“…36 Thrombus can form in veins not filtered by the device including the renal veins and ovarian veins. 39 There should be minimal thrombus in the filter prior to removal based on a CT venogram. 37 Retrospective analysis has actually shown an increased rate of DVT formation from 5.2% to 20.4% with the use of IVCFs.…”

Venous thromboembolic disease (VTE) increases the risk of mortality in trauma patients. To decrease the occurrence of VTE, low dose anticoagulants are commonly prescribed. This may be unacceptable in trauma patients who have a high risk of bleeding. Inferior vena cava (IVC) filters can be employed as an alternative strategy to decrease the risk of pulmonary embolism (PE). Insertion of an IVC filter is an invasive procedure that has a range of complications. The benefits of IVC filter insertion must be compared to its risk of complications in each individual patient. A search of the literature since 2005 was conducted on MEDLINE, Evidence-Based Medicine Reviews, Cochrane Central Register of Controlled Trials and Embase. The clinical question posed was does prophylactic IVC filter insertion decrease the risk of PE in trauma patients? The available evidence was low level and unable to definitively answer this question. The majority of articles infer that IVC filter insertion is safe and may decrease the risk of PE. However, there is a need for well-designed randomised controlled trials to be conducted in this area.

“…The longer the filter is in situ, the more risk the filter will be unable to be retrieved. 39 There should be minimal thrombus in the filter prior to removal based on a CT venogram. 40 A duplex of lower limb vessels may also be appropriate prior to removal especially if clinical symptoms of DVT.…”

“…Inferior vena cava (IVC) filter, which is inserted inside a large abdominal vein to trap large clot fragments and prevent them from traveling to the heart and lungs, can prevent life-threatening venous thromboembolism, including deep vein thrombosis and pulmonary embolism (PE) [1,2]. Approximately 350,000 to 600,000 people each year in the United States (US) are affected by blood clots, and between 100,000 and 180,000 people die of PE each year [3].…”

“…Approximately 350,000 to 600,000 people each year in the United States (US) are affected by blood clots, and between 100,000 and 180,000 people die of PE each year [3]. Even though most patients with blood clots are treated with parenteral anticoagulants, an IVC filter is indicated in cases with contraindications to anticoagulants, bleeding complications, or recurrent venous thromboembolism despite optimal anticoagulation [1,2]. …”

“…Resorbable polymers, such as poly(p-dioxanone) (PPDO), polyglactin, polyglycolic acid, poly(L-lactide), and others have been used in other implantable medical devices. These implants can function safely and effectively during their required duration and then simply be absorbed into the body through hydrolysis, thereby avoiding costly removal procedures and downstream complications [1]. …”

Purpose: To determine the feasibility of infusing resorbable inferior vena cava (IVC) filter with iodine-based contrast agents to produce a radiopaque, computed tomography (CT)-visible IVC filter. Materials and Methods: Infused poly(p-dioxanone) (PPDO) was obtained by incubating PPDO in different concentrations of 4-iodobenzoyl chloride (IBC) and 2,3,5-triiodobenzoic acid (TIBA). Characterizations of infused and nascent PPDO were done using elemental analysis, micro-CT, tensile strength analysis, scanning electron microscopy, and differential scanning calorimetry. Results: Elemental analysis showed percentage loading of 1.07 ± 0.08 for IBC and 0.73 ± 0.01 for TIBA. Micro-CT images showed increased attenuation of the infused PPDO compared with the nascent PPDO. The Hounsfield unit values for infused and nascent sutures were 110 ± 40 and 153 ± 53 for PPDO infused with 2mg/mL IBC and TIBA, respectively, but only 11.35 ± 2 for nascent PPDO. In contrast the HU for bone was 116 ± 37. Tensile strength analysis showed maximum loads of 1.01 ± 0.43 kg and 10.02 ± 0.54 kg for IBC and TIBA, respectively, and 10.10 ± 0.64 kg for nascent PPDO. Scanning electron microscopy showed that the morphology of the PPDO surface did not change after coating. Conclusion: PPDO infused with a contrast agent is significantly more radiopaque than nascent PPDO on micro-CT imaging. This radiopacity could allow the position and integrity of infused resorbable IVC filter to be monitored while it is in place, increasing its safety and efficacy as a medical device.

Inferior Vena Cava Filters: Indications, Outcomes, and Evidence

Filter technology seems relatively stable, although absorbable devices are an area of investigational interest. The indications for filter placement remain controversial, with wide variations in adherence to guidelines, and relatively poor quality of data about the specific prophylactic indications of trauma or bariatric surgery. The outcomes of filters are not well-defined despite widespread clinical use, and good data remains difficult to obtain. Several larger database and institutional retrospective studies support the notions that while filters prevent pulmonary embolism, they may be associated with venous thrombotic complications. Some subsets of cancer patients may be at increased risk of these complications, but whether the filter or the underlying hypercoagulable state is the cause is not clear. Lastly, although the benefits of filter retrieval are widely assumed (but not proven), filter retrieval rates remain lower than expected. The single most influential factor in improving filter retrieval rates is dedicated follow-up with intent to retrieve the filter.
