Summary
The retrievable inferior vena cava (IVC) filter, known as the SNF, is generally easy to place percutaneously. Minor technical difficulties occurred during placement, but modifications to the insertion procedure can help circumvent these issues.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- Inferior vena cava (IVC) filters are crucial for preventing pulmonary embolism.
- The retrievable SNF device is a newer option for IVC filtration.
Purpose of the Study:
- To evaluate the ease of percutaneous placement of the SNF IVC filter.
- To identify and address technical difficulties encountered during SNF implantation.
Main Methods:
- Retrospective review of SNF filter placements.
- Analysis of procedural steps and any encountered technical challenges.
Main Results:
- The SNF filter was confirmed as generally easy to place percutaneously.
- Minor procedural difficulties were noted in most cases.
- One significant complication required a second filter placement.
Conclusions:
- The SNF IVC filter is largely straightforward to implant.
- Awareness of potential technical issues and implementation of modified procedures are recommended for optimal outcomes.
