脑动脉硬化对外侧膝状体核(LGN)血供的影响,国内外报道较少。我们以人脑为实验材料,调查LGN的血液来源、微血管构筑和来源动脉的病理变化,结合视野缺损进行探讨。1临床资料本组死者年龄18-80岁。均用甲醛固定人脑100侧(其中成人45侧,胎儿55侧),手术显微镜下观察外侧膝状体动脉来源、数量和分布,绘图记录,游标卡尺测小动脉长度,测微计测小动脉内径。取上述50～70岁成人脑的颈内动脉、大脑后动脉及分支各3-5cm,石蜡包埋,组织切片,HE染色,光镜观察,显微照相。
Cerebral arteriosclerosis on the lateral geniculate nucleus (LGN) blood supply, less reported at home and abroad. We use the human brain as the experimental material to investigate the blood source of LGN, the pathological changes of microvascular architecture and artery origin, and explore the defect of visual field. 1 clinical data of the group aged 18-80 years old. All of them were fixed on 100 sides of human brain (including 45 adults and 55 fetuses) with formaldehyde. The origin, quantity and distribution of the lateral geniculate motor were observed under the operation microscope. The length of the arterioles was measured by vernier caliper. . The carotid arteries, posterior cerebral arteries and branches of the brains from 50 to 70 years old were collected from 3 to 5 cm, embedded in paraffin, sectioned, stained with HE, observed with light microscope and photographed.
