Background: The multimodal intraoperative neurophysiological mapping (MIONM) have been represented a great enhancement to surgical brain arteriovenous malformation (AVM) treatment.
Purposes: This study aim to show up the importance of this tool to manage the nidus resection, to prevent and to reduce the morbidity and the mortality at brain eloquent regions.
Methods: About 19 patients were appraised after surgical resection of AVM lesions under surrounding keep track of neurophysiological mapping at Ophir Loyola’s Hospital, between 2012–2016.
Results: Male was the most common, at 20 to 40 years old of age, also most of AVM was scored II and III by Spetzler and score below and equal 6 scored by supplementary Lawton scale. About 57.7% presented hemorrhagic event, followed by headache and seizure as main clinical presentations. The angioarchitetural findings were reported by sulci-giral as the most prevalent (68.4%), 47.4% coursed without any post-operative deficit after the surgery, but also the cure rate achieved 100% of complete nidus resection.
Conclusions: Nevertheless, the study did not reveal statistical importance as a tool to ensure the secure AVM resection, the study imply with a small cluster of patients that the MIONM was important to reduce the morbidity and mortality after AVM microsurgery resection together high cure rate. So the author judge the importance of new studies with more patients under the same method to get a statistical power to show up the highlight point of view at prevention during the AVM surgery.
