Major causes of perioperative mortality and morbidity MI Paraplegia Renal failure Tamponade Hemorrhage Sepsis

Prognosis

Medically treated type A dissectiono About 33% of patients die within the first 24 hours.o 50% die within 48 hours.o The 2-week mortality rate approaches 75%.

Medically treated patients (type B dissection)o In-hospital mortality rate: 1020%

Surgically treated patients (type A or complicated type B dissection)o In-hospital mortality rate: 1525%

Long-term prognosis for patients with treated dissections is generally good withcareful follow-up.o 10-year survival rate: ~60%

Factors associated with increased in-hospital mortality and poor outcomes[1]o Age > 70 yearso Shock on presentationo Branch vessel occlusion resulting in myocardial ischemia or visceral ischemia
