Retrieval of a permanent VenaTech LGM filter 18 years after implantation using a novel removal method.

The VenaTech LGM (B. Braun, Melsungen, Germany) inferior vena cava (IVC) filter was designed as a permanent IVC filter to prevent clot migration and pulmonary embolism. This filter has been discontinued, but thousands remain implanted within patients who incur the added long-term risks of an indwelling IVC filter. We present a case of successful removal of a permanent VenaTech LGM IVC filter using a novel technique in a patient in whom filter placement was no longer indicated. The conical portion of the filter was removed intact, and the vertical struts were intentionally left embedded extravascularly within the caval wall.
