Abstract:

Didelphic uterus are caused by Müllerian tube fusion failure that eventually form two uterine cavities, which is one of the rarest uterine malformations. Women with Müllerian anomalies may increase the incidence of perinatal complications and adverse outcomes of pregnancy. If Müllerian anomalies are found during pregnancy, the type of abnormality should be identified promptly, the impact on the mother and fetus should be assessed, and the frequency of prenatal care should be appropriately increased. Ovarian pregnancy as a rare ectopic gestation is often difficult to diagnose before surgery. Ovarian pregnancy seemingly has no logical relationship with the didelphic uterus. The high risk factors of ovarian pregnancy may include intrauterine device, assisted reproductive technology (ART) and intrauterine surgery history. A case of ovarian pregnancy in a woman with didelphic uterus after ART was reviewed, and the possible causes of ovarian pregnancy were summarized and analyzed. Single embryo transfer should be considered as the best transplantation strategy for those patients with didelphic uterus. Women of childbearing age should undergo a thorough pelvic examination before ART in order to make early diagnosis and proper management of congenital uterine abnormalities.
