PURPOSE: To determine the number of retrievable IVC filters placed and retrieval success rate between 2013 and 2014 at a tertiary center. We also examined if filters were indicated as a treatment for VTE, and whether the correct filter was selected based on 2012 ACCP guidelines.
METHODS: A list of all IVC filters successfully placed by the Interventional Radiology between 2013 and 2014 was compiled using medical records. Chart review of health records was performed to collect data patient demographics, device information, contraindications to anticoagulation, follow-up and filter retrieval attempt. Each case was reviewed by a two separate investigators using ACCP guidelines for treatment of VTE to determine if the placement of a filter and type was appropriate.
RESULTS: Total of 161 IVC filters were placed between 2013-2014. 92 of the filters were permanent (57%), and 69 were retrievable (43%). Common indications for filter placement were active bleeding (54%), DVT prophylaxis (10%), recent or planned surgery (8%), history or risk of bleeding (8%), fall risk (8%), and others (20%). 11/161 filters (15%) were not indicated. In 74 /150 (49%) an appropriate filter was placed while an inappropriate filter was placed in 76/150 (51%) cases. 69 retrievable filters placed, 9 patients died before discharge. Retrieval was attempted in 10 of the remaining 60 cases, of which 9 (15%) were successful.
CONCLUSIONS: The rate of retrievable IVC filter placements, and their retrieval, is similar to reported averages.
CLINICAL IMPLICATIONS: Some institutions have improved their filter retrieval rate through establishing IR or Pulmonary embolism clinics. We aim to establish a resident and patient education program to improve our filter placement and retrieval rates. We aim to provide a standard education sheet to patients that explain the rationale of filter placement and emphasize follow up for removal when indicated
