Abstract:

This study is based on image-based CFD (Computational Fluid Dynamic) that will help in providing an enhanced understanding of the blood pressure impact on the wall of Abdominal Aneurysmal Aorta (AAA) for diabetic patients and its relationship with whole blood viscosity (WBV). This relation can provide the physician an indication about the consequences of diabetes disease on the AAA. Simulation technique was used as it is difficult to perform such studies in real patients where AAA problems have no symptoms. Thus, the arterial systems computational models are used to inspect the growth, rupture, and thrombosis of the aneurysm. Idealized 3D AAA models are created to analyse the aorta pressure in different areas. The CFD, is a software that has been used to determine the relationship between WBV and AAA wall pressure and then to compare the obtained values to blood viscosity (BV) for normal subject. The results were compared between the normal and diabetic models. The change in the pressure values is due to the change in the viscosity values. The values of the diabetic patient’s whole blood viscosity are higher compared to the normal viscosity, which in turn is recorded as increasing the pressure on AAA wall. The results show that the BV has a direct impact on the AAA wall pressure values. Therefore, the pressure on the AAA wall increases as BV value increases.
