What is the prognosis after aortic aneurysm repair for ages under 50 yrsold?

Excellent: Any part of the aorta can become aneurysmal so some of the prognosis depends on where chest- ascending or descending abdominal it also depends on endovascular or open surgical repair/ or replacement open repair has a long track record of success. The endo technique is in evolution and adds some new complications and a short track record.

Great, but....: The big question is why does such a young person have an aneurysm in the first place? That will likely determine how well you do in the long term.
