Objective: We formulated a simulator system for catheter intervention training by developing a sliding table and an electrically controlled camera-holding C-arm and combining them with the silicone vessel model EndoVascular Evaluator (EVE). We performed simulation of mechanical thrombectomy using this system and evaluated its usability for simulation training. Methods: After three experts in ne...

BACKGROUND AND PURPOSE The current report details our initial periprocedural experience with Wingspan (Boston Scientific/Target), the first self-expanding stent system designed for the treatment of intracranial atheromatous disease. METHODS All patients undergoing angioplasty and stenting with the Gateway balloon-Wingspan stent system were prospectively tracked. RESULTS During a 9-month per...

BACKGROUND In Brazil, despite the recommendations of the Brazilian Society of Hemodynamics and Interventional Cardiology, the National Health System has not yet approved the use of drug-eluting stents. In percutaneous coronary interventions performed in the public and part of the private health care system, bare metal stents are used as the only option. Therefore, new information on bare metal ...

Endoscopic ultrasound (EUS)-guided drainage is evolving and no standardized technique for it has been established yet. Availability of dedicated devices and accessories also are lacking. Anderloni et al. described a new technique of stent deployment named Intra Channel Stent Release Technique (ICSRT) in EUS-guided drainage [1], which is summarized as follows: deployment of the proximal part of ...

conclusions due to more sophisticated diagnostic tools and surgical approaches, mortality and morbidity of blunt aortic injuries were significantly reduced over the years compared to thoracic endovascular aortic repair and or over two different time periods. objectives the aim of the present study was to retrospectively evaluate the mortality and morbidity with either treatment option. therefor...

Medical implants and other biomaterials are used by millions of individuals all over the globe to restore lost bodily functions due injury or illness. Many these fail after a short time have difficulties, despite fact that they play important roles in keeping person's life safe increasing quality their lives. It is lack biocompatibility has proven be biggest downfall biomaterials. Investments t...

BACKGROUND AND PURPOSE One of the limitations of carotid artery angioplasty is the potential for embolic stroke. Our purpose was to assess whether the force of a self-expanding stent alone is usually sufficient to dilate severely stenotic atherosclerotic plaques without the deliberate use of an angioplasty balloon. If so, the procedural stroke risk might be reduced. METHODS Over a 30-month pe...

The first aim of this study was to evaluate the biocompatibility and degradation as well as potential clinical use of a new biodegradable PLGA (copolymer of L-lactide and glycolide acid) urethral stent with a braided mesh configuration. The second and at the same time, the main objective of this study was to develop a new drug-eluting biodegradable urethral stent. The biocompatibility profile o...

Endoscopic ultrasound (EUS)-guided hepaticogastrostomy with a fully covered metal stent is an option for malignant biliary obstruction after a failed endoscopic retrograde cholangiopancreatography (ERCP) [1–3]; however, migration of the stent can be a fatal complication [3, 4]. We report a case in which a migrated stent was successful reset using a foreign body forceps. A 73-year-old woman deve...

background the most important surgical complications of renal transplantation are stenosis and obstruction of anastomosis of the ureter to the bladder. hence, routine use of ureteral stents to prevent such complications seems logical; however, the optimal time to remove the ureteral stent is still controversial. objectives the purpose of this study was to compare the benefits and complications ...
