BACKGROUND Although durable polymer coated drug-eluting stents (DES) are standard care in percutaneous coronary interventions, new stent platforms employing biodegradable polymer based drug delivery are increasingly being used in clinical practice. AIM To evaluate the short- (28 days) and medium-term (90 days) vascular effects of the new biodegradable polymer coated sirolimus-eluting stent - ...

The current technical step forwards in metallic stents (MS), bare metal stents (BMS) and drug-eluting stents (DES) respectively led interventional cardiologists to a rude therapeutic attitude, that even the most complex coronary lesions are being treated with angioplasty plus stents (TCA). About a third of all the patients with multivessel disease (MVD) in Europe are being treated with TCA inst...

The use of self-expanding metal stents can markedly improve the care of patients with inoperable oesophageal malignancy. The stents can be easily introduced without the need for general anaesthesia. They have fewer complications during insertion than rigid stents and fewer complications than laser therapy. With these stents lumens of up to 2.5 cm are easily obtainable. The article considers the...

Metal stents and, more recently, polymer-coated metal stents are used to stabilize dissections, eliminate vessel recoil, and guide remodeling after balloon angioplasty and other treatments for arterial disease. Bioresorbable polymeric stents are being developed to improve the biocompatibility and the drug reservoir capacity of metal stents, and to offer a transient alternative to the permanent ...

The introduction of intracoronary stents represented a major advance in interventional cardiology. While bare metal stents set the benchmark for improved safety over angioplasty, intimal hyperplasia and subsequent restenosis were important limitations. First-generation drug-eluting stents demonstrated significant improvements in efficacy, but not necessarily safety, and further technologic deve...

CONTEXT The efficacy and safety of drug-eluting stents compared with bare-metal stents remains controversial in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). OBJECTIVE To compare stents eluting biolimus from a biodegradable polymer with bare-metal stents in primary PCI. DESIGN, SETTING, AND PATIENTS A prospectiv...

background: carotid artery stenting is now used as an alternative to surgical endarterectomy. this study was done to assess the feasibility, safety, and immediate and late clinical outcomes in patients undergoing carotid stenting . methods: between july 2008 and december 2009, a total of 40 patients (20 male, mean age: 65 ± 11 years, 19 symptomatic, and 90% high risk for endarterectomy) underwe...

which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. We read with great interest the study reported by Ra-bani (1). The author reported their experiences in endo-scopic management of forgotten ureteral stents with large burden stone encrustation. As the author stated, ureteral stents are widely used in urology practices. How...

Everolimus-eluting stents (EES) have become the most commonly implanted coronary stents worldwide. This review describes and analyzes the clinical data supporting the use of EES, focusing primarily on published, randomized, controlled trials. Everolimus-eluting stents have been shown to have less restenosis, stent thrombosis, and periprocedural myocardial infarction compared with earlier genera...

Bare metal stents enabled a reduction in the risk of early procedural complications and restenosis in comparison with balloon angioplasty alone, but introduced a new and device-specific iatrogenic condition, ie, in-stent restenosis due to increased neointimal hyperplasia. Sirolimus- and paclitaxel-eluting stents reduce restenosis and the need for new revascularizations in comparison with bare m...
