Abstract

Background: A common carotid artery occlusion (CCAO) is very rare and the clinical features of CCAO have rarely been described. Since the blood supply of the eye and orbit is derived from the internal carotid artery, a CCAO may present with various ophthalmological symptoms, ranging from incidental findings to complete visual loss but also other neuro-ophthalmological abnormalities.

Case report: A 61-year-old woman presented with acute monocular vision loss and an elevation deficit of the right eye. Fluorescein angiography showed delayed filling of both the retinal and choroidal vasculature, without occlusion/embolisms of the retinal arteries. Vascular imaging showed a right CCAO.

Conclusion: CCAO has a variable presentation. In patients with acute unilateral visual loss a CCAO should be considered, especially when ocular motility deficits are present. Fluorescein angiography examination can aid in the localization and diagnosis of the vascular insult. Urgent referral for a systemic work-up is essential.

颈总动脉闭塞的罕见表现。

背景：颈总动脉闭塞（CCAO）非常罕见，其临床特征也鲜有描述。由于眼部和眼眶的血液供应来自颈内动脉，颈内动脉闭塞症可能会出现各种眼科症状，从偶然发现到完全失明不等，而且还会出现其他神经眼科异常：病例报告：一名 61 岁的妇女因急性单眼视力下降和右眼视力下降而就诊。荧光素血管造影显示视网膜和脉络膜血管充盈延迟，视网膜动脉无闭塞/栓塞。血管造影显示右眼有CCAO：结论：CCAO 的表现多种多样。对于急性单侧视力丧失的患者，尤其是出现眼球运动障碍时，应考虑 CCAO。荧光素血管造影检查有助于血管损伤的定位和诊断。必须紧急转诊进行系统检查。
