CFD Modelling of Abdominal Aortic Aneurysm on Hemodynamic Loads Using a Realistic Geometry with CT
Figure 1
(a) Main geometrical parameters: aneurysm length, maximum diameter of the aneurysm beginning of the AAA sac, ending of the AAA sac, nondeformed abdominal aorta diameter, is the absolute length of the tortuous vessel, and is the imaginary straight line. (b) Schematic visualization of a cross-sectional AAA section, where and are defined as the radii measured at the midsection of the AAA sac from the longitudinal -axis to the posterior and anterior walls.
