Disease relevance of Vena Cava Filters

• A prospective clinical study is needed to determine the efficacy of filter use among patients with pulmonary embolism who do not meet strict guidelines for insertion of a vena cava filter [1].
• Patients with secondary VTE, natural inhibitor deficiencies, lupus anticoagulant, cancer, long-term antithrombotic therapy, vena cava filters, or pregnancy were excluded [2].
• Recurrent thromboembolism in patients with vena cava filters [3].
• PURPOSE: Venacavograms are routinely obtained before vena cava filter placement to evaluate cava size, patency, and the presence of thrombus or venous anomalies [4].
• The risk of pulmonary embolus was reduced by the use of a retrievable vena cava filter in one patient and thrombolytic therapy in the presence of a previously inserted cava filter in the other two [5].

High impact information on Vena Cava Filters

• The use of prophylactic vena cava filters should be re-examined [6].
• CONCLUSIONS: Insertion of a vena cava filter was not associated with a significant reduction in the 1-year incidence of rehospitalization for pulmonary embolism [1].
• PURPOSE: To evaluate the Gunther Tulip vena cava filter with regard to ease of placement, complications, and retrieval over long time periods [7].
• In this study we investigated the magnetic resonance (MR) imaging properties of a Nitinol vena cava filter, in various anatomic and angiographic scans, as well as the feasibility of placing this filter under near real-time, high-resolution MR fluoroscopy [8].
• Prophylactic vena cava filter insertion in patients with traumatic spinal cord injury: preliminary results [9].

Chemical compound and disease context of Vena Cava Filters

• These include the need to screen for malignancy in idiopathic DVT, a high index of suspicion for venous thrombosis in the cancer patient, the use of vena cava filters, and the anti-neoplastic effects of heparin [10].

Biological context of Vena Cava Filters

• Günther Tulip Retrievable Vena Cava Filter: results from the Registry of the Canadian Interventional Radiology Association [11].

Anatomical context of Vena Cava Filters

• A guide wire snare was used to facilitate passage of a Mobin-Uddin vena cava filter through a tortuous left innominate vein, and a Kimray-Greenfield vena cave filter from the suprarenal into the infrarenal position of the inferior vena cava [12].
• Avoiding renal vein entry when implanting the Mobin-Uddin vena cava umbrella filter [13].
• Percutaneous retrieval of a vena cava filter from the right atrium: case report [14].
• A case of an embolization of an Anthéor vena cava filter into the pulmonary artery with disastrous exit 9 days after placement is described [15].
• An unusual cause of upper gastrointestinal haemorrhage--perforation of a vena cava filter into the duodenum [16].

Associations of Vena Cava Filters with chemical compounds

• We believe that percutaneous insertion of vena cava filters should not replace anticoagulation in routine proximal DVT, and those patients who require an inferior vena cava filter for failure of anticoagulation should continue to receive heparin to treat the primary thrombotic process [17].
• Successful retrieval of a titanium Greenfield vena cava filter embedded within its introducer sheath [18].
• To assess the trapping efficiency of two vena cava filters, 326 radiopaque thrombi 5 mm in diameter were injected into adult sheep: four with LG-Medical (LGM) and four with titanium Greenfield (TG) filters [19].
• The Vascor umbrella filter is a two-stage stainless-steel device with attachment tabs for anchoring and centering [20].

Gene context of Vena Cava Filters

• Use of vena cava filters in pediatric trauma patients: data from the National Trauma Data Bank [21].

Analytical, diagnostic and therapeutic context of Vena Cava Filters

• The authors present a removable vena cava filter that may be introduced percutaneously, is atraumatic to the venous wall, and permits the simultaneous use of thrombolytic therapy [22].
• CONCLUSION: Duplex ultrasonography is a useful and accurate method for assessment of the IVC before vena cava filter placement [4].
• Our objective was to evaluate the safety and accuracy of a bedside technique for placing vena cava filters with intravascular ultrasonography [23].
• Through an innovative electron microscopy technique, thrombi and fibrotic tissue taken from 14 explanted vena cava filters were observed [24].
• Venography and vena cava filters [25].
