BACKGROUND: Clipping a paraclinoid @entity439 is difficult if the @entity1 has a visual disturbance. Visual function sometimes deteriorates postoperatively for @entity1 with a large @entity439 . In this study, we report the long-term follow-up of @entity1 with @entity227 attributed to @entity2850 when paraclinoid @entity439 are surgically treated. METHODS: Seventeen @entity1 with @entity1781 induced by compression of @entity439 were treated. All of the @entity439 were large, including 6 @entity439 . The @entity439 displayed partial @entity715 or @entity730 of the aneurysmal wall in 6 cases. RESULTS: Direct surgery such as neck clipping or wrapping of the @entity439 was performed in 9 @entity439 and indirect procedures in 8 others (ICA occlusion, 1; ICA occlusion + bypass, 7). Of 17 @entity1 , 11 (65%) showed @entity227 or visual field. Of 6 @entity1 , whose vision had not recovered well, 5 underwent direct surgery. Moreover, these 5 @entity1 had an intra-aneurysmal @entity715 or @entity730 of the aneurysmal wall. Nevertheless, 1 @entity1 whose @entity439 with partial @entity715 was treated via indirect procedure had good recovery of vision. CONCLUSIONS: Direct clipping is the treatment of choice for @entity1 with a mass effect on the optic nerve due to paraclinoid @entity439 . However, it is difficult to achieve sufficient decompression of the optic nerve when the @entity439 is accompanied by partial @entity715 or @entity730 of the aneurysmal wall. In those cases, an indirect procedure seems to be a relatively safe, effective treatment.
