Grasp-and-Fold Technique for Complex Inferior Vena Cava Filter Retrieval.

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Medical Device Retrieval

Background:

• Inferior vena cava (IVC) filters are crucial for preventing pulmonary embolism.
• Retrieval of deeply embedded or distorted IVC filters presents significant challenges.
• Existing retrieval methods may be insufficient for complex filter configurations.

Purpose of the Study:

• To evaluate the efficacy and safety of the grasp-and-fold technique for retrieving complex IVC filters.
• To assess the feasibility of using endobronchial forceps for filter manipulation.
• To determine the rate of successful retrieval and associated adverse events.

Main Methods:

• Retrospective analysis of 14 patients with embedded or distorted IVC filters.
• Application of the grasp-and-fold technique using endobronchial forceps.
• Assessment of procedural success and adverse events.

Main Results:

• Successful retrieval of all 14 inferior vena cava (IVC) filters.
• No severe adverse events were reported; mild and moderate events occurred.
• One patient had pre-existing retained filter struts.

Conclusions:

• The grasp-and-fold technique is a viable option for complex IVC filter retrieval.
• This method offers a solution for filters with inaccessible tips.
• Further research in larger cohorts is warranted to confirm safety and efficacy.
