Method for modelling an endoprothesis implanted in a portion of a patient aorta

A computer-implemented method for simulating an interaction between an endoprosthesis dedicated to be implanted in a portion of a patient aorta and said portion of said patient aorta, so as to determine areas with risk of surgical complications, said method comprising:

• receiving 3D images of said portion of the patient aorta,
• reconstructing a deformable tridimensional digital model of said portion of the patient aorta based on said 3D images, the reconstructed deformable tridimensional digital model being referred to as aorta model,
• positioning a tridimensional digital model of said endoprosthesis at a planned location in said aorta model, said tridimensional model of said endoprosthesis and said aorta model forming together an implantation model,
• simulating said interaction based on a computation using said implantation model,
• determining, in the implantation model, based on results of said simulated interaction, at least one risk index of surgical complications for predefined areas,
• providing as output said at least one risk index of surgical complications for predefined areas.
