A successful vaginal birth after cesarean in a patient with uterine didelphys

Abstract

Abstract Objectives With increasing rates of cesarean delivery across the United States, a trial of labor after cesarean (TOLAC) is a reasonable alternative for qualified candidates. Although Müllerian anomalies are associated with a variety of adverse pregnancy outcomes, there is little existing data regarding TOLAC in these patients. We present a case of a patient with a didelphys uterus who achieved a successful vaginal birth after cesarean section (VBAC) in the setting of labor augmentation. Case presentation Our patient is a 32-year-old G4P1021 (Gravida 4 Para 1,021–1 term delivery, 0 preterm deliveries, 2 abortions, 1 living offspring) who presented at 8 weeks of gestation with a known history of a didelphys uterus. Her obstetrical history was significant for a prior low-transverse cesarean section at term. All four of her pregnancies were located in the right uterine horn. At 39 weeks 3 days of gestation she presented in early labor and requested a TOLAC. She received an epidural, a cervical ripening balloon was placed, and she was started on pitocin. She pushed to deliver a viable infant. The patient’s postpartum course was uncomplicated, and she was discharged home on postpartum day two. Conclusions Müllerian anomalies are associated with several poor pregnancy outcomes including increased rates of PPROM, preterm delivery, FGR, and malpresentation necessitating a cesarean section. Our patient required augmentation of her labor but was ultimately able to achieve a successful VBAC with a healthy neonate. She represents an understudied population of patients with uterine anomalies who not only can have favorable pregnancy outcomes but may even be able to safely achieve a VBAC.
