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.
