摘　　要：目的探讨应用TCD对高血压及脑梗塞患者的脑血管扩张储备功能进行检测的可行性。方法应用TCD对60例高血压、脑梗塞患者和60例正常对照组的脑血管二氧化碳反应性屏气指数进行测定。结果高血压患者脑血管对CO_2的扩张反应低于正常对照组(P<0.01),脑梗塞患者的患侧明显低于健侧(P<0. 05),也低于单纯高血压患者(P<0.05),脑梗塞患者健侧和无脑梗塞的高血压患者间无显著差异(P>0.05)。结论高血压患者的脑血管对CO_2的扩张反应性低于正常对照组,而脑梗塞患者患侧脑血管的反应性降低更为明显,反映了高血压及脑梗塞患者脑血管的扩张储备功能降低,说明TCD是检测高血压及脑梗塞患者脑血管扩张储备功能的可靠、经济、简便易行的有效方法。Objective To probe the possibility for apply TCD to check the potential ability of cerebrovascular dilatation in patients with hypertension as well as cerebral infarction. Methods Sixty cases of hypertension as well as cerebral infarction were mensurated by TCD for their cerebrovascular reactivity to CO2 by hold one＇s breath. Results The cerebrovascular reactivity to CO2 in cases with hypertension were lower than normal control（ P 〈 0.01 ）. In cases with cerebral infarction, the reactivity of sick side was lower than non - sick side{ P 〈 0.05）as well as the hypertension {without cerebral infarction ） group{ P 〈 0.05）. But there was no significant between nonsick side of cerebral infarction group and the hypertension （ without cerebral infarction ） group （ P 〉 0.05 ）. Concision The cerebrovaseular reactivity to CO2 was lower in patients with hypertension especially in sick side of cerebral infarction group . This revealed that the potential ability of cerebrovascular dilatation with hypertension as well as cerebral infarction was impaired and shown that TCD is a reliable, economic and yeasily to be learned method to check the potential ability of cerebrovascular dilatation in patients with hypertension as well as cerebral infarction
