We studied the frequency and clinical consequences of vertebral artery injuries and the relationship between the type of vertebral artery injury and bone abnormalities in patients with acute cervical spine trauma. One hundred and eleven patients who had acute nonpenatrating cervical spine trauma were examined with MR angiography and/or 3D-CT angiography, within 24 hours after the injury. From findings of MR angiography and/or 3D-CT, we classified vertebral artery injury as "displacement", "stenosis" and "occlusion". Findings concerning the vertebral artery in MR angiography and/or 3D-CT angiography demonstrated abnormalities in 22 patients (19.8%). 5 of the cases (4.5%) had displacement of the vertebral artery, 7 cases (6.3%) had stenosis and 10 cases (9.0%) had occlusion of the vertebral artery. Patients without bone dislocation had no vertebral artery injuries. Patients with bone displacement had a high incidence (71.0%) of vertebral artery injury. Neurological deficits due to ischemia of the brain appeared in 5 cases (16.1%). We should consider the possibility of vertebral artery injury especialy in patients with subluxation or dislocation of the cervical spine.
