Titanium Greenfield R Vena Cava Filter W Hooks

FDA-Cleared Indications

• Prevention of recurrent pulmonary embolism in patients who cannot be adequately managed with anticoagulant therapy.
• Use in patients with venous thromboembolism who have a contraindication to anticoagulation.

Clinical Applications

• Placement in the inferior vena cava to reduce the risk of recurrent pulmonary embolism.
• Treatment of patients with deep vein thrombosis when anticoagulation cannot be used.
• Treatment of patients with pulmonary embolism when anticoagulation is contraindicated or inadequate.
• Permanent IVC filter placement using fluoroscopic imaging and an appropriate delivery system.

Reported off-label uses

• Prophylactic placement in selected trauma or surgical patients who have a high risk of pulmonary embolism but do not have documented venous thromboembolism.
• Use in selected patients with recurrent pulmonary embolism despite therapeutic anticoagulation.

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Practical Considerations

• The filter is available in different sizes; the selected size must match the diameter and anatomy of the IVC.
• Placement requires imaging guidance, typically fluoroscopy, to confirm the IVC anatomy, filter position, and deployment.
• The device has hooks intended to secure it in the IVC and is generally considered a permanent filter; removal may not be feasible or intended.
• Potential complications include filter migration, tilt, fracture, penetration of the IVC wall, thrombosis, and recurrent or new pulmonary embolism.
• MRI compatibility and conditions should be confirmed from the applicable device labeling before MRI. Active infection, anatomic abnormalities, or inability to access the IVC may affect suitability.
