Abstract
Thrombogenesis is said to play an important role in the rupture of cerebral artery
aneurysms and it was reported that the degree of platelet aggregation in an
aneurysm had a significant correlation with the flow pattern in the aneurysmal
dome. In this study, flows in three different models of cerebral saccular
aneurysms at artery bifurcations were numerically investigated to compare flow
patterns from a viewpoint of likelihood of platelet aggregation. It was shown that
the relative size of the aneurysmal dome had a greater influence on the formation
of a low-speed region responsible for active platelet aggregation than geometric
features such as the aspect ratio of the aneurysm and the angle of the bifurcation.
Keywords: cerebral saccular aneurysm, computational fluid dynamics, platelet
aggregation, anterior communicating artery, artery bifurcation.
