Transradial approach (TRA) for cardiac catheterization and percutaneous coronary interventions (PCI) is increasingly being used worldwide in both elective and emergency procedures because it reduces net adverse clinical events, through a reduction in major bleeding and all-cause mortality, when compared to transfemoral approach. However, radial artery occlusion (RAO) after the procedure (the incidence of which varies from 1% to 10%) remains one of the major limitations of TRA.
