Endoscopic bilateral stenting using conventional metal stents is considered to be technically difficult in patients with malignant hilar bile duct obstruction because the second stent is not easily inserted through the cell of the first stent wall in the bile duct [1]. A variety of new self-expandable metal stents (SEMS) specially designed for stent-in-stent procedures to facilitate bilateral s...

Esophageal stent insertion has been used as a well-accepted and effective alternative to manage and improve the quality of life for patients diagnosed with esophageal diseases and disorders. Current stents are either permanent or temporary and are fabricated from either metal or plastic. The partially covered self-expanding metal stent (SEMS) has a firm anchoring effect and prevent stent migrat...

A 60-year-old man, who had claudication in his right limb due to total occlusion of the right superficial femoral artery, received bare metal stents. Although the bare metal stents in the superficial femoral artery did not show restenosis 5 years after stent implantation, angiography revealed significant in-stent restenosis when he developed right critical limb ischemia at 8 years post implanta...

PURPOSE To better understand the performance of four commercially available neurovascular stents in intracranial aneurysm embolization, the stents were compared in terms of their basic morphological and mechanical properties. MATERIALS AND METHODS Four different types of stents that are currently being used for cerebral aneurysm embolization were prepared (two stents per type). Two were laser...

We describe the case of an esophagopericardial fistula generated after endoscopic submucosal dissection in a patient affected by a superficial esophageal squamous cell carcinoma immediately treated with percutaneous pericardial drainage and placement of a partially covered self-expanding metal stent that has been removed using the stent-in-stent technique after 35 days.

Coronary artery aneurysm (CAA) formation is an uncommon but potentially life-threatening event after coronary balloon angioplasty or stent implantation. In this report, we present a case of a patient who had a cockscomb-like aneurysm after bare metal stent implantation which was successfully treated with a coronary graft stent.

An expandable metal stent inserted via a long term tracheostomy successfully relieved life threatening respiratory obstruction due to benign tracheal stenosis. Later the patient's tracheostomy suction catheter became stuck on the stent and dislodged it. The stent was removed electively, without damaging the trachea, with a rigid biopsy forceps.

Over the past decade, drug-eluting stents (DES) have greatly transformed the field of interventional cardiology. Generally, three components are included in a DES system: a metal stent platform, a drug carrier or so called ‘stent coating’ and a drug. As such, stent coating plays an important role in the performance of DES. This article will review the evolution of stent coatings and their role ...

Coronary pseudoaneurysm after bare-metal stent implantation is a rare event. Observation, surgical resection, or implantation of another stent, bare or covered, are alternative and equivalent management options. Since no option prevails over the other, the most appropriate treatment should be evaluated in every single patient. We report the case of a pseudoaneurysm within a stent with diffuse r...

A lthough introduction of drug-eluting stent (DES) use substantially reduced early target lesion revascularization (TLR) as compared to bare-metal stent use by restricting development of neointima hyperplasia, DES have been associated with increased the risk of stent thrombosis and TLR after 1 year, that is, very late stent failure (VLSF) (1). The incidence of VLSF has been reduced with the use...
