Out of 180 patients who had a myomectomy at the Chelsea Hospital for Women between 1954 and 1962, 116 were followed for more than one year. One in four of these patients had a subsequent hysterectomy and about one in three conceived after surgery. Of the patients known to have conceived only three out of four carried pregnancies beyond 28 weeks. Myomectomy did not seem to alter the high incidence of abortions and perinatal deaths in patients found to have fibromyomata. Pregnancies occurring after myomectomy required close specialist supervision and often ended in Caesarean section.
