauma Quality Improvement Program Analysis.

Background: Iliac and femoral venous injuries represent a challenging dilemma in trauma surgery with mixed results. Venous restoration of outflow (via repair or bypass) has been previously identified as having higher rates of VTE (venous thromboembolism) compared to ligation. We hypothesized that rates of VTE and eventual amputation were similar whether restoration of venous outflow vs ligation was performed at initial operation.
