A patient suffering for an ischemic "locked-in" syndrome following a subarachnoid hemorrhage, was evaluated with brain stem acoustic evoked potentials (BAEPs), short latency somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs). Neuroradiological findings failed to reveal any lesion in the brain stem, while a transcranial Doppler showed increased flow velocity upon the basilar artery, suggesting vascular spasm. BAEPs were normal and SEPs showed to be slightly impaired while MEPs upon magnetic cortical stimulation were heavily deranged. Neurophysiological investigations appeared remarkable for the early diagnosis of the disease, when neuro-radiological findings were still negative.
一名蛛网膜下腔出血后患有缺血性“闭锁综合征”的患者,接受了脑干听觉诱发电位(BAEP)、短潜伏期体感诱发电位(SEP)和运动诱发电位(MEP)评估。神经放射学检查结果未发现脑干有任何病变,而经颅多普勒显示基底动脉血流速度增加,提示血管痉挛。BAEP正常,SEP略有受损,而磁皮层刺激时的MEP严重紊乱。当神经放射学检查结果仍为阴性时,神经生理学检查对该疾病的早期诊断显得尤为重要。
