Hi!! So sorry to hear you had to go through all of this. I had aberrant right subclavian. I had surgery Nov 2019 at Mayo Rochester with Dr. Bower. My case is unique in the sense- i had no symptoms whatsoever. I also had no dilatation of the aberrant artery. I did have a large left subclavian aneurysm and descending aortic aneurysm. My cardiologist here in Florida sent me to Mayo right away, and with Dr. Bower and Dr. Pochettino help I had a 2 day surgery-- day one Dr. Bower relocated my aberrant artery to my carotid( only because it was in the way for my aortic grafts I needed) and day 2 Dr. Pochettino replaced a large portion of my aorta and left subclavian. I highly recommend if you are needing a second opinion trying Mayo. Not many doctors know how to approach an aberrant artery. If your not having symptoms it may just require some routine imaging--mine was a Ct scan. I was told the main issue with this is the development of Kommeralls diverticulum-- which is basically an aneurysm on the right subclavian-which doesn't happen all the time. Dr. Bower told me that if I did not need the aberrant artery moved because it was in the way of the graft for my other issues- he doubts my aberrant artery would have ever caused me any issues. I highly recommend before you panic to see a dr who is well experienced with this issue like Dr. Bower. It really did help me. Best wishes.
