Flow dynamics in intracranial aneurysms and their adjacent parent vessels play important roles in the development and rupture of intracranial aneurysms. Especially, we assume that wall shear stress is concerned with rupture of intracranial aneurysms. In this study, we measure the unsteady flow made by sin wave generater in the realistic cerebral resin model by using LDV. The Reynolds number was adjusted to the blood flow in the actual internal carotid artery. The flow in intracranial aneurysm form anticlockwise rotational flow. And the center of rotational flow is stationary in each phases. In neighborhood of bleb, flow is going highly-complex. It seems that this highly-complex flow in bleb will trigger the rupture of aneurysm.
