title: Injuries to the cervical spine causing vertebral artery trauma: case reports.
abstract: In four patients with lesions of the vertebral artery resulting from cervical spine injury, two were due to unilateral facet dislocation and two to fractures of the dens. There was one arterial occlusion with minor vertebrobasilar symptoms, and an arterial lesion with thrombosis causing embolic occlusion of the basilar artery with lethal outcome. In one patient a fresh fracture of the dens caused dislocation of C1/2 with reversible occlusion of the left and stenosis of the right vertebral artery, resulting in unconsciousness. In a patient with pseudarthrosis of the dens an aneurysm of the vertebral artery could be detected. Cerebellar or cerebral symptoms associated with cervical spine injury should be investigated by vertebral angiography because vertebral arterial injury may be more common than suspected and may simulate traumatic brain damage.
