How to Improve the Success Puncture Rate of Distal Transradial Artery Approach, "Winding Path to the Secluded": Summary of the Experience of More than 2 000 Cases

Percutaneous coronary diagnosis and intervention via distal transradial artery approach has become one of the hot research topics in the field of coronary angiography and intervention. Compared with transradial approach, the distal transradial artery approach has the advantages of higher patient comfort and fewer related complications; however, due to the tortuosity of radial artery and relatively small size of distal radial artery, there is a significant learning curve for distal transradial artery approach puncture. This paper analyzes and summarizes the common causes (mainly including patient factors and operational factors) and treatment strategies of distal transradial artery approach puncture failure based on the experience of more than 2 000 cases, in order to provide a reference for improving the success rate of puncture and promoting the application of distal transradial artery approach.
