毫针蝶骨电极脑电图诊断癲痫62例体会

本文将强直一阵挛性发作6例,复杂部分性发作30例,间脑性发作26例,共62例毫针蝶骨电极脑电图与头皮电极脑电图做了统计比较,结果阳性率提高16.1%,但定位定侧率却提高32.2%,尤其在背景脑电图异常的基础上更有意义,仍以复杂部分性发作的阳性率及定位定侧率最高。对间脑性发作申的头痛型3例,腹痛型、呕吐型、肢冷型各1例,加用蝶骨电极后均能显示一侧或两侧颞区局灶性放电,敌对该类癫痫的诊断及确定继发还是原发性发作,毫针蝶骨电极亦具有重要价值。

Preliminary Report of 62 Cases on Diagnosis Epileptic with EEG of Acupunctural Sphenoidal Electrode

Sixty two electroencephalograms(EEG)of epilepsies reorded by acupunctural sphenoidal and scalp epectrodos were reviewed;including geneialized tomic-chonic seizures in 6 cases,Psychomotor seizures in 30,autonomic seizures in 26.The EEG of acupunctural sphenoidal electrodes were analysed and compared with scalp electrodes. The features of these EEG were asfollow:The incidence of positive EEG raised 16.1% in acupunctural sphenoidal electrodes,The rate of determining the posetion and side of brain focus was incrensed by 32.2% over scalp electrodes. Psychomotor seizures were detected the most. All 6 cases of automotor seizures in acupunctural sphenoidal electrodes were picked up the local discharges in unilateral or bilateral. Thus EEG of acupunctural sphenoidal electrodes for the diagnosis of autonomic seizures were of ereat worth.
