The study objective is to evaluate the results of endovascular treatment of patients with subarachnoid hemorrhage due to rupture of the vertebrobasilar artery aneurysm.Materials and methods. From 2011 to 2017, 26 patients underwent endovascular occlusion of the ruptured vertebrobasilar artery aneurysm in an acute period of hemorrhage in Surgut Clinical Hospital for Traumatology.Results. Endovascular interventions were performed in 1–14 days after the episode of the primary subarachnoid hemorrhage. Among the patients 53.8 % were in good condition at admission (Hunt–Hess grade I–II), 46.2 % had moderate and severe neurologic disability (Hunt–Hess grade III–IV). A good and satisfactory degree of aneurysm occlusion was achieved in 18 (69.3 %). Favorable outcome (modified Rankin Scale (mRS) 0–2) was achieved in 21 (80.7 %); 1 (3.7 %) had severe disability (mRS 4), 2 (7.8 %) – vegetative state (mRS 5). Lethal outcome (mRS 6) occurred in 2 (7.8 %). Unfavorable outcomes were caused by a severe vasospasm.Conclusions. Endovascular occlusion of vertebrobasilar artery aneurysms in the acute period of hemorrhage is an effective and safe method of treatment in patients with Hunt–Hess grade I–IV.
