著者根据迄至1974年的近代资料,对脑血管供血不足的外科治疗进行评价,并对手术适应症提出看法。颈动脉狭窄对内科医生说来,在病人的颈动脉分叉区偶然发现杂音是一个常遇见的问题。几乎所有这样的病人,其内颈动脉有50%或更多的狭窄。也有少数狭窄是在颈总或颈外动脉。延续到舒张期的杂音常伴随有最严重的狭窄,但杂音的强度并不是狭窄严重程度的可 Based on recent literature up to 1974, the authors evaluated the surgical treatment of inadequate cerebrovascular insufficiency and put forward their views on surgical indications.

Almost all such patients have a 50% or more stenosis of the internal carotid artery. There are also a few stenoses in the total or external carotid artery.
