background: the drug-eluting stent (des) decreases the rate of coronary restenosis and re-obstruction. the aim of this study was to assess prospectively the effectiveness of the new generation des on the left ventricular (lv) systolic and diastolic functions in patients with isolated severe proximal left anterior descending (lad) coronary artery stenosis. methods: a prospective study was conduc...

Abstract Aim Extra-Anatomical Detour Stents offer a viable modality of decompression particularly in the context malignancies; with absent need for changes stents, cosmetically better than nephrostomies and fewer admissions associated blockages/infections. Our aim was to assess safety feasibility performing detour stents district general hospital. Method A review prospectively collected data on...

Drug-eluting stents reduce the occurrence of in-stent restenosis and the need for subsequent target vessel revascularization compared with bare-metal stents. However, the safety of drug-eluting stents has been called into question because of an apparent increase in late stent thrombosis, a frequently fatal event. A substantial body of research has focused on determining the magnitude of these c...

BACKGROUND Benign biliary strictures may be a consequence of surgical procedures, chronic pancreatitis or iatrogenic injuries to the ampulla. Stents are increasingly being used for this indication, however it is not completely clear which stent type should be preferred. METHODS A systematic review on stent placement for benign extrahepatic biliary strictures was performed after searching PubM...

INTRODUCTION AND OBJECTIVES To compare the 3-year incidence of major events in patients with bifurcation lesions treated with provisional sirolimus-eluting stents vs everolimus-eluting stents. METHODS A pooled analysis of 2 prospective randomized trials with similar methodology (SEAside and CORpal) was performed. In these trials, 443 patients with bifurcation lesions were randomly assigned to...

OBJECTIVES Initial and late results after implantation of Freedom stents, a balloon expandable stainless steel coil stents were evaluated. METHODS From Jun. 1996 to Nov. 1997, we implanted 123 Freedom stents in 122 lesions in 117 patients and performed follow-up coronary angiograms at 7.0 +/- 3.6 months after stents placement. Clinical courses after stenting and follow-up coronary angiographi...

BACKGROUND Experimental studies have demonstrated that 32P radioactive stents reduce neointimal formation at 28 days in porcine iliac and coronary arteries. Our objective was to determine the long-term dose-response effects of 1.0- to 12.0-microCi 32P radioactive stents in a porcine atherosclerotic coronary model. METHODS AND RESULTS Control (n=19) and 1.0- to 12.0-microCi 32P radioactive (n=...

Background and Purpose—Stent-assisted coiling has expanded the treatment of intracranial aneurysms, but the rates of procedure-related neurological complications and the incidence of angiographic aneurysm recurrence of this novel treatment are not yet well known. We present our experience with stent-assisted coiling with special emphasis on procedure-related neurological complications and incid...

BACKGROUND There is evidence that endothelial coverage of drug-eluting stents might be delayed or absent, a risk factor for late thrombotic events. We studied the effects of different drug-polymer-device iterations on endothelium-dependent coronary vasomotion. Systemic markers of endothelial inflammation were correlated with coronary vasomotor changes. METHODS AND RESULTS Patients with paclit...
