The implantation of an Inferior Vena Cava (IVC) filter is an alternate or adjunctive treatment option for preventing pulmonary embolism in patients who are unable to receive anticoagulation therapy or who have a pulmonary embolism recurrence despite anticoagulation therapy. Typically, patients need the filter for only a short duration, after which it can be removed. However, the longer the filter is in place, the more difficult the retrieval can be. Removing the IVC filter is essential for avoiding complications. To increase the success rate of removing filters that have become embedded at the tip, innovative approaches have been developed. The snare technique is a frequently employed technique. We present a case study that demonstrates the single access 2-snare strategy, a revolutionary approach of removing a sophisticated Günther Tulip IVC filter. This technique involves inserting 2 snares into the jugular vein, grasping the filter on both sides, and exerting sufficient force to detach and straighten it from the caval wall. After unsuccessful attempts to advance the filter into the sheath, it was removed immediately from the jugular vein. Hemostasis was attained after a successful withdrawal. The single access 2-snare technique described here provides a novel solution for the difficult retrieval of IVC filters.
植入下腔静脉(IVC)滤器是一种替代或辅助治疗选择,用于预防无法接受抗凝治疗或尽管接受抗凝治疗仍发生肺栓塞复发的患者发生肺栓塞。通常,患者仅在短时间内需要滤器,之后即可取出。然而,滤器放置的时间越长,取出就越困难。取出IVC滤器对于避免并发症至关重要。为了提高取出已嵌入尖端的滤器的成功率,已经开发了创新方法。圈套技术是一种常用技术。我们展示了一个病例研究,该研究展示了单通道双圈套策略,这是一种取出复杂的Günther Tulip IVC滤器的革命性方法。该技术包括将两个圈套器插入颈静脉,从两侧抓住滤器,并施加足够的力将其从腔静脉壁上分离并拉直。在尝试将滤器推进鞘管失败后,立即从颈静脉将其取出。成功取出后实现了止血。这里描述的单通道双圈套技术为难取出的IVC滤器提供了一种新的解决方案。
