脑血管性痴呆的CT与解剖学研究

CT and Anatomical Study of The Brain Vascular Dementia

目的:探讨脑血管性痴呆的病理和解剖学基础,分析CT对脑血管性痴呆的诊断价值。方法:本文对90例符合脑血管性痴呆的患者进行CT检查,观察脑梗塞的部位和数目。结果:痴呆患者脑内存在单发或多发性梗塞灶,其中病灶位于基底神经节区73例、额叶52例、颞叶46例、丘脑区22例、顶叶5例、脑干区5例,二处以上病灶38例。结论:特殊部位脑内多发性小梗塞为脑血管性痴呆的主要原因,CT对脑血管性痴呆的诊断有重要价值,但为非特异性。

Objective:To study the pathologic and anatomical basis of the brain vascular dementia and analyses the diagnosis value of CT for patients with vascular dementia. Methods: 90 patients of brain vascular dementia were examied with CT and the location and the number of the brain infarction were observed. Results:Single or plural infarction loci were found in the patients brain. Of the patients,73 infarction loci were at the area of basal neuroganglion,52 at frontal lobe,46 at temporal lobe,22 at thalamus,5 at parietal lobe,5 at brain stem,ang 38 cases had more than two infarction loci. Conclusion: Small plural infarction loci in special brain area is the main cause of brain vascular dementia. CT examination is important to the diagnosis of brain vascular dementia, but it isn't the unique method to clinical diagnosis.
