Abstract

Hemodynamically induced wall shear stress plays an important role in the progression and rupture of cerebral aneurysms. The current work describes Computational Fluid Dynamics (CFD) simulations in anatomically realistic models of cerebral aneurysms. Twenty two lateral and ten terminal aneurysms models were investigated; the effects of simple stent models as endovascular treatment in one lateral aneurysm model were also reported. The models were obtained from threedimensional rotational angiographic imaging data and CFD were studied under the same physiologically representative waveform of inflow. The flow was assumed to be laminar, non-Newtonian and incompressible. The CFD models were solved with the finite elements package ADINA. © 2011 Pushpa Publishing House.
