Venous thromboembolism prophylaxis in gynecologic oncology: a prospective, controlled trial of low-dose heparin
Abstract:
One hundred eighty-five patients undergoing operation for gynecologic malignancy participated in a randomized controlled trial of low-dose heparin prophylaxis. Prospective surveillance for deep venous thrombosis was performed with daily fibrinogen 125I counting in the legs and impedance plethysmography. Twelve of 97 (12.4%) patients in the control group and 13 of 88 (14.8%) patients in the low-dose heparin group developed a venous thromboembolic complication. There was no statistical difference in the incidence of proximal deep vein thrombosis, calf vein thrombosis, or pulmonary emboli between the control and low-dose heparin groups. Low-dose heparin does not afford any prophylactic benefit to patients undergoing major pelvic operative procedures for gynecologic malignancy.
