Understanding abdominal aortic biomechanics: in vivo stress and load-bearing prediction

Abstract

The abdominal aorta plays a critical role in blood circulation, and understanding its mechanical behavior is essential for the prevention and treatment of vascular diseases, such as aneurysms and atherosclerosis. This study aims to evaluate the stress state and load-bearing fraction in the abdominal aorta using an in vivo parameter identification method. This method combines medical imaging data with mechanical modeling to accurately estimate the mechanical properties of the aortic wall. The study employs finite element analysis (FEA) to model the abdominal aorta's stress distribution and load-bearing capacity under physiological conditions. Results indicate that this method provides a reliable estimate of the aorta's mechanical behavior and offers potential clinical applications in the personalized assessment of vascular health.
