Traumatic inferior vena caval injuries.

Abstract

Twenty-three cases of inferior vena caval injury (1.4% of all operatively managed abdominal injuries) are reviewed. The caval injury presented as free haemorrhage in 15 cases and as a retroperitoneal haematoma in eight. The site of vena caval injury was at or above the level of the renal veins in 14 cases (61%). Successful lateral suture repair was achieved in 18 cases (78%). The overall mortality rate was 39%. Factors positively associated with survival were stab wound, presentation as retroperitoneal haematoma, infrarenal injury, low Abdominal Trauma Index score and small peroperative blood loss. Concomitant injury to the abdominal aorta, liver or kidney worsened the prognosis. The crucial factor in management of inferior vena caval injuries is rapid and effective control of bleeding, whether from the caval or associated injuries.
