I have never heard of an aneurysm going away without treatment. I am a survivor of two brain aneurysms. I was treated with a coiling 08/06 and clippings 05/07 and my advice to you is to keep your blood pressure as low as possible and definitely do not smoke. I hope everything works out for you. I know what your going through.
Hi - welcome to the forum. It can be incredibly challening when you have a child to think of as well. I pray you are guided to what is right for you and her.
I haven't heard of annies going away. I have heard of them not growing and remaining the same size. Some things to help this is to not smoke, keep blood pressure down and eat healthy. Well even healthy people can have them ( The guy who won this years Tour de France had a ruptured annie and is doing fantastic ).
One other thing is to reduce your stress ;-) Not always easy but necessary.
How big is your annie? Are your doctors watching it right now?
