Aortic Dissection
Prognosis for Aortic Dissection
About 20% of patients with aortic dissection die before reaching the hospital. Without treatment, mortality rate is is approximately 1 to 2% per hour after symptom onset. Without surgery, mortality is > 50% at 1 month ( Prognosis references ). Hospital mortality rate for treated patients is about 20% for type A dissection and 10% for type B dissection ( Prognosis references ). One of the largest international registry databases reported survival rates of >90 percent for type A dissections treated surgically at 1 and 3 years postdischarge. However, the 3-year survival rate of patients with type B dissection was 78 % for those treated with medical management alone. 1.Tsai TT, Nienaber CA, Eagle KA.
