颈动脉供血不足是指由于颈动脉内壁粥样硬化所造成的管腔狭窄或阻塞,动脉灌注压不足,以及由此而导致的一系列眼和脑部的临床改变。早在1968年Thornas willis 已从病理上对本病作过描述,以后虽有些学者对此病进行观察研究,但因检盘方法落后,使本病的临床诊断率受到很大限制。1936年Sjogvist 应用血管造影法,在活体上证实了颈动脉阻塞的存在,引起人们对本病进行深入研究的兴趣,从而对其临床表现,伴随症 Carotid insufficiency refers to a series of ocular and cerebral clinical changes caused by inadequate arterial perfusion pressure due to stenosis or occlusion of the lumen caused by atherosclerosis of the carotid artery. As early as 1968, Thornas willis has described the pathology of the disease, though some scholars after the observation and study of the disease, but because of the method of inspection laggards, so that the clinical diagnosis of the disease is subject to great limitations. 1936 Sjogvist angiography, in vivo confirmed the existence of carotid artery occlusion, causing people to further study of the disease of interest, so its clinical manifestations, with accompanying disease
