摘　　要：目的评估血管机低剂量系统在经导管治疗房间隔缺损(Atrial Septal Defect,ASD)手术中的优势,探讨术中放射及辐射剂量降低的因素和方法。方法2018年7月至2019年12月接受经导管治疗ASD的患者共339例,分为FD10 Clarity系统和FD10系统两组,通过收集各组手术的剂量面积乘积(Dose Area Product,DAP)、辐射剂量空气比释动能(Air Kerma,AK)数据,统计分析两组的差异性。结果FD10 Clarity系统得到的平均DAP值为5702 mGy.cm2,低于FD10系统的8576 mGy·cm2,降低了33.51%;FD10 Clarity系统得到的平均AK值为34.41 mGy,低于FD10系统的74.94 mGy,降低了54.08%。结论血管机低剂量系统在经导管治疗房间隔缺损心脏病手术中,较传统血管机系统,有着明显的射线剂量优势。Objective To evaluate the advantages of low dose vascular system in transcatheter atrial septal defect(ASD)surgery,and to explore the factors and methods of dose reduction of intraoperative radiation and radiation.Methods From July 2018 to December 2019,339 patients received transcatheter treatment of ASD were divided into two group:FD10 clarity system and FD10 system.The difference between the two groups was statistically analyzed by collecting the data of dose area product(DAP)and air kerma(AK).Results The average DAP value of FD10 clarity system was 5702 mGy.cm2 which was lower than 8576 mGy.cm2 of FD10 system,decreased by 33.51%;the average AK value of FD10 clarity system was 34.41 mGy,lower than 74.94 mGy of FD10 system,decreased by 54.08%.Conclusion Compared with the traditional vascular system,the low dose vascular system has an obvious advantage of radiation dose in the transcatheter treatment of ASD heart disease.
