目的神经血管分流器是治疗颅内动脉瘤的一种有弹性的、纵横交错的网状支架。本研究采用动态推-拉技术调节动脉瘤瘤口分流器的网格密度,以便最大化其导流作用。通过自主研发的高保真虚拟支架计算机模型技术联合计算机流体动力学,探讨动态推-拉技术对特定动脉瘤病人血流动力学的影响。方法采用动态推-拉技术和不同长度的传送导线,将两个Pipeline分流器放置到两个相同侧壁的大脑前动脉动脉瘤模型中。然后数字模拟操作过程,并验证模拟的网格几何结构。通过调节放置在侧壁动脉瘤和基底动脉主干 Objective The neurovascular shunt is a flexible, criss-crossed mesh stent for the treatment of intracranial aneurysms. In this study, the dynamic push-pull technique was used to adjust the mesh density of the aneurysm neoplasm splitter in order to maximize its guiding effect. Through self-developed high-fidelity virtual scaffold computer model technology combined with computer fluid dynamics, to explore the dynamic push-pull technology for patients with aneurysm hemodynamics. Methods Two Push-Pull diverters were placed into two models of anterior cerebral artery aneurysms with the same lateral wall using dynamic push-pull technique and different lengths of delivery wire. Then the numbers simulate the process and verify the simulated grid geometry. By adjusting the placement of the aneurysm in the sidewall and the basilar artery
