The EEG was recorded using an endovascular guide wire as the electrode. This was Teflon coated except for its terminal portion, which was placed distal to the origin of the middle cerebral artery. Four hemispheres were sampled sequentially in two patients with intractable complex partial seizures who were undergoing routine preoperative carotid amytal assessment. Epileptiform spikes were detected in one patient, concordant with decreased hippocampal volume on MRI and scalp EEG changes. Endovascular EEG during the amytal procedure is less invasive than other intracranial EEG methods and may develop a role in preoperative assessment of selected patients with intractable epilepsy.
脑电图记录使用血管内导丝作为电极。除其末端部分外，该导丝涂有特氟龙，末端部分置于大脑中动脉起始部的远端。在两名正在接受常规术前颈动脉阿米妥评估的难治性复杂部分性癫痫患者中，依次对四个脑半球进行采样。在一名患者中检测到癫痫样棘波，这与MRI上海马体积减小和头皮脑电图变化一致。阿米妥注射过程中的血管内脑电图比其他颅内脑电图方法侵入性小，可能在难治性癫痫患者的术前评估中发挥作用。
