Abstract: The impact of flow-diverters used in the treatment of cerebral aneurysm on human brain hemodynamics was evaluated qualitatively and quantitatively. Numerical simulation of flow-diverter placement in cerebral vessels with aneurysms for the case history of a real patient was carried out with the commercial ANSYS 17.2 package, using different (Newtonian and non-Newtonian) hydrodynamic models of blood rheology in different parts of the vessel and aneurysm, according to experimental data. It is shown that after flow-diverter placement, the blood flow through the artery segment containing the aneurysm neck decreases, resulting in a redistribution of the cerebral blood flow, which becomes close to a healthy bloodstream. Changes in wall tangential stresses in the flow-diverter region are indicative of possible aneurysm recanalization.
Keywords: cerebral aneurysm, flow-diverter, brain hemodynamics, reconstruction of DICOM images, non-Newtonian blood rheology.
