Intracranial aneurysms are lesions of the arterial wall characterized by weakening and dilation of an arterial segment. These lesions are a major threat to the patient’s life because of the risk of rupture, thrombo-emboli, or compression of adjacent tissue. The rupture of an intracranial aneurysm causes subarachnoid hemorrhage associated with high mortality and morbidity rates. In order to understand the intracranial aneurysm hemodynamics, it has been developed computational studies, which simulate the boundary conditions and properties of these lesions in virtual models (models similar to reality), most of them are made in a computational fluid dynamic model (CFD). This study reviews the state of arts of the CFD technique applied to the aneurysm flow hemodynamics that claims to collect the most important progress of the method that will be useful in the tool’s developments that will become a rely on a diagnosis and treatment tool.

Keywords : Intracranial aneurysm; Computational fluid dynamic model; Pulsatile flow; Wall shear stress.
