Minimally invasive transradial intervention using sheathless standard guiding catheters

Area of Science:

• Cardiovascular Interventions
• Vascular Access Techniques
• Minimally Invasive Procedures

Background:

• Transradial interventions aim to enhance patient comfort and minimize access-site complications.
• Sheathless techniques may further miniaturize transradial procedures.
• Guiding catheters are approximately 2 French sizes smaller than introducer sheaths.

Observation:

• A sheathless transradial technique was evaluated using standard 5 and 6 French guiding catheters.
• Eleven patients underwent transradial interventions (coronary and renal) utilizing this technique.
• Four different methods for creating an inner dilator facilitated successful sheathless guide insertion in 10 out of 11 patients.

Findings:

• The sheathless transradial approach was successful in all attempted cases.
• No radial artery access-site complications were reported.
• No crossover to femoral access was required, indicating high procedural success and safety.

Implications:

• Sheathless transradial intervention with standard guiding catheters is a safe and effective alternative.
• This technique offers potential benefits in patient comfort and reduced complication rates.
• It provides a viable option for treating coronary and peripheral vascular lesions.
