Extract

To the Editor The recent Viewpoint by Prasad and colleagues1 highlights the PREPIC (Prevention du Risque d’Embolie Pulmonaire par Interruption Cave)2 study finding of an increased filter-related deep vein thrombosis (DVT) rate to condemn filter placement, yet the authors discount the filter-related 9% absolute risk reduction in pulmonary embolism (PE), even though the methodology used was the same for both measures. We find the inference that filters cause more harm than good in patients with venous thromboembolism (VTE) to be contrary to the available evidence.
