Prophylactic interruption of the inferior vena cava. A retrospective evaluation.
One hundred sixty patients were retrospectively evaluated to determine the effect of prophylactic inferior vena caval interruption in association with aortic surgery. Sixty-three patients underwent aortic procedures without inferior vena caval interruption and ninety-seven patients underwent placement of an Adams-DeWeese clip as prophylaxis against pulmonary embolism. Pulmonary embolism occurred in 10 per cent of the group without the clip and in no patients in the group with the clip. The incidence of deep vein thrombosis was identical in both groups (10 per cent). The 6 per cent rate of early (within 6 months) postoperative leg edema in the group with the inferior vena caval clip was a significant problem in only one patient after twenty-four months. Prophylactic interruption of the inferior vena cava has been shown to be a safe method of decreasing the incidence of pulmonary embolism without increasing the incidence of venous-related complications.
