Occlusion rate of cerebral arteriovenous malformations (AVMs) by Gamma Knife Surgery (GKS) is very variaty depending on the study, may be due to the influence of the structural vascular elements of AVMs, its location, hemorrhage manifestation and follow-up time post-GKS. From 2010 to 2014, the authors had 48 patients who were treated with GKS alone, these patients were diagnosed before and after GKS by images (MSCT and/or MRI and/or angiography). The analyzed factors included: location of nidus (deeply or superficial area), the maximum size of nidus ( 20 mm and or 24 months). Ratio of occlusion of volume nidus were calculated. Univariate and multivariate analysis to find the elements related with occlusion AVMs. Rate occlusion or = 75 percent of the volume occupied by 55.3 percent (26/47), none of AVMs had done complete occlusion. Results of the study showed that favorable factors for high occlusion were: follow-up time postradiation surgery, small nidus and low Spetzler Martin before treatment (p 0.05).
