A computational assessment of the hemodynamic effects of crossed and non-crossed bifurcated stent-graft devices for the treatment of abdominal aortic aneurysms.

•Eight SG devices for crossed/non-crossed configurations were assessed.•Detailed examinations of drag force magnitude/components were reported.•SGs improve the hemodynamics within the sac region when compared with the pre-operative case.•Dean's number can be used to assess the variation in the hemodynamic effects.•44% to 62% of the resultant drag force occurred along the proximal centerline.•All crossed SG devices, further, promoted the spiral flow effect along its distal legs.
