| vena-tech ivc filter | <radiology> Introduced as LGM (L.G. Medical, France), 1985; FDA aprroval 1991: Vena-Tech, Evanston, IL, 6-leg conical design with 6 stabilizing side bars, biocompatible metal known as Phynox (cobalt,chromium,iron,nickel,moly) Efficacy, recurrent PE: 2-6%, IVC occlusion: 8-24%, migration: 0-12% Advantages, ease of placement, excellent clot trapping efficiency, low profile, lacks ferromagnetic activity: minimal MRI artifacts Disadvantages, incomplete opening (6-19%): decreases clot-trapping efficiency, increased incidence from IJ approach, decreased with rapid deployment, increased IVC thrombosis rates: 8% initial reports; 22-24% on subsequent reports by ultrasound/MRI: 2-19% clinically symptomatic (12 Dec 1998) |
