Spontaneous pregnancy at term with uterus didelphys: a case report

Abstract

The uterus didelphys results from the absence of fusion of the bilateral mullerian ducts. It is a rare pathology. This malformation concerns 5% of uterine malformations from mullerian ducts and affects one woman in 1,000-30,000. Obstetrical complications of this malformation are numerous. The chance of reaching term for pregnancies with didelphys uterus is reported as 20%–30%. Authors report a case of spontaneous term pregnancy in a 21-year-old primiparous woman with a didelphic uterus. The patient had an unexplained seizure with fetal bradycardia. An emergency cesarean section was performed and allowed the birth of a hypotropic neonate of 2240g and the discovery of didelphic uterus. Pregnancy developed in the left hemi-uterus. Speculum examination at the end of the procedure showed a longitudinal vaginal septum. There was no associated urinary tract and renal malformation. Scheduled cesarean will be performed from her next pregnancy. The uterus didelphys should be diagnosed early. MRI and 3D echography are necessary for diagnosis. Pregnancy is often complicated, and follow-up needs to be planned. Cesarean section is not systematic.
