In a group of 99 patients with unilateral or bilateral carotid artery loop the data in case records were analysed. In 11 cases no abnormalities were found, apart from the presence of carotid loop, that could be related to the presence of symptoms of cerebrovascular insufficiency observed in them. In 7 of them these symptoms appeared before the age of 40 years. Frequently, the appearance of symptoms was preceded by headaches and 6 patients had episodes of transient cerebral ischaemia. On lateral angiograms during lateral rotation of the head in 9 cases kinking of the arterial wall was seen which had been not observed in the anteroposterior projection. It is thought that in a small group of patients carotid loop may be the cause of cerebrovascular failure.
在一组99例单侧或双侧颈动脉袢患者中，对病历数据进行了分析。11例除存在颈动脉袢外未发现与他们所观察到的脑血管供血不足症状相关的异常。其中7例这些症状出现在40岁之前。症状出现前常伴有头痛，6例有短暂性脑缺血发作。在9例患者头部侧转时的侧位血管造影中，可见动脉壁扭结，而在前后位投影中未观察到。据认为，在一小部分患者中，颈动脉袢可能是脑血管功能衰竭的原因。
