Vena Cava Filter Occlusion and Venous Thromboembolism Risk in Persistently Anticoagulated Patients

If therapeutic anticoagulation can be safely begun in patients with IVC filters inserted after venous thromboembolism, further management with clinical surveillance, including ultrasound examination of the IVC filter and graded degrees of anticoagulation therapy if filter clot is detected, has a favorable prognosis. This approach appears valid for patients with current IVC filter and can serve as a comparison standard in subsequent clinical trials to optimize clinical management of these patients.
