    The study utilized hemodynamic simulations based on patient-specific AAA models to investigate energy loss associated with Type I endoleak after EVAR.

  • 2

    Computed tomography angiography was employed to reconstruct models for patients with and without Type I endoleak, facilitating endoleak component quantification.

  • 3

    Endoleaks were found to localize at stent-graft junctions, showing higher turbulence energy loss and mean flow energy loss compared to the no endoleak group.

  • 4

    Turbulence energy loss values were significantly elevated in the endoleak group across main and iliac branch stents following EVAR.

  • 5

    The study suggests that energy loss component quantification may offer a feasible method for evaluating Type I endoleak in patients post-EVAR.
