We reported a uterine rupture which occurred during spontaneous labor and delivery in a primiparous woman, who had no past history of uterine scar. A Japanese woman progressed to labor at 39 weeks of gestation. The fetal heart rate(FHR)monitoring showed reassuring patterns. Suddenly, 2 hours later, baseline FHR became tachycardiac(180 bpm)and there were repeated severe decelerations. Uterine contractions were not changed. Maternal heart rate, respiration, blood pressure and body temperature were stable. She did not suffer from abdominal pain or dyspnea. We performed a cesarean section and noticed a complete uterine rupture after delivering the baby. Both the mother and newborn were healthy and discharged at 13 days. Uterine rupture of art unscarred uterus during spontaneous delivery is extremely rare and severe FHR deceleration is thought to be an important manifestation of uterine rupture.
