A 9-year-old girl who had received an orthotopic liver transplant for cryptogenic cirrhosis at the age of 5 years was admitted for the evaluation of elevated transaminases. Transabdominal ultrasound demonstrated intrahepatic biliary dilatation. Liver biopsy ruled out organ rejection, and endoscopic retrograde cholangiopancreatography (ERCP) confirmed the presence of a focal anastomotic strictur...

We read the interesting article by Schneiders et al, entitled “A Flow-Diverting Stent Is Not a Pressure-Diverting Stent.” The authors measured intra-aneurysmal pressure before, during, and after placement of a flow-diverting (FD) stent and found that the pressure inside the aneurysm momentarily decreased during placement but was restored to baseline values within minutes. They agreed with the a...

When performing percutaneous coronary revascularization, physicians nearly always supplement balloon angioplasty with a stent.1 This decision is based on evidence that stent implantation enhances the procedural success and durability of angioplasty. Benefits of stenting, compared with balloon angioplasty, include a reduction in the incidence of lesion recurrence, manifested as reduced need for ...

AIMS To investigate the outcome of a real world diabetic patient cohort treated with bare metal stents (BMS), sirolimus-, or paclitaxel-eluting stents (SES and PES, respectively). Due to the different mechanisms of action of both drugs it is currently unknown which device is the best option to treat these high-risk patients. METHODS AND RESULTS The study compares the 2-year clinical outcome o...

Although safety profiles of sirolimus-eluting stents do not seem to differ in short-to-medium term from those of bare-metal stents, late stent thrombosis after deployment of drug-eluting stents has emerged as a potential safety concern in the era of high-pressure stent implantation. Here, we describe the case of a patient with acute myocardial infarction due to stent thrombosis of a sirolimus-e...

background: recently, different investigators have studied the possibility of radiation therapy in restenosis prevention and have shown promising results. in this study a unique radioactive source for intra vascular brachytherapy (ivbt) was investigated. the two-dimensional dose distribution in water for a 32p ivbt stent has been calculated. the pure beta emitter source 32p has been coated on p...

BACKGROUND Currently, endovascular treatment is indicated to treat femoropopliteal lesions ≤15 cm. However, the Achilles' heel of femoropopliteal endovascular repair remains restenosis. Paclitaxel eluting stents have shown promising results to prevent restenosis in femoropopliteal lesions compared to percutaneous transluminal angioplasty. A recently released prospective registry using a newer g...

balloon tamponade vs esophageal stent in controlling acute refractory variceal bleeding: A multicenter RCT. Management of malignant stricture of the esophagogastric junction with a newly designed self-expanding metal stent with an antireflux mechanism. Superiority of anti-reflux stent compared with conventional stents in the palliative management of patients with cancer of the lower esophagus a...

Biliary self-expandable metal stents (SEMS), a group of non-vascular stents, have been used in the palliative management of biliary obstruction around the world. However, there are still unmet needs in the clinical application of biliary SEMS. Comprehensive understanding of the SEMS is required to resolve the drawbacks and difficulties of metal stent development. The basic structure of SEMS, in...
