ABSTRACT
The indicators of poor outcome in giant intracranial aneurysms have been the subject
of several studies in the literature. We conducted a retrospective analysis to evaluate
the predictors of poor outcome in giant intracranial aneurysms. We studied consecutive
cases with aneurysms admitted over a 9-year period in our institution. All the aneurysms
were treated with clipping. Patient demographics, clinical profile, and aneurysm characteristics
were evaluated in a multivariate analysis as probable indicators of Glasgow Outcome
Scale (GOS) score. The outcome of the aneurysms (GOS score) was compared with the
remaining non-giant aneurysms. A total of 41 giant and 348 non-giant aneurysms were
identified in our series. In the multivariate analysis, the indicators of poor outcome
were identified as poor clinical grade (p < 0.0004), intraoperative rupture (p < 0.007), and posterior circulation of the aneurysms (p < 0.01). Non-giant aneurysms had a better outcome compared with the giant aneurysms
(p < 0.01). Giant aneurysms impose a relatively higher risk of morbidity and mortality
to the patients. The predictors of the postsurgical outcome of the giant aneurysms
include the clinical condition of the patient, location of the aneurysm, and intraoperative
rupture.
