↵a Statistically significant values. Factors tested as predictors of complications: age, sex, embolization, initial aneurysm occlusion, and date of treatment. Factors tested as predictors of recurrence, retreatment, and new or recurrent hemorrhage: age, sex, aneurysm size, location, ruptured aneurysm status, Hunt and Hess grades, type of embolization, initial aneurysm occlusion, date of treatment, procedural complications, GOS at discharge, and follow-up time. Factors tested as predictors of clinical outcome: age, sex, aneurysm size, location, ruptured aneurysm status, Hunt and Hess grades, type of embolization, initial aneurysm occlusion, date of treatment, procedural complications, GOS at discharge, follow-up time, recurrence, retreatment, and new or recurrent hemorrhage.
