The records of 628 patients admitted to the Joint Study of Extracranial Arterial Occlusion with transient symptoms of carotid system ischemic disease were examined to determine the accuracy of predicting disease of the extracranial internal carotid artery on the basis of clinical information alone. A patient with a history of episodes of amaurosis fugax is more likely to have a lesion of the internal carotid artery on the same side than if he were having only transient cerebral ischemic attacks. In patients with transient symptoms and a carotid bruit on the appropriate side, the incidence of an angiographically normal carotid artery was 15%. In those patients with transient symptoms and no palpable pulsation in the cervical region on the appropirate side, the incidence of an angiographically normal carotid artery was zero.
对628例因颈动脉系统缺血性疾病短暂症状而入院接受颅外动脉闭塞联合研究的患者记录进行了检查，以确定仅基于临床信息预测颅外颈内动脉疾病的准确性。有一过性黑矇病史的患者比仅有短暂性脑缺血发作的患者更有可能在同侧出现颈内动脉病变。在有短暂症状且患侧有颈动脉杂音的患者中，血管造影显示颈动脉正常的发生率为15%。在有短暂症状且患侧颈部区域未触及搏动的患者中，血管造影显示颈动脉正常的发生率为零。
