“…Long-dwelling IVC filters are associated with higher complication rates. 2 Long dwell times (>6 months) are a risk factor for failure of standard retrieval techniques 3,4 and are associated with high rates of the need to use adjunctive techniques for retrieval 3 which is likely secondary to incorporation of device in the caval wall, IVC thrombosis and penetration of the caval wall. 5 Furthermore, long-dwell IVC filters have a higher rate of retrieval complications.…”

“…It is postulated that long-dwell filters may have a slightly increased risk of complications based on published studies that suggest retrievability becomes more difficult with dwell time longer than 6 months. 3,4 Leaving the filter in situ permanently was a consideration for this patient however given their young age, lack of long-term data for in situ retrievable IVC filters and high retrievability rates for long-dwell filters, a decision was made for an attempt at retrieval. The potential risks of non-retrieval versus retrieval were discussed in the informed consent process, the risks are summarised in Table 1.…”

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. Longdwelling 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 longestdescribed successful retrieval of a Cook Celect IVC filter at 5,117 days.

“…Filters with an embedded hook or that tilted >15° have been associated with 129 and up to 33 times higher risk of difficult retrieval, respectively ( 41 , 56 ). In a study by Desai et al ( 57 ), when filters were carried for more than 210 days, advanced retrieval techniques were needed in over 40% of the cases.…”

Mortality rates associated with venous thromboembolism (VTE) are high. Inferior vena cava filters (IVCFs) have been frequently placed for these patients as part of their treatment, albeit the paucity of data showing their ultimate efficacy and potential risk of complications. Issues regarding long-term filter dwell time are accounted for in society guidelines. This topic has led to an FDA mandate for filter retrieved as soon as protection from pulmonary embolism is no longer needed. However, even though most are retrievable, some were inadvertently left as permanent, which carries an incremental lifetime risk to the patient. In the past decade, attempts have aimed to determine the optimal time interval during which filter needs to be removed. In addition, distinct strategies have been implemented to boost retrieval rates. This review discusses current conflicts in indications, the not uncommon complications, the rationale and need for timely retrieval, and different quality improvement strategies to fulfill this aim.

“…It soon became apparent that rIVCFs also were not without risk, especially those with long dwell times. 13 New filter designs now allow for conversion to IVC stents. These designs include the VenaTech Convertible (B. Braun Medical, Germany) and Sentry filters (Boston Scientific).…”

Inferior vena cava filters are an important therapeutic option for patients with venous thromboembolism and contraindication to anticoagulation. Indications for filter placement have varied over the previous decades. This article discusses the history of inferior vena cava filter use, with a basic overview of technology and specific devices. Finally, this article reviews emerging filter design and technology. Understanding the basics of inferior vena cava filters is critical to building more robust clinical data for the purpose of improving patient outcomes.
