Total thoracic-abdominal aortic aneurysm is a rare disease in cardiovascular surgery, with high surgical risk and high mortality. Surgery is considered the most effective treatment for total aortic aneurysms. Recently, our group admitted a 60-year-old female patient with asymptomatic full thoracic-abdominal aortic aneurysm, and successfully performed staged surgery, namely Bentall + Sun’s operation in the first stage and thoraco-abdominal aortic replacement in the second stage. The results of the operation were satisfactory.
