Most aneurysms involved the internal carotid artery (77.9%). The size of the aneurysm was 10\u201325\u2009mm in 81 (85.3%) and &gt;\u200925\u2009mm in 14 (14.7%). The procedure was successful in all patients (100%). At discharge, the mRS was 0 in 72 (78.3%) patients, 1 in 15 (16.3%), 2 in three (3.3%), 3 in one (1.1%), and 6 in one (1.1%). Four patients (4.3%) who had undergone PED (Pipeline embolization device) implantation experienced post\u2010procedural complications. Follow\u2010up was performed in 77 (83.7%) patients 6\u201365 (median 39) months after embolization, and 55 (71.4%) patients with 56 aneurysms experienced imaging follow\u2010up. At the last angiographic follow\u2010up 6\u201362\u2009months (median 37) after the procedure, four (7.1% or 4\/56) patients had instent stenosis, and total aneurysm occlusion with OKM (O'Kelly\u2010Marotta) grade D was in 45 aneurysms (80.4%). Flow diverter combined with coiling is a single independent factor affecting complete aneurysm occlusion (OR\u2009=\u20098.98, 95% CI 1.87\u201343.22, <jats:italic>p<\/jats:italic>\u2009=\u20090.006). In subanalysis, the treatment modality was significantly (<jats:italic>p<\/jats:italic>\u2009=\u20090.04) different in the large versus giant aneurysms, with diversion plus coiling being performed in all 14 giant aneurysms but only in 43 (53.1%) large ones.
