The retrieval of inferior vena cava (IVC) filter is essential for preventing complications associated with the device. Advanced techniques have been developed to improve the success rate of retrieving tip-embedded filters. The forceps technique is frequently used to address this issue. We present a case study of two patients who underwent a successful tip-embedded IVC filter retrieval using a modified forceps technique, which has not been previously reported. This technique involves using a wire loop under the filter tip and a forceps to grasp the filter shoulder. By pulling the wire loop and pushing the forceps in counterforce, the filter tip is straightened and aligned with the vascular sheath. The vascular sheath can then dissect the filter tip out from the caval wall and get inside the sheath to complete the retrieval. The modified forceps technique we present here offers a new solution for the complex retrieval of IVC filters.

使用改进的镊子技术成功取出尖端嵌入的下腔静脉过滤器：病例报告

取出下腔静脉 (IVC) 过滤器对于预防与该装置相关的并发症至关重要。先进的技术已经被开发出来，以提高回收尖端嵌入式过滤器的成功率。镊子技术经常用于解决这个问题。我们提出了一个案例研究，两名患者使用改良的镊子技术成功地进行了尖端嵌入的下腔静脉过滤器检索，这在以前没有报道过。该技术涉及使用过滤器尖端下方的线环和镊子来抓住过滤器肩部。通过拉动线环并以反作用力推动镊子，过滤器尖端被拉直并与血管鞘对齐。然后，血管鞘可以将过滤器尖端从腔壁切开并进入鞘内部以完成回收。我们在此介绍的改良镊子技术为 IVC 过滤器的复杂检索提供了一种新的解决方案。
