彩色经颅多普勒相关血流动力学参数与脑梗死的关系

脑梗死发生与血流动力学改变密切相关,运用彩色经颅多普勒(TCD)可以精确地测量平均血流速度、搏动指数、脑血管储备能力等血流动力学参数。平均血流速度的变化、搏动指数的改变、脑血管储备能力的高低,与脑梗死的发生、发展、诊断、治疗和预后密切相关。近年来国内外学者通过运用TCD对脑梗死患者的血流动力学改变做了大量的研究,现将这些研究成果予以综述。

Relationship between Hemodynamic Parameters of Transcranial Doppler and Cerebral Infarction

Cerebral infarction is closely related to hemodynamics.Some hemodynamic parameters,such as mean flow velocity,pulsatility index,and cerebrovascular reserve capacity,can be accurately measured by using transcranial Doppler.In recent years,scholars worldwide have done a lot of researches through TCD.In order to guide the early diagnosis and treatment of cerebral infarction,recent studies by TCD on hemodynamic changes of cerebral infarction are reviewed in this article.
