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.

Virtual Work
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...
