Introduction The study includes a series of 39 patients with AVM of the brain that are not subjected to any method of treatment, except for the symptomatic treatment who were hospitalized and diagnosed AVM at the Institute of Neurosurgery, Clinical Center, in the period 2005 to 2011.

Results The structure of the patients was measured by gender are male. Average age of the respondents was 27.4 ± 7.6 years. With the average length of the follow-up of 4.8 years, new hemorrhage occurred in 24 patients (58 episodes). Predictor (p < 0.01), factors for bleeding include: arterial supply from the VB and ACA basin and multiple arterial supply.

Conclusion The analysis of our series may be proposed for following model of the natural course of AVM: After initial hemorrhage, there is annual risk of rehemorrhage of 3.33%. Bleeding events were significantly more common in medium-sized AVM (2.5–5 cm), localized in elocvent area of the brain with combined type of venous drainage, arterial supply from the vertebrobasilar artery, anterior cerebral artery basin, or combined arterial supply.
