摘要
目的 探讨急性缺血性脑卒中患者脑电生理变化和CT成像的临床意义。方法对56例发病后即刻入院的缺血性脑卒中患者检测的CT、脑电图（EEG）、脑电地形图（BEAM）、体感诱发电位（SEP）、经颅磁刺激运动诱发电化（MEP）和神经功能缺损评分（MESSS）及口常生活能力评分（BI）情况进行对比研究及相关分析，结果EEG局限性异常与CT显示病变位置基本一致，但病灶范围存在一定差异：自身患／健侧SEP和MEP比较差异有统计学意义（P〈0．05）。入院不同时间MESSS与入院第28天BI值分析显示两者呈正相关（r=0．58．P〈0．05）．结论 CT成像与脑电生理检查在缺血性脑脑卒中急性期具有较高的早期诊断价值。
Objective To explore the clinical significance of EEG and CT presentations in the patients with acute ischemic stroke. Methods Fifty-six consecutive patients with acute ischemic stroke admitted immediately after the onset were enrolled in this study. The findings by CT, EEG, brain electrical activity mapping （BEAM）, examinations of somatosensory evoked potentials （SEPs） and motor evoked potentials （MEPs） to transcranial magnetic stimulation, and the scores of modified Edinburgh-Scandinavia stroke scale （MESSS） and Barthel Index （BI） were comparatively analyzed in these patients. Results The location of the cerebral foci with EEG abnormalities were basically consistent with the lesions indentified by CT, but the range of the lesions defined by the two modalities showed some discrepancies. There was statistically significant difference in SEP and MEP between the injured and uninjured sides （P〈0.05）. There was a positive correlation between MESSS on admission and BI on day 28 in hospital （r=0.58,P〈0.05）. Conclusion CT and cerebral electrophysiological examination provide valuable assistance in early diagnosis of acute ischemic stroke.
