Coil stretching is a recognized complication during cerebral aneurysm embolization. For over a decade, the microsnare has proven effective in retrieving migrated coils. Fiorella et al. unveiled the "Monorail Snare Technique" in 2005, offering a specialized approach to stretched coil recovery. However, to gain a complete understanding of this technique, more than just textual descriptions are necessary; a thorough, practical demonstration is essential. In our technical video (video 1), we illustrated an episode of coil stretching during aneurysm embolization, where the "Monorail Snare Technique" was successfully employed to retrieve a stretched coil. Our video emphasizes the meticulous preparation and modification of the microsnare, showcasing enhanced steps to mitigate the potential blood backflow triggered by the exclusive use of one-arm hemostasis valve during the "Monorail Snare Technique." This pivotal adjustment substantially lowers the threat of thromboembolic events. We highlighted essential precautions to ensure the procedure's safety and efficacy..
弹簧圈拉伸是脑动脉瘤栓塞过程中一种公认的并发症。十多年来，微型圈套器已被证明在取出移位的弹簧圈方面有效。菲奥雷拉等人在2005年公布了“单轨圈套技术”，为拉伸弹簧圈的回收提供了一种专门方法。然而，要全面理解这项技术，仅靠文字描述是不够的；进行全面、实际的演示至关重要。在我们的技术视频（视频1）中，我们展示了动脉瘤栓塞过程中弹簧圈拉伸的一个实例，其中成功应用“单轨圈套技术”取出了一个拉伸的弹簧圈。我们的视频强调了微型圈套器的精心准备和改进，展示了在“单轨圈套技术”中为减轻仅使用单臂止血阀引发的潜在血液逆流而采取的强化步骤。这一关键调整大大降低了血栓栓塞事件的风险。我们强调了确保该操作安全和有效的基本预防措施。
