Abstract
We applied computational fluid dynamic (CFD) analysis on the numerical grid of a 3D rotational digital subtraction angiogram obtained in a 22-year-old male patient, with an accidentally discovered vein of Galen malformation associated with single feeder aneurysm, to understand the flow pattern through the two aneurysms and improve our general understanding of hemodynamic characteristics of this variety of fusiform aneurysm. This technical note provides a good example of the application of CFD to 3D digital subtraction angiography for studying the flow pattern in patients with cerebrovascular disease.
摘要
我们对一名22岁男性患者的三维旋转数字减影血管造影数值网格进行了计算流体动力学（CFD）分析，该患者意外发现了与单一供血动脉瘤相关的大脑大静脉畸形，以了解通过两个动脉瘤的血流模式，并增进我们对这种梭形动脉瘤血流动力学特征的总体认识。本技术说明提供了一个将CFD应用于三维数字减影血管造影以研究脑血管疾病患者血流模式的良好示例。
