目的：为脉络丛前动脉与视束病变关系提供形态学基础。方法：用体视显微镜和手术显微镜对１００侧成人脑标本的脉络丛前动脉进行解剖观察，对其中５０～７０岁６０侧脑标本的颈内动脉，脉络丛前动脉做病理组织学观察。结果：脉络丛前动脉９２％起自颈内动脉，是视束血供的主要动脉。观察发现，６０侧标本中颈内动脉管壁内有粥样硬化斑块，纤维斑块及中膜钙化等病变者占８８．３％（５３侧），与颈内动脉相应的脉络丛前动脉内有斑块形成并阻塞管腔者占３．８％（２侧），管腔缩小者占６．７％（４侧）。结论：５０岁以上，突然视力改变，有视野缺损，眼底正常，无视神经萎缩，可能是脉络丛前动脉的病变所致。
OBJECTIVE: To provide a morphological basis for the relationship between the choroid plexus artery and optic tract lesions. Methods: The anatomic observation of the choroid plexus of 100 adult brain specimens was performed with stereomicroscope and surgical microscope. Pathological examination was performed on the internal carotid artery and the choroid plexus anterior cerebral artery in 60 to 50-year-old adult. Results: 92% of the choroid plexus anterior artery originated from the internal carotid artery, which is the main artery of the blood supply to the optic tract. Observations found that in 60 specimens of internal carotid artery wall in atherosclerotic plaque, fibrous plaque and calcification and other lesions accounted for 88.3% (53 sides), and the internal carotid artery corresponding choroidal plexus artery There were 3.8% (2 sides) of the plaques forming and occluding the lumen, 6.7% (4 sides) of the lumen narrowing. Conclusion: Over 50 years of age, a sudden change of visual acuity, visual field defect, normal fundus, ignoring nerve atrophy may be due to choroid plexus anterior artery lesions.
