 The abstract summarizes the research conducted by the authors. The main focus was on the effect of stents on the internal carotid artery aneurysms. The authors used computational fluid dynamics to simulate the non-Newtonian bloodstream with one-way FSI approach. They then simulated four aneurysms with varying ostium size and neck vessel angle. The results showed that the deformation of the aneurysm limited blood entrance into the sac region which decreased the blood velocity and consequently the oscillatory shear index, OSI. Additionally, it was found that the stent-induced deformation was more effective on those cases with higher OSI values on the aneurysm wall.
