I've also tried to find some information on this. A set of guidelines from Mayo would be wonderful.

That said, I'm not sure anyone knows the answer. There are so many variables. FWIW, I've seen some YouTube videos and papers from Dr. Siddharth Prakash who seems to be studying this very concern. He seems to focus a little more on people who have had a dissection. I'm not sure how the risk of that group would compare to people whose aneurysms have never dissected.

Here's one video: https://www.youtube.com/watch?v=yhMEZ0glPqc&t=23s
