在颅内动脉瘤的弹簧圈栓塞中，适当选择最适合应对各种不可预见情况的弹簧圈非常重要。此外，由于动脉瘤囊的密集弹簧圈填塞是避免复发的最重要因素，因此正确选择弹簧圈至关重要。在这篇文章中，作者测量的线圈插入压力的各种类型的线圈与一个新开发的传感器系统，和线圈特性进行了investigated.MethodsThe传感器由一个止血阀连接到近端的微导管。传感器原理基于光学系统。使用该装置，以恒定速度自动进行实验性硅胶动脉瘤栓塞。分析不同类型弹簧圈的插入压力和最大插入压力（MIP）模式。该传感器连续监测的机械力在inserts.ResultsThe传感器充分记录在每个线圈栓塞过程中的线圈插入压力。MIP通常按弹簧圈类型排序。与标准/螺旋和3D型相比，软型弹簧圈需要相对较小的插入压力。至于弹簧圈插入压力的模式，每个弹簧圈呈现锯齿状压力模式，尽管我们观察到一些轻微差异。3D型弹簧圈在“涂漆”时刻显示峰值压力。弹簧圈环直径几乎不影响MIP。然而，对于压力的模式，较大尺寸的线圈更经常出现peak.ConclusionsCoil特性得到很好的评价。本研究的结果反映了一些实际的临床经验。此外，必须收集体内研究，这可能提供临床有用的数据。
IntroductionIn coil embolization for an intracranial aneurysm, it is important to appropriately choose the coil most suitable for coping with various unforeseen situations. Additionally, because dense coil packing of the aneurysm sac is the most important factor to avoid a recurrence, properly selecting the coil is essential. In this article, the authors measured the coil insertion pressure of various types of coils with a newly developed sensor system, and coil characteristics were investigated.MethodsThe sensor consists of a hemostatic valve connected to the proximal end of a microcatheter. The sensor principle is based on an optical system. Using this, an experimental silicone aneurysm embolization was performed automatically at constant speed. The pattern of the insertion pressure and the maximum insertion pressure (MIP) were analyzed for the various types of coils. The sensor continuously monitored the mechanical force during the insertions.ResultsThe sensor adequately recorded the coil insertion pressure during embolization in each coil. MIP was generally ranked in order of the coil type. The soft type coils required relatively less insertion pressure than standard/helical and 3D type. As for the patterns of coil insertion pressure, each coil presented a saw-like pressure pattern, though we observed some slight differences. 3D type coils showed peak pressure at the moment of “painting”. Coil loop diameters barely affected MIP. However, as to the patterns of pressure, larger size coils more often presented the peak.ConclusionsCoil characteristics were well evaluated. The results obtained here reflected some actual clinical experience. Furthermore, collecting the in vivo study is mandatory, which may provide clinically useful data.
