无体征缺血性脑血管病脑电地形图、脑电图CT对比观察

AMONG BEAM EEG CT FOR THE ISCHEMICCEREBROVASCVLAR DISEASES WITHOVETSIGNS OF LOCALIZATION

对临床表现头昏头痛，而无体征的２００例脑梗塞和５０例短暂性脑缺血发作患者进行了脑电地形图、脑电图、ＣＴ对比观察，结果表明：脑梗塞组脑电地形图异常率９０．０％。脑电图异常率６５．６％，ＣＴ异常率９７．５％。短暂性脑缺血发作组检查异常率分别为５８％、３０％、４％。脑梗塞组ＣＴ异常率均高于其它两种检查，而短暂性脑缺血发作组脑电地形图异常率匀高于其它两种检查。因此脑电地形图在早期诊断无体征缺血性脑血管病上有一定临床意义。

The clinical indications of the patients suffering form the diseases feeldizzy and headache. We have made comparisions and observations among their topographic electroencephalography mappings (BEAM ), electroencephalograms (EEG ),and computed tomographys (CT) of the 200 patients who suffered form cerebral infarction(CI) without signs and 50 patients who suffered from transient ischemic attack (TIA),and the results have shown that,for the patients in the group of CI,theis 97. 5%. Whereas for the patinets in the TIA group,the percentages of the abovementioned three are 58%,30% and 4% respectively. The percentage of abnormalityof CT is higher than the other two in the CI group. and the precentage of the abnormality of BEAM is highetr than the other two kinds in the TIA group. There foreBEAM has a specific clinical significance in the early stage diagnosis of ischemiccerebrevascular diseases without signs of localization,and it is worth to be spreadfor application.
