脑血管疾病的血液动力学研究一直是和脑血管疾病的预防和诊断密切相关的,由于脑部血液循环是一个四端输入的网络,其复杂性导致它的血液动力学规律和体循环有着本质的差别,讨论脑循环动力学模型和临床应用有着重要的意义。本文使用集中参数模型来模拟三种常见的脑血管疾病;脑动脉硬化,脑梗塞,锁骨下动脉盗血。考察其对相应脑血管的压力和流量的影响,结果显示脑部血液循环的代偿功能在发病情况下的重要作用,本文通过分析数值模拟结果,对不同疾病的血液动力学特征进行研究,给脑血管疾病的临床诊断提供血液动力学方面的参考。
Hemodynamic studies of cerebrovascular diseases have been closely linked to the prevention and diagnosis of cerebrovascular diseases. Since the blood circulation in the brain is a four-terminal input network, its complexity leads to its own laws of hemodynamics and systemic circulation Differences, discussion of brain circulation dynamics model and clinical application of great significance. This article uses a centralized parameter model to simulate three common cerebrovascular diseases; cerebral arteriosclerosis, cerebral infarction, subclavian artery steal. Investigate its impact on the corresponding cerebrovascular pressure and flow, the results show that the compensatory function of blood circulation in the brain plays an important role in the pathogenesis of this article by analyzing the numerical simulation results, the study of different diseases, hemodynamic characteristics, to The clinical diagnosis of cerebrovascular disease provides a reference to hemodynamics.
