Case of successfully delivered dicavitary twins in uterus didelphus

Uterus didelphus is a congenital abnormality arising from failure of fusion of Mullerian ducts, creating two separate uterine horns, two cervices and, in some cases, a vagina divided by a longitudinal septum. In this case, a 26-year-old woman with previously undiagnosed uterus didelphus spontaneously conceived dicavitary twins. Although initially wanting a vaginal birth, when both twins were in a breech presentation, a caesarean section was performed at 36 weeks, delivering two healthy babies. We will discuss the risk of obstetric complications in uterus didelphus and the challenges surrounding a vaginal delivery.
