Summary
A novel percutaneous inferior vena cava filter demonstrated good tolerability in 15 patients over 13 months. While effective, one patient experienced recurrent embolism, and local thrombogenicity occurred in two, suggesting short-term heparinization is advisable.
Area of Science:
- Vascular Surgery
- Medical Devices
- Interventional Radiology
Background:
- Inferior vena cava (IVC) filters are crucial for preventing pulmonary embolism in high-risk patients.
- Development of new IVC filters aims to improve safety, efficacy, and retrieval options.
- Percutaneous insertion and retrieval offer less invasive treatment strategies.
Purpose of the Study:
- To evaluate the safety and efficacy of a new stainless steel helical basket IVC filter.
- To assess the feasibility of percutaneous insertion and retrieval.
- To determine the short-term outcomes and potential complications.
Main Methods:
- A prospective study involving 15 patients requiring IVC filtration.
- The new filter was inserted percutaneously via a 10F catheter (antegrade or retrograde).
- Follow-up included clinical assessment for complications and imaging up to 13 months.
Main Results:
- The filter was well tolerated in most patients during the follow-up period.
- One patient experienced a fatal recurrent pulmonary embolism despite filter placement.
- Two patients developed local thrombogenicity; no other significant side effects were reported.
Conclusions:
- The new percutaneous IVC filter shows promise with good short-term tolerability.
- Heparinization post-insertion is recommended to mitigate thrombogenicity risks.
- Further evaluation, including heparin-coated filter options, is warranted.
