Radial artery occlusion after transradial coronary catheterization

Area of Science:

• Cardiology
• Vascular Surgery
• Interventional Cardiology

Background:

• The transradial approach (TRA) is increasingly used for coronary angiography and interventions.
• Radial artery occlusion (RAO) is the most frequent complication, occurring in 1-10% of cases.
• RAO can preclude future transradial access and limit arterial graft options.

Purpose of the Study:

• To review predictive factors for RAO.
• To discuss recognition, prevention, and treatment of RAO.
• To provide a comprehensive overview of managing RAO after TRA.

Main Methods:

• Literature review of studies on transradial catheterization and RAO.
• Analysis of factors associated with RAO occurrence.
• Synthesis of current evidence on RAO prevention and management.

Main Results:

• RAO incidence ranges from 1% to 10%.
• While typically not causing hand ischemia, RAO has significant long-term implications.
• Various factors predict RAO, and prompt recognition is crucial.

Conclusions:

• RAO is a significant complication of TRA requiring careful management.
• Understanding predictive factors and implementing preventive measures can reduce RAO incidence.
• Effective strategies for RAO recognition and treatment are essential for patient care.
