【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,P0.001)。DSA曝光次数的差异无统计学意义(P0.05)。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。
[Abstract]:Objective to investigate the feasibility of low dose DSA and fluoroscopy in uterine artery chemoembolization in ectopic pregnancy. Methods 42 cases of uterine ectopic pregnancy (13 cases of cervical pregnancy, 27 cases of scar pregnancy) with body mass of 48~61kg were collected. Two cases of uterine horn pregnancy were randomly divided into two groups: group A (n = 21) and group B (n = 21). The body weight, operation time, cumulative exposure time and the product of DSA exposure times and radiation dose area were compared between the two groups. Results there was no significant difference between the two groups in the mean body mass, mean operation time, mean exposure time and average exposure time. There was significant difference in radiation dose area product between the two groups. There was no significant difference in the number of exposures between the two groups (P 0.05). Conclusion low dose DSA and fluoroscopy are effective and feasible for uterine arterial chemoembolization in patients with ectopic uterine pregnancy, and can significantly reduce the radiation dose received by the patients.
