    Abstract:
    Placenta percreta involving adjacent structures is serious complication of pregnancy with a high mortality rate. A 32-year-old woman, gravida 4, para 3, who had previously undergone a cesarean section, was admitted to our hospital at 31 weeks' gestation for placenta previa. At 33 weeks' gestation, the diagnosis of placenta percreta with involvement of the urinary bladder was made by ultrasonography and magnetic resonance imaging. At 34 weeks' gestation, an elective cesarean section was scheduled. Anesthesia was maintained with sevoflurane in oxygen before delivery, and with nitrous oxide in oxygen, fentanyl and midazolam after delivery. During the operation, attempts to remove the placenta resulted in massive hemorrhage. Blood loss for the procedure was 13,800 g. Because of the extreme hemorrhage, we encountered hemorrhagic shock and postoperative complications despite the preoperative preparation. In case of placenta percreta, it is essential to prepare adequate volume of blood for transfusion at the start of surgery and secure large bore intravenous lines. A rapid transfusion device may be recommended. Regarding the anesthetic management, general anesthesia is preferable in consideration of the risk of hemorrhagic shock and the length of operation time. Furthermore, we need team approach and preoperative management to prevent the uncontrolled hemorrhage in such a severe case.
