The Impact of a realistic complete Stenting Procedure on the Migration Behaviour: a Numerical Analysis
Author(s): Altnji Sam*, Fayade J and Bou-Said B
The migration of the stent graft is one of the main complications of Endovascular aneurysm repair (EVAR). It is closely related to ineffective contact between the endograft ends and the wall of the blood vessel. In this study, we have developed a realistic stent-graft deployment simulation using the Finite Element Method of 3D nitinol stent in a patient-specific Thoracic Aortic Aneurysm (TAA). This work aims to investigate the impact of the realistic complete stenting procedure by a progressive expanding deployment of the stent graft on the migration behaviour. A comparison of results is investigated between the realistic and non-realistic deployment methods to predict the overall (stent–aorta) biomechanical behaviour. We have also investigated the effect of including the graft material on the mechanical behaviour of the (stent-graft) during the deployment and the contact stabil.. View more»
