Carotid artery dissections are commonly associated with trauma or various connective tissue disorders. Dissection of the cerebrovascular arteries can result in ischemic stroke and is a frequent stroke etiology in younger patients. Anatomical variants of aortic arch branching, such as the 'bovine' aortic arch, are assumed to have little or no physiological consequence. To the best of our knowledge, we present for the first time a case of spontaneous dissection of the common origin of the innominate and left common carotid artery in a bovine aortic arch, resulting in bilateral dissection of the carotid arteries.
颈动脉夹层通常与创伤或各种结缔组织疾病有关。脑血管动脉夹层可导致缺血性中风，是年轻患者中风的常见病因。主动脉弓分支的解剖变异，如“牛”主动脉弓，被认为几乎没有或没有生理影响。据我们所知，我们首次报告了一例牛主动脉弓无名动脉和左颈总动脉共同起源处的自发性夹层，导致双侧颈动脉夹层。
