BACKGROUND Carotid artery stenting has recently been recommended as an alternative to carotid endarterectomy by some clinicians. OBJECTIVE To evaluate success rate, as well as in-hospital and 30-day adverse events in our first experience in Iran for carotid artery stenting with protection devices. METHODS From December 2003 through July 2004, we performed 12 consecutive (9 males and 3 femal...

BACKGROUND AND PURPOSE We investigated predictors for acute and persisting periprocedural ischemic brain lesions among patients with symptomatic carotid stenosis randomized to stenting or endarterectomy in the International Carotid Stenting Study. METHODS We assessed acute lesions on diffusion-weighted imaging 1 to 3 days after treatment in 124 stenting and 107 endarterectomy patients and les...

BACKGROUND AND PURPOSE Percutaneous transluminal angioplasty combined with vascular stenting is currently being assessed in the treatment of patients with symptomatic, severe carotid stenosis. The immediate cerebral hemodynamic effects resulting from stenting are not fully understood. This article describes a novel finding: abnormal leptomeningeal enhancement after stenting shown by MRI. METH...

Direct coronary stenting without balloon predilatation may cause lower postprocedural minor myocardial injury in comparison to conventional stenting with balloon predilatation.Plasma brain natriuretic peptide (BNP) is increased in acute myocardial ischaemia. 40 patients with single vessel and single lesion coronary artey disease who underwent elective stent implantation were divided into Group ...

OBJECTIVE To assess the efficacy, safety and advantage of direct coronary stenting versus traditional angioplasty and stenting. METHODS From May 2000 to June 2001, 486 patients underwent PTCA procedure. One hundred fifteen (24%) were considered candidates for direct stenting. Out of 150 coronary lesions, 119 (79%) had direct coronary stenting. In 5% patients stent could not be passed across t...

Direct stenting without antecedent dilatation may reduce procedural time, costs, and radiation exposure, and may result in less vessel injury. The purpose of this investigation was to compare immediate and long-term clinical and angiographic outcomes of direct stenting with stent placement after initial balloon dilation. Three hundred thirty-five symptomatic patients with single or multiple cor...

BACKGROUND Several endovascular revascularization strategies have been described for the treatment of acute ischemic stroke (AIS). One of them is stenting when a very narrow stenosis with high reocclusion risk remains after recanalization. This study describes the risk of symptomatic intracerebral hemorrhage (SICH) after emergent stenting in patients with AIS treated with endovascular therapies...

Background—The purpose of this study was to compare long-term outcomes of coronary stenting in all lesions (elective stenting) or only in lesions with inadequate morphological and functional results after balloon angioplasty (guided PTCA). Methods and Results—Treatment of multivessel disease, with any lesion length and vessel size, was allowed provided that all lesions were suitable for stent i...

Objective: We evaluated the short and long-term effect of peri-interventional dabigatran therapy on vasomotion, endothelialization, neointimal formation in a porcine coronary artery stenting model. Background: Stenting arteries induces local inflammation, impairs vasomotion delays endothelialization. Methods: Twenty-eight animals underwent percutaneous intervention (PCI) with drug eluting stent...

BACKGROUND A number of studies have evaluated the efficacy of deferred stenting vs immediate stenting in patients with ST-segment elevation myocardial infarction, but the findings were not consistent across these studies. This meta-analysis aims to assess optimal treatment strategies in patient with ST-segment elevation myocardial infarction. METHODS AND RESULTS We searched the PubMed, EMBASE...
