title: Hyperkalemia and acute kidney failure associated with preoperative uterine artery embolization for a large uterine fibroid: a case report.
abstract: BACKGROUND
  Preoperative uterine artery embolization has been shown to help reduce blood loss, with few complications. Most reports indicated that uterine artery embolization is safe for uterine fibrosis; the occurrence of hyperkalemia and acute kidney failure as complications of preoperative uterine artery embolization has not been reported previously. Here we report the occurrence of hyperkalemia and acute kidney failure after preoperative uterine artery embolization for a large uterine fibroid. To the best of our knowledge, this is the first report on the occurrence of hyperkalemia and acute kidney failure after preoperative uterine artery embolization.
  
  
  METHODS
  A 48-year-old Japanese woman presented to our hospital complaining of compression in her abdomen and an abdominal mass. Magnetic resonance imaging showed a large uterine fibroid measuring 37.5×27×13.5 cm. Therefore, we planned preoperative uterine artery embolization to help reduce blood loss. However, hyperkalemia and acute kidney failure occurred owing to the development of necrotic tissue after uterine artery embolization; therefore, emergency total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. She experienced 105 g of blood loss intraoperatively. The weight of her uterus was 10.8 kg and the volume was 9964 cm3, with extensive necrotic tissue. Her hyperkalemia and kidney failure resolved after the surgery.
  
  
  CONCLUSIONS
  We reported the occurrence of serious complications, including hyperkalemia and acute kidney failure, after preoperative uterine artery embolization for a large uterine fibroid.
