To clip or not to clip

The options for my aneurysm were clipping, coiling or nothing (monitoring with repeat MRI's every few months or so). Because of my age (42), the surgeon said that clipping is best as it is much more stable long term than coiling. He also said that if anything goes wrong in surgery at least they will have good access to be able to fix it before it causes too much brain damage, whereas with coiling this is not the case.

I do have confidence in my surgeon if I decide to go through with it, I am just having a lot of trouble making that decision. For all I know, my aneurysm may never rupture and I may not even need surgery. To anyone out there in a similar situation, what was it that made you go ahead with surgery on your unruptured aneurysm, rather than wait and see?

PS Robyn, I'm glad you were told yours would eventually rupture, that would certainly make my choice easier if I knew that but my doctors say they can't tell if it will ever rupture or not. It sounds as if I am a bit like you in the control freak status and I think this is what is bothering me so much. I feel like I should have the surgery to alleviate the massive stress and anxiety that goes along with having no control over this, but are psychological reasons an appropriate way to do decide to go ahead and have such major surgery?
