The relationships between transient cerebral and retinal ischemic symptoms and brachiocephalic angiographic findings were studied in 464 patients. The arterial abnormalities were more often bilateral than the symptoms suggested. Normal angiographic appearances were common, although abnormal arteries in patients without related symptoms were also common. When stenosis of the carotid system was 75 per cent or more, there was a strong correlation with symptoms.
对464例患者的短暂性脑缺血和视网膜缺血症状与头臂血管造影结果之间的关系进行了研究。动脉异常双侧出现的情况比症状提示的更为常见。血管造影表现正常的情况很常见，尽管无症状患者中出现异常动脉的情况也很常见。当颈动脉系统狭窄达75%或更高时，与症状有很强的相关性。
