Distal Radial Access: Consensus Report of the First Korea-Europe Transradial Intervention Meeting

Among patients undergoing percutaneous coronary procedures, transradial access, compared with transfemoral access, is associated with a reduced risk for complications including mortality, especially in higher risk patients. However, transradial access is limited by radial artery occlusion (RAO) that despite being mostly asymptomatic because of the extensive anastomoses between the forearm arteries restricts future use of the same radial artery. Distal radial access (DRA) in the anatomic snuffbox or on the dorsum of the hand has recently gained global popularity as an alternative access route for vascular procedures. A strong anatomic and physiological rationale yields potential for significantly reduced risk for RAO and positive impact on procedural outcome for better patient care. Indeed, currently published studies buttress very low rates of RAO after DRA, hence supporting its development. The authors provide an analysis of the foundation of DRA, provide historical background, and offer a critical review of its current status and future directions. Also, given the limited evidence currently available to properly perform DRA in the real world, consensus opinion on what is considered optimal practice is also presented to supplement this document and enhance the implementation of DRA while minimizing its complications.
