In-stent restenosis in a renal artery (RA) of a solitary functioning kidney is a serious complication of RA stenting. Drug-eluting balloons (DEB) have emerged as a novel way to manage restenosis. In this paper, the authors reported the first use of a DEB in the treatment of severe in-stent restenosis and thrombosis of a drug-eluting stent deployed in a RA. The patient presented with oligo-anuria and a serum creatinine (Scr) of 9 mg/dL that improved back to baseline of 2 mg/dL after the successful procedure. The optimal use of DEB in similar cases will have to be determined by larger clinical trials.
