Management of Unruptured Intracranial Aneurysms

The amount of detail available in the medical record, and nature of neurological follow-up after intervention is not clear. It is recognized that major disabling adverse events would likely be defined via retrospective chart review, but less severe adverse events may be poorly characterized. Data from ISUIA suggest that cognitive outcomes may be an important contributor to the overall outcomes after treatment, but those data were not available in the present study.3 Additionally, assessments of neurological status other than modified Rankin Scale were understandably not available in this retrospective review. From the perspective of aneurysm elimination, the results achieved with initial coiling are less impressive with com- plete obliteration of the aneurysm accomplished in 72% of small aneurysms, 59% of medium sized aneurysms, 35% of
