Intraoperative external pneumatic calf compression to afford long-term prophylaxis against deep vein thrombosis in urological patients.

In a prospective randomized study of patients undergoing open urological operations, we found external pneumatic compression (EPC) of the calves applied in the operating room and recovery room as effective in reducing deep vein thrombosis as EPC continued during convalescence until resumption of ambulation. Provided early postoperative ambulation is practiced, intraoperative EPC appears to be adequate prophylaxis and equivalent to long-term EPC for prevention of deep venous thrombosis in urological patients.
