Best Practices for the Prevention of Radial Artery Occlusion After Transradial Diagnostic Angiography and Intervention: An International Consensus Paper

Transradial access (TRA) is increasingly used worldwide for percutaneous interventional procedures and associated with lower bleeding and vascular complications than transfemoral artery access. Radial artery occlusion (RAO) is the most frequent post-procedural complication of TRA, restricting the use of the same radial artery for future procedures and as a conduit for coronary artery bypass graft. The authors review recent advances in the prevention of RAO following percutaneous TRA diagnostic or interventional procedures. Based on the available data, the authors provide easily applicable and effective recommendations to prevent periprocedural RAO and maximize the chances of access in case of repeat catheterization or coronary artery bypass grafting surgery.
