Aortic & peripheral vascular diseaseCohort study
Distal Radial Access for Radial Artery Recanalization
- Multicentre international registry study
- 7 centres
- Operators with substantial distal radial access (DRA) experience (>200 procedures)
Authors' conclusion
Recanalization of occluded radial arteries through DRA is a safe, effective, and reproducible procedure with the primary benefit to maintaining the safest vascular access option.
Study context
- Population
- Patients with radial artery occlusion
- Participants
- 110 patients · 7 centres
- Outcome
- Procedural success and radial artery patency
- Follow-up
- 31 (30-32) days
Main finding
As reported in the abstract
Procedural success
94% (95% CI: 88%-97%)
Radial artery patency at 30 days
80% (95% CI: 72%-86%)
Observational data: associations, not effects.
