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...

Key points † Optimizing tracheal sealing is of clinical interest: fluid leakage past the tube cuff plays an important role in the pathogenesis of VAP. † Tapered shaped tube cuff offering a sealing zone with reduced folds and channels is a new strategy to minimize fluid leakage past the tracheal tube cuff. † Tracheal tube cuffs made from PVC show much more and faster fluid leakage than cuffs mad...

Tracheal diameter can be assessed from a thoracic radiograph, with assessment of tracheal diameter in dogs based on ratios between tracheal diameter and a skeletal measurement. Reference intervals are not, however, available for the cat. Tracheal narrowing may cause significant clinical problems, although tracheal hypoplasia in dogs may be clinically silent, and is rarely reported in cats (both...

a twenty-year-old girl was referred with tracheal stenosis (ts) which was a consequence of prolonged intubation after head injury because of previous car accident. the patient was aphasic and had normal respiration. fiberoptic bronchoscopy showed complete tracheal obstruction at second tracheal ring level. distal trachea was normal through tracheostomy tube. removal of the tracheostomy tube and...

mediastinal tracheostomy is a complex surgical procedure for the management of airway reconstruction in patients whose distal trachea is not sufficiently long to be reconstructed as cervical tracheostomy after tracheal resection for malignant diseases. in this article (study), we present our 10 year experience of this uncommon procedure in thoracic surgery ward of imam khomeini's hospital, tehr...
