This study was performed to evaluate the outcome of percutaneous revascularization in 'edge restenoses' developing after radioactive stent implantation in de novo and in-stentlesions. Twenty-one consecutive patients undergoing target lesion revascularization (TLR) at any follow-up after phosphorus-32 radioacttive stent implantation were included in this study. We assessed the incidence of death, myocardial infarction, repeated TLR and recurrent angina over the following 18 months. After 6 months, TLR rate was 28.6%, and no stent thromboses, deaths or Q-wave myocardial infarctions occurred. Among the patients with TLR there were significantly more subjects who had received a radioactive stent in a previous in-stent restenosis (66.7% vs. 0% in patients without second restenosis; P < 0.001), or who had received two radioactive stents (83.3% vs. 33.3%; P = 0.038).After 18 months, TLR rate was 33.3%, and two patients (9.5%) had died. Restenosis after intravascular radiotherapy can be safely treated by percutaneous interventional techniques, yielding an acceptable clinical result within 18 months.
