Inferior vena cava filter retrievals using advanced techniques: a systematic review

ollowing a 1998 clinical trial that demonstrated the short-term efficacy of inferior vena cava (IVC) filters in preventing pulmonary embolism (PE), the implantation rate of IVC filters increased for years before peaking in 2010. These filters are not always intended for permanent use, and in 2010, the US Food and Drug Administration recommended the removal of retrievable IVC filters that were no longer required, reinforcing this recommendation in 2014. Although Brown et al. Many factors may contribute to low retrieval rates, including the difficulty of removing filters. Ray et al. Reported causes for standard retrieval failures include tilted, damaged, or thrombosed filters. rthermore, not all patients are closely followed up after filter placement, leading to longer dwell times before an attempted retrieval and increased technical complexity during retrieval. In a study of patients with a mean dwell time of 685 days, 60% were referred for ABSTRACT This study aimed to assess the safety of complex inferior vena cava (IVC) filter retrieval techniques through a systematic review of published literature.
