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.
