【目的】探讨子宫动脉化疗栓塞联合超声清宫术治疗剖宫产瘢痕妊娠(cesarean scar pregnancy,CSP)的疗效。【方法】收集CSP患者42例,根据患者意愿分为两组：子宫动脉化疗栓塞联合清宫22例为观察组；直接清宫20例为对照组,两者均在超声监视下清宫术。比较两组术中出血量、手术时间长短、术中大出血发生率及并发症。【结果】两组术前年龄、剖宫产次数、流产次数、停经时间、血人体绒膜促性腺激素(HCG)及孕囊直径比较差异均无统计学意义(P >0.05)。观察组清宫术中出血量10~30 mL,均未发生大出血,对照组术中出血量300~2000 mL,其中发生大出血8例；观察组出血量及大出血发生率均明显小于对照组(P 0.05)。【结论】子宫动脉化疗栓塞联合超声清宫术治疗CSP能有效地减少出血量,控制大出血的发生率,缩短手术时间,是 CSP 的有效治疗方法,值得临床推广应用。“,”Obj ective]To study the efficacy of uterine artery chemoembolization combined with ultrasonic curettage for the treatment of cesarean scar pregnancy (CSP).[Methods]Forty-two CSP patients were collected and divided into two groups according to the wishes of patients:22 cases of uterine artery chemoembolization curettage as the observation group;20 cases of direct curettage as the control group,both underwent ultrasonic monitoring curettage.The bleeding volume,operation time,the incidence of bleeding and complications were compared between the two groups.[Results]Preoperative indexes like age,times of cesarean section,times of abortion,menopause,blood human chorionic stimula-ting gonadotropin (hCG)and the gestational sac diameter difference of two groups had no statistical significance (P >0.05).The amount of bleeding of uterine curettage of the observation group was 10~30 mL,there were no massive bleeding,bleeding of the control group was 300~2000 ml,hemorrhage occurred in 8 cases;Amount of bleeding in the observation group and bleeding incidence was significantly lower than the control group (P0.05).[Conclusion]Uterine artery chemoembolization combined with ultrasonic curettage for the treatment of CSP can ef-fectively reduce the amount of bleeding and control the incidence of maj or bleeding,shorten operative time,and is an ef-fective method for the treatment of CSP,which is worth of clinical application.
