Vertebral artery agenesis is a rare congenital malformation, with few reported cases in the literature and no epidemiological data in the world at this point in time. The importance of diagnosis lies in identifying a potential risk factor for future ischemic events of the posterior circulation, in particular in the young population. It is also important to determine the etiology of chronic headache of unexplained cause that could be attributed to this entity. The present case describes this finding in a 27-year-old female patient with no pathological history, with multiple stab wounds was brought to the emergency room of our hospital .During the study of whether the wounds caused had been penetrating to the neck, a CT angiography was performed. The CT documented an incidental finding of absent left transverse foramen of the cervical vertebrae, absence of the left vertebral artery from its origin in the ipsilateral subclavian artery and a single dolichoectatic right vertebral artery crossing the midline at the entrance to the foramen magnum.
椎动脉缺如是一种罕见的先天性畸形，文献报道的病例很少，目前世界上尚无流行病学数据。诊断的重要性在于识别未来后循环缺血事件的潜在危险因素，尤其是在年轻人群中。确定可能归因于该实体的不明原因慢性头痛的病因也很重要。本病例描述了一名27岁无病史的女性患者的这一发现，该患者因多处刺伤被送往我院急诊室。在研究伤口是否穿透颈部时，进行了CT血管造影。CT记录了一个偶然发现：颈椎左侧横突孔缺如，左侧椎动脉自同侧锁骨下动脉起始处缺如，以及一条单一的迂曲扩张的右侧椎动脉在枕骨大孔入口处 crossing the midline （此处原文有误，推测应为“crossing the midline”，意为“穿过中线”）。
