Endovascular Treatment of Intracranial Ophthalmic Segment Aneurysms: A Series and Literature Review

Abstract

Aim: To present the outcomes and follow-up results of endovascular coil embolization in patients with ophthalmic segment aneurysms (OSAs).

Material and 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.

Conclusion: Endovascular treatment is a safe and effective treatment modality for intracranial OSAs.
