Placental Abruption and Partial Placental Prolapse During Labor Induction With a Cervical Double Balloon (Cook Catheter) in a 37-Year-Old Patient.

Placental abruption is a major obstetric emergency. To date, no cases of placental abruption associated with partial placental prolapse during labor induction with a cervical double-balloon catheter have been reported. We describe the case of a 37-year-old nulliparous woman (G2P0010) with a pregnancy conceived by assisted reproductive technology and complicated by late-onset fetal growth restriction. At 39 weeks of gestation, labor induction was initiated using a cervical double-balloon catheter because of an unfavorable cervical status. Shortly after insertion, the patient developed acute placental abruption with partial prolapse of a posteriorly inserted placenta, requiring emergency cesarean delivery. This case highlights that placental abruption may occur in temporal association with mechanical cervical ripening and underscores the potential for delayed diagnosis when a cervical double-balloon catheter is in place, as early clinical signs such as vaginal bleeding may be partially obscured.
