A retrospective review of 11 French academic institutions (University Association for Research in Vascular Surgery—AURC) from 2005 to 2017. One hundred and twenty-one transfemoral carotid artery stent (TF-CAS) procedures were performed 112 patients (31% symptomatic). The mean interval between irradiation TF-CAS was 15 years. Duplex ultrasound examination at 1, 6, 12 months, annually thereafter....

The new enemy of percutaneous intervention is in-stent restenosis. He joins the old enemy, restenosis after balloon angioplasty, who, after 21 years of resistance, refuses to capitulate. Unlike restenosis after balloon angioplasty, in-stent restenosis is a consequence almost entirely of tissue hyperplasia, occurring principally around the points where the stent struts impinge upon the artery wa...

Coronary stent fractures have been suggested as a potential new mechanism of restenosis. The mechanical properties of stents were designed not only to prevent vessel recoil, but also to resist the mechanical stress of vessel movement over millions of cardiac cycles. We present a case in which mechanical stress may have contributed to the fracture of a stent implanted in a saphenous vein graft (...

AIMS The purpose of this study was to evaluate the Genous(TM) endothelial progenitor cell capturing stent vs. the Taxus Liberté paclitaxel-eluting stent in patients with de novo coronary lesions with a high-risk of coronary restenosis. METHODS AND RESULTS We randomly assigned 193 patients with lesions carrying a high risk of restenosis to have the Genous stent or the Taxus stent implanted. Le...

OBJECTIVE The aim of this study was to test for association between MHC2TA gene polymorphisms and risk for restenosis after coronary stent placement in a group of Mexican patients. METHODS The MHC2TA-168A>G (rs3087456), 1614C>G (rs4774), and 2536G>A (rs2229320) single nucleotide polymorphisms were genotyped using 5' exonuclease TaqMan genotyping assays in a group of 202 patients, who underwen...

Purpose. The long-term efficacy of carotid artery stenting is debated. Predictors of stent restenosis are not fully investigated. Our aim was to assess the incidence of long term restenosis after CAS and to identify some predictors of restenosis. Methods. We retrospectively selected 189 treated patients and we obtained the survival Kaplan-Meier curves for overall survival, for freedom from stro...

BACKGROUND Edge restenosis is a major problem after radioactive stenting. The cold-end stent has a radioactive mid-segment (15.9 mm) and non-radioactive proximal and distal 5.7 mm segments. Conceptually this may negate the impact of negative vascular remodelling at the edge of the radiation. METHOD AND RESULTS ECG-gated intravascular ultrasound with three-dimensional reconstruction was perfor...

The clinical success of balloon angioplasty is limited by restenosis, which occurs in up to 50% of patients. Lumen compromise and restenosis are caused by acute elastic recoil and late constrictive remodeling and to a lesser degree by neointimal hyperplasia [1,2]. The application of bare metal stents (BMS) has revolutionized percutaneous coronary interventions by reducing the rate of clinical c...
