Estrogens and postoperative thrombosis evaluated by the radioactive iodine method.
Women who were to be operated upon for prolapse of the uterus were treated preoperatively with estrogens for atrophic vaginal mucosa and examined postoperatively by the 125I-fibrinogen uptake test and phlebography. Among 11 women who received 50 micrograms of ethinyl estradiol daily for three weeks, fibrin deposits were found in six. Of eight women receiving 200 micrograms daily for 12 days, such deposits developed in four. Corresponding figures for the control group were 18 of 157, p < 0.001. Estrogens, therefore, should not be given preoperatively, and those patients treated with preparations containing estrogens should have such therapy discontinued preoperatively.
