ABSTRACT

Aortic dissection is the commonest aortic emergency affecting 10 to 20 people per million

population (1). The mortality associated with dissection is high if no treatment is given, with

mortality ranging from 36% to 72% (2). Mortality from dissection is approximately 1% per hour

for the first 48 hours with a higher mortality when the ascending aorta is involved (2). Death

results from rupture into the pericardial cavity causing tamponade, or from rupture into the

mediastinum, the pleura or the abdomen. Serious complications arise from ischemia of the

branch vessels resulting inmyocardial infarction, stroke, limb ischemia, paraplegia, visceral and

renal ischemia.
