Abstract
PURPOSE: To identify anterior spinal artery (ASA) infarct or occlusion by CT angiography (CTA) in patients with cervical spondylotic myelopathy (CSM). METHODS: Fourteen patients with CSM were performed CTA of ASA after admission. T2-weighted hyperintensity of MR image was compared with image of CTA of ASA. RESULTS: All patients presented spinal canal sagittal diameter compression from 10 to 80% and different T2-weighted hyperintensity of MR images. No ASA infarct or occlusion was found in CSM patients. CONCLUSION: ASA infarct or occlusion is not commonly seen in CSM patients with spinal canal sagittal diameter compression less than 80%. Pathological changes about T2-weighted hyperintensity of MR image in CSM have no close correlation with ASA infarct.
