神经电生理监测颅内动脉瘤介入治疗

Objective To study the application of neuroelectrophysiological monitoring for interventional therapy of intracranial aneurysms. Methods 22 patients with intracranial aneurysm were received neuroelectrophysiological monitoring during interventional therapy. Somatosensory evoked potential(SSEP) 、brainstem auditory evoked potential (BAEP) and visual evoked potential(VEP) were monitored during operation according to the position of intracranial aneurysm. Results 20 patients recovered well after operation. Temporary and hemiplegia were observed in 1 patient respectively. SSEP changes were observed in 8 patients, BAEP change in 1, and VEP change in 1. Cerebral ischemia was detected in 8 patients by neuroelectrophysiological monitoring and patients were given adequate management immediately. The therapeutic schedule of 2 patients were changed during neuroelectrophysiological monitoring in order to decrease the risk. 1 patient was evaluated again during neuroelectrophysiological monitoring so that the original interventional therapy schedule was not given up. Conclusion Neuroelectrophysiological monitoring is significantly important during interventional therapy of intracranial aneurysm, which could reduce the risk of cerebral ischemia and enhance treatment security.
