Yes: A failed av fistula can be from either clot or "stenosis". A thrombectomy can be performed if the clot is new, a stenosis can be dilated with a balloon tipped catheter. Unfortunately, av fistula failure commonly recurs in the same fistula and usually necessitates the creation of a new one in time.
