Endoscopic treatment of a bronchial restenosis previously treated by insertion of a partially covered self-expandable metallic stent (SEMS) can be difficult. Classically, after recanalization of the bronchus, the stent is removed and replaced by a more adapted one. We report on two cases of proximal bronchial restenosis treated by insertion of an additional stent inside the lumen of the previou...

OBJECTIVES This study was designed to study the behavior of a stent deployed inside human stenotic aortic valves. BACKGROUND Endovascular valved stent (VS) implantation is a promising new therapy for patients with severe calcific aortic stenosis (AS). The precise characteristics of stent deployment in humans have been poorly studied so far. METHODS Thirty-five patients with severe AS were i...

With the successes achieved in treatment of gastric cancer , problem combined neoadjuvant therapy for stenosing tumors remains unresolved . To find optimal method we carried out analysis modern domestic and foreign literature The standard methods are implantation a self - expandable stent argon-plasma coagulation nasointestinal feeding tube formation gastroenteroanastomoses gastro / enterostomy...

Purpose — In-stenting restenosis is one of the major complications after stenting. Clinical trials of various stent designs have reported different restenosis rates. However, quantitative correlation between stent features and restenosis statistics is scant. In this work, it is hypothesized that stress concentrations on arterial wall caused artery injury, which initiates restenosis. The goal is...

Fatigue resistance of nitinol stents implanted in femoropopliteal arteries is a critical issue because their harsh biomechanical environment. Limb flexions due to daily walk expose the and, subsequently, large cyclic deformations, which may lead fatigue failure smart self-expandable stents. For first time, this paper utilised up-to-date measurements walk-induced motion human artery investigate ...

Conservative treatment for esophageal perforations can cause problems related to both nutrition and wound healing in pediatric patients due its long duration. This case report presents a 14-month-old female patient who underwent endoscopic balloon dilatation stricture. The had been operated on atresia the neonatal period. Eight hours after discharge, was hospitalized again perforation. Although...

A 55-year-old man with dysphagia due to an unresectable distal esophageal adenocarcinoma underwent placement of a 15-cm partially covered self-expandable metal stent (SEMS), diameter 18mm (Ultraflex; Boston Scientific, Natick, Massachusetts, USA). After 3 months, he presented with recurrent dysphagia. At endoscopy, the meshes of the SEMS had broken, leading to collapse of the SEMS and obstructi...

Popliteal artery pseudoaneurysm is a rare injury occurring in total knee replacement surgeries. The symptoms are usually pain and swelling on the affected side which prompts immediate investigations. Surgical endovascular interventions both available options for intervention with covered stents being preferred choice. In this study, we report case of 72-year-old female diagnosed right popliteal...

Background/Aims: Self-expandable metal stents (SEMSs) are effective palliation for malignant gastric outlet obstruction (GOO). Double-layered (Comvi) SEMSs were developed to overcome limitations of uncovered or covered SEMSs. The aims of study were to evaluate efficacy and safety of Comvi stent compared with uncovered and covered stents, and to determine factors related to stent patency. Method...
