The aim of this work is the development of a Finite Element Analysis (FEA) to a patient-specific case, to evaluate an optimal configuration in a chimney graft technique (smallest possible gutter). To achieve that, an abdominal aorta segment and two models with different diameters (9 and 28 mm) of stent grafts were designed with Rhinoceros and tested with Abaqus software. This Finite Element Analysis (FEA) allowed to capture the deformation of sandwiched stent grafts under radial compressive forces due to the oversizing inside abdominal aorta. The formed gutter areas for the CG configurations were measured.

Abstract
The aim of this work is the development of a Finite Element Analysis (FEA) to a patient-specific case, to evaluate an optimal configuration in a chimney graft technique (smallest possible gutter). To achieve that, an abdominal aorta segment and two models with different diameters (9 and 28 mm) of stent grafts were designed with Rhinoceros and tested with Abaqus software. This Finite Element Analysis (FEA) allowed to capture the deformation of sandwiched stent grafts under radial compressive forces due to the oversizing inside abdominal aorta. The formed gutter areas for the CG configurations were measured.È consentito all'utente scaricare e condividere i documenti disponibili a testo pieno in UNITESI UNIPV nel rispetto della licenza Creative Commons del tipo CC BY NC ND.
