Randomization: All subjects with a recent thrombosed AV graft who meet the inclusion and exclusion criteria and consent to participation in the study will be randomized to either the angioplasty arm or the angioplasty plus stent deployment arm. Patients will be taken to the interventional suite in the Interventional Radiology department. Randomization will occur only after ascertaining that that graft flow has been restored and that there is a >50% stenosis at the venous anastomosis. Randomization will be accomplished by unsealing a sequentially numbered opaque envelope that contains the randomization allocation for that subject.
