A 40-year-old woman with a history of cesarean section and 3 episodes of uterine curettage for spontaneous or induced abortion presented with massive genital hemorrhage in the ninth week of gestation; she was treated with red cell concentrate and fresh frozen plasma transfusion. She was admitted to our hospital at the 11th week of gestation for continuous genital hemorrhage and cervical shortening (20 mm). Ultrasonography revealed placenta previa totalis. A lowlying gestational sac in early pregnancy, vascular lacunae, and an obscured retroplacental sonolucent zone indicated placenta percreta; magnetic resonance imaging showed similar findings. Owing to placenta percreta, uterus preservation was considered impossible. Elective cesarean section followed by total hysterectomy was performed at the 37th week of gestation, with bilateral internal iliac artery balloon catheter occlusion for reducing blood loss. The perioperative blood loss was 2,835 mL, for which the patient received blood transfusion. The postoperative course was uncomplicated.
