Background: Inferior vena cava filters (IVCF) have become an important part of venous thromboembolic disease’s (VTD) therapy. IVCF are used to prevent embolization of a lower extremity deep vein thrombosis (DVT) when the risk of pulmonary embolism (PE) is high. Nevertheless, guidelines differ on the recommended indications for IVCF placement due to lacking evidence of their benefit.

Aims: To evaluate the adherence to different guidelines recommendations regarding to the indication for IVCF placement and to assess retrieval rates and their complications in a tertiary hospital.

Methods: A retrospective observational study was performed including 185 patients in which an IVCF was placed between 2015 and 2020 in a tertiary hospital of Barcelona. We considered absolute indication if it was included in all clinical guidelines revised and relative indication if it was included in some (Table 1).

Results: The main epidemiologic and clinical data of the patients are shown in Table 2. The mean age was 63.4 years (standard derivation 15), and 58.4% were men. 76.6% had an age-adjusted Charlson Comorbidity Index score equal or higher than 4. 45% of the patients had cancer. 32.4% had previous history of VTD (80% PE, 20% DVT). Regarding to filter placement indication, 70 (38%) patients had no indication, 87 (47%) had an absolute indication and 28 (15%) had a relative indication. There was an important charge of complications associated with the filter (12.4%), being the most frequent one’s instrumental failure (34.8%) and thrombosis (30.4%). IVCF was not removed in 38.9% of the patients and 17.8% of them had a VTD recurrence. The mortality rate was 55.7%.

Conclusion(s): There is an important proportion of patients in which a IVCF is placed without a strong indication, and this becomes remarkable because there is an important charge of complications associated. More than a half of the patients died during the follow-up.
