Inferior Vena Cava Filter

The main vein for transferring blood from the lower part of the body to the heart is the inferior venacava. The doctor can place a filter into your inferior venacava to prevent the clots from reaching your lungs. The procedure does not prevent the formation of new blood clots, but it keeps them from reaching the lungs to cause severe symptoms. Doctors usually prefer inferior venacava filters when blood thinners cannot be used because of recent strokes or surgery that caused bleeding in other parts of the body.
