To the Editor We read with great interest the Original Investigation by Sarosiek et al1 and the accompanying Viewpoint by Prasad et al2 regarding the efficacy and safety of inferior vena cava filters. Sarosiek et al1 reported suboptimal outcomes of metallic retrievable stents with an extremely low retrieval rate. In Japan, temporary inferior vena cava filter system, which is made of fluorinated ethylene propylene polymer, is widely available to circumvent the difficulty in retrieval. The filter is a catheter-like device, inserted and placed through jugular vein for only a limited period. We have, however, recently reported that this polymer filter system is also associated with a high rate of complications including filter thrombosis, filter dislocation, and catheter-related infection.3 The benefit of medical technology should be carefully weighed against its safety. We fully agree that we need randomized clinical trials to elucidate the clinical necessity of inferior vena cava filtering.
