随着药物洗脱支架(Drug Eluting Stent,DES)的出现,再狭窄的问题得到进一步的有效控制,目前的临床证据表明DES总的再狭窄率已经在10%以下。但DES的支架内再狭窄ISR仍是临床介入治疗面临的重要问题。1DES后支架内再狭窄的发生率有资料显示〔1-2〕,在以下病变中DES的再狭窄率均超
With the advent of drug-eluting stents (DES), the problem of restenosis has been further effectively controlled, and current clinical evidence suggests that the overall rate of restenosis has been below 10%. However, in-stent restenosis with DES remains an important issue in clinical intervention. 1DES stent restenosis within the incidence of data show that 〔1-2〕, the following lesions in the restenosis rate were ultra-DES
