title: Wall shear stress variations in basilar tip aneurysms investigated with computational fluid dynamics.
abstract: Hemodynamics are thought to play an important role in the creation, thrombosis, recanalization, regrowth and re-bleeding of cerebral aneurysms treated by endovascular means. However, their exact role and interaction is unclear and warrants further study. Towards a systematic classification of the hemodynamics in intracranial aneurysms, we investigated the dependence of the values of the magnitude of the wall shear stresses in the vicinity of the aneurysm on varying inflow conditions in three basilar tip aneurysms.
