The authors report a case of renal artery stent restenosis exacerbated by the likely displacement of multiple bare metal stents that had been contiguously deployed 3 months previously. The unusual features of this case are discussed along with putative mechanisms of stent displacement in visceral arteries. The restenotic disease was successfully treated with excimer laser atherectomy and cutting balloon atherotomy.
