ABSTRACT
Introduction Acute aortic dissection is a life-threatening emergency with an overall in-hospital mortality of 27% reported by the International Registry of Acute Aortic Dissection (IRAD).1 If the condition is left untreated, 36-72% of patients die within 48 hours of diagnosis, and 62-91% die within one week.2 The incidence of acute dissection has been reported to be greater than that of ruptured abdominal aortic aneurysm.3
