The authors present a monocentric retrospective study of a group of 27 patients operated for non-ruptured brain arteriovenous malformation (AVM) during years 1999–2017. The aim was to compare our results with the results of larger international studies and to draw appropriate conclusions. All patients underwent radical resection of the AVM and their clinical status was evaluated using the modified Rankin scale before and after the surgery with an average 6-year follow-up. The group was represented by the AVM´s Spetzler-Martin Scale I–IV. After resection, six patients improved, one deteriorated, and the others remained in the same condition as before surgery. Our morbidity was 3.7 % and mortality was 0 %. After 16 years of follow-up, no recurrence or residual malformation were detected in any patient. Compared to foreign studies, our results for all types of AVM´s are comparable and, therefore, for the unruptured the AVM´s Spetzler-Martin I–II microsurgical approach, for the unruptured AVM´s Spetzler-Martin III microsurgical approach with possible complementary alternatives of embolization or radiotherapy and for the AVM´s Spetzler-Martin IV–V rather observation can be recommended.

Key words:
unruptured brain arteriovenous malformations – microsurgery – treatment outcome – Spetzler-Martin Scale
