Brief Summary

Radial access is recommended as the standard approach for coronary angiography (CAG) and percutaneous coronary intervention (PCI) based on the evidence in which RA reduced mortality and bleeding events compared with femoral access. Recently, the use of distal radial artery (DRA) is rapidly increasing in accordance with the publication of several studies that have shown easy hemostasis, reduced bleeding complications and low arterial occlusion rate via distal radial approach. However, the diameter of DRA is relatively smaller than radial artery (RA) which can limit the widespread use of this access route. Regarding the size discrepancy, there is a lack of evidence to guide which patients are acceptable or not for CAG and PCI. Therefore, the main purpose of this study was to provide the reference diameter of DRA using ultrasonography in Korean patients. The clinical predictors for small DRA also were evaluated.
