Meta-analysis of RCT Studies on Coronary Intervention Through Distal Radial Artery and Traditional Radial Artery Approach
Objective To evaluate the success rate,puncture time and incidence of puncture complications between distal radial artery approach and transradial artery approach in coronary intervention by Meta-analysis.Methods PubMed,EMbase,Cochrane Library,Si-nomed,China National Knowledge Infrastructure(CNKI),Wanfang Data,VIP and other databases were searched by computer.Three researchers independently collected data,and two researchers assessed the data content and used RevMan5.3 software for meta-analysis.Results A total of 12 RCT studies involving 4886 patients were included.Compared with the traditional radial artery puncture approach,the success rate of distal radial artery puncture was lower(OR=6.73,95%CI:4.58-9.90,P<0.000 01,Z=9.69),the success rate of one-time puncture was lower(OR=2.86,95%CI:2.37-3.45,P<0.000 01,Z=10.96),and the puncture time was longer(OR=0.73,95%CI:0.40-1.06,P<0.000 1,Z=4.30),the occlusion rate of distal radial artery approach was lower(OR=0.25,95%CI:0.18-0.35,P<0.000 01,Z=7.98).There was no significant difference in local hematoma(OR=0.88,95%CI:0.64-1.21,P=0.43,Z=0.80)and radial artery spasm(OR=1.00,95%CI:0.62-1.61,P=0.99,Z=0.01)between the two groups.Conclusion Compared with the traditional radial artery approach,the distal radial artery approach has a lower puncture success rate and a longer puncture time during coronary intervention.There is no significant change in the incidence of local hematoma and radial artery spasm,but it can effectively avoid radial artery occlusion.
