Understood. Mine was ascending aortic as well. As for flying, here's what I can say: If it's domestic it's probably fine. Wear compression socks, keep your blood pressure (BP) down. Check your bags and travel with a friend who's aware of your problem and can help if necessary. Wear a medical ID on your wrist. I dissected 24 hours after a flight from MSP to SAN (1,600 miles). Travel is stressful. We were also out tromping around sightseeing in the 113F Anza Borrego desert the day before the dissection. I genuinely did not know that HEAT spikes your BP. The day I dissected, I had been on my feet lecturing to a group of 55 lawyers for 13 straight hours. That was stupid. None of these things helped. Collectively they all added up to what was ultimately a a savage and life threatening complete dissection. So, do you fly? Sure, as long as you're cleared by your doctor, have a medical ID bracelet on describing your condition, and you TAKE IT EASY at all levels. Here's a picture of me the day before I dissected in 2015, then the following day after 13 hours of emergency open heart surgery. I'm on the left and I look really hot (and not the good hot). 113F in the California desert seemed like a lot of fun until it wasn't. All that said, I am here. I am alive. I have tears in my ears as I write to you. I am thankfully every single day for the life I got back from UCSD La Jolla. Thank you! You're going to be fine, but be smart and not dumb like me. Peace.
