冠脉支架内再狭窄治疗策略研究的进展

Research progress of therapeutic strategy of coronary in-stent restenosis

尽管药物洗脱支架(DES)已经得到广泛应用,支架结构的设计也不断改良,植入DES患者支架内再狭窄(ISR)发生率仍高达10%。目前用于治疗ISR的主流选择包括切割球囊和棘突球囊、药物涂层球囊、斑块销蚀技术、裸金属支架及DES重复置入术。本文就ISR的治疗策略研究进展作一综述,旨在为ISR治疗提供新思路。

Although drug-eluting stents(DES)have been widely used and the design of stent structure has been continuously improved,incidence rate of in-stent restenosis(ISR)in patients undergoing DES implantation is still as high as 10%.The current mainstream options for ISR treatment include cutting balloons and spinous process balloons,drug-coated balloons,plaque erosion techniques,bare metal stents and DES repeated implantation.The present article made a review on research progress of strategies of ISR treatment,aiming at providing new thinking for ISR treatment.
