During routine cadaveric dissection of a 77-year-old male, a series of unique arterial variations were observed within the left anterior cervical region. Firstly, the ascending pharyngeal artery (APA) was observed branching from the common carotid artery (CCA), between the internal (ICA) and external carotid (ECA) arteries. The APA continued superiorly without branching, as is typical for APA. Secondly, a common arterial trunk was observed emerging from the posterior cervical segment of the left ICA. As the common trunk continued superiorly, it bifurcated into two distinct branches. The first branch terminated as several muscular branches (MB) feeding the salpingopharyngeus and superior constrictor muscles. The second branch, a suspected neuromeningeal trunk (NMT), continued superiorly and terminated within the jugular foramen. We believe this individual presented with atypical branching of the APA system. The course of both the muscular branch and the neuromeningeal trunk were novel in that they both originated from a common trunk off the ICA. Both variations could have pathologic and clinical implications.
在对一名77岁男性进行常规尸体解剖时，在左颈前区观察到一系列独特的动脉变异。首先，观察到咽升动脉（APA）从颈总动脉（CCA）分出，位于颈内动脉（ICA）和颈外动脉（ECA）之间。咽升动脉如通常情况一样继续上行且无分支。其次，观察到一条总动脉干从左颈内动脉的颈后段发出。当总动脉干继续上行时，它分成两个不同的分支。第一分支以数条肌支（MB）终支，这些肌支为咽鼓管咽肌和咽上缩肌供血。第二分支，一条疑似神经脑膜干（NMT），继续上行并在颈静脉孔内终支。我们认为该个体存在咽升动脉系统的非典型分支。肌支和神经脑膜干的走行都很独特，因为它们都起源于颈内动脉发出的一条总动脉干。这两种变异都可能具有病理和临床意义。
