Distal Radial Artery Approach to Prevent Radial Artery Occlusion (DAPRAO)

The main complication of transradial intervention is radial artery occlusion (RAO). This is relevant because it limits the radial approach for future interventions and disables this conduit for coronary bypass grafts and arteriovenous fistula. Observational studies suggest that distal radial access could reduce RAO incidence. The primary endpoint of our study is to compare the efficacy of the distal and proximal transradial approaches in terms of RAO incidence. The safety endpoint is the incidence of complications between these two methods.
