Clinical evaluation of radioactive stents

Abstract

Restenosis, the major problem after stent implantation, is caused by in-stent neointimal hyperplasia. A number of metbods and techniques have been studied during the last ten years to address tbis issue, but in-stent restenosis has remained at a rate of 15-25% in most of tbe clinical trials. Several experimental and clinical trials showed that brachytherapy, following a balloon angioplasty or stent implantation, reduced restenosis by inhibiting neointimal hype
