Dislocation of inferior vena cava filter (IVCF) is a rare complication with potential IVC perforation and other life-threatening risks requiring early diagnosis and in-time retrieval. Most of dislocation IVCF in the past have been shelved or removed by open surgery. It is very difficult to retrieve the filters by interventional technology.
Here we report a 49-year-old man suffering from dislocation of IVCF implanted due to deep vein thrombosis (DVT) in the right femoral vein. Successful retrieval of the IVCF using double sheaths docking technique was done soon after confirmation of the dislocation. Importance of monitoring and early detection of dislocation of IVCF should be emphasized to avoid further complications.
The double vascular sheaths docking technique can be considered as a preferential option in difficult operative situation.
下腔静脉滤器（IVCF）移位是一种罕见的并发症，存在下腔静脉穿孔及其他危及生命的风险，需要早期诊断并及时取出。过去大多数移位的IVCF被搁置或通过开放手术取出。通过介入技术取出滤器非常困难。
在此，我们报告一名49岁男性，因右股静脉深静脉血栓形成（DVT）植入的IVCF发生移位。在确认移位后不久，采用双鞘对接技术成功取出了IVCF。应强调监测和早期发现IVCF移位的重要性，以避免进一步的并发症。
在困难的手术情况下，双血管鞘对接技术可被视为一种优先选择。
