Vena Caval Filters for the Prevention of Pulmonary Embolism

Abstract
In their report of the efficacy and safety of vena caval filters in patients with proximal deep-vein thrombosis, Decousus et al. (Feb. 12 issue)1 conclude that the initial benefit of vena caval filters for the prevention of pulmonary embolism was counterbalanced by an excess of recurrent deep-vein thrombosis, without any difference in mortality.
