Ascending ao is a bit large but not a surgical indication per some searching. Id expect more testing, likely echo in the future to keep an eye on it. Mild effusion likely wont need intervention at this time.
A descending thoracic aorta diameter of 3,5 is within the normal range.
A descending thoracic aorta diameter of 2.9 is also within the normal range.
I do not expect that you need surgery in the future for your aorta.
