Outline of Final Research Achievements

We analysed relationship between cerebral aneurysm enlargement and hemodynamic stress with computational fluid dynamics. Enlarged aneurysms had broader area with gap between wall shear stress and oscillatory shear index. The results may contribute to prediction of high risk cerebral aneurysms in advance of radical treatment.
