The IVC is the largest vein in your body. It carries blood from your lower body to your heart and lungs.
Blood clots are treated with anticoagulants, but some people may not be able to receive this treatment. In those cases, an IVC filter may be placed, usually temporarily until the individual can use blood thinners
An IVC filter is a small device that is placed in your inferior vena cava to prevent blood clots from moving through your blood into your lungs. An IVC filter is typically placed by an interventional radiologist (a doctor who specializes in image-guided procedures).
