Drug-eluting stent insertion in the treatment of in-stent renal artery restenosis in three renal transplant recipients.

Percutaneous transluminal angioplasty (PTA) with or without stent insertion is the treatment of choice in transplant renal artery stenosis. However, in-stent restenosis occurs in as many as 13% of patients after PTA and stent insertion. This article describes three patients with recurrent transplant renal artery in-stent stenosis who were treated with paclitaxel-eluting stents. In two patients, the transplant renal artery remained patent after insertion of the drug-eluting stent (DES), and one patient required balloon angioplasty 7 months after the DES was inserted.
