Cervical spondylotic myelopathy patients with prior cerebral infarction: Clinical characteristics, surgical outcomes and prognostic value of “prior cerebral infarction”

Rapid progressive myelopathy with advanced neurological impairment and “intramedullary T2-weighted hyperintensity” are common in patients with CSM and prior CI. Surgical outcomes in these patients are poorer than those of ordinary CSM patients. “Prior CI” is a risk factor for predicting poor surgical outcomes.
