BACKGROUND AND PURPOSE Despite advances in mechanical thrombolysis for acute stroke, recanalization rates remain approximately 50%-60%. Technologic improvements allowed safe intracranial delivery of stents. To study the feasibility of stent-assisted recanalization for acute stroke, we deployed self-expanding or balloon-mounted stents in 2- to 3.5-mm canine vessels acutely occluded with clot emb...

PURPOSE Drug-eluting stents are commonly used for percutaneous coronary intervention. Despite excellent clinical efficacy, the association between drug-eluting stents and the risk for late thrombosis remains imprecisely defined. METHODS We performed a meta-analysis on 14 contemporary clinical trials that randomized 6675 patients to drug-eluting stents (paclitaxel or sirolimus) compared with b...

traumatic injuries to the subclavian-axillary artery, although uncommon, are associated with high morbidity and mortality rates if not managed promptly. the emergence of endovascular techniques offers an alternative to the surgical management of these injuries. we herein present 4 cases of traumatic subclavian-axillary artery injury with limb ischemia successfully managed via the endovascular a...

BACKGROUND There is no consensus regarding the safety and efficacy of drug-eluting stents, as compared with bare-metal stents, in patients with ST-segment elevation myocardial infarction who are undergoing primary percutaneous coronary intervention (PCI). METHODS We randomly assigned, in a 3:1 ratio, 3006 patients presenting with ST-segment elevation myocardial infarction to receive paclitaxe...

Coronary stent thrombosis is a rare event leading to ST segment elevation myocardial infarction and death. Although early thrombosis of drug-eluting and bare metal stents is relatively frequent, simultaneous thrombosis of bare metal coronary stents has rarely been reported. Here, we present a case of simultaneous subacute thrombosis of two bare metal stents in different coronary arteries ea...

In this work, stents were produced from natural origin polysaccharides. Alginate, gellan gum, and a blend of these with gelatin were used to produce hollow tube (stents) following a combination of templated gelation and critical point carbon dioxide drying. Morphological analysis of the surface of the stents was carried out by scanning electron microscopy. Indwelling time, encrustation, and sta...

INTRODUCTION Balloon expandable stents are an integral part in the catheter treatment of congenital heart disease. In the growing child, stents require dilatation to greater diameters over time. The Cook Formula stent is a recent 316 stainless steel open-cell design licensed for peripheral vascular work. METHODS Following extensive ex vivo studies, 112 stents were implanted in 97 children [me...

Advanced endoscopy can be used to insert stents (hollow tubes) into various sites of the gastrointestinal tract and this has proved to be a major therapeutic advance. Stents can hold open strictured areas in the oesophagus, the biliary tree, the colon and the gastroduodenal region. Stents are usually positioned in order to overcome stricturing associated with cancerous tumours. They are used as...

Treating multivessel disease in the era of coated stents: introduction N umerous reports in cardiology congresses and journals deal with multivessel treatment with percutaneous transluminal coronary angioplasty (PTCA) and stenting. Clinical practice, however, is very different with more than 90% of all percutaneous revascularisation procedures in Europe and the USA limited to single vessel trea...

Expandable metallic stents seemed to be a good method in tuberculous bronchial stenosis that does not respond to medical therapy. But there was no long-term follow-up study after stents insertion in tuberculous bronchial stenosis. We report a case of obstruction after successful Gianturco metallic stents insertion due to tuberculous bronchial stenosis.
