[In 2003, what are the indications of brachytherapy in coronary arteries?].

Significant results obtained with coated stents in "de novo" coronary lesion treatment, particularly in complex lesions, have substituted brachytherapy indications. However, curitherapy results in diffuse or proliferative in-stent restenosis treatment show a significant reduction (30-50%) of restenosis and major adverse cardiac events. So, without sufficient scientific proofs with active stents in this indication, curitherapy is the only validated and authorized treatment of second diffuse or proliferative in-stent restenosis.
