The initiation and progression of cerebral aneurysms are degenerative processes of the arterial
wall driven by a complex interaction of biological and hemodynamic factors. Endothelial …

INTRODUCTION: Intracranial pial single-channel arteriovenous (AV) fistulae are rare vascular
lesions of the brain. They differ from AV malformations in that they lack a true “nidus” and …

BACKGROUND AND PURPOSE: Hemodynamic factors are thought to play an important
role in the initiation, growth, and rupture of cerebral aneurysms. This report describes a pilot …

Because of its ability to deal with any geometry, image‐based computational fluid dynamics
(CFD) has been progressively used to investigate the role of hemodynamics in the …

… 0.02 cm and 0.01 cm. The resulting grids contained between 1 and 5 million elements. …
inlet boundaries to achieve a mean WSS of 15 dyne/cm 2 at the inlets, which were located in the …

BACKGROUND AND PURPOSE: Flow-diverting approaches to intracranial aneurysm
treatment had many promising early results, but recent apparently successful treatments have …

… ranged from 10 to 230 dyne/cm 2 (mean, 114 dyne/cm 2 ) compared with ruptured
aneurysms, which ranged from 35 to 1500 dyne/cm 2 (mean, 271 dyne/cm 2 ). This difference in …

Purpose The purpose of this work was to evaluate the accuracy of CT angiography (CTA) for
the detection of large vessel intracranial thrombus in clinically suspected hyperacute (< 6 h) …

… cm and a peak velocity of 100 cm/s, we have a Reynolds number of 1250. The distances
required to reach a fully developed flow in laminar and turbulent systems would be 37 and 7 cm…
