Severe catheter kinking and entrapment during transradial coronary angiography: percutaneous retrieval using a...

Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• The transradial (TR) approach is favored for coronary angiography and intervention due to reduced bleeding and vascular complications.
• Aggressive catheter manipulation in tortuous anatomy during TR procedures can cause catheter kinking and entrapment.
• Existing percutaneous retrieval techniques involve homolateral radial or femoral access.

Observation:

• This study introduces a novel rescue technique for managing entrapped catheters during transradial procedures.
• The technique utilizes a sheathless guide catheter to overcome catheter kinking and entrapment.

Findings:

• The sheathless guide catheter was successfully employed to retrieve a severely kinked and entrapped diagnostic catheter.
• This represents the first documented use of a sheathless guide catheter for this specific complication in transradial access.

Implications:

• This technique offers a potentially simpler and effective solution for catheter entrapment during transradial interventions.
• It may reduce procedure time and the need for alternative, more invasive retrieval methods.
• Further research could explore the broader applicability and success rates of this sheathless guide catheter rescue technique.
