[Early detection of postoperative deep-vein thrombosis in gynaecological patients by the 125I-Fibrinogen test (author's transl)].

Deep-vein thrombosis was detected by means of the 125I-fibrinogen test in 37.2% of patients undergoing gynaecological surgical procedures within the first six days postoperatively; 50% of the cases occurred within the first 48 hours. There was no difference in the incidence of thrombosis according to whether the abdominal or vaginal approach had been used. Varicose veins proved to be a high-risk factor in the development of deep-vein thrombosis. Prophylactic administration of horse-chestnut extract has to begin preoperatively in order to achieve a beneficial result.
