Abstract
Aortic dissection is one of the acute aortic syndromes and a type of arterial dissection. The term Acute Aortic Syndrome (AAS) is used to describe a spectrum of life- threatening aortic emergencies of the thoracic aorta: classic Aortic Dissection (AD), Intramural Hematoma (IMH) and Penetrating Atherosclerotic Ulcer (PAU)1,2. Aortic dissection starts with a tear in the intima of the aortic lining. The tear allows a column of blood under pressure to enter the aortic wall, forming a haematoma. Hemorrhage in the media (at vasa vasorum) leads to either a tear in the weakened intima which breaks into the lumen or hemorrhage separates media from adventitia 1,2,3.The false lumen extends for a variable distance in either direction.
