症状性颈总动脉闭塞(存储)是罕见的。我们研究17缺血性脑血管患者症状和单边存储在血管摄影帮助澄清临床和影像学特征。平均年龄是62岁;65%是女性。主要的症状和体征包括visual-ipsilateral单眼或retrochiasmal症状(88%)、电动机的弱点(88%)、感觉障碍(59%)、眩晕或头晕(53%),和晕厥(24%)。构音障碍、头痛或无意识的肢体发生震动的频率更低。定位相关症状发生在大约有三分之二的病人。tia通常是多个中风和中风或发生之前没有后续的82%。半球tia侧存储发生在41%。10例(59%)遭受了中风,其中7例(70%)同侧的存储。 Vascular risk factors included cigarette use (76%), hypertension (71%), diabetes mellitus (41%), and hyperlipidemia (41%); 82% had two or more risk factors. Known cardiac disease was present in 59%. CCAO was present at the origin of the vessel in most patients. Most had atherosclerotic narrowing of multiple extracranial large vessels. During follow-up, none of the patients had a spontaneous second infarct; five had TIAs, including two with amaurosis fugax, all in the CCAO territory. More restricted external carotid collaterals may, in part, explain the higher frequency of ipsilateral stroke and contralateral TIAs than reported for internal carotid occlusion.
