Fig 1 Sequential completion angiograms: A, Initial retrograde angiogram shows stenosis at the graft limb origin. B, Retrograde angiogram after balloon angioplasty shows lesion resolution (first operation). C, Antegrade angiogram (second operation) demonstrates severe flow defect (arrowhead) in proximal graft limb (catheter in graft body). D, Completion antegrade angiogram after kissing stents (arrows).

Fig 2 A, Retrograde angiography force vectors (small arrows) reduce distally-based flaps against the graft wall. B, Antegrade injection reproduces physiologic flow vectors (small arrows), which can elevate such potentially flow-limiting flaps. C, Raising the graft bifurcation with kissing technique allows the ipsilateral stent to pin main body flaps against the graft wall (arrowheads) by using the contralateral stent for support (single arrowhead).
