Dissection is the most common aortic catastrophe with an incidence of 5-30 cases/1,000,000/yr (Bickerstaff et al,1982).This injury is initiated by a sudden tear in the aortic intima and results in a rapid surge of blood into the aortic intramural space.The blood surge splits the media longitudinally and circumferentially, usually in an antegrade direction,resulting in two distinct channels for blood flow; the true and false lumens.Outcomes of this aortic emergency may include true lumen compression, malperfusion of the aorta and/or branch vessels, and aortic rupture.A type B dissection involves only the aorta distal to the left subclavian artcry.
