Abstract：Objective To investigate the value of MRI and 3D-DSA images fusion combined with intraoperative neuro-electrophysiological technique to the surgery for intracranial arteriovenous malformation (AVM) associated with epilepsy. Methods MRI and 3D-DSA images fusion was performed in 1 patient with epilepsy induced by AVM, in whom, AVM and epileptogenic zone were resected by neuronavigator-assisted surgery under eletroophysiological monitoring. Results The lesion was exactly located by MRI and 3D-DSA images fusion. The main arteries supplying blood to AVM and veins dainaging from AVM were found by the real-time navigation and then were ligated and cut off. AVM was totally resected. The epileptogenic zone and the functional cortex were accurately located by intraoperative eletrophysiological technique. The epileptogenic zone were successfully resected without neurological functional deficits. Conclusions MRI and 3D- DSA images fusion technology, which can clearly show anatomical structure and vascularity on the same image, combined with electrophysiological technique, which can locate epileptogenic zone and functional areas, is of the great value to the surgery for the epilepsy secondary to the intracranial AVM.
