Morphological characteristics of BAVMs and aneurysms, arterial supply and venous drainage of the BAVM, and the presence of intracranial hemorrhage (ICH) were retrospectively evaluated. A\u00a0comparative analysis of the characteristics of the BAVMs was performed between the group with BAVMs alone and the group with BAVMs with aneurysms. The assessment of BAVMs was based on the Spetzler-Martin scale, while the classification of IAs was based on BAVM vascularity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>BAVMs associated with IAs (n = 28), compared to BAVMs alone (n = 61), showed no significant differences\nin BAVM nidus size (27.32 vs. 26.10 mm) or number of arterial supply sources (64.29% vs. 54.10% for a\u00a0single source). BAVM patients with aneurysms experienced significantly more ICH (57.14% vs. 34.43%; p &lt; 0.05). A\u00a0total of 42 IAs with an average size of 4.92 mm were described, of which 42.86% were multiple. Flow-related aneurysms were the most common type (n = 26, 61.90%). The type of aneurysm had no statistically significant effect on the incidence of bleeding.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The coexistence of BAVMs and IAs was observed in 31.46% of patients in this study.
