Preventing and Managing Radial Artery Occlusion following Transradial Procedures: Strategies and Considerations.

ABSTRACT

Τransradial artery access has recently gained widespread acceptance as the preferred approach for coronary angiography and interventions, due to its lower incidence of bleeding and vascular complications compared to transfemoral access. However, thrombotic occlusion of the radial artery has emerged as the most common complication of this method, impeding its use in future interventions, and in the creation of arteriovenous fistulae for hemodialysis patients, or as a graft for coronary artery bypasses grafting. In this comprehensive review, we delve into the anatomy of the radial artery, the pathophysiology and diagnosis of radial artery occlusion, the identification of potential risk factors and, finally, prevention and treatment strategies. We acknowledge that distal transradial access provides an effective alternative for coronary angiography and catheterizations, with a reduced incidence of radial artery occlusion.
