I have had a rare celiac artery aneurysm for 3 years since it was discovered accidentally while performing a CT scan for some issue not related to aneurysms.

It measured 3 cm 3 years ago and I don’t know what the size is now. My cardiovascular surgeon gets annoyed frequently and this was no acception. The reason I had to see him was because a hospital said I have to go to a trauma hospital for emergency surgery due to my celiac artery being discovered and it had a tear on it. It was torn. The trauma hospital team debated admitting me but because it wasn’t bleeding that day I could be discharged with instructions that I see my own cardiovascular surgeon in ASAP. My doctor did a sonogram that I felt was not really the right way to look for it.
In any event he said “I didn’t see it” and “see you next year “ I said “could it burst and he said that it could “but we have ways to handle that” when? Bursts are quick and can be fatal so time is of the essence. I feel like a walking time bomb fearing it could happen anytime with nobody around.
What should I do? This guy is a jerk and I feel like a second opinion is warranted.
