I had a Type A-1 complete dissection in 2015 repaired by emergency surgery at UCSD. The difficulty swallowing and hoarseness likely come from the fact that your aorta is enlarged and pressing up against your esophagus. I had serious difficulty swallowing before (and still after) my dissection. Think of it like this overly simplistic analogy: an aortic aneurysm is like a water balloon inside of your chest, slowly stretching, and getting bigger over time. If it breaks, you're in big trouble. In 2021, I saw 8K High-Def CT Scan Images in 3D at the University of Minnesota during my semi-annual scans after surgery. The U of M imaging center at Fulton Street in Minneapolis is FANTASTIC for follow up annual surveillance scans. I literally could see my aorta pressed against my esophagus. Following two open heart surgeries (one to repair and one to close me up and check for leaks three days later) I had to have throat surgery to repair my vocal cords. So, I think that it's smart to get a second opinions--especially if you're having trouble swallowing. Unless this has happened to you, and you happen to be a thoracic surgeon, it's hard for doctors to sometimes grasp the little things that precede a dissection. There were huge red flags in my life that I did not see until after it dissection (trouble swallowing was a big one). I would strongly recommend a second opinion at Mayo, Cleveland Clinic, and my favorite UCSD-San Diego. Find a thoracic surgeon that has done lots of these and has been around for 30 years. You're right to be concerned and right to get a second. You're going to be fine.
