摘　　要：目的探讨低剂量技术DSA及透视在子宫异位妊娠患者子宫动脉化疗栓塞术中应用的可行性。方法收集42例体质量为48~61kg的子宫异位妊娠患者（宫颈妊娠13例,瘢痕妊娠27例,宫角妊娠2例）,随机分为低剂量采集模式组（A组,n=21）和标准剂量采集模式组（B组,n=21）,均由同一位主治医师完成两侧子宫动脉化疗栓塞术。对两组患者的体质量、手术时间、曝光累计时间、DSA曝光次数和辐射剂量面积乘积进行对比分析。结果两组患者均顺利完成介入手术;A、B两组在平均体质量（t=0.575,P=0.568）、平均手术时间（t=-0.385,P=0.702）、平均曝光时间（t=0.435,P=0.666）方面差异均无统计学意义;在辐射剂量面积乘积方面两组差异有统计学意义（t=-9.588,P〈0.001）。DSA曝光次数的差异无统计学意义（P〉0.05）。结论采用低剂量技术DSA及透视对子宫异位妊娠患者行子宫动脉化疗栓塞术有效可行,并可显著降低患者所接受的手术辐射剂量。Objective To investigate the feasibility of low-dose DSA and low-dose fluoroscopy in patients with uterus ectopic pregnancy who received chemoembolization by uterine artery.Methods Totally 42 patients with uterus ectopic pregnancy,whose weight between 48 to 61kilogram（13cases of cervical pregnancy,27 cases of scar pregnancy,2cases of uterine horn pregnancy）were enrolled and randomly divided into group A（n=21）using low-dose acquisition mode and group B（n=21）using standard-dose acquisition mode.All patients received the uterine artery chemoembolization,and the operations were completed by the same physician.The weight,operative time,cumulative exposure time,DSA exposure times and radiation dose area product of the two groups were analyzed.Results All patients were successfully completed interventional therapy.The mean body weight（t=0.575,P=0.568）,mean operative time（t=-0.385,P=0.702）,the average exposure time（t=0.435,P=0.666）were no significant difference between group A and group B.There was significant difference（t=-9.588,P〈0.001）in radiation dose area product between group A and group B.The DSA exposure times of the two groups had no significant difference.Conclusion Using low-dose DSA and low-dose fluoroscopy in the patients with uterus ectopic pregnancy who need uterine artery chemoembolization is effective and feasible,and it can significantly reduce the radiation doses of the patients during the interventional therapy.
