目的综述计算流体动力学（CFD）在评估颅内动脉瘤破裂风险中的临床作用。各种血流动力学参数，如壁面剪切应力（WSS）和振荡剪切指数（OSI）的有用性，以及它们在动脉瘤破裂风险分析中的作用，进行了分析。结果作者确定了共258篇已发表的文章，评价破裂风险，增长，血管内器械评估。在这258篇文章中，确定了113篇与导致破裂风险的CFD和血流动力学参数（如WSS和OSI）匹配的文章。然而，由于缺乏标准化的方法，争议仍然存在于每个参数的role.CONCLUSIONS虽然争议继续存在的风险因素有助于预测动脉瘤破裂，CFD可以提供额外的参数来评估这种破裂的风险。该技术有助于临床决策或血管内方法和器械的有效性评价。
OBJECTIVE The authors reviewed the clinical role of computational fluid dynamics (CFD) in assessing the risk of intracranial aneurysm rupture.METHODS A literature review was performed to identify reports on CFD assessment of aneurysms using PubMed. The usefulness of various hemodynamic parameters, such as wall shear stress (WSS) and the Oscillatory Shear Index (OSI), and their role in aneurysm rupture risk analysis, were analyzed.RESULTS The authors identified a total of 258 published articles evaluating rupture risk, growth, and endovascular device assessment. Of these 258 articles, 113 matching for CFD and hemodynamic parameters that contribute to the risk of rupture (such as WSS and OSI) were identified. However, due to a lack of standardized methodology, controversy remains on each parameter's role.CONCLUSIONS Although controversy continues to exist on which risk factors contribute to predict aneurysm rupture, CFD can provide additional parameters to assess this rupture risk. This technology can contribute to clinical decision-making or evaluation of efficacy for endovascular methods and devices.
