Predictors of Transradial Cerebral Angiography Failure and Comparative Outcomes with the Transfemoral Approach: A Single-Center, 5-Year Retrospective Study

TRCA holds promise as a standard approach in neurointervention, but proficiency in both TRCA and TFCA remains essential. Radial artery issues and prolonged procedure time are significant predictors of TRCA failure. Optimizing TRCA outcomes requires meticulous preprocedural aortic arch evaluation, enhanced operator experience, and continuous technical refinements.
