Birth Outcomes in Pregnancies with Uterine Malformations: A Single-Center Retrospective Study

Abstract

Background and objectives: The prevalence of uterine malformations, affecting up to 7% of the general population, is associated with high rates of pregnancy complications, such as infertility, miscarriage, preterm delivery, malpresentation, ectopic pregnancy, and other complications, with high rates of both maternal and fetal morbidity and mortality. Surgical procedures have been proposed to remediate these anomalies, with different outcomes. In this context, our study aimed to emphasize the complications encountered in our department and the pregnancy results. Materials and Methods: A retrospective cohort study was performed on all the women who delivered in one university-affiliated medical center between 2010 and 2017 with congenital uterine malformations. A total of 62 women were included: 26 with uterine malformations and 36 as controls. Statistical analyses were performed with the level of statistical significance set at p < 0.05. Results: Only 53.8% of the pregnancies in women with uterine malformations ended in a live birth. The cesarean section rate was 64.3% in the study group. The only successful surgical procedure performed to restore fertility was cerclage. A lower Apgar score and a higher rate of neonate admission into the intensive care unit were observed in the study group, at 11.5% compared to 0 in the control group. The most important complication encountered with statistical significance was preterm delivery. Conclusions: This study demonstrated that uterine congenital malformations are an independent risk factor for pregnancy complications.
