摘　　要：目的　研究子宫肌瘤患者在子宫动脉栓塞 (UAE)手术中所经受的X射线照射。方法　回顾性分析 90例UAE辐射剂量资料 ,采用DSA机 (Angiostar Plus)配置的空透电离室型剂量监测系统 (DiamentorK1andDiamentorED) ,在线读取面积剂量乘积DAP(cGy·cm2 )和入射表面剂量ESD(mGy) ,采用Monte Carlo转换因子估算有效剂量ED(mSv)。结果　透视时间 (2 8. 60± 2 3 . 73 )min ,摄影 (87± 3 8)帧 ,DAP为 (6178± 3 80 2 )cGy·cm2 ,ESD为 (3 78± 2 45 )mGy ,ED为 (9 .89± 6. 0 8)mSv。透视对总DAP的贡献 (3 4 1%± 10 7% )小于摄影 (65. 9%± 10 . 7% ) ,透视对ESD值的贡献 (61 .1%± 12 . 9% )大于摄影 (3 9 .5 %± 14. 0 % )。结论　UAE治疗过程中患者受到了一次性较大剂量X射线照射。Objective To evaluate the X-ray radiation of patients during uterine artery embolization (UAE) for leiomyomas. Methods Radiation dose was measured in 90 patients who underwent UAE for leiomyomas. Measurements were obtained by a dosimeters system (Diamentor K1 and Diamentor ED) equipped in DSA setting Angiostar-Plus (Siemens, Germany), dose-area product (DAP) and entrance surface dose (ESD) were recorded on line, effect dose (ED) was estimated by Monte-Carlo conversion coefficient from DAP. Results The mean fluoroscopic time was 28.60±23.73 minutes, and the mean number of angiographic exposures was 87±38. The mean DAP dose was (6 178±3 802)cGycm2, and the mean ESD was 378±245)mGy , ED was (9.89±6.08)mSv. The contribution of pulsed fluoroscopy(PF) dose to the total DAP (34.05%±10.65%) was smaller than that of radiography (R) (65.94%±10.65%), and the contribution of PF for total ESD (61.09%±12.88%) was bigger than that of R (65.94%±10.65%). Conclusion The leiomyoma patient suffered a large dose X-ray exposure from a UAE procedure.
