| dc.description.abstract | The Willis polygon is an arterial structure of great importance for the cerebral circulation, because in addition to distributing the cerebral blood flow, it provides collateral blood passages in cases of stenosis and occlusion of the arteries downstream. This study aims to simulate the hemodynamics of the Willis polygon and to compare it with the literature data. For this, 3D models were created in SOLIDWORKS 2017 and simulated in ANSYS FLUENT 15.0. The data from the output sections were extracted and specific sections were analyzed. Comparing the models it was noted that, in steady state, 75% stenosis does not have much impact on cerebral bloodflow. In addition the shear rate was lower than that which would cause stenosis in a Willis polygon in both models. | |
