[Congenital uterine anomalies in pregnancy]

From 1984 to 1989, 805 infertile women were examined hysterosalpingographically and 127 (15.8%) proved to have one of the congenital uterine anomalies. The control group consisted of 45 fertile women with the anatomically normal form of the uterine cavity as was checked by the HSG method. Out of 127 patients, 4 (3.1%) had uterus unicornis, 76 (59.8%) arcuatus, 27 (21.35%) bicornis, 19 (15.0%) septus and 1 (0.8%) didelphys. In the group of 4 cases of the unicornuate uteri, only 1 had spontaneous abortion. In the group of 76 patients with the arcuate uteri, 11 (14.5%) had one or more spontaneous abortions and 4 (5.3%) premature delivery. Out of 48 pregnancies in this group, 14 (29.2%) ended with spontaneous abortion, and out of 24 deliveries, 4 (17.4%) were premature. There was a statistically considerably higher number of spontaneous abortions than in the control group (x2 = 49.8, p = 0.05). In the group of 27 patients with the bicornuate uteri, 12 (44.4%) had spontaneous abortion and 1 (3.7%) a premature delivery. Out of 25 pregnancies, 12 (48.0%) ended with spontaneous abortion, and out of 8 deliveries, 1 ended prematurely. Evident by, there was a considerably higher number of spontaneous abortions than in the control group (x2 = 24.2 p = 0.05). In the group with the septate uteri, out of 19 patients, 12 had spontaneous abortions and 4 premature delivery. Out of 34 pregnancies, 25 (73.5%) ended with spontaneous abortion, and out of 5 deliveries, 4 ended prematurely.(ABSTRACT TRUNCATED AT 250 WORDS)
