Forty-nine patients with ICA occlusion, who presented without any neurological signs or symptoms, were prospectively followed for an average of 31.2 months. Eight patients (16%) suffered a stroke during follow-up, of which five were within the vascular territory of the occluded artery--5 patients (10%) developed TIAs 4 of which were ipsilateral to the occluded artery. Non-invasive vascular follow-up did not reveal a progression of extracranial arterial disease in the majority of later symptomatic patients. Twenty-three patients (46.9%) died during follow-up, coexisting coronary artery disease being the major cause of death.
49例颈内动脉闭塞患者在无任何神经体征或症状的情况下接受了前瞻性随访，平均随访时间为31.2个月。8例患者（16%）在随访期间发生了卒中，其中5例发生在闭塞动脉的血管供血区内，5例患者（10%）出现了短暂性脑缺血发作（TIA），其中4例与闭塞动脉同侧。大多数后来出现症状的患者经无创血管随访未发现颅外动脉疾病进展。23例患者（46.9%）在随访期间死亡，并存的冠状动脉疾病是主要死因。
