Why the study?
Long-dwelling IVC filters are associated with higher complication rates, increased retrieval difficulty, and more retrieval complications once PE prophylaxis is no longer needed.
This case report demonstrates the feasibility of retrieving a Cook Celect IVC filter even after an extremely prolonged dwell time of over 14 years using advanced snare techniques.
May support retrieval of long-dwelling IVC filters with planning; hypothesis-generating, needs prospective validation.
Inferior vena cava (IVC) filters are used in certain patients to help prevent the occurrence of pulmonary embolism (PE). IVC filters are generally recommended to be removed once PE prophylaxis is no longer required. Long-dwelling IVC filters are associated with higher complication rates (Vasa 2020; 49: 449), being more difficult to retrieve and associated with higher retrieval complications (Cardiovasc Diagn Ther 2016; 6: 632). This report describes the pre-procedural work-up and removal of an IVC filter with a prolonged dwell time of 5,117 days (14 years, 3 days) using the loop snare advanced retrieval technique. As far as the authors are aware this case is the longest-described successful retrieval of a Cook Celect IVC filter at 5,117 days.
