Toward Computer Modelling of Blood Flow in an Anatomically Accurate Arterial Tree in Endovascular Interventions

In this chapter, we present a numerical approach to simulate transient blood flow in an anatomically accurate arterial tree that spans the whole range of arteries involved in typical endovascular neuro-interventions. To serve this purpose, a cerebral arterial tree is coupled with an arterial tree based on the Visual Human Project (VHP). Blood flow in the arterial tree is solved by using a one-dimensional (1D) formulation of the governing viscous flow equations. We propose a strategy for modelling endo-devices in the vascular network. We show some preliminary results, including the transient flow in the arterial tree and the simulation of a balloon–occlusion procedure in vertebral arteries.
