Computational Modeling of Abdominal Aortic Aneurysms

Abdominal aortic aneurysm (AAA) is a dilation of the aorta beyond 50% of the normal vessel diameter that is frequently observed in the aging population and it affects 6–9% of the people in the industrialized world. This study reviews some of the computational methods in the diagnosis and treatment of AAA. We presented a literature survey on AAA biomechanics reported by several aspects from experimental tissue test including our own experimental testing, constitutive model, and intraluminal thrombus (ILT). Our finite element model with fluid–structure interaction approach with the computational study of the aneurismatic pathology is presented. Computational methods have made possible the patient‐specific analyses, a feature essential for understanding the progression of AAA in a particular patient. Finally, future clinical decision support system is suggested by using data mining approach.
