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.
下腔静脉（IVC）滤器用于某些患者，以帮助预防肺栓塞（PE）的发生。一般建议在不再需要预防PE时取出IVC滤器。长期留置的IVC滤器与更高的并发症发生率相关（《血管》2020年；49：449），更难取出且与更高的取出并发症相关（《心血管诊断与治疗》2016年；6：632）。本报告描述了使用圈套器高级取出技术对一个留置时间长达5117天（14年零3天）的IVC滤器进行术前检查和取出的过程。据作者所知，该病例是Cook Celect IVC滤器留置5117天后成功取出的报道中时间最长的。
