Abstract
The goal of cerebral arteriovenous malformation (AVM) treatment is to eliminate intracerebral hemorrhage risk and to preserve or maximize neurological functions of the patient. Interventional planning must determine the modality or combination of modalities with the greatest success rate according to patient characteristics, AVM architecture, and the capabilities of the treatment option to fulfill the goals of treatment. Although there is a lack of data from randomized trials to guide AVM management, microsurgery is a mainstay of therapy in patients receiving definitive intervention. In this paper, we review current guidelines for surgical planning, risk-benefit analysis, and prediction of outcome in AVM patients.
