Correct!
4. There is no indication for IVC filter in the absence of a contra-indication to ongoing anticoagulation such as active bleeding.

The Antithrombotic Therapy and Prevention of Thrombosis Evidence Based Practice Guidelines recommend against the use of IVC filters for patients treated with anticoagulants (2). The Guidelines do recommend the use of IVC filters for patients with a contraindication to anticoagulation. Additionally, the guidelines recommend a conventional course of anticoagulation for patient with an initial contraindication to anticoagulation treated with IVC filters once that contraindication is resolved.

Which of the following is true regarding the role of screening for a hypercoagulable state following a venous thromboembolic event (VTE)? (Click on the correct answer to proceed to the next panel)

1. Absolutely essential as the presence of a heritable hypercoagulable state would likely change the recommend time frame for anti-coagulant therapy.
2. More important than screening for a hypercoaguable state is evaluating whether the VTE event was provoked or unprovoked.
3. Screening for a hypercoagulable state has no role in evaluating or managing patients with VTE disease including DVT and/or PE.
4. Screening is only recommended for patients with arterial not venous thromboembolic disease.
