To accomplish these goals, we will conduct a randomized clinical trial of hemodialysis patients who are referred for treatment of thrombosed A-V grafts. The patients will be randomized to be treated with thrombectomy + stent deployment or thrombectomy + angioplasty. The primary outcomes will be primary (unassisted) graft patency. The secondary outcomes will be secondary (assisted) graft patency and the cumulative cost of all access-related procedures, hospitalizations, and complications.
