Drug-eluting stent implantation for treatment of recurrent renal artery in-stent restenosis.

Percutaneous renal artery stenting has become the treatment of choice for renal artery stenosis. In-stent restenosis (ISR) still remains a persistent problem. Drug eluting stents have significantly reduced the incidence of ISR in coronary arteries. We report a case in which recurrent renal ISR was successfully treated with paclitaxel-eluting stent implantation, using intravascular ultrasound guidance, with maintained stent patency at 6 months.
