Aortic dissection is a medical emergency situation requiring quick and proper treatments, otherwise patient can suddenly lead to death as a result of rupture of the aorta. The rupture can be triggered by many factors such as blood pressure, velocity, viscosity etc. and it is critical for patients to manage the internal and external factors acting on the blood vessels before the rupture begins. To control the factor like blood pressure, we need to set a threshold value for the safe zone for each patient to provide proper treatment guidelines. This important threshold can be obtained from the analysis of blood flow in the 3D model of aortic dissection. In this study, we analyzed CT images obtained from three patients who had three different type of the aortic dissection, respectively. The fluid flow simulations were done by using COMSOL Multiphysics. The results from the computational simulation are able to explain the blood flow characteristics and are well accordance with the expectation from the patient’s condition and types of aortic dissection.
