Abstract
Abstract Background/Introduction Postprocedural radial artery occlusion (RAO) is still the Achilles' heel of conventional transradial approach (cTRA) as it limits its reuse for future coronary procedures. A distal transradial access (dTRA) via the anatomical snuffbox has been proposed as an alternative. It is hypothesised that dTRA may reduce the incidence of RAO. Purpose To assess whether routine dTRA reduce the risk of RAO in consecutive patients undergoing coronary angiography or intervention, in comparison with cTRA. Methods Out of 465 subjects, 400 patients were included in a prospective, single-center, randomized (1:1) study. Hemodynamic instability, ST-elevation myocardial infarction, forearm artery occlusion or prior radial access failure were the exclusion criteria. Ultrasound-guided follow-up was obtained after 1 day and 60 days to evaluate the incidence of acute and late RAO. Results Baseline characteristics of patients were matched. Results are presented in table 1. Conclusion(s) The incidence of postprocedural acute and late RAO after routine dTRA and cTRA is low and occur with similar frequency when evaluated by ultrasound.
