Key result
Traditional mechanisms of blood cleavage and medial hemorrhage alone are insufficient to cause aortic dissection in some cases based on analysis of pressures and forces.

Challenges standard aortic dissection models; leaves open alternative initiation mechanisms for investigation.
There are two generally proposed causes of dissection of the aorta: (1) cleavage caused by blood entering the tear; and (2) haemorrhage that dissects the media and tear secondary to the cleavage. Using analysis of pressures and forces, this article shows that, on some occasions, these mechanisms alone cannot be responsible for causing aortic dissection
