Abstract

The abdominal aortic aneurysm is tenth most common cause of death in Western countries. Since maximal transverse diameter as indication for surgical interventions is often criticized, biomechanics of the aneurysm has been studied to develop new criteria for a treatment. The Finite Element Method is being utilized to predict vessel stability. Computer simulations are proven to have high accuracy of rupture risk assessment, although the impact of all incorporated factors is still not fully known. The objective of this paper is to review the most commonly used biomechanical components of computer analysis, including geometry of the vessel, mechanical properties of the wall, thrombus and calcification, their impact on rupture risk, and methods of modelling blood pressure. Comprehension and precise assessment of biomechanics of aneurysm in terms of Finite Element Analysis have high potential in clinical management of abdominal aortic aneurysm.
