由于辅助运动区(SMA)发作持续时间短,传播速度快,因此很难确定其发作区(SOZ)和传播途径。在此,我们采用近红外光谱(NIRS)和皮质电图(ECoG)同时记录脑肿瘤患者的SMA癫痫发作,研究了其临界脑血流变化、癫痫发作电活动和临床体征。从同侧SMA的SOZ观察到脑血流量增加,并扩散到同侧运动前皮层、同侧感觉运动皮层和对侧半球。这些繁殖模式与脑电图发作活动和临床症状一致。切除SOZ和周围区域,在那里发现了更高的血流量和更高的频率振荡,为该患者取得了良好的结果。我们的初始NIRS-ECoG技术在检测SOZ和癫痫传播方面具有鲁棒性和实用性。
The seizure onset zone (SOZ) and propagation pathways in supplementary motor area (SMA) seizures are difficult to identify because of the short duration and swift propagations of this seizure type. Herein, we studied ictal cerebral blood flow changes, seizure electrical activities, and clinical signs employing simultaneous near-infrared spectroscopy (NIRS) and electrocorticography (ECoG) recordings in a brain tumor patient with SMA seizures. Increased cerebral blood flow was observed from the SOZ in the ipsilateral SMA and spread to the ipsilateral premotor cortex, ipsilateral sensorimotor cortex, and also the contralateral hemisphere. These propagation patterns were concordant with ictal ECoG seizure activities and clinical signs. Removal of the SOZ and surrounding areas, where the higher blood flow and higher frequency oscillations had been identified, achieved a good outcome for this patient. Our ictal NIRS-ECoG technique is robust and useful for detecting the SOZ and seizure propagations.
