脑血管性痴呆的CT与解剖学研究

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,观察脑梗死的部位和数目。结果 痴呆患者脑内存在单发或多发性梗死灶,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,2处以上病灶38例。结论 特殊部位脑内多发性小梗死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。

CT and Anatomy of the Brain Vascular Dementia

Objective To study the pathologic and anatomical basis of the brain vascular dementia, analysie the diagnosing value of CT for the patents with vascular dementia. Methods 90 patients of brain vascular dementia were examined with CT,the place and the number of the brain infarction were observed. Results The single or plural infarction locuses were found in patient's brain. In these patients, 73 infarction locuses were at the area of basal neuroganglion, 52 cases were at frontal lobe, 46 cases were at temporal lobe, 22 cases were at thalamus, 5 cases were at parietal lobe, 5 cases were at brain stem, 38 cases were above two infarction locuses. Conclusion Small plural infarction locuses 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 u-nique method to clinical diagnosis.
