Injuries of the inferior vena cava.

ABSTRACT

The treatment of 77 patients with wounds of the inferior vena cava admitted to Grady Hospital, Atlanta, Georgia, from January 1972 through December 1983, was reviewed. All injuries were identified by laporotomy and/or thoracotomy. Trauma resulted from gunshot wounds in 79 per cent of patients, stab wounds in 18 per cent, and blunt trauma in 3 per cent, with an overall mortality of 30 per cent. The chief determinates of survival were preoperative hypotension, location of the injury and the presence of other major vascular injuries. Of the 49 patients admitted in shock, 22 (45%) died, all of complications related to organ ischemia. Only one patient not hypotensive on admission succumbed. Of the 29 patients with at least one additional injury to a major vascular structure, 45 per cent died. The mortality of infrarenal and suprarenal injuries was relatively low (22% and 33% respectively), compared with retrohepatic and supradiaphragmatic injuries, both of which were fatal in 67 per cent of the cases. Despite advances in the care of the trauma patient, significant improvement in survival has not occurred, and the patient mortality has remained at 30 per cent.
