Purpose: To determine practice patterns of inferior vena cava filters (IVCFs), retrieval rates, and reasons why retrievable-IVCFs (R-IVCFs) are kept permanent.
Methods: A total of 399 patients who received IVCFs at Third Hospital of Hebei Medical University from January 2017 to December 2017 were registered and retrospectively studied. Date of demographics, baseline medical history, dwell time, reasons why R-IVCFs were kept permanent, and R-IVCFs thrombus were collected.
Results: A total of 399 IVCFs were placed during the study period including 27 permanent IVCFs and 372 R-IVCFs. Among all patients who received R-IVCFs, the mean dwell time was 18.25 ± 16.60 days, follow-up rate was 96.24% (358/372), and 337 R-IVCFs were attempted to be removed. Except one, 336 R-IVCFs were retrieved successfully (336/372, 90.32%). Sixty-four R-IVCFs thrombi were found during retrieval including 53 small-size thrombi (< 1 cm × 1 cm) and 13 large-size thrombi (>1 cm × 1 cm). Fifty-three R-IVCFs with small-size thrombi were removed successfully with no additional treatments. Twelve large-size thrombi were retrieved successfully after catheter-directed thrombolysis.
Conclusions: With good follow-up, the retrieval rate could be improved to 90.32%. The main reasons why R-IVCFs were kept permanent were to avoid losing follow-up and overcome inappropriate selections of indications or IVCF types. And R-IVCFs with thrombus could be removed safely.

Background: It is recommended to remove retrievable inferior vena cava filters (r-IVCFs) when they are no longer needed because their presence may give rise to serious complications related to prolonged placement of the filter. An advanced filter retrieval technique may help improve the retrieval rate.
Methods and results: 107 consecutive patients (mean age; 61±18 years, male 53%) in whom r-IVCF retrieval was attempted were prospectively enrolled between April 2012 and December 2018.

Objective: Poor retrieval rates for retrievable inferior vena cava filters (R-IVCFs) have been reported throughout the literature, with poor follow-up a common cause. In 2009, we reported a retrieval rate of 18% despite an initial follow-up rate of 85%. Use of a registry has been shown to improve retrieval rates.

The American Association for the Surgery of Trauma challenged the trauma community to improve a 22 per cent average removal rate for retrievable inferior vena cava filters (r-IVCFs). Since 2006, we maintained a "filter registry" documenting all IVCFs placed in trauma patients. Our goal was to improve removal rates for r-IVCF.

We present the case of a patient with retrievable inferior vena cava (IVC) filter-related pseudoaneurysms of the infrarenal aorta and right renal artery, with associated erosion into the duodenal wall. The patient was seen 10 months following multiorgan trauma and placement of a prophylactic retrievable IVC filter (R-IVCF). Management required autogenous aortic reconstruction, caval repair, and subsequent right nephrectomy.
