Abstract Objective: The purpose of this study was to evaluate the results of surgical treatment in 100 cases of
intracranial aneurysms performed by the author.
Materials and Methods: The study was designed as a retrospective study involving 100 patients (57
females and 43 males) who underwent surgery for ruptured intracranial aneurysm between 1991-2002. Patients?
age, gender, location of aneurysm, and subarachnoid hemorrhage (SAH) clinical grading (Hunt and Hess
grading) were studied and correlated with the outcome following surgery.
Results: Thirty six patients (36%) had aneurysm of the posterior communicating artery (PcoA), 33
patients (33%) had aneurysm of the anterior communicating artery (AcoA) and 17 patients (17%) had aneurysm
of the middle cerebral artery (MCA). The outcome as evaluated by the Glasgow outcome scale was good
recovery in 60 patients (60%), moderate disability in 11 patients (11%), severe disability in 7 patients (7%) and
death in 22 patients (22%). Good recovery and moderate disability patients (71 patients or 71%) were classified
under the favorable outcome group whereas patients with severe disability and death (29 patients or 29%) were
classified under the unfavorable outcome group. According to Hunt and Hess SAH grading, the patients with
SAH grade I-III had favorable outcome in 60 patients (92%) and unfavorable outcome in 5 patients (8%) whereas
the patients with SAH grade IV-V had favorable outcome in 11 patients (31%) and unfavorable outcome in 24
patients (69%).
Conclusion: This study of 100 cases revealed 71 cases with favorable outcome, 7 cases with severe
disability and 22 death cases. Patients with SAH grade I-III had favorable outcome in 60 cases (92%) and death
in 5 cases (8%). Factors that affected the outcome were SAH clinical grading and the age of patients.
