The anomalous origin of a hypoplastic Left Vertebral Artery (LVA) from the aortic arch is a rare anatomic variant. This study discusses the case of a patient with a C1 lateral mass tumor that surrounded a dominant Right Vertebral Artery (RVA) according to preoperative computed tomography angiography, with a hypoplastic LVA originating from the aortic arch. Surgery was performed, and the patient recovered uneventfully. To date, no study has reported the simultaneous association of two variations (origin and diameter) in the LVA. A deep understanding of abnormalities in the diameter and origin of LVA is a must for neurosurgeons as well as for thoracic and vascular surgeons to conduct surgical procedures.
发育不全的左椎动脉（LVA）起自主动脉弓是一种罕见的解剖变异。本研究讨论了一名患者的病例，根据术前计算机断层血管造影，其C1侧块肿瘤包绕优势右椎动脉（RVA），左椎动脉发育不全且起自主动脉弓。患者接受了手术，术后恢复顺利。迄今为止，尚无研究报道左椎动脉同时存在两种变异（起源和直径）的情况。神经外科医生以及胸外科和血管外科医生在进行手术时，必须深入了解左椎动脉直径和起源的异常情况。
