The Virtual Intracranial Stenting Challenge 2007 (VISC'07) is becoming a standard test case in computational minimally invasive cerebrovascular intervention. Following views expressed in the literature and consistent with the recommendations of a report, the effects of non-Newtonian viscosity and pulsatile flow are reported. Three models of stented cerebral aneurysms, originating from VISC'07 are meshed and the flow characteristics simulated using commercial computational fluid dynamics (CFD) software. We conclude that non-Newtonian and pulsatile effects are important to include in order to discriminate more effectively between stent designs.
2007 年虚拟颅内血管支架置入挑战赛(VISC'07)正逐渐成为计算性微创脑血管介入治疗的标准测试案例。本研究报告基于文献中的观点,并与一份报告的建议相一致,报告了非牛顿粘度和脉动流的影响。对源自 VISC'07 的三个支架脑动脉瘤模型进行了网格划分,并使用商用计算流体动力学(CFD)软件模拟了血流特性。我们的结论是,为了更有效地区分支架设计,有必要考虑非牛顿和脉动效应。
