This study was performed to assess the effect of aneurysm geometry on parameters that may have an impact on the natural history of intracranial aneurysms, such as intraaneurysmal flow pressure and shear stress. Flow was simulated in 21 randomly selected aneurysms using finite volume modeling. Ten aneurysms were classified as side-wall aneurysms, with either(More)
BACKGROUND AND PURPOSE Cerebral aneurysms are preferentially located at arterial curvatures and bifurcations that are exposed to major hemodynamic forces, increasingly implicated in the life cycle of aneurysms. By observing the natural history of aneurysm formation from its preaneurysm state, we aimed to examine the hemodynamic microenvironment related to(More)
The results of thromboscintigraphy of the carotid artery in comparison to angiography and clinical analysis in patients with cerebral infarcts are reported: A bilateral thrombosis of the carotid artery, occlusion of one carotid artery for more than a year, thrombosis of the carotid artery under treatment with Marcumar and a thromboscintigraphy within a few(More)
