Arteria radicularis

Spinal cord

infarction presenting as Brown-Séquard syndrome from spontaneous vertebral artery dissection: a case report and literature review. Spinal cord arerial supply. The arteries supplying the spinal cord include the anterior spinal artery (ASA), the posterior spinal artery (PSA), and the radicular artery. The upper region (C1-T2 segments) of the spinal cord is supplied mainly by the vertebral artery. Starting at the level of C3, the anterior and posterior spinal arteries receive a branch from the vertebral artery, that of the radicular artery. In our case, the basic lesion of this patient is the occlusion of the cervical radicular artery caused by vertebral artery dissection, which eventually resulted in right spinal cord infarction
