background the transjugular intrahepatic portosystemic stent-shunt (tipss) builds a shortcut between the portal vein and a liver vein, and represents a sophisticated alternative to open surgery in the management of portal hypertension or its complications. objectives to describe clinical experiences with a low-profile nitinol stent system in tipss creation, and to assess primary and long-term s...

khataminia g, md*; keramati ag, md ahvaz jondi shapoor university of medical sciences, ahvaz, iran *corresponding author: [email protected] purpose: to report the demographics and clinical profile, and outcomes of canalicular laceration repaired with mini monoka monocanalicular stent. method: all patients who had undergone canalicular laceration repair over 4 years (2004-2008) at imam khom...

OBJECTIVE The risk of in-stent restenosis can be considerably reduced by stents eluting cytostatic compounds. We created a novel drug-eluting stent system that includes several new features in the rapidly evolving field of stent-based drug delivery. METHODS AND RESULTS The aim of the present study was the preclinical evaluation of a stent-coating system permitting individual, on-site coating ...

pancreatic stent proximal migration is a well known complication of pancreatic duct stenting, which occurs in about 5-6% of cases. serious complications should be avoided by retrieval of the stent via different endoscopic techniques. we report a new technique previously reported only once (in a pancreatic duct with underlying pathology), to remove the proximally migrated pancreatic stent in a n...

BACKGROUND AND PURPOSE Endovascular treatment of wide-neck, complex, and distally located cerebral aneurysms is a challenging issue. This study evaluated the safety and efficacy of dual stent placement by using a low-profile stent system (LEO Baby) for the treatment of challenging distal intracranial aneurysms. MATERIALS AND METHODS We retrospectively reviewed patients in whom at least 1 LEO ...

BACKGROUND The transjugular intrahepatic portosystemic stent-shunt (TIPSS) builds a shortcut between the portal vein and a liver vein, and represents a sophisticated alternative to open surgery in the management of portal hypertension or its complications.

Fig. 1. (a) Oblique view from top of a self-expanding nitinol stent (length 28 mm, diameter 24 mm, Nitinol Devices & Components Inc., Fremont, CA, USA) containing a three leaflet polyurethane valve. Leaflets have a thickness of approximately 100—150 mm. The stent valves are produced in a dip coating technique (by Mecora GmbH, Aachen, Germany). (b) Low-profile polyurethane valved stent was folde...

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...
