Covered stent for the treatment of recurrent bilateral renal artery in-stent restenosis

The optimal treatment for renal artery in-stent restenosis (ISR) is not well established. Reintervention with different strategies including balloon angioplasty, cutting-balloon angioplasty, additional stenting with bare-metal, drug-eluting or covered stents and brachytherapy are effective in achieving immediate angiographic success. However, recurrent ISR rates are high irrespective of treatment strategy. We present a case describing the use of a covered stent for the treatment of recurrent bilateral renal artery ISR after bare-metal and drug-eluting stent implantation and cutting-balloon angioplasty.
