A 56-year-old woman was admitted to our hospital because of amaurosis fugax. The carotid angiogram showed irregularly stenotic lesions of the left and right internal carotid arteries (ICAs), suggestive of dissection. Follow-up evaluation was performed by transoral carotid ultrasonography (TOCU) with contrast enhancement (CE), which yielded better vessel lumen and intramural hematoma visualization than color Doppler imaging. CE-TOCU is useful for evaluating ICA dissections that extends to the high cervical portion.
一名56岁女性因一过性黑矇入住我院。颈动脉血管造影显示左、右颈内动脉（ICA）有不规则狭窄病变，提示动脉夹层形成。采用经口颈动脉超声检查（TOCU）并进行对比增强（CE）进行随访评估，其对血管腔和壁内血肿的显示比彩色多普勒成像更好。CE-TOCU对于评估延伸至高位颈椎段的ICA夹层很有用。
