近年来经桡动脉途径进行冠状动脉介入术已日渐普遍,但对于该种术式所受放射剂量的多少颇有争议。本文研究经桡动脉或股动脉两种不同术式术者所受的放射量的差异,结果证实,经桡动脉术式较股动脉术式术者所受放射量大大增加。研究收集了297例冠状动脉介入治疗的患者,其中195例为 In recent years, transradial approach to coronary artery intervention has become increasingly common, but for the operation of the amount of radiation dose is quite controversial. This study investigates the difference in the amount of radiation experienced by two different surgical approaches to the radial artery or femoral artery. The results show that the amount of radiation received by transradial surgery versus femoral artery surgery is significantly increased. The study collected 297 patients with coronary intervention, of which 195 were
