Summary
Percutaneous caval filter placement is preferred over surgical methods for venous thromboembolic disease due to lower complication rates. Further research is needed to identify the optimal device for this minimally invasive procedure.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Cardiovascular Medicine
Background:
- Percutaneous caval filter placement is increasingly used for venous thromboembolic disease.
- Both surgical and percutaneous approaches exist, with various devices available.
- Existing studies have limitations in comparing device efficacy due to differing criteria.
Purpose of the Study:
- To analyze data on caval filter characteristics, availability, and clinical outcomes.
- To compare percutaneous versus surgical filter placement.
- To guide the selection of appropriate caval filter devices.
Main Methods:
- Review of published and unpublished data on caval filters.
- Analysis of physical characteristics, clinical availability, morbidity, mortality, and efficacy.
- Comparison of percutaneous and surgical placement techniques.
Main Results:
- Percutaneous filter placement demonstrates lower morbidity and mortality rates compared to surgical placement.
- Current data is insufficient to determine an ideal caval filter device.
- Device selection may depend on clinical context and specific filter attributes.
Conclusions:
- Percutaneous placement of caval filters is recommended over surgical placement.
- Further independent, multicenter, prospective, randomized trials are essential.
- A mandatory registry for all caval filter recipients is advised to improve data quality.
