Perioperative external pneumatic calf compression as thromboembolism prophylaxis in gynecologic oncology: Report of a randomized controlled trial

Postoperative venous thromboembolic complications are a major problem for the gynecologic oncologist. External pneumatic calf compression (EPC), when applied intraoperatively and left on the patient's legs for 5 days postoperatively, has been previously demonstrated to significantly reduce the incidence of venous thromboembolic complications in patients undergoing surgery for pelvic malignancies. The purpose of this study is to evaluate whether a short perioperative course of EPC is also effective in preventing venous thromboembolic complications. One hundred ninety-four patients participated in a randomized controlled trial of perioperative external pneumatic calf compression. 125I-labeled fibrinogen scanning and impedance plethysmography were used as prospective surveillance methods in both groups. Venous thromboembolic complications were diagnosed in 12.4% of control group patients and in 18.6% of EPC group patients. External pneumatic calf compression when used only in the perioperative period appears to be of no benefit in reducing the incidence of postoperative venous thromboembolic complications.
