Aortic dissection is an acute condition occurring more frequently than ruptured abdominal aortic aneurysms, with a mortality rate increase of 1% per hour if left untreated [1]. Dissection occurs following creation of an entrance tear, through which blood can force its way into the wall, forming a pocket that propagates longitudinally. The membrane of the dissection flap separates the true lumen (through which the organs are supplied with blood), from a false lumen (the pocket created by the dissection). The total obstruction of the true lumen by the motion of the vessel flap, or organ starvation due to branch vessel compression by the false lumen, can be fatal. Figure 1 shows an idealised representation of an aortic dissection model.
