You're going to be fine. Generally surgery is not implicated until you reached 5.0 cm. You are going to want to keep your weight down your blood pressure down and no smoking or heavy drinking. You'll see your doctor next week and everything will be just fine. I had a complete aortic dissection in 2015 that I survived. I get annual CT scans with contrast of my aorta and other vasculature and mine is typically 4.1 to 4.2 cm after open heart surgery to repair it. I am still here after 10 years and thankful for every day. You'll be just fine because you know you have an issue and you can deal with it in an orderly fashion, as opposed to an emergent fashion like I had to. Just meet with your medical team and follow their careful advice. They're watching out for you and you're going to be OK. Peace and have a relaxing holiday.
