Single access 2-snare technique: A novel approach for challenging IVC filter retrieval

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Cardiovascular Medicine

Background:

• Inferior Vena Cava (IVC) filters prevent pulmonary embolism in patients unsuitable for anticoagulation.
• Filter retrieval is crucial to avoid long-term complications, but can be difficult if embedded.
• Existing retrieval methods may have limited success with deeply embedded filters.

Observation:

• A case study details the use of a novel single access, two-snare technique for retrieving a Günther Tulip IVC filter.
• The technique involves bilateral snare insertion via the jugular vein to grasp and straighten the embedded filter.
• Successful detachment and removal of the embedded filter were achieved using this innovative approach.

Findings:

• The single access, two-snare strategy effectively addressed a complex IVC filter retrieval scenario.
• This method demonstrated the ability to dislodge and remove an embedded filter that resisted conventional techniques.
• Immediate removal from the jugular vein and successful hemostasis were achieved post-procedure.

Implications:

• This technique presents a promising new option for managing difficult IVC filter retrievals.
• It may improve success rates and reduce complications associated with embedded IVC filters.
• Further research could establish this method as a standard approach for challenging filter removals.
