摘要
为了解儿童先天性心脏病(CHD)介入治疗的情况及受照剂量,为制定患儿CHD介入治疗剂量指导水平提供参考资料,对2017年在本市某三甲医院进行数字减影血管造影机(DSA)介入治疗的297例先天性心脏病患儿,进行了回顾性调查。调查内容包括患儿的信息、管电压(kV)、管电流(mA)、透视时间、造影帧数、累积剂量、剂量面积乘积等参数。结果表明:本次调查中先天性心脏病介入治疗类型以室间隔缺损封堵术(VSD)最多;各年龄组和性别差异无统计学意义;术中透视时间最长的是射频消融术(RFCA),摄影帧数最多的是VSD封堵术,各组间透视时间差异无统计学意义(p>0.05),各组间摄影帧数差异有统计学意义(p<0.05);DSA自身记录的累计剂量(CD)和剂量面积乘积(DAP)中,最高的为VSD封堵术,不同疾病类型中CD差异有统计学意义(p<0.05),DAP差异无统计学意义(p>0.05)。通过本次调查了解了近年来CHD介入治疗的基本情况,主要以4种手术类型所占比例最高,其他年龄和性别差异不显著,DAP和CD结果范围与其他学者给出的范围无较大出入。
A retrospective investigation of 297 children with congenital heart disease(CHD)was conducted,to understand the status and exposure doses of interventional treatment for children with congenital heart disease and provide reference for formulating the guidance level of CHD interventional treatment in children.These children have underwent digital subtraction angiography(DSA)in a 3A hospital in Jinan in 2017.The patient′s information,tube voltage(kV),tube current(mA),fluoroscopy time,contrast frame number,cumulative dose,dose area product and other parameters were inquired.It showed that the most common type of interventional treatment for CHD was ventricular septal defect(VSD)closure,with the highest cumulative dose(CD)and the dose area product(DAP)recorded by DSA.The differences in ages and genders were not significant.The dose results are not significantly different from those given by other scholars.
