In-stent restenosis remains one of the main drawbacks of stenting the femoropopliteal segment, and leads to stent failure and repeated interventions. A variety of endovascular techniques have been investigated so far to reduce this phenomenon, including plain angioplasty, atherectomy, new stent deployment, cutting balloons and cryoplasty but without satisfactory mid- and long-term results. More recently drug-eluting devices have been applied in femoropopliteal in-stent restenosis with promising results. The aim of this review is to analyse the indication and effectiveness of those endovascular techniques for the treatment of in-stent restenosis.
