Background:Bilateral thalamus infarction near median line is uncommon in clinic.Reports concerned with this conditions were more less.It is characterized by conscious disorder and Korsakoff syndrome.The main caused may be the injury of intralaminar nuclei,dorsomedial nuclei,and injury of cortical matter,mammalillary bodies,fasciculus thalamicus around cerebral chamer III.Comprehensing the disability characteristics in pateints with bilateral thalamus infarction near median line is important for direction of rehabilitation.While study of survival time will improve evaluation of prognosis. Design:Patients recruited from June 1997～ October 2000 were analyzed. Unit:Intraneural Department of First People's Hospital of Yunnan Province. Subjects:55 subjects with MRI proved bilateral thalamus infarction near median line entered study.These patients included 3 women,2 men(age ranging from 50 to 77 years old,mean age:68.6 years).The period from onset to admission ranged from 5 hours to 2 days.All subejcts experienced acute bilateral thalamus infarction near median line.All had hypertension previously,1 had diabetes,2 had auricular fibrillation. Intervention:All patients received management which was conducted according to protocol for treatment of ischemic cerebrovascular diseases. Patients clinical characteristics were summari-zed and analyzed.Follow up was conducted to determine the survival period. Main evaluation indexes:Survival time and conscious disorder were evaluated. Result:All patients showed different level of conscious disorder.3 cases developed thalamic dementia,2 developed vision numb,In 1 case,condition progressively deteriorated manifesting as moderate coma progressed to deep coma,and bilateral mydriasis.Finally,this patients died of central respiratory and circulatory failure after 8 days.4 cases with favorable prognosis discharged,3 out of them died within 1 year after discharge.Survival subject suffered from reduced memory was followed up till now. Conclusion:Concious or cognitive disorder ,vision bumb are common among patients with bilateral thalamus infarction near median line.Their prognosis are poor.In the current study,the number of case was samll,so further study is needed.
