脉络丛前动脉(旧名脉络膜前动脉)虽然比较细小,却是一支很重要的脑血管,它除了参加形成侧脑室脉络丛外,并发出多数分支分布到颞叶钩回、视束、外侧膝状体、中脑、丘脑、内囊和基底节等结构,在颈内动脉造影的X线片上,它的显影率可高达95％左右。由于脉络丛前动脉所处的特有位置以及比较恒定的走行和分布,在进行脑血管造影时,观察其形态和位置的改变常常是诊断颅内某些疾患的仅有证据。随着国内X线脑血管造影技术的推广和普及,脉络丛前动脉对诊断颅内疾患的意义越来越为放射科、神经外
Although the choroid plexus artery (formerly named anterior anterior choroidal artery) is rather small, it is a very important cerebrovascular. In addition to participating in the formation of the lateral choroid plexus, most of the branches are distributed to the temporal lobe, the optic tract, the lateral knee The body, midbrain, thalamus, internal capsule and basal ganglia and other structures, in the carotid artery angiography X-ray film, its development rate can be as high as 95%. Due to the unique location of the choroidal plexus artery and its relatively constant travel and distribution, observation of changes in its morphology and location during angiography is often the only evidence of diagnosis of certain intracranial conditions. With the promotion and popularization of the domestic X-ray cerebral angiography techniques, the significance of the choroid plexus anterior artery in the diagnosis of intracranial disorders is more and more for radiology, extra-neural
