Abstract：
Aberrant origin of the vertebral artery is a rare case. Due to its important clinical significance during operations in the superior mediastinum and the root of the neck, the variations of this artery should be clarified, and any cadaveric case should be explored specifically if accompanied by any vascular problem. In this cadaveric case, the embalmed male cadaver was found to have a pacemaker wire inserted in the heart through the superior vena cava, denoting a vascular incompetence due to sinus arrhythmia. The left vertebral artery was found to originate from the aortic arch, positioned between the left common carotid artery and the left subclavian artery. It traveled upward behind the left common carotid artery, passing in front of the stellate ganglion and the ventral rami of cervical spinal nerves before entering the left foramen transversarium of the C6 vertebra. This atypical left vertebral artery, which had an unusual origin from the arch of aorta, was distinct from the right vertebral artery, that typically arises from the right subclavian artery. Also, the left atypical artery was found to be narrower and longer than the right one. Additionally, the left common carotid artery exhibited an unusual origin from the beginning of the brachiocephalic trunk. The present case report would be of significance for vascular surgeons in designing surgical intervention in the root of the neck and for clinicians responsible for monitoring patients with variant vertebral arteries to effectively manage potential vascular complications.
摘要：
椎动脉起源异常是一种罕见的情况。由于其在上纵隔和颈根部手术中的重要临床意义，这条动脉的变化应该被澄清，如果任何尸体病例伴有任何血管问题，都应进行专门调查。在这个尸体案件中,经过防腐处理的男性尸体被发现有一根起搏器导线通过上腔静脉插入心脏，表示窦性心律失常导致的血管功能不全。发现左椎动脉起源于主动脉弓，位于左颈总动脉和左锁骨下动脉之间。它在左颈总动脉后面向上移动,在进入C6椎骨的左孔横区之前，经过星状神经节和颈脊神经的腹支。这个不典型的左椎动脉,起源于主动脉弓，与右椎动脉不同，通常来自右锁骨下动脉。此外，发现左侧非典型动脉比右侧狭窄且长。此外,左颈总动脉从头臂干开始就表现出不寻常的起源。本病例报告对于血管外科医师设计颈根外科干预措施以及负责监测椎动脉变异患者的临床医师有效管理潜在的血管并发症具有重要意义。
