Antepartum unscarred uterine rupture caused by placenta percreta: a case report and literature review

The main risk for uterine rupture is the presence of a uterine scar due to prior cesarean delivery or other uterine surgery. However, rupture in an unscarred uterus is extremely rare, and risk factors include multiple gestations, trauma, congenital anomalies, use of uterotonics and placenta accreta spectrum. Placenta accreta spectrum, also known as morbidly adherent placenta, is becoming increasingly common and is associated with significant maternal and neonatal morbidity and mortality. We report a case of unscarred uterine rupture due to placenta percreta in a multiparous woman that required emergency peripartum hysterectomy.
