股腘动脉支架内再狭窄的腔内治疗进展

近年来,随着血管内支架置入术在股腘动脉狭窄与闭塞疾病中的广泛应用,支架内再狭窄(ISR)的发生率也在逐年上升。虽然药物涂层球囊(DCB)的使用减轻了ISR的患病率,但ISR的治疗仍然是一个难点。虽然普通球囊(POBA)、切割球囊、冷冻球囊,再次支架植入已经在ISR的治疗中得到应用,但效果均不满意。而减容技术以及DCB分别有一定的局限性,将两者联合使用可以发挥各自的优势,可能是未来治疗股腘动脉ISR的有效途径。

Advances in endovascular treatment of in-stent restenosis of femoropopliteal artery

In recent years, with the extensive use of endovascular stenting in treatment of femoropopliteal artery stenosis and occlusion disease, the in-stent restenosis (ISR) is increasingly becoming a growing problem. Although the use of drug-coated balloon (DCB) reduces the prevalence of ISR, the treatment of ISR remains a clinical challenge. Despite that, the plain old balloon angioplasty (POBA), cutting balloon, frozen balloon, and re-stent implantation have been applied in the treatment of ISR, but the results are not satisfactory. Both debulking technique and DCB have certain limitations. However, their combination can exert their respective advantages, which may be an effective way to treat ISR of the femoropopliteal artery in the future.
