[Conservative procedures in 64 pregnant patients with myoma: the course of pregnancy, labor, and the puerperium].

During this period, the number of deliveries was 28235. Our results contradict the wide spread opinion concerning the high risk of a pregnancy in a myomatose uterus. In two thirds of the cases, the pregnancies showed a normal course, this applying also to myoma nodes of 8 cm or more dimater. Threat of premature delivery was ovserved in 11 cases; in two cases premature delivery did occur. More than nine out of ten pregnancies reached the 38th week of gestation. Spontaneous delivery was twice as frequent as Caesarean section. This, however, does not apply to myoma nodes with diameters of 8 cm or more, in which case the frequency of Caesarean section represented 50%. Puerperium was normal in 47 cases; complications were observed in 13 cases due to retarded uterine retraction. In 2 out of 4 cases with atonic post-partum haemorrhage, curettage was performed. Pregnancies in a myomatose uterus are high-risk pregnancies which require close observation. Sonography plays an important role in such cases. One of the authors (D.) proposes high-dose gestagen treatment as a useful therapy when threat of abortion is observed in myomatose uteri. In cases of menacing premature delivery, hospitalisation and tocolysis are highly recommended.
