Risk stratification of cerebrovascular aneurysms using CFD - a review

Management of cerebral aneurysms is currently done solely based on clinicians’ experience and knowledge. Computational fluid dynamics (CFD), a numerical method aims to provide data that will help in clinical decision making and in the treatment of cerebral aneurysms. A review of relevant research conducted to date was incorporated in this paper to delineate the current standing in our grasp of the various hemodynamic and morphologic parameters that might play a crucial role in the initiation, growth and rupture of cerebral aneurysms. The limitations of CFD from a hemodynamic point of view are discussed in detail. This helps us to identify the areas of future research that is essential to improve the accuracy of its clinical application.
