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.
德国贝朗梅尔松根公司的 VenaTech LGM 下腔静脉（IVC）滤器最初设计为永久性 IVC 滤器，以防止血栓迁移和肺栓塞。该滤器已停产，但仍有数以千计的患者体内植入了该滤器，这些患者面临着长期留置 IVC 滤器的额外风险。我们介绍了一种使用新技术成功取出永久性 VenaTech LGM IVC 滤器的病例，该患者已不再需要植入滤器。滤器的锥形部分被完整取出，而垂直支柱则故意留在腔静脉壁的血管外。
