Uterine didelphys: A Case report of successful term pregnancies in each endometrial cavity

Abstract

Background: Uterine didelphys is a rare congenital anomaly that may increase the risk of pregnancy loss and adverse perinatal outcome. There is limited knowledge of specific increased risk related to uterine didelphys. Uterine didelphys occurs in approximately 1 in 3000 women and accounts for 8 -10% of all mullerian duct anomalies (MDAs). Aim: To present this rare congenital clinical condition and offer management modality experience from the Rivers State University Teaching Hospital (RSUTH). Case report: Mrs. MC was a 33 year old booked G3 Para 1+ 1 (alive), previous caesarean section, who presented for antenatal care. Her index pregnancy was complicated by premature uterine contractions and ante – partum haemorrhage at 29 weeks and 30 weeks gestation respectively which were managed successfully. Obstetric ultrasound scan revealed a second uterine cavity with separate endometrial plate in keeping with uterine didelphys. She subsequently had an elective repeat caesarean section at 38 weeks gestation for transverse lie and uterine anomaly. Findings were a gravid left uterus and an empty right uterus with a lower segment scar. The left uterus contained a live male neonate in transverse lie with a birth weight of 3.5 kg and good Apgar scores. The baby was successfully managed for neonatal Jaundice. The mother developed postpartum haemorrhage which was successfully managed. The mother and baby were discharged on the 5th and 12th post-operative day respectively in good clinical state. The mother was given appointment to the family planning clinic. Conclusion: We presented a patient with a rare congenital clinical condition – uterine didelphys who conceived spontaneously. She had a previous successful pregnancy on the right uterus followed by a spontaneous miscarriage and successfully carried the index pregnancy on the left uterus to term and was delivered by an elective repeat caesarean section with good fetal and maternal outcome.
