摘　　要：目的:了解皮质下动脉硬化性脑病(SAE)在中老年知识分子人群中的发生情况,CT特征及与高血压、高血糖、高血脂之间的相关性。方法:经82 6名中老年知识分子体检发现4 6例SAE患者,回顾性分析其特征并与血压、血糖、血脂进行相关分析与评估。结果:本组人群中SAE的发生率5 .5 7%。SAE患者CT平扫显示表现为双侧侧脑室白质区较对称性低密度影,病变边缘模糊,伴有腔隙性脑梗死、脑萎缩征象;血压、血糖是影响本病的主要因素,经过方差分析及多元线性回归分析差异有显著性;随着年龄的增加,其发生率有明显增高的趋势。结论:SAE的主要病因是高血压、高血糖。CT是发现SAE的重要手段之一。Objective To study the incidence of subcortical arteriosclerotic encephalopathy (SAE) in middle-old aged knowledge population,its CT character and therelationship with blood pressure,sugar and lipoids,so as to provide evidence for clinical diagnosis.Methods Analyze the character of 46 cases of SAE patients found during thehealth scans of 826 middle-old aged knowledge population,retrospectively.Compare and evaluate with blood pressure,sugar and lipoids.Results The incidence of SAE in the present group was nearly 5 %.CT plainscan showed that there were symmetrical hypodense shadows withpoorly-defined border,along with the sign of Lacunar infarction、Brain atrophy.Blood pressure and age were the main factors of this disease,there wassignificant difference.The incidence tended to increase along with the age.Conclusion The main reason of SAE is hypertension and high blood sugar.CT is one of the important methods for diagnosis of SAE.Early diagnosis and early treatment are clinically valuable to the outcome of this disease.
