An IVC filter is a small metal device implanted in the inferior vena cava, the large vein that returns blood back to the heart from the lower body. It is placed in the vein to prevent dangerous blood clots from traveling to the lungs.
Why should a filter be removed?
IVC filters may need to be removed because they can increase risks of new blood clot formations in the legs and abdomen. Certain filter types have been found to fracture and/or cause symptoms from the filter legs penetrating the wall of the inferior vena cava. Removal is also recommended when the filter is no longer needed, according to the United States Food and Drug Administration.
