Abstract

Longitudinal hemodynamic assessment of intracranial aneurysms (IAs) with endovascular treatment is essential for clinical decision making. We proposed a hemodynamic simulation method to explore the hemodynamic characteristics of a certain growth process of IA with virtual Silk stent implantation. Eight growth point models of IA were created by applying a bidirectional linear growing algorithm on patient 3D rotational angiography images. Simulated experiments showed that the WSS and velocity were significantly decreased with virtual Silk stent implantation at all growth points considered. The simulations revealed the flow pattern and WSS characteristics of IA growth.
