Transradial arterial access catheter knots: towards a new treatment algorithm

Area of Science:

• Interventional Cardiology
• Vascular Access Techniques

Background:

• Transradial access is increasingly preferred for percutaneous coronary and non-coronary interventions due to improved patient outcomes.
• Compared to the transfemoral approach, transradial access is associated with reduced bleeding, fewer vascular events, and shorter hospital stays.

Purpose of the Study:

• This review aims to consolidate current knowledge on preventing and managing catheter kinking during transradial interventions.
• To provide evidence-based strategies for resolving radial access catheter knot complications.

Main Methods:

• Literature review of studies and case reports on transradial access complications.
• Analysis of techniques for catheter manipulation and knot prevention.
• Synthesis of clinical evidence regarding radial access catheter knot management.

Main Results:

• Catheter kinking is a recognized complication of transradial access, requiring specific management strategies.
• Various techniques exist to prevent and resolve catheter knots, ensuring procedural success.
• Early recognition and appropriate intervention are crucial for mitigating risks associated with catheter kinking.

Conclusions:

• Transradial access is a safe and effective method for cardiovascular interventions, but awareness of potential complications like catheter kinking is essential.
• Effective strategies for preventing and resolving catheter knots can optimize patient safety and procedural outcomes.
• Further research may refine techniques for managing radial access catheter complications.
