why radial access
• CI of femoral Access
• Less entry site complications : 0.3% vs 2.8%
• Association kardegic plavix
• Ambulatory
• COST
• Artery:Vertébral , mésentéric , renal iliac artery
• Femoral with specific device

Conclusion
• Learning curve
• All arteries can be treated (except btk) with
specific device
• Less complication and ambulatory
