目的评价子宫动脉栓塞术在剖宫产术后瘢痕妊娠中的临床疗效。方法回顾性分析67例剖宫产术后瘢痕妊娠患者的临床资料。将患者分为栓塞组(n=35)和甲氨蝶呤组(n=32),2组患者均行宫腔镜手术治疗,栓塞组行双侧子宫动脉栓塞术,甲氨蝶呤组肌肉注射甲氨蝶呤。观察2组患者术中出血量、住院时间、术后血人绒毛膜促性腺激素(HCG)转阴时间、月经恢复时间、病灶消失时间等指标,并进行比较。结果 2组患者治疗后血HCG转阴时间、住院时间、病灶消失时间及术中出血量比较,差异均有统计学意义(P<0.05);月经恢复时间2组间比较差异无统计学意义(P>0.05)。2组不良反应发生情况比较差异无统计学意义(P>0.05)。结论子宫动脉栓塞联合宫腔镜下清宫术治疗剖宫产术后瘢痕妊娠安全、有效。 Objective To evaluate the clinical efficacy of uterine artery embolization in cesarean scar pregnancy. Methods The clinical data of 67 patients with scar pregnancy after cesarean section were retrospectively analyzed. The patients were divided into embolization group (n = 35) and methotrexate group (n = 32). Hysteroscopic surgery was performed in both groups. Bilateral uterine arterial embolization Methotrexate. The blood loss, length of hospital stay, postoperative HCG time, menstruation recovery time and disappearance time were observed and compared in two groups. Results There were significant differences in HCG negative time, hospitalization time, disappearance time and blood loss after operation between the two groups (P <0.05). There was no significant difference between the two groups in recovery time of menstruation P> 0.05). There was no significant difference in adverse reactions between the two groups (P> 0.05). Conclusion Uterine artery embolization combined with hysteroscopic curettage of cesarean scar pregnancy is safe and effective.
