Prognosis after non-surgical therapy for acute type A aortic dissection.

Mortality from AAAD is 51.4%, including inappropriate candidates for surgery. When patients were evaluated as suitable candidates for surgical intervention but subsequently refused the surgical procedure, in-hospital mortality was 37%. Long-term survival of hospital survivor was acceptable. These data can be a benchmark for patient and patient's family to select medical therapy for AAAD in consideration with the patient's will.
