Brachytherapy for In-Stent Restenosis A Distant Second Choice to Drug-Eluting Stent Placement

摘要

THE GREAIESI RECENT MECHANICAL ADVANCE IN PER-cutaneous coionaiy revasculaiization (PCR) has been the development of bate-metal stents, which compared with traditional balloon angioplasty substantially reduce angiographic restenosis and the need for repeat target vessel revascularization (TVR) Stents pro-vide a larger arterial lumen diameter immediately postpro-cedure (acute gain), although their drawback is an increased reparative response of neointimal formation (late loss) Fortunately, the net gain remains greatest with stents compared with other PCR devices#
