We report a case of variant origin of superior thyroid artery (STA), occipital artery (OA) and ascending pharyngeal artery (APA) from the cervical segment of internal carotid artery (ICA) in a 63-year-old male patient, who presented with acute subarachnoid hemorrhage. Four-vessel angiography showed asymptomatic occlusion of ICA giving origin to the anomalous branches. There was common origin of the STA and the OA. The APA originated from the OA. We did not find any other description in the literature on variant origin of STA from the cervical segment of ICA in the presence of a well-developed external carotid artery.
我们报告了一例63岁男性患者，其甲状腺上动脉（STA）、枕动脉（OA）和咽升动脉（APA）起源变异，均发自颈段颈内动脉（ICA），该患者出现急性蛛网膜下腔出血。四血管造影显示，发出异常分支的颈内动脉无症状性闭塞。甲状腺上动脉和枕动脉共同起源。咽升动脉起源于枕动脉。在文献中，我们未发现其他关于在颈外动脉发育良好的情况下，甲状腺上动脉起源于颈段颈内动脉的变异描述。
