In Reply We are grateful that our Viewpoint has generated considerable interest, igniting debate regarding the inferior vena cava filter (IVC) filter. In our original article,1 we argue that the IVC filter has no evidence supporting its use. Randomized trials have failed to show improvements in mortality. Instead, IVC filters carry real harms, especially increases in subsequent deep vein thromboses (DVTs), and dubious benefits, reducing instances of pulmonary embolism diagnosed using telephone screening.
