METHODS: The 3D multifusion image enabled visualization of the orientation and shape of the clip within the clipped neck complex, alongside the morphology of the parent vessel. In the hemodynamic analysis of the parent vessel at the clipped neck, areas of high-intensity magnitude of wall shear stress (WSSm) variation corresponding to the clip\'s contour, along with significant vector of wall shear stress (WSSv) variation related to vector directionality, were visualized in 3D. The intentional residual neck, coated with muscle grafts, was depicted as an area with low WSSm variation values and high WSSv variation values.
CONCLUSIONS: Three-dimensional multifusion imaging, along with computational fluid dynamics analysis of the parent vessels, facilitated both the morphological and hemodynamic visualization and assessment of the clipped neck complex following neck clipping surgery for cerebral aneurysms. https://thejns.org/doi/10.3171/CASE24194.
方法:3D多融合图像使夹颈部复合体内夹子的方向和形状可视化,沿着父血管的形态。在夹住颈部的母体血管的血液动力学分析中,对应于夹子轮廓的高强度墙剪应力(WSSm)变化的区域,连同与矢量方向性相关的壁剪应力(WSSv)变化的显著矢量,在3D中可视化。故意残留的脖子,涂有肌肉移植物,被描绘为具有低WSSm变化值和高WSSv变化值的区域。
结论:三维多融合成像,以及母血管的计算流体动力学分析,促进了脑动脉瘤颈部夹闭手术后颈部夹闭复合体的形态学和血流动力学可视化以及评估。https://thejns.org/doi/10.3171/CASE24194.
