Summary
Knotting a catheter during angiography is rare but can be managed without surgery. A novel technique uses a second, rigid J-tipped catheter to safely untie the knot under fluoroscopic guidance.
Area of Science:
- Interventional Cardiology
- Medical Device Technology
Background:
- Catheter knotting, though infrequent, poses a significant complication during angiographic procedures.
- Prompt identification and non-surgical resolution are crucial to prevent adverse patient outcomes and surgical intervention.
Observation:
- A unique case of distal angiographic catheter knot formation was encountered.
- The knot required a specialized technique for untying, highlighting the need for innovative solutions.
Findings:
- A novel technique for non-surgical catheter knot untying is presented.
- This method involves utilizing a more rigid, J-shaped catheter inserted via the contralateral femoral artery.
- Direct fluoroscopic visualization with image magnification is essential for successful execution.
Implications:
- This technique offers a viable alternative to surgical intervention for catheter knot complications.
- It enhances the safety and efficacy of interventional procedures by providing a method to manage device-related issues.
- The described approach can potentially reduce procedure time and healthcare costs associated with surgical management.
