Coil stretching is a recognized complication during cerebral aneurysm embolization. 1 , 3 – 5 For over a decade, the microsnare has proven effective in retrieving migrated coils. 1 – 5 Fiorella et al. unveiled the “Monorail Snare Technique” in 2005, offering a specialized approach to stretched coil recovery. 1 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.” 1 , 5 This pivotal adjustment substantially lowers the threat of thromboembolic events. We highlighted essential precautions to ensure the procedure's safety and efficacy. 4 , 5

用于回收拉伸线圈的单轨圈套技术

线圈拉伸是脑动脉瘤栓塞治疗过程中公认的并发症。1 , 3 – 5十多年来，微型圈套器已被证明可以有效地回收迁移的线圈。1 – 5菲奥雷拉等人。 2005 年推出了“单轨圈套技术”，提供了一种拉伸线圈恢复的专门方法。1然而，要完全理解这项技术，仅仅需要文字描述是不够的。彻底、实际的演示是必不可少的。在我们的技术视频（视频 1）中，我们展示了动脉瘤栓塞期间弹簧圈拉伸的一段情节，其中“单轨圈套技术”成功地用于收回拉伸的弹簧圈。我们的视频强调了微圈套器的精心准备和修改，展示了减轻在“单轨圈套器技术”期间专门使用单臂止血阀所引发的潜在血液回流的增强步骤。1 , 5这一关键调整大大降低了血栓栓塞事件的威胁。我们强调了确保手术安全性和有效性的基本预防措施。4 , 5
