本文对47例腔隙性脑梗塞进行了临床与CT分析。CT扫描共发现71个梗塞灶,其中46个与临床症状和体征相符,无症状病灶25个,占35.2%。纯运动偏瘫24例,感觉运动性中风19例,共济失调性偏瘫4例。3组间的发病危险因素、功能缺损分布和病灶平均体积未见有明显区别,神经功能缺损均不严重,预后较好。本文资料提示高血压、糖尿病、心脏病及血液高凝状态可能是腔隙性脑梗塞发病的危险因素。 In this paper, 47 cases of lacunar infarction were analyzed by clinical and CT. A total of 71 infarct lesions were found on CT scan, 46 of which were consistent with clinical symptoms and signs. There were 25 asymptomatic lesions, accounting for 35.2%. 24 cases of pure motor hemiplegia, 19 cases of sensory stroke, 4 cases of ataxia hemiplegia. There was no significant difference between the three groups in the incidence of risk factors, the distribution of functional impairment and the average volume of lesions, neurological deficits were not serious, the prognosis is good. The data suggest that hypertension, diabetes, heart disease and hypercoagulability may be the risk factors of lacunar infarction.
