摘要
目的 获得心血管介入诊疗患者峰值皮肤剂量(PSD)数据,评估患者确定性效应发生风险.方法 使用Gaf-chromic XR RV3胶片剂量计采集北京市某三级甲等医院进行心血管介入诊疗患者的峰值皮肤剂量,主要研究冠状动脉造影术、经皮冠状动脉腔内血管成形术、射频消融术、先天性心脏病介入治疗等常见的手术类型.使用EPSON EX-PRESSION 10000XL扫描仪扫描胶片,FILM QA ProTM 2014软件测量和分析胶片.结果 共采集 59例心血管介入诊疗患者的峰值皮肤剂量数据,包括冠状动脉造影术 23例、经皮冠状动脉腔内血管成形术 21例、射频消融术 9例、先天性心脏病介入治疗 6例.PSD≥2 Gy患者 7例,均为经皮冠状动脉腔内血管成形术,其中 1例PSD超过 3 Gy,其余均小于 2 Gy.结论 部分心血管介入诊疗患者的PSD超过国际放射防护委员会第 118号报告中的确定性效应剂量阈值,提示心血管介入诊疗存在确定性效应发生风险,其中经皮冠状动脉腔内血管成形术患者风险较高.
Abstract
Objective To obtain the peak skin dose(PSD)of patients with interventional cardiology procedures and to evaluate the risk of deterministic effects.Methods Gafchromic XR RV3 films were used in a Level A tertiary hospital in Beijing to measure the PSD of patients who underwent interventional cardiology procedures.The measurement focused on four common types of procedures,including coronary angiography,percutaneous transluminal coronary angioplasty,cathet-er radiofrequency ablation,and congenital heart disease.The films were scanned by EPSON EXPRESSION 10000XL and analyzed by FILM QA ProTM 2014 software.Results PSD was measured in 59 patients with interventional cardiology pro-cedures,including 23 with coronary angiography,21 with percutaneous transluminal coronary angioplasty,9 with catheter radiofrequency ablation,and 6 with congenital heart disease.The seven patients with PSD≥2 Gy all underwent percu-taneous transluminal coronary angioplasty,one with PSD>3 Gy and six with PSD<2 Gy.Conclusion The PSD of some patients with interventional cardiology surgery exceeded the dose threshold of deterministic effects recommended by the ICRP 118.There is a risk of deterministic effects in interventional cardiology surgery,especially in patients with percu-taneous transluminal coronary angioplasty.
