Percutaneous coronary intervention in patients with acute myocardial infarction by radial artery approach using 6F judkin angiographic catheter:a clinical analysis

Objective To discuss the feasibility of percutaneous coronary intervention(PCI)in patients with acute myocardial infarction(AMI)by radial artery approach using 6F Judkin angiographic catheter during radial artery spasm.(Shanghai Med J,2010,333:744-746)Methods Eighteen AMI patients who received PCI by radial artery approach with 6F Judkins angiographic catheter due to tortuous radial artery and/or radial artery spasm and another 20 AMI patients who received PCI by transfemoral approach due to radial problems were enrolled in this study.The clinical data,the characteristics of target lesion,the status of PCI,the successful rate of operation,the operation time of implanting stent(from 0.014″ wire entering the catheter to implanting stent),the door-to-balloon(DTB)time,the operation time,the amount of contrast media,and the complications after operation were all observed.Results The clinical baseline data were similar in the two groups.The successful rate of operation was 17/18 in group A and 20/20 in group B(P0.05).The amount of contrast media was(155±42)mL in group A and(163±56)mL in group B(P0.05).The fluoroscopy time during catheterization was(17±3)min in Group A and(15±6)min in Group B(P0.05).The operation time of implanting stent was 12(7,22)min in group A and 14(9,20)min in group B(P0.05).The operation time and the DTB were significantly shorter in the group A than in group B([40±8] vs.[58±7],P0.01;[114±28] min vs.[148±32] min,P0.05).Conclusion It is feasible to perform PCI in AMI patients by radial artery approach using 6F Judkin angiographic catheter when there are tortuous radial pathways and/or the radial artery spasm.(Shanghai Med J,2010,33:744-746)
