Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEM) of a Customized Stent-Graft for Endovascular (EVAR) Treatment of Abdominal Aortic Aneurism (AAA)

Background: The treatment of abdominal aortic aneurysm (AAA) is today commonly treated by inserting a stent-graft the endovascular route, without resorting to open surgery. However, some clinical cases do not allow this less invasive approach, meaning that cannot be inserted and surgery used. Methods: In study, we propose fluid–structure interaction (FSI) analysis an aneurysmatic aorta could with Endovascular Aneurysm Repair (EVAR). vessel reconstructed through segmentation from CT scans subsequently modeled on CAD software create surface thickness itself. Subsequently, proceeded carry out Computational Fluid Dynamics (CFD) FSI simulation. We computational study geometry faithful reality customized. Results: Hemodynamic variable results carried simulations indicate low velocity consequently very WSS areas located in aneurysmal site are no longer found when conventional or patient-specific grafts inserted. wall stress distribution FEM enabled identification area at risk failure, is, posterior part (∼107 Pa), while graft led uniform von Mises stresses (∼105 except for junctions where peak occurred. Conclusion: importance highlight benefits personalized stent/graft. As authors expected, shows numerous customized stent/graft terms blood flow trend compared traditional supporting tendency want shift target towards stents/grafts, also vascular sector.
