摘　　要：尽管药物涂层支架较金属裸支架可以明显降低再狭窄率,但随着临床中的广泛应用,药物支架术后亦有10%发生支架内再狭窄,具体机制不明,主要与介入手术操作和涂层药物、支架本身等有关,多发生支架内局限性狭窄,亦有弥漫病变,最佳治疗手段尚存在争议,再次药物支架置入及血管内放射治疗等都是不错的选择。Although drug-eluting stents have a decreased rate of restenosis compared with metal stents, in-stent restenosis after implanting drug-eluting stents does still happen. Restenosis can be focal in stent, and also diffused. The mechanism of restenosis is not yet clear. It is possible that most factors have something to do with the operation . The best treatment for restenosis is disputed.
