This chapter analyzes randomized controlled trials (RCTs) comparing distal radial access (DRA) with conventional transradial access (TRA), with a focus on key outcomes: forearm radial artery occlusion (RAO), access site crossover, radial artery spasm (RAS), and hemostasis time. The results demonstrate important benefits of DRA, particularly in significantly reducing the risk of forearm RAO. However, they also underscore the complexities associated with DRA. The chapter also addresses the technical challenges associated with DRA. In addition, it examines the impact of DRA on procedural outcomes and highlights the post-procedural benefits of DR. Finally, remaining evidence gaps from RCTs are outlined.

摘要

This chapter analyzes randomized controlled trials (RCTs) comparing distal radial access (DRA) with conventional transradial access (TRA), with a focus on key outcomes: forearm radial artery occlusion (RAO), access site crossover, radial artery spasm (RAS), and hemostasis time. The results demonstrate important benefits of DRA, particularly in significantly reducing the risk of forearm RAO. However, they also underscore the complexities associated with DRA. The chapter also addresses the technical challenges associated with DRA. In addition, it examines the impact of DRA on procedural outcomes and highlights the post-procedural benefits of DR. Finally, remaining evidence gaps from RCTs are outlined.
