abstract

  • Evaluating the risk of endograft migration is important for longterm durability of endovascular aneurysm repair (EVAR) technique. In this paper we apply a step-wise coupled finite element approach to evaluate the risk of endograft migration in representative aorta models subjected to in-vivo hemodynamic displacement forces. Device stability is observed to be a strong function of aortic geometry (tortuosity, proximal fixation) with increased tortuosity or lower proximal fixation leading to greater risk of device migration.
