The magnetic navigation system consists of an externally generated magnetic field that is used to control and steer a magnetically tipped microguidewire. The goal of this study was to demonstrate that the use of the magnetic navigation system and its magnetic microguidewire is feasible and safe in all types of neuroendovascular procedures.
A magnetic navigation system is an interventional workstation that combines a biplanar fluoroscopy system with a computer-controlled magnetic field generator to provide both visualization and control of a magnetically activated endovascular microguidewire. Ten consecutive patients underwent a variety of neuroendovascular procedures using the magnetic guidance system and magnetic microguidewire. All patients presented with a neurovascular disease that was suitable for endovascular treatment. Multiple different devices and embolic agents were used.
Of the ten patients, three were male and seven female. Their mean age was 53.9 years. The predominant neurovascular condition was the presence of intracranial aneurysm (nine patients). One patient had a left mandibular arteriovenous malformation. All treatments were successfully performed on the magnetic navigation system suite. The magnetic navigation system and the magnetic microguidewire allowed safe and accurate endovascular navigation allowing placement of the microcatheters in the desired location. There were no neurological complications or death in our series.
The use of the magnetic navigation system and the magnetic microguidewire in the endovascular treatment of patients with neurovascular diseases is feasible and safe.
磁导航系统由一个外部产生的磁场组成，该磁场用于控制和引导带有磁性尖端的微导丝。本研究的目的是证明在所有类型的神经血管介入手术中使用磁导航系统及其磁性微导丝是可行且安全的。
磁导航系统是一种介入工作站，它将双平面荧光透视系统与计算机控制的磁场发生器相结合，以实现对磁性激活的血管内微导丝的可视化和控制。连续10例患者使用磁导航系统和磁性微导丝进行了各种神经血管介入手术。所有患者均患有适合血管内治疗的神经血管疾病。使用了多种不同的器械和栓塞剂。
10例患者中，男性3例，女性7例。他们的平均年龄为53.9岁。主要的神经血管疾病是颅内动脉瘤（9例）。1例患者患有左下颌动静脉畸形。所有治疗均在磁导航系统套件上成功完成。磁导航系统和磁性微导丝实现了安全、准确的血管内导航，使微导管能够放置在理想位置。我们的系列研究中没有出现神经并发症或死亡。
在神经血管疾病患者的血管内治疗中使用磁导航系统和磁性微导丝是可行且安全的。
