无症状脑梗塞早期诊断的探讨

A study of early diagnosis on symptomless cerebral infarction

[目的]对比无症状脑梗塞脑电图(EEG)与头颅磁共振(MR)扫描两者之间的符合率。[方法]对204例正常体检者全部进行EEG及MR检查。[结果]发现无症状脑梗塞21例,其中腔隙性梗塞19例,脑叶梗塞2例。高血压及糖尿病性微血管病是主要病因。[结论]EEG“阳性率”与头颅MR扫描结果比较,两者符合率为62.5%。提示EEG对无症状脑梗塞的粗筛具有重要意义。

[ Objective] To compare the coincidence rate between the EEGs（electroencephalo- graph） from patients with symptomless cerebral infarction and their head MRs（ magnetic resonance）. [ Methods] 204 cases of normal examinees are all examined with EEG and MR. [ Results] 21 of the 204 cases have symptomless cerebral infarction, of whom 19 have lacuna infarction and 2 have lobe infarction. The main reason for symptomless cerebral infarction is hypertension, and microangiopathy caused by diabetes mellitus. [ Conclusion] Compared the EEG positive rate and the results of the head MRs, their coincidence rates are beth 62.5%, showing that EEG means much to the fiddle of symptomless cerebral infarction.
