The pregnancy outcome of women with congenital uterine anomaly exceeding 20 weeks of gestation / 대한산부인과학회지

ABSTRACT

OBJECTIVE: To evaluate the pregnancy outcomes of women with congenital uterine anomaly exceeding 20 weeks of gestation. METHODS: We reviewed retrospectively the birth records of the Seoul National University Hospital between January 1, 1990, and December 31, 2005. We grouped congenital uterine anomalies into five classes, namely bicornuate, didelphys, septate, arcuate, and unicornuate uterus. We compared the pregnancy outcomes with each anomaly. RESULTS: We found 106 cases of congenital uterine anomaly within a given period of time. There were 63 cases of bicornuate uterus, 19 cases of didelphys, 16 cases of septate uterus, 5 cases of arcuate uterus, and 3 cases of unicornuate uterus. The overall preterm delivery rate was 22.6% (24/106) and cesarean section rate was 74.5% (79/106). A high cesarean section rate was due to metroplasty, abnormal fetal presentation, and uterine anomaly itself. The preterm delivery rate and cesarean section rate of each uterine anomaly did not differ statistically from one another. Five fetuses were stillborn, and one fetus died after birth because of a placenta abruption. The overall take-home baby rate was 94.3% (100/106). There was no maternal mortality and only one case was suffered from postpartum bleeding. CONCLUSION: Our results suggest that the most of women with uterine anomaly exceeding 20 weeks of gestation may take their baby home.
