Application research of radial artery angiography in advance on transradial coronary intervention / 中国医师进修杂志

ABSTRACT

Objective To study the feasibility and necessity of radial artery angiolgraphy in advance on transradial coronary intervention.Methods A total of 682 patients undergoing transradial coronary intervention were divided into two groups by random digits table method.Previous radial artery angiography (pre-RAA) group of 341 cases underwent radial artery angiography;post radial artery angiography (post-RAA) group of 341 cases in the guide wire,catheter in resistance immediately for radial artery angiography.The radial artery imaging characteristics were observed and the radial artery related complications were recorded in two groups.Results The ratio of radial artery spasm in post-RAA group was higher than that in pre-RAA group [11.4％(39/341) vs.6.2％(21/341),P=0.015].The ratio of operation failed in post-RAA group was higher than that in pre-RAA group [3.2％ (11/341) vs.0.6％ (2/341),P =0.014].The radial artery perforation rate and postoperative 1-6 months of radial artery occlusion rate increased significantly in post-RAA group,and there was significant difference between two groups (P ＜ 0.05).Conclusion Transradial coronary intervention in advance for radial artery angiography therapy can effectively observe the radial artery morphology,reduce the radial artery related complications.
