A 76-year-old man was admitted because of visual loss in his right eye, and was diagnosed with central retinal artery occlusion. Brain MRI revealed asymptomatic acute infarctions in the right middle cerebral artery territory. The proximal right internal carotid artery had migrated into a retropharyngeal location, presenting a 50% stenosis with calcified plaques, and was compressed by the hyoid bone and thyroid cartilage during swallowing on dynamic 3D-CT angiography. Partial resection of the hyoid bone and thyroid cartilage was performed and the postoperative course was uneventful. This case supports the utility of dynamic 3D-CT angiography during swallowing for diagnosing hyoid bone or thyroid cartilage compression-induced thromboembolism.
一名76岁男性因右眼视力丧失入院，被诊断为视网膜中央动脉阻塞。脑部磁共振成像显示右侧大脑中动脉区域有无症状急性梗死。右侧颈内动脉近端移至咽后位置，有50%的狭窄并伴有钙化斑块，动态三维CT血管造影显示吞咽时被舌骨和甲状软骨压迫。对舌骨和甲状软骨进行了部分切除，术后过程顺利。该病例支持吞咽时动态三维CT血管造影在诊断舌骨或甲状软骨压迫引起的血栓栓塞方面的作用。
