Abstract
AbstractHemodynamics are thought to play an important role in the creation, thrombosis, recanalization, regrowth and rebleeding of cerebral aneurysms treated by endovascular means. And the lattice Boltzmann method has received considerable interest as an efficient method of computing a variety of fluid flows, especially with complex geometrical configurations. Therefore, 3-dimensional mathematical model of different cerebral vessels with aneurysm were created. Furthermore, CFD calculations were performed by using lattice BGK model with the assumption of Newtonian fluid property for blood and the rigid wall property for the vessel and the aneurysm. The results suggest that the lattice BGK model has the potential to be a useful clinical tool for the prediction of the hemodynamics in cerebral aneurysm. And the geometric configuration of aneurysm is essential to the hemodynamics in aneurysm.
