Purpose: The aim of this study was to evaluate the feasibility of endovascular treatment (EVT) for unruptured small wide-necked ophthalmic segment aneurysms (OSAs) of the internal carotid artery (ICA). Materials and Methods: Between January 2010 and May 2013, 17 patients with 19 unruptured small wide-necked OSAs received EVT. Occlusion rates were classified as total/near-total (95-100%), subtotal (80-95%) and partial (<80%) occlusions. This was determined by immediate and follow-up angiography. Follow-up outcome was assessed by using modified ranking scale (mRS). Results: EVT was successfully performed in all the patients: Coiling only in 2 (10.5%) and stent-assisted coiling in 17 (89.5%) of the aneurysms. The immediate total/near-total occlusion was seen in 1 (5.3%), sub-total occlusion in 8 (42.1%) and partial occlusion in 10 (52.6%). Follow-up angiography performed at 9.4 (±4.7) months revealed total/near-total occlusion in 13 (68.4%), subtotal occlusion in 5 (26.3%) and partial occlusion in 1 (5.3%). At the end of the follow-up period of 17.4 (±6.9) months, no aneurysm rupture was found and 16 (94.1%) of the patients had mRS scores of: Grade 0 in (5.9%) an mRS 1 in the remaining. Conclusions: EVT may be feasible and effective treatment option for unruptured small wide-necked ophthalmic aneurysms of the ICA.
