Figure 1: A computational fluid dynamic. (a) Moderate wall pressure within the sac of the basilar artery tip aneurysm; (b) wall shear stress vectors showing change in the direction of angle of the vectors at the neck and sac of the aneurysm in comparison with the vectors in the bifurcation; (c) wall shear stress pressure showing a low wall shear stress pressure within the aneurysmal sac, suggestive of low flow within the aneurysmal sac with high risk of rupture in a narrow neck and small saccular aneurysm; (d) streamline showing disturbed laminar flow within the sac of the aneurysm
