Background: Inferior vena cava (IVC) filter placement still plays an essential role in preventing pulmonary embolism (PE) in patients with contraindications to anticoagulant therapy. However, IVC filter placement does have long-term risks which may be mitigated by retrieving them as soon as clinically acceptable. A dedicated IVC filter clinic provides a potential means of assuring adequate follow-up and retrieval. Aim: To assess the efficacy of our Inferior vena cava (IVC) filter retrieval clinic at improving the rate of patient follow-up, effective filter management, and retrieval rates. Materials and Methods: During the period of August 2017 through July 2018, 70 IVC filters were placed at our institution, and these patients were automatically enrolled into our IVC filter retrieval clinic for quarterly follow-up. We retrospectively reviewed data including appropriateness for removal at 3 months, overall retrieval rates, removal technique(s) employed, and technical success. Results: 62.9% of the potentially retrievable filters were removed during the study period. The technical success of extraction, using a combination of standard and advanced techniques, was 91.7%. Overall, 15% of the patients were lost to follow-up. Conclusion: Our findings add to the growing body of literature to support the need for a robust IVC filter retrieval clinic to ensure adequate follow-up and timely retrieval of IVC filters.
