项目摘要

We performed EEG with intravascular electrodes (intravascular EEG) as a presurgical extracranial study during the Wada procedure to detect the epileptiform discharges originating specifically from the temporal lobe(TLE). In this study of nine patients with temporal lobe epilepsy, we evaluated the usefulness of this technique for comparison with a simultaneously recorded scalp EEG, furthermore with the results of chronic intracranial EEG recordings.The subjects in this study were 9 patients with medically intractable TLE. After giving informed consent, we placed intravascular electrodes into bilateral middle meningeal artery at the level of the for amen spinosum, placing the electrodes to the inferior surface of each temporal lobe. The intravascular EEG was recorded for about one hour while scalp EEG with sphenoidal (SP) electrodes was simultaneously recorded.The intravascular EEG demonstrated clear epileptiform discharges, sometimes even when they were absent on the simultaneously reco … More rded scalp EEG. As for the lateralization of the epileptiform discharges recorded from intravascular EEGs, in 6 of 9 patients, the epileptiform discharges were observed only at the unilateral intravascular electrode which lateralization was agreed with that of the ictal patterns obtained from subsequent intracranial recordings. In 2 patients, although epileptiform discharges were demonstrated bilaterally, most of the epileptiform discharges were predominantly observed at the unilateral intravascular electrode. In the remaining 1 case intravascular EEG revealed bilateral epileptiform discharges, however, the ictal patterns from intracranial EEG also showed bilaterally. The intravascular EEG agreed with lateralization of epileptiform discharges obtained from subsequent intracranial recordings.This intravascular EEG can detect the epileptiform discharges more sensitive than SP electrode. Although the duration of recording is limited, intravascular EEG appears to be useful because it can be performed easily, safely and relatively painlessly in the course of angiography. Less

在WADA手术中，我们用血管内电极(血管内EEG)进行了脑电检查，作为一项术前颅外研究，以检测特定起源于颞叶(TLE)的癫痫样放电。在这项对9名颞叶癫痫患者的研究中，我们评估了这项技术的有效性，并与同时记录的头皮EEG，以及慢性颅内EEG记录的结果进行了比较。在给予知情同意后，我们在棘门水平的双侧脑膜中动脉放置血管内电极，将电极放置在每个颞叶的下侧表面。血管内脑电记录约1小时，同时记录有蝶骨(SP)电极的头皮脑电。血管内脑电显示清晰的癫痫样放电，有时甚至在同时记录…上没有癫痫样放电更多的头皮脑电波。至于血管内脑电记录的癫痫样放电的偏侧化，9例患者中有6例仅在单侧血管内电极上观察到癫痫样放电，其偏侧化与随后的颅内记录所获得的发作模式一致。在2例患者中，虽然双侧都有癫痫样放电，但大部分癫痫样放电主要发生在单侧血管内电极上。另1例血管内EEG显示双侧癫痫样放电，但双侧颅内EEG也显示癫痫样放电。血管内EEG与随后的颅内记录所获得的癫痫样放电的定侧化相一致，这种血管内EEG能比SP电极更敏感地检测到癫痫样放电。虽然记录的时间有限，但血管内脑电似乎是有用的，因为它可以在血管造影过程中轻松、安全和相对无痛地进行。较少
