Abstract: In this research, a computational approach is applied to model the blood flow inside the MCA aneurysm when the coiling technique is used for the treatment of the patients. To this end, porous condition with different permeability factors is applied and their impacts on the hemodynamic factors of wall shear stress, pressure and oscillatory shear index. The main attention is to find how endovascular technique could efficiently decrease the risk of bleeding in MCA aneurysms. Blood hemodynamic is simulated via solving transient Navier–Stokes equations with Casson model for the non-Newtonian condition for the blood stream. Besides, the impacts of the blood hematocrit are also examined on the hemodynamic characteristics. Attained results show that the effects of coiling permeability are significant on the reduction of the blood stress on the aneurysm.
