【摘要】 目的探讨超声多普勒对缺血性脑血管病进展的预测价值。方法对经脑CT证实的缺血性脑血管病神经症状体征稳定组37例、不稳定组36例分别行超声多普勒检查颈动脉,观察颈动脉有无硬化斑块、斑块的性质及颈动脉狭窄程度。结果不稳定组36例有18例颈动脉有斑块,其中低回声9例,等回声6例,高回声3例。颈动脉狭窄<50%1例,51%～70%13例,71%～90%4例。稳定组37例有斑块6例,均为高回声,其中颈动脉狭窄>50%1例,<50%5例。两组斑块发生率及颈动脉狭窄程度有明显差异(P<0.01)。结论超声多普勒对缺血性脑血管病神经症状体征有一定预测性,斑块回声低,狭窄程度>50%神经症状体征不稳定,斑块回声高,狭窄<50%神经症状相对稳定。更多还原

【Abstract】 Objective to explore the predictive value of the advance of Ischemia Vascular accident by three-function Ultrasound.Methods Among the cases with Ischemia Cerebral Vascular accident 37 cases with steady symptom and with unsteady symptom were examined respectively.Observing the existence and carotid artery stenosis severity of the hard plaques..Results 18 of 36 cases with unsteady symptom have hard plaques.9cases with hypoecho,6 cases with medium,3 cases with hyperecho.1 cases with carotid artery stenosis(<50%).13 cases(51%-70%),4 cases(71%-90%),6 of 37 cases with steady symptom having hard plaques are hypercho,1 case(>50%),5 cases(<50%).The difference of the existence rate of hard plaque and carotid artery stenois severity between them are very great(P<0.01).Conclusions Three-function utrasound can predict the Ischemia Cerebral Vascular accident to some degree.If the echo is low and carotid artery stenosis severity is more than 5%,the neural symptom is steady and vice versa.更多还原
