The G2 inferior vena cava (IVC) filter demonstrated a 100% success rate for retrieval in this study. Retrieval safety was high, with no major complications observed, regardless of filter dwell time.
Area of Science:
- Medical Devices
- Interventional Radiology
- Vascular Surgery
Background:
- Inferior vena cava (IVC) filters are used to prevent pulmonary embolism (PE).
- The G2 IVC filter is one such device used for PE prophylaxis.
- Assessing the retrievability of IVC filters is crucial for patient safety and effective treatment.
Purpose of the Study:
- To evaluate the retrievability of the G2 IVC filter.
- To identify factors influencing the safety and technical success of G2 IVC filter retrieval.
- To determine complication rates associated with G2 IVC filter removal.
Main Methods:
- Retrospective analysis of 27 G2 IVC filter removals in 26 patients between October 2006 and June 2008.
- Patients received filters for PE prophylaxis due to history of thromboembolic disease or high PE risk.
- Data collected included filter dwell time, technical success, and complications during retrieval.
Main Results:
- All 27 retrieval attempts (100%) were technically successful.
- No major complications such as filter thrombosis, migration, fracture, or caval occlusion were observed.
- Filter tilting occurred in 18.5% of cases, with one instance of probable filter incorporation.
Conclusions:
- G2 IVC filter retrieval is highly successful technically.
- The complication rate for G2 IVC filter retrieval is low.
- Dwell time did not appear to affect the technical success of G2 IVC filter retrieval within the studied range.
