摘　　要：目的比较新型无导线起搏器与传统单腔起搏器(VVI)植入术中X线投照剂量的差异。方法收集四川大学华西医院2018年8月3日至2020年2月18日内,由同一教授团队在同一台数字减影血管机(DSA)上完成的全部无导线起搏器植入及VVI植入病例资料。将无导线起搏器27例设为病例组,VVI植入术38例为对照组。比较两组患者术中剂量面积乘积(DAP)、空气比释动能(AK)、手术X线透视时长、电影曝光序列数、电影合计帧数、手术时长、患者BMI等,分析造成差异的原因。结果病例组X线投照剂量高于对照组,两组在DAP、AK、手术X线透视时长、电影曝光序列数、电影合计帧数、手术时长方面差异均有统计学意义(P<0.05)。结论与传统VVI植入相比,无导线起搏器植入患者接受的X线辐射更多。Objective To compare the X-ray projection doses during leadless pacemaker implantation and conventional single chamber ventricular pacemaker(VVI)implantation.Methods This study included all patients who underwent leadless pacemaker implantation and VVI pacemaker implantation performed by the same principal investigator team using the same digital subtraction angiography(DSA)machine in the West China Hospital of Sichuan University from August 3rd,2018 to February 18th,2020.Among the enrolled patients,27 who underwent leadless pacemaker implantation were included in the case group,whereas 38 who underwent conventional VVI implantation were included in the control group.Data regarding the intraoperative dose area product(DAP),air kerma(AK),duration of X-ray fluoroscopy,number of exposed sequences on the film,total number of frames on the film,operation time,and BMI were collected to investigate the causes of the differences.Results The case group received a higher X-ray projection dose than the control group,and there were statistically significant differences between the two groups in terms of DAP,AK,duration of X-ray fluoroscopy,the number of exposed sequences on the film,the total number of frames on the film,and operation time(P<0.05).Conclusion Patients who underwent leadless pacemaker implantation are exposed to more radiation than those who underwent conventional VVI implantation.
