If a patient has an aortic aneurysm dissection in the chest, does a thoracic surgeon or vascular surgeon repair it?

A thoracic surgeon is a heart and lung specialist who does surgery on the chest cavity, while a vascular surgeon is a doctor who specializes in surgery on blood vessels. So, if someone has an aortic aneurysm dissection in the chest, a thoracic surgeon would be the best doctor to repair it.
