[Prophylaxis of thromboembolic complications in gynecological surgery (author's transl)].

Eight prospective, controlled, randomised studies on the incidence of postoperative thrombosis in gynaecological patients receiving various drugs for prevention of thromboembolism are analysed. In all patients diagnosis had been established by objective means. The rate of thrombosis in patients without drug prophylaxis has been found to vary between 14 and 29%. Infusions of dextran as well as administration of low-dose subcutaneous heparin significantly reduce the incidence of deep vein thrombosis, even as compared to postoperative oral anticoagulation with cumarins. No difference has been found between dextran and oral anticoagulants, when cumarin adminstration was started before operation, nor between dextran and heparin. Aescin did not show any prophylactic effect. High age, severe leg-vein varicosis as well as surgery for malignant disease increase the risk of thrombosis. No significant influence of overweight, previous deep venous thrombosis, epidural anaesthesia or vaginal operation as compared to abdominal approach could be demonstrated. There are no properly controlled, prospective, randomised studies on the incidence of postoperative fatal pulmonary embolism as influenced by drugs in gynaecological surgery.
