Chapter 5 - Aortic dissection: Numerical modeling and virtual surgery

Abstract

Aorta, as the main and the largest blood vessel in the human body, is constantly exposed to high pulse pressure and shear forces. Aortic dissection is a very serious condition and medical emergency, which leads to tearing and delamination of the inner layer of the aortic wall, while the outer layer remains intact. Numerical simulations of the dynamic behavior of fluid/blood in the aorta dissection can be of great help to doctors, because these simulations can provide insights into further development of the disease. The main objective of the chapter is to determine pressures, wall shear stress, and velocity in the true and false lumen by applying numerical simulations, which gives a clear picture of the relationship among them.
