Abstract (EN): The present study quantifies the effect of stenting on the hemodynamics of a carotid stenosis under realistic conditions. The geometry and flow conditions are based on specific data to simulate the hemodynamics and to enhance the potential application of computational fluid dynamics prediction to clinical surgical planning. 3D models of stenotic artery were created before and after stent implantation, and realistic boundary conditions were imposed at the inlet and outlet of the computational vessels. The geometric configuration of vascular segments greatly affects the resulting flow patterns. ANSYS/Fluent software was used to perform the tetrahedral mesh generation and the blood flow simulation. The results show that stenting increased the blood flow rate compared to that for the stenosis artery model and that the hemodynamic values returned to near normal levels in the carotid artery fitted with a stent.
