股浅动脉支架内再狭窄的危险因素研究进展

Risk factors for superficial femoral artery in-stent restenosis: recent progress in research

股浅动脉(SFA)支架植入血管成形术是针对SFA狭窄或闭塞性病变的腔内常用治疗方法,但支架植入术后股浅动脉支架内再狭窄(superficial femoral artery in-stent restenosis,SFA-ISR)的发生率很高,由于大多数的患者直到出现严重临床症状才会再次寻求诊治,所以对于控制支架内再狭窄(ISR)相关危险因素至关重要。近年对SFA-ISR的危险因素研究不断深入,本文就其解剖学特点、病理生理学基础、危险因素研究进展作一综述。

Superficial femoral artery stent implantation has been a common endovascular treatment for the stenosis or occlusive lesions of superficial femoral artery. Because the incidence of superficial femoral artery in-stent restenosis （SFA-ISR） is high and usually most clinical patients will not seek for medical consultation and treatment until they developed severe clinical symptoms, it is extremely important to effectively control ISR- related risk factors for patients who have received superficial femoral artery stent implantation. In recent years, many valuable studies on the risk factors of SFA-ISR have been conducted. This paper aims to make a detailed review concerning the anatomical characteristics, pathophysiological basis and risk factors of SFA-ISR.
