脑的动脉血供来自左、右颈动脉和左右椎动脉。这4支主干动脉在颅内互相吻合,形成基底动脉环。按其解剖部位,可以将颈动脉和椎一基底动脉分成颅内、颅外和主动脉弓起始部三段。虽然这三个解剖部位都可以发生阻塞性病变,继而引起脑缺血,但以颅外动脉

Cerebral arterial blood supply from the left and right carotid artery and left and right vertebral artery. The four main arteries in the intracranial anastomosis, the formation of basilar artery ring. According to its anatomical site, the carotid artery and vertebral-basilar artery can be divided into three sections, the cranial, the extracranial and the aortic arch. Although all three anatomical sites can develop obstructive lesions, which in turn cause cerebral ischemia, the extracranial artery
