Abstract：Objective To investigate the safety and efficacy of high-intensity focused ultrasound(HIFU)combined with suction curettage under hysteroscopic guidance for cesarean scar pregnancy(CSP)and to analyze the influencing factors of vaginal bleeding and readmission.Methods From January 2014 to September 2017 in the Third Xiangya Hospital of Central South University,367 patients with cesarean scar pregnancy were treated by HIFU combined with suction curettage under hysteroscopic guidance.All the patients received one session of HIFU ablation. Their clinical data were analyzed and the treatment effect and safety were observed.Results After HIFU treatment,the fetal cardiac activity disappeared and the blood flow around the sac was significantly decreased. The median volume of blood loss in the suction curettage was 20(range 5～600)mL.The volume of vaginal bleeding is related to the largest diameter of the sac,and the risk of large vaginal bleeding of patients was increased with larger diameter of the sac(P=0.015). The risk of readmission is related to the volume of vaginal bleeding,the risk of readmission of patients was increased with larger vaginal bleeding (P=0.000).No serious complication was observed.Conclusion HIFU combined with suction curettage under hysteroscopic guidance is effective in treating patients with CSP of typeⅠ and type Ⅱ.
