I am not a neuro nurse so cannot specifically answer your question. However, my mom had an cerebral aneurysm clipped (clamped) in 2009, behind her right eye. She came through ok. It was very scary...not knowing if she would come out of surgery the same way she went it. Some pain on that side but the neurologist said that's normal.
We decided not to take our chances with it because it was pretty big, and I wouldn't want it to just break, say if she was driving or something like that.
