Abstract: The importance of the blood flow feature on the hemorrhage of the cerebral aneurysm is confirmed by surgeons and scientists. In this paper, the effects of blood hemodynamics on the growth and rupture of the Internal Carotid Intracranial (ICA) are fully investigated. This study tries to demonstrate the blood feature inside the ICA at different time stages. Besides, the effect of coiling on blood characteristics is extensively studied in this research. Computational Fluid dynamic (CFD) is used for the analysis of the blood hemodynamics on the wall shear stress and pressure distribution within the aneurysm. Obtained results indicate that reducing the coiling porosity from 0.89 to 0.79 declines maximum WSS by about 26% and 61% for HCT = 0.35 and 0.45, respectively, at the peak systolic stage. Our findings show that decreasing the porosity (or increasing coiling fraction) would decrease the maximum OSI by more than 55% in high blood viscosity of HCT = 0.45.
