Postpartum hemorrhage is considered to be a serious complication in patients with pernicious placenta. Approaches employing abdominal aortic balloon occlusion to control hemorrhage are extremely effective for such patients. The present study analyzed 9 patients with pernicious placenta previa in a single hospital from June 2016 to November 2017. Prior to cesarean hysterectomy, an abdominal aortic balloon catheter was placed in all patients. The balloon was inflated and evacuated alternately using saline following delivery of the fetal head. The X-ray dose, bleeding volume and complications during the procedure were observed. Balloon catheterization was successfully performed in all 9 patients. The dose of X-rays ranged from 15.8 to 24.5 mGy, with a mean of 19.3±2.7 mGy; the volume of blood loss ranged from 50 to 4,000 ml, with a mean of ~1,800 ml. Uterine artery embolization was successfully performed in 2 cases due to bleeding following the cesarean hysterectomy, and every uterus was retained. Abdominal aortic balloon occlusion can effectively reduce the amount of bleeding during cesarean hysterectomy in patients with pernicious placenta previa. This may serve as technical support for patients in whom retention of the uterus is expected. However, it is necessary to identify any abnormal uterine tissue above the level of the renal artery in order to avoid ineffective balloon occlusion.
