Advancement in the haemodynamic study of intracranial aneurysms by computational fluid dynamics

As a promising risk stratification tool, computational fluid dynamics plays an important role in the evaluation of the growth and rupture of intracranial aneurysms. However, many of the experimental results obtained with this tool are inconsistent with real pathophysiological manifestations, which has confused researchers and clinicians. These contradictory results may be due to the inconsistency of parameter definitions, the small amount of data, and the complexity and heterogeneity of the growth and rupture of intracranial aneurysms. In this paper, by summarizing the research results of computational fluid dynamics in recent years, the author tries to find out the broad causes of the problem of explicit modelling error and propose possible solutions.(c) 2020 International Hemorrhagic Stroke Association.
