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.

Treatment and study plan

Distal radial artery approach

Procedure

Use of distal radial artery approach in coronary angiography and angioplasty

Primary outcomes

  1. The primary endpoint of our study is to compare the efficacy of the distal and proximal transradial approaches in terms of RAO incidence.

    Time frame: The RAO will be evaluated 24 hours after the procedure by ultrasound examination and was defined as the absence of both color pattern and pulsed wave registry.

    The primary endpoint of our study is to compare the efficacy of the distal and proximal transradial approaches in terms of RAO incidence.
