What is a primary indication for placing an IVC filter?

• A. Minor PE
• B. Recurrent PE or high risk for developing
• C. Chronic Venous Insufficiency
• D. Peripheral Artery Disease

Answer: (B)

The placement of an inferior vena cava (IVC) filter is primarily indicated for patients who are at high risk for recurrent pulmonary embolism (PE) or those who have already experienced recurrent PE. An IVC filter serves as a preventive measure, capturing thrombi (blood clots) that may dislodge from the lower extremities to prevent them from reaching the lungs, thereby reducing the risk of potentially life-threatening complications associated with PE.

In patients who are unable to tolerate anticoagulation therapy due to allergies, bleeding disorders, recent surgery, or other medical conditions that increase the risk of bleeding, or those who have proven recurrent emboli even while on anticoagulants, the IVC filter offers a therapeutic alternative to manage the risk of further PE.

Other options presented, such as minor PE, chronic venous insufficiency, and peripheral artery disease, do not directly relate to the need for IVC filter placement. Minor PE may not necessitate an intervention like an IVC filter, chronic venous insufficiency focuses more on venous return issues rather than embolism prevention, and peripheral artery disease primarily concerns arterial conditions rather than venous thromboembolism. Thus, the focus on recurrent PE or high risk for developing it aptly encapsulates
