Abstract

A 56-year-old man was referred for digital subtraction angiography (DSA) with an ultrasound diagnosis of right proximal internal carotid artery (ICA) stenosis for possible carotid artery stenting. DSA revealed total occlusion of the ICA and an occipital artery arising from the stump and simulating continuation of the ICA. An ascending pharyngeal artery also arose from the same occipital artery. This case is of interest because this is a rare variation besides being a cause of misdiagnosis at carotid ultrasound.

摘要

一名56岁男性因超声诊断为右侧颈内动脉（ICA）近端狭窄，可能需要进行颈动脉支架置入术，故而接受数字减影血管造影（DSA）检查。DSA显示颈内动脉完全闭塞，枕动脉从残端发出，形似颈内动脉的延续。咽升动脉也起自同一枕动脉。该病例值得关注，因为这不仅是一种罕见的变异情况，还会导致颈动脉超声误诊。
