Twin pregnancy in each half of a didelphys uterus with delayed delivery and review of literature
Abstract
Abstract Didelphys uterus results from an incomplete fusion of mullerian ducts and corresponds to the class III of mullerian abnormalities of the American Fertility Society. We describe the case of a spontaneous twin pregnancy developed in each cavity of a didelphys uterus. At 29 weeks of gestation and 6 days, the patient had preterm rupture of membranes in the right horn. She went into spontaneous labor and delivered vaginally the first “right” twin. Delivery was complicated with post-partum hemorrhage on uterine atonia treated with a Bakri balloon. She was tocolyzed to pursue the fetal lung maturity of the second twin. She had a rupture of the second membranes at 30 weeks and 3 days and had a preterm vaginal delivery at 32 weeks and 1 day of the second twin. Twin pregnancy in both horns of a uterus is extremely rare, about 1 in 1,000,000. Pregnancies on congenital abnormalities of the paramesonephric duct present frequently poor obstetrical outcomes and many complications. There are no guidelines about the follow-up of these high-risk patients or the mode of delivery.
