Abstract: ObjectiveTo discuss the role of neuronavigaition technique in localizing and facilliating microsurgical resection of intracranial ateriovenous malformations (AVM) .Methods Forty-three cases with intracranial AVM treated microneurosurgically asisting by Stryker Leibinger neuronavigation system were retrospectively analyzed.Results After reaching neuronavigation calculated technical accuracy (less than 2 mm) and continual intraoperative navigating accuracy, all of the 43 AVM lesions were completely resected.In 41 patients, syptoms were significantly improved (95.4％) at discharge, new neurofuntion defection were found in 2 patients(4.6％) , no death occured.ConclusionNeuronavigation techniques helps the surgery in planning a precise surgical approach to the targeted AVM lesion and tracing the neurovascular structures ,improves the safety of the surgery and the functional outcome of the patients, contribute to lesion resection and reduce operative complications.
