Alloyjohn. Shoot me an e-mail with any questions you might have about the surgery, I will be happy to try and provide answeres.
My surgery was a "Must," my aneurysm was about the size of a tennis ball, found by accident while looking at another problem. The surgery was not too bad, the recovery was fairly fast, and today I feel like a million dollars.
As I said, I spent eight days in the hospital, but yours may be less. The recovery time depends on you, for me it was not too bad. In two months I was back to doing almost everything I wanted except heavy lifting. The pain was bad for the first few days, but once I left the hospital I never took another pain pill. Being split down the middle has an impact on every mussel in the body, whatever you move seems to hurt for the first few days.
If you have any specific questions, leave me a personal message with the questions and I will try to answer them for you.
Bottom line, this is a very serious condition. keep in mind, if that thing pops, you will be dead in less than 5 minutes, and it makes no difference if you are in the emergency room when it happens, there is nothing no one can do to save you. Get it fixed, and your life should be back to (fairly) normal in a short period.
