[Significance of myoma-induced complications in pregnancy. A comparative analysis of pregnancy course with and without myoma involvement].

In the present study we analyzed the relation between complications in pregnancy--fetal growth retardation, premature rupture of membranes, preterm labour, abruptio placentae, mode of delivery, puerperium--and the size, number and location of myomas. A retrospective comparison was performed in 474 patients (94 pregnant women with myoma and 380 with a normal uterus as controls). The course of pregnancy, the mode of delivery and the puerperium were examined. The study showed that retroplacental submucous myomas increase the risk of fetal growth retardation (14% vs. 6.6%) and abruptio placentae (3.2% vs. 1.3%). The size of the myomas was not relevant. A caesarean section, especially for fetal malpresentation, was also more frequent in patients with submucous myoma (52.9% vs. 27.9%). There was no difference, however, in the postpartal course between the submucous myoma group and the controls, respectively. Subserous or intramural fibroids had no influence on the course of pregnancy, the mode of delivery or the postpartal period.
