Hemodialysis AV graft angioplasty

The sequence of angiograms shows the treatment of venous stenosis (arrow) associated with an AV graft. A severe stenosis can be seen at the venous anastomosis of an AV graft (A). With inflation of an angioplasty balloon across the lesion, the lesion (arrow) is apparent (B). Total effacement of the angioplasty balloon (arrow) can be seen with the balloon inflated to nominal pressure (C). Completion venography (D) shows no residual stenosis (arrow).
