Author information

University of Medicine and Dentistry of New Jersey-New Jersey Medical School, Newark, NJ, USA.


The Vena Tech LP vena cava filter (B Braun, Evanston, Illinois) has been FDA approved since 2001 and is a permanent vena cava filtration device. It replaced the previous Vena tech LGM filter also manufactured by B Braun. The LGM filter had 2 case series reporting a high incidence of incomplete deployment of the filter, especially when placed from a jugular approach. Design changes were made to this device and the LP filter introduced. The LP filter has also been reported to have incompletely deployed both in peer reviewed literature as well as the FDA MAUDE website. We present here 3 cases of incomplete deployment of the Vena Tech LP filter and review the cases previously described as well as attempt to present possible etiologies for incomplete deployment.
