Abstract:
Objective To evaluate therapeutic effects of endovascular therapy for in-stent restenosis of superficial femoral artery,and the risk factors of restenosis of re-intervention therapy.Methods We retrospectively summarized the clinical data of 35 patients(38limbs)who suffered from in-stent restenosis of superficial femoral artery(SFA)stent from 2010 to 2012.Results 35 patients (38 limbs)were enrolled in this study,there were 24 males and 11 females.Mean age was (68 ±8)years.The success rate of endovascular therapy was 89.5％ (34/38),including in-stent angioplasty in 14 limbs,in-stent and beyond-stent angioplasty in 5 limbs,in-stent angioplasty and beyond-stent re-stenting in 15 cases.The primary patency and sencondary patency rate for 6,12 and 24 months was 65.2％,46.5％,46.5％,and 87.5％,80.2％,55.8％ respectively.The independent risk factors for re-obliteration were age ＞ 70 years (P ＜ 0.05) and diabetes mellitus (P ＜ 0.05).Conclusions Endovascular therapy is effective and safe in treatment in-stent restenosis of superficial femoral artery.The long-term in-stent patency is not satisfactory,with age ＞ 70 years and diabetes mellitus as independent risk factors.
