Bidirectional loop-snare technique for adherent inferior vena cava filter retrieval

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Device Technology

Background:

• Inferior Vena Cava (IVC) filters prevent pulmonary embolism in patients contraindicated for anticoagulation.
• Retrieval of IVC filters can become challenging with increased indwelling duration.
• The Günther Tulip IVC Filter™ is a commonly used device requiring effective retrieval methods.

Observation:

• A novel bidirectional loop-snare technique (BLT) was developed for IVC filter retrieval.
• The BLT utilizes simultaneous jugular and femoral snare access.
• The jugular snare secures the filter hook, while the femoral snare addresses leg adhesion.

Findings:

• The BLT method facilitates easier retrieval of the Günther Tulip IVC Filter™.
• Simultaneous bidirectional pulling increases retrieval power.
• Successful IVC filter retrieval was achieved using the BLT approach.

Implications:

• The BLT offers a simpler and more effective solution for difficult IVC filter retrievals.
• This technique may reduce complications associated with prolonged IVC filter indwelling.
• Improved IVC filter retrieval methods enhance patient safety and treatment outcomes.
