Cortical somatosensory evoked potentials (SSEPs) reflect the functional integrity of somatosensory pathways from the site of stimulation to the primary somatosensory cortex. We used intraoperative monitoring of cortical SSEPs to determine whether the right anterior cerebral artery (RACA), the major feeding vessel of a large arteriovenous malformation (AVM), could be sacrificed without compromising sensorimotor function in the left lower extremity. The SSEPs recorded after test occlusion of the RACA showed preservation of the initial cortical positivity, and the RACA was divided. The AVM was excised completely, and the patient suffered no neurological deficit.
皮质体感诱发电位（SSEPs）反映了从刺激部位到初级体感皮层的体感通路的功能完整性。我们采用术中皮质SSEPs监测，以确定大型动静脉畸形（AVM）的主要供血血管——右侧大脑前动脉（RACA），在不损害左下肢感觉运动功能的情况下是否可以被牺牲。RACA试验性闭塞后记录的SSEPs显示初始皮质正波得以保留，随后RACA被切断。AVM被完全切除，患者未出现神经功能缺损。
