脑白质疏松与脑梗塞和脑萎缩之间关系的探讨

The Relationship among Leuko-Araiosis Cerebral Infarction and Atrophy or the Brain

探讨脑白质疏松、脑梗塞与脑萎缩合并或独立发生的规律、原因和临床意义。材料与方法：对256树头颅CT显示三者合并或单独存在的住院病人进行回顾性分析，同时找出脑白质疏松和脑萎缩发现率与年龄增长的关系。结果：在脑白质疏松、脑梗塞与脑萎缩中，一病与二病合并率分别为89.6％、65．8％和61．6％，脑白质疏松与脑萎缩合并出现时，轻、中、重程度同步的占53．2％；二者的发现率与年龄增长至高度正相关，γ值分别为0．974和0．972（P＜0．01）。结论：三者的高合并率主要是由于年龄因素和相似的发病危险因素，对发病的差异性提出了一种假说：在相似的病困作用下，由于病变血管发生部位与程度不同，而导致不同的CT表现、因此，在认识和治疗上三者要给予同等的重视。

Purpose: To look into the cause and clinical importance of Leuko-araiosis, cerebral infarc-tion and atrophy of the brain; their mixed and single occurances which lead to their impor-tance. Materials aud Methods :The CT images have been retrospectively analysed in 256 casesof the above mentioned three diseases, by comparing them. To look for the relationship be-tween the incidences of Leuko-araiosis and atrophy of the brain and aging. Results :The mixedrates of one of the three CT images with another two were 89. 6%, 65. 8% and 61. 6%(P<0.01 ), when Leukomaraiosis was mixed with atrophy of the brain, the same degree rateof the two was 53. 2 %. The incidences of cerebral atrophy and Leuko-araiosis were increasedwith aging (γ=0. 974 and γ= 0. 972) (P<0. 01 ). Conclusion:The reason for high mixed ratesof the three diseases was mainly aging and similar risk factors. This paper provides a new hy-pothesis about the differences of the three diseases and their accurances. The different partsand degree of vascular illness result in different CT images. The three CT images, therefore,will be equally considered in recognization and therapy.
