用 TCD 即经颅多普勒对416例年龄为40～65岁的人进行体检。结果:15%有脑血管狭窄,两根以上血管狭窄的患者做 CT 发现15%有腔隙性脑梗塞;同时本组人群中高血压患者的脑血管狭窄发病率为22%;冠心病(不合并高血压)的脑血管狭窄发病率为14%,这均说明高血压及动脉粥样硬化与脑血管病之间的密切关系。本组各年龄段的脑动脉硬化发病率与文献报道的尸检脑动脉硬化发病率相同。从上述结果可看出 TCD 检查对脑动脉硬化、脑血管狭窄及预测脑中风的价值和实用性。
416 patients aged 40-65 years were examined by TCD transcranial Doppler. Results: Fifteen percent had cerebrovascular stenosis. CT was found in 15% of patients with two or more vascular stenoses with lacunar infarction. At the same time, the incidence of cerebrovascular stenosis was 22% in hypertensive patients in this group. Coronary heart disease Hypertension) has a 14% incidence of cerebrovascular stenosis, both of which indicate the close relationship between hypertension and atherosclerosis and cerebrovascular disease. The incidence of cerebral arteriosclerosis in all age groups in this group is the same as the incidence of cerebral arteriosclerosis in autopsies reported in the literature. From the above results can be seen TCD examination of cerebral arteriosclerosis, cerebral vascular stenosis and prediction of stroke value and practicality.
