A case of visual disturbance by embolization through the external carotid artery (ECA) after internal carotid artery (ICA) occlusion is reported. A 65-year-old female presented left ICA occlusion 14 years ago. She was admitted with acute deterioration of left visual acuity. Ophthalmologically, the retinal central artery was occluded. Cerebral angiography disclosed an irregular wall at the left ICA stump and stenosis of the maxillary artery. Carotid endarterectomy of the common carotid artery, ECA and residual ICA was performed and atheromatous plaque with ulceration was removed. The postoperative course was uneventful. We discuss cases of ICA occlusion in relation to visual impairment.
报告了1例颈内动脉（ICA）闭塞后经颈外动脉（ECA）栓塞导致视力障碍的病例。一名65岁女性14年前出现左侧ICA闭塞。她因左眼视力急剧下降入院。眼科检查显示视网膜中央动脉闭塞。脑血管造影显示左侧ICA残端管壁不规则，上颌动脉狭窄。对颈总动脉、ECA和残余ICA进行了颈动脉内膜切除术，切除了伴有溃疡的动脉粥样斑块。术后过程顺利。我们讨论了与视力损害相关的ICA闭塞病例。
