不同路入途径行冠状动脉介入时患者辐射剂量的对比研究

[目的]对比测定经股动脉和桡动脉路入途径行冠脉造影时患者的受照剂量,为心血管介入辐射防护提供参考。[方法]在2010年1月～2011年1月,男性患者60例行冠脉造影,按其血管途径分为桡动脉组30例和股动脉组30例,桡动脉途径组患者行Allen’s试验呈阳性,选右桡动脉入径,股动脉途径组按常规方法操作,用穿透电离室型剂量测量系统,对不同路入途径行冠状动脉介入时患者辐射剂量进行了测量。所得数据资料,采用SPSS10.0软件进行统计学分析,P﹤0.05为差异有统计学意义。[结果]两组造影途径的患者体重、胸部体厚、透视时间和曝光帧数没有明显差异,但患者累积剂量桡动脉组(825±338mGy)明显高于股动脉组(541±204mGy),两组结果进行比较,差异有统计学意义(P﹤0.05)。[结论]桡动脉途径因为成功率高、并发症少成为冠心病介入治疗的首选途径同时,患者所接受的辐射剂量较大,应该采取有效措施来加强对患者的辐射防护。

COMPARISON OF PATIENTS' EXPOSURE DOSE DURING CORONARY ANGIOGRAPHY BY RADIAL AND FEMORAL APPROACH

[Objective]The aim of this study was to measure and comparison of patient's exposure dose during coronary angiography by radial and femoral approach,meanwhile these exposure dose data obtained from the study can supply reference on radiation protection during coronary angiography and interventional procedures.[Methods]From January 2010 to January 2011,the coronary angiography was performed randomly either from a femoral or a radial approach by the same operator with vast experience.The radial approach was p...
