Electroencephalographic monitoring of a patient during carotid endarterectomy demonstrated severe ipsilateral voltage suppression with preservation of rhythms when the common carotid artery was clamped. Because the atheromatous plaque extended almost to the base of the skull, it was impossible to insert a shunt. Occlusion time was 19 minutes. After carotid flow was re-established, there was a rapid recovery of voltage. The patient awoke with a profound hemiparesis, but this cleared almost completely within a week. The EEG changes indicated severe ischemia, but, though function was transiently impaired, there was no apparent cerebral necrosis. This case represents the most severe yet reversible episode of ischemia during carotid clamping reported to date. Preservation of EEG rhythms, even in the face of voltage suppression, may have been a favorable sign.
在颈动脉内膜切除术期间对一名患者进行脑电图监测显示，当颈总动脉被夹闭时，同侧出现严重的电压抑制，但节律得以保留。由于动脉粥样硬化斑块几乎延伸至颅底，无法插入分流管。阻断时间为19分钟。恢复颈动脉血流后，电压迅速恢复。患者苏醒时伴有严重偏瘫，但在一周内几乎完全恢复。脑电图变化表明存在严重缺血，尽管功能暂时受损，但未出现明显的脑坏死。该病例代表了迄今为止报道的颈动脉夹闭期间最严重但可逆的缺血发作。即使存在电压抑制，脑电图节律的保留可能是一个有利迹象。
