title: Successful treatment of endogenous cesarean scar pregnancies with transabdominal ultrasound-guided suction curettage alone.
abstract: OBJECTIVE
  To investigate the efficacy and safety of transabdominal ultrasound-guided suction curettage alone in endogenous cesarean scar pregnancy (CSP).
  
  
  METHODS
  From 2009 to 2013, 21 women with endogenous CSP who had no other therapy underwent suction curettage alone guided with transabdominal ultrasound.
  
  
  RESULTS
  All patients were successfully treated with suction curettage alone. No one needed emergency blood transfusion or uterine artery embolization. The average gestational age was 51.1±7.56 days. The mean thickness of the lower anterior uterine wall was 0.5cm, ranging from 0.3cm to 0.9cm. The average blood loss during surgery was 81.3±33.5 (30-150)ml. The mean time for achieving a normal β-HCG level was 26.9 days.
  
  
  CONCLUSIONS
  Transadominal ultrasound-guided suction curettage was a feasible and effective method for lower risk endogenous CSP patients with the myometrial layer between the gestational sac and the bladder more than 3mm before 10 gestational weeks.
