Combined EEG and brain CT examinations were performed in 33 patients during the 1st and 2nd week after stroke. CT was abnormal in 17 patients (51%) and EEG was abnormal in 24 patients (72%). In 17 patients CT and EEG showed conflicting results; in 5 patients with normal EEG findings CT was pathological, and 12 patients had normal CT but pathological EEG findings. In this latter group, there were 5 particularly interesting cases with normal CT and a prominent unilateral EEG abnormality. Recently patients with this combination of findings have been described where further investigations disclosed internal carotid occlusion, which could be treated surgically. It is suggested that EEG should be more extensively used when CT findings are negative after stroke, and if a major unilateral EEG abnormality is encountered in such cases, further investigations with angiography should be considered in order to exclude surgically treatable internal carotid occlusion.
对33例脑卒中患者在发病后第1周和第2周进行了脑电图(EEG)和脑CT联合检查。17例患者(51%)CT检查异常,24例患者(72%)EEG检查异常。17例患者的CT和EEG结果相互矛盾;5例EEG结果正常的患者CT检查呈病理性,12例CT检查正常但EEG结果呈病理性。在后一组中,有5例特别有趣的病例,CT检查正常但EEG出现明显的单侧异常。最近报道了具有这种检查结果组合的患者,进一步检查发现为颈内动脉闭塞,可通过手术治疗。建议在脑卒中后CT检查结果为阴性时更广泛地使用EEG检查,如果在这种情况下遇到明显的单侧EEG异常,应考虑进一步进行血管造影检查,以排除可手术治疗的颈内动脉闭塞。
