摘要：

Hemodynamics　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.
