title: Endovascular Treatment of Intracranial Ophthalmic Segment Aneurysms: A Series and Literature Review.
abstract: OBJECTIVE
  To present the outcomes and follow-up results of endovascular coil embolization in patients with ophthalmic segment aneurysms (OSAs).
  
  
  METHODS
  The data of 42 patients with 44 OSAs (7 ruptured and 37 unruptured), who underwent treatment using endovascular techniques between January 2007 and November 2010, were retrospectively reviewed.
  
  
  RESULTS
  The angiographic occlusion of the aneurysms was complete for 37 aneurysms (84.1%), near complete for 4 aneurysms (9.1%) and incomplete occlusion for 3 aneurysms (6.8%). There were 2 (4.5%) symptomatic procedure-related complications (ischemic events). One patient died of massive cerebral infarction caused by a large dissecting OSA. A favorable outcome was achieved in 97.6 % (41 of 42) of the patients at the time of follow-up. No sign of bleeding or re-bleeding was observed in any patient during the follow-up period (1 to 44 months, mean 14.2 months). Minor aneurysm recanalization occurred in 2 (4.5%) cases. The OSA-associated visual disorders completely recovered in 9 (64.3%) patients.
  
  
  CONCLUSIONS
  Endovascular treatment is a safe and effective treatment modality for intracranial OSAs.
