Biopsy Forceps-Assisted Loop Snare Technique for Complex Retrieval of Inferior Vena Cava Filter

Area of Science:

• Interventional Radiology
• Vascular Surgery

Background:

• Retrieving inferior vena cava (IVC) filters can be challenging due to severe tilt and embedded hooks.
• Embedded hooks pose a significant obstacle to standard IVC filter removal procedures.

Purpose of the Study:

• To present a novel technique for retrieving IVC filters with embedded hooks.
• To address limitations of standard retrieval methods for complex IVC filter cases.

Main Methods:

• A biopsy forceps was utilized to reshape the embedded filter hook.
• The forceps repositioned the hook to the central position for easier release from the caval wall.
• A loop snare was employed in conjunction with the biopsy forceps.

Main Results:

• The biopsy forceps-assisted loop snare technique successfully retrieved IVC filters with embedded hooks.
• This method effectively released hooks lodged in the caval wall.

Conclusions:

• The biopsy forceps-assisted loop snare technique provides a new solution for complex IVC filter retrieval.
• This technique is a valuable option when conventional retrieval methods are unsuccessful.
