Abstract
Objectives
This study aimed to determine the incidence of radial artery anomalies in a large cohort of patients undergoing TRA and to evaluate their specific impact as predictors of procedural failure and access site complications.
Methods
This prospective, observational, single-center study enrolled 1000 consecutive patients undergoing coronary angiography or intervention via TRA between 2022 and 2024. Radial artery anatomy was assessed using retrograde radial arteriography immediately following sheath insertion. Anatomical variants were categorized into high bifurcation (origin proximal to the cubital fossa), Radial artery loops (full 360-degree curvature), Tortuosity (curve of more than 45 degrees in the vessel), Narrow calliber, Spasm, and Ulnar absent. Procedural success was defined by completion of the procedure via the initial radial access site. Binary logistic regression was used to identify independent predictors of procedural failure (crossover to alternate access).
