Abstract: Objective:To discuss the clinical effectiveness and safety of the curettage combined with uterine artery embolization in the treatment of endogenic cesarean scar pregnancy(CSP).Methods:Seventy patients with endogenic CSP were treated with uterine curettage guided by color Doppler ultrasound after 72h of uterine artery embolization.The successful rate of abortion,peroperative bleeding,postoperative bleeding,intrauterine residue,time of β-hCG andmenstruation returning to normal,and complication in all patients were observed.Results:All operations in 70 cases were successfully,and the abortion rate was 98.57%(69/70).The mean bleeding during operation was(23.33+47.22)mL.The time of β-hCG and menstruation returning to normal were(20.73±5.53) and(40.97±8.97) days after operation,respectively.There was no intrauterine residue under abdominal color Doppler ultrasound after 1 week of curettage.There was no complication among all patients.Conclusions:The curettage combined with uterine artery embolization in the treatment of CSP has high success rate,less bleeding,fewer complications,is safe and effective,which is worthy of clinical promotion.
