Abstract
Objective
Symptomatic unruptured intracranial aneurysms (UIAs) have been actively treated due to a high risk of rupture. However, there is a higher tendency of treatment-related complications in elderly patients. Our study aimed to investigate the treatment outcome and complications of symptomatic UIAs in patients of age 70 and more.
Methods
Between May 1997 and July 2015, consecutive 19 symptomatic UIAs had been treated by either open surgery or endovascular surgery in 18 elderly patients (≥70). Clinical and radiologic data of these patients were retrospectively reviewed and their treatment results, complications, and functional outcomes were evaluated.
Results
Interval from symptom onset to treatment was mean 1.4 months. Of 18 patients, six cases (31.6%) were treated by open surgery and 13 cases (68.4%) were treated by endovascular surgery. Procedure-related complications occurred in three cases (15.8%) with three of unfavorable outcomes (16.7%). During the follow up (mean 37.3 months), there were 5 cases (27.8%) of complete recovery, 8 cases (44.4%) of partial recovery, and 5 cases (27.8%) of no response of initial presentations.
Conclusion
Treatment of symptomatic UIAs can be feasible in elderly patients (≥70). However, there was a high rate of procedure-related complications (15.8%) and unfavorable outcomes (16.7%). Therefore, precise evaluation and careful decision is mandatory before the treatment.
