We report a case of a 51-year-old woman with an esophageal lichen planus (ELP) stricture refractory to medical therapy and endoscopic stricture dilation. A multidisciplinary decision was made to place an esophageal fully covered metal stent. The stent was removed 6 weeks later and the patient is doing well on 3-month follow up. We show that a removable esophageal stent is an option after standa...
The purpose of this multi-center, non-randomized, and open-label clinical trial was to determine the non-inferiority of diamond-like carbon (DLC)-coated cobalt-chromium coronary stent, the MOMO DLC coronary stent, relative to commercially available bare-metal stents (MULTI-LINK VISION®). Nineteen centers in Japan participated. The study cohort consisted of 99 patients from 19 Japanese centers w...
BACKGROUND We sought to identify gene polymorphisms that confer susceptibility to in-stent restenosis after coronary artery bare-metal stenting in a Central European population. METHODS 160 controls without post-percutaneous coronary intervention in-stent restenosis were matched for age, sex, vessel diameter, and diabetes to 160 consecutive cases involving in-stent restenosis of the target le...
T wenty years ago, Drs. Patrick Serruys and Carlo Di Mario wrote an editorial in Circulation titled “Who Was Thrombogenic: The Stent or the Doctor?” (1), that discussed optimal stent implantation technique. They highlighted the critical roles played by both the use of intravascular ultrasound to optimize stent implantation and the administration of dual antiplatelet therapy (DAPT) to prevent me...
Endobronchial stent placement is a novel therapy for treatment of iatrogenic tracheal tears. A review of the available literature shows surgery and long-term intubation being the established treatment strategy. We describe the case of a 64-year-old woman with a tracheal rupture following endotracheal intubation for routine surgery. Pneumo-mediastinum and chest pain were the predominant symptoms...
Coronary stent implantation has significantly improved percutaneous coronary intervention and enabled the management of early complications of plain balloon angioplasty (POBA). By preventing elastic recoil and constrictive remodeling, coronary stent implantation decreases the frequency of restenosis after percutaneous coronary intervention. However, a new complication has accompanied these impr...
Atheromatous and thrombotic embolization during percutaneous coronary revascularization is a feared complication that may cause impaired myocardial reperfusion even with a patent epicardial vessel. The MGuard stent is a cobalt chromium bare metal stent with a porous net attached to its outer surface that has been designed to prevent thrombus fragmentation and distal embolization during stent im...
Drug-eluting stents (DES) have reduced the rate of repeated revascularization of target lesions. For this reason, DES are considered to be superior to bare-metal stents in reducing the restenosis rate. However, some problems have been reported after implantation of DES. One of them, stent thrombosis, has arisen as a fatal complication. Dual antiplatelet therapy is recommended for at least 12 mo...
BACKGROUND Hemorrhagic complications during EUS-guided pseudocyst drainage can occur, because the vessels on the internal wall of the pseudocyst might be compressed by the fluid and thus not visible on color Doppler or even power Doppler EUS. CASE PRESENTATION We report a case of an immediate internal spurting arterial bleeding precipitated during EUS-guided pseudocyst drainage which stopped ...
BACKGROUND The safety and efficacy of the slow-release, polymer-based, paclitaxel-eluting stent after implantation in a broad cross section of de novo coronary lesions at 1 year are unknown. METHODS AND RESULTS In the TAXUS-IV trial, 1314 patients with single de novo coronary lesions 10 to 28 mm in length, with reference-vessel diameter 2.5 to 3.75 mm, coverable by a single study stent, were ...
