Background. Coil and stent migration is a potentially catastrophic complication in endovascular neurosurgery, which may lead to cerebral thromboembolism. Techniques for removing migrated coil and stent are not well established. Methods and Results. We present three cases in which coil or stent migration occurred during endovascular embolization of a cerebral aneurysm. The Merci Retrievers were used successfully in all cases to remove the displaced foreign bodies. Technical details are described. Conclusion. The Merci Retriever device can be utilized successfully for removal of migrated coils and stents in endovascular neurosurgery.
背景。弹簧圈和支架移位是血管内神经外科手术中一种潜在的灾难性并发症，可能导致脑血栓栓塞。取出移位的弹簧圈和支架的技术尚未完全确立。方法与结果。我们报告3例在脑动脉瘤血管内栓塞过程中发生弹簧圈或支架移位的病例。所有病例均成功使用Merci取栓器取出移位的异物。文中描述了技术细节。结论。在血管内神经外科手术中，Merci取栓器可成功用于取出移位的弹簧圈和支架。
