title: Endovascular treatment for unruptured intracranial aneurysms in elderly patients: single-center report.
abstract: OBJECTIVE
  The optimal management of patients with unruptured intracranial aneurysms remains controversial in elderly populations. The aim of this study was to evaluate technical results and clinical outcomes in a single center of consecutive elderly patients with unruptured intracranial aneurysms treated with endovascular embolization.
  
  
  METHODS
  Between May 2003 and February 2010, 96 patients older than 70 years (men, 16 patients; women, 80 patients; mean age, 73 years) with 122 saccular unruptured intracranial aneurysms were treated in our hospital with an endovascular approach. The endovascular procedures and technique, angiographic follow-up, and complications were evaluated.
  
  
  RESULTS
  Successful embolizations without complications were completed in 95.9%. Five patients had procedure-related events, including thromboembolism in 1 patient, aneurysm perforation during the procedure in 1, and 3 postoperative transient minor symptoms (headache, otalgia, and trigeminal pain) in 3. The degree of occlusion of the treated aneurysm was complete in 46.7%; there was a small neck remnant in 40.9% and residual filling in 12.2%. Imaging (MR angiography) follow-up was performed in 68.7% of the patients. The mean follow-up duration was 19.4 months (range, 5-57 months). Fifty-five patients (93.9%) showed no interval change of the residual neck. Four (6%) demonstrated recanalizations, all of which were successfully recoiled.
  
  
  CONCLUSIONS
  Endovascular treatment of unruptured intracranial aneurysms in patients older than 70 years of age appears to be safe. Favorable outcomes with low morbidities may replace surgery or conservative treatment as an active management alternative.
