目的应用彩色经颅多普勒超声(transcranial doppler,TCD)对健康人群中可能存在颅内血管狭窄者进行筛查,以便及早干预、降低脑血管病的发生率。方法应用德力凯EMS-9PB型彩色经颅多普勒超声仪进行检测。结果在36~55岁之间,伴高血压、糖尿病、高脂血症体检者中,TCD提示颅内血管狭窄更为常见。各年龄组前循环血管狭窄比较,X2=4.584,P=0.469;各年龄组MCA和/或TICA狭窄比较,X2=3.320,P=0.651;各年龄组合并危险因素比较,X2=14.972,P=0.010。结论以36~55岁年龄段的无症状性脑血管狭窄检出率较高,且随着年龄的增高男性发生率较女性高、合并脑血管危险因素更多见,所检出的问题血管主要是前循环,以大脑中动脉和颈内动脉终末端最为多见,各年龄段的狭窄血管无明显差异,各年龄组合并危险因素差异有统计学意义。
Objective To screen for possible intracranial vascular stenosis in healthy population by color transcranial doppler (TCD), in order to intervene early and reduce the incidence of cerebrovascular disease. Methods Delekai EMS-9PB color transcranial Doppler ultrasound system for testing. Results In 36-55 years old, with hypertension, diabetes, hyperlipidemia, TCD prompted intracranial vascular stenosis is more common. X2 = 4.584, P = 0.469; Compared with the stenosis of MCA and / or TICA in each age group, X2 = 3.320, P = 0.651; X2 = 14.972, X2 = 14.972, P = 0.010. Conclusions The detection rate of asymptomatic cerebrovascular stenosis in 36-55 years old is high, and with the increasing of age, the incidence of male is higher than that of female. The risk factors of cerebrovascular disease are more common. Is the anterior circulation, the middle cerebral artery and internal carotid artery terminal most common, stenosis in all age groups no significant difference between the age group and risk factors were statistically significant.
