Abstract
Stenting is a safe and efficient method for treatment of ischaemic heart disease. Nevertheless, it gives rise to some additional problems, especially in-stent restenosis. Several techniques including balloon angioplasty, restenting, rotaablation, excimer laser angioplasty, directional coronary atherectomy, cutting balloon angioplasty, brachitherapy and radioactive stents have been performed to treat in-stent restenosis. Balloon angioplasty is preferred in focal lesions (<10 mm). Restenting can be used only in selective cases. The clinical results of debulking techniques associated with balloon angioplasty in patients with long lesions are better especially in diabetic patients. In addition to these procedures, coronary bypass surgery in patients in-stent restenosis with multivessel disease seems to yield to best outcomes. On the other hand, current smoking, diabetes mellitus, unstable angina pectoris, and time to reintervention and in-stent restenosis in saphenous vein lesions are important negative predictors for re-restenosis. The main goal of the treatment of in-stent restenosis is the prevention of the restenosis. Unless this problem is solved the newer techniques will develop, and they will also carry on the newer problems.
