Abstract

BACKGROUND
The prevalence of intracranial aneurysms in the elderly is increasing. However, most treatment strategies for the elderly is controversial and related research in the elderly has been insufficient.
METHODS
Eighty-four patients > 65 years of age with intracranial aneurysms who received definitive treatment at our hospital between March 2007 and June 2010 were subjected to this study. Thirty-seven patients who had undergone endovascular treatment (EVT) were categorized into group I, while 47 patients who had undergone microsurgical treatment (MST) were categorized into group II.
RESULTS
When the Glasgow Outcome Scale (GOS) score, which was independent to rupture, was evaluated at the time of discharge there was a trend of acquiring much better GOS scores (GOS> or =4) when the Hunt-Hess grade (HHG) is good (HHG< or =2) and the size of the aneurysm is small (<10 mm; p=0.001 [HHG] and p=0.000 [aneurysm size]). In the two groups in which EVT and MST were performed, the average values of the GOS scores by Student's t-test displayed a significant difference (4.54 [EVT] and 4.13 [MST], respectively, p=0.046). However, univariate and multivariate analyses were not statistically significant.
CONCLUSION
If the clinical results are similar in the EVT and MST for intracranial aneurysms, then EVT is less invasive with less post-procedural complications would be considered with priority in elderly patients.
