BACKGROUND: CT angiography (CTA) is increasingly used for the detection, characterization, and follow-up of @entity438 . A lower threshold to request a CT angiogram may render a @entity1 population that differs from previous studies primarily evaluated with conventional angiography. Our objective was to broaden our knowledge of the factors associated with @entity1756 and @entity1 mortality in this population. METHODS: All CTA studies performed over a 10-year period at a large neurovascular referral center were reviewed for the presence of an @entity438 . @entity1 demographics, mortality, CTA indication, @entity439 location, size, and @entity397 status were recorded. RESULTS: 2927 @entity1 with @entity439 were identified among 29   003 CTAs. 17% of the @entity439 were @entity397 at the time of imaging, 24% of @entity439 were incidentally identified, and @entity439 were identified in 34% of @entity1 . @entity439 most commonly arose from the supraclinoid internal carotid artery (22%), the middle cerebral artery (18%), and the anterior communicating artery (13%). Male sex, age <50   years, @entity439 >6   mm, and @entity439 arising from the anterior communicating artery, posterior communicating artery, or the posterior circulation were independent predictors of @entity1756 . Independent mortality predictors included male sex, posterior circulation @entity439 , @entity548 , and intraparenchymal @entity548 . CONCLUSIONS: These results indicate that @entity439 detected on CTA that arise from the anterior communicating artery, posterior communicating artery, or the posterior circulation, measure >6   mm in size, occur in @entity1 , and in @entity1 aged <50   years are associated with @entity397 .
