A 62-years old man was admitted to emergency department suffering from chest pain. Resting ECG revealed ST elevation on inferior leads and he was diagnosed with acute inferior myocardial infarction. His past medical history revealed that a bare metal stent had been implanted in his circumflex coronary artery upon stable angina pectoris 45 months ago. Immediately performed coronary angiography d...

This report presents the extracorporeal membrane oxygenation (ECMO)-assisted surgical as a treatment of benign double tracheoesophageal fistula. The patient was a 43-year-old woman who presented the airway obstruction for 3 weeks after the esophagus metal stent implantation for the tracheoesophageal fistula 1 year ago. The airway obstruction was due to the expansion and piercing of the metal st...

This article aims to present a modified yet simple technique for the placement of implants between the mandibular foramina with the help of a radiographic stent. A radiographic stent was made on the patient’s mandibular cast on which two metal balls were fixed at the premolar area and this was then used to determine the exact position of the mental foramina with the help of a panoramic X-ray. A...

BACKGROUND Stent related occlusion and migration remains a problem despite attempts to improve stent design over this time period. Flanged polyethylene plastic stents (FPS) remains the stent of choice in most centers. Early failure of stents placed for malignant extrahepatic biliary strictures (MEBS) has not previously been studied in detail. We set out to determine the incidence and reasons fo...

BACKGROUND We describe the rationale and design for the 'PercutAneous INTervention with biodegradable-polymer based paclitaxel-eluting or sirolimus-eluting versus bare stents for de novo coronary lesions - PAINT trial'. OBJECTIVES To evaluate two novel formulations of paclitaxel-eluting stent and the sirolimus-eluting stent against a stent with the same metallic structure but without polymer ...

Figure 1 The endoscope is inserted through the distal end of Several techniques for managing migrated and misplaced self-expanding esophageal metal stents have been described.1--5 However, most of these techniques apply only when there is distal stent dislodgment. When there is proximal stent migration or misplacement, and unless there is a lasso at the distal flange, trying to reposition the s...

The clinical use of metallic expandable intravascular stents has resulted in improved therapeutic outcomes for coronary artery disease. However, arterial reobstruction after stenting, in-stent restenosis, remains an important problem. Gene therapy to treat in-stent restenosis by using gene vector delivery from the metallic stent surfaces has never been demonstrated. The present studies investig...

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...

The prospective multicenter German Drug-Eluting Stent (DES.DE) registry is an observational study to analyze and evaluate the therapeutic principle of the differential drug-eluting stents (sirolimus- and paclitaxel-eluting stents) and bare metal stents under real world conditions in the context of the German healthcare system. The baseline clinical and angiographic characteristics and follow-up...

Airway stents (silicone and metal stents) are used to treat patients with benign tracheal stenosis, who are symptomatic and in whom tracheal surgical reconstruction has failed or is not appropriate. However airway stents are often associated with complications such as migration, granuloma formation and mucous hypersecretion, which cause significant morbidity, especially in patients with benign ...
