Carotid artery stenting (CAS) is currently the standard of care for carotid atherosclerotic lesions. The goal of CAS is to provide support for the arterial wall and attempt to restore normal blood flow; however, placement of a stent causes significant alterations to the treated artery’s vascular morphology and hemodynamics. The presence of stagnant or recirculation zones around the stent struts...

migration in the treatment of anastomotic leak Toshniwal J et al. report about the use of the OTSC System to anchor a fully covered self-expandable metal stent to prevent stent migration. The patient underwent distal esophagectomy with gastric pull-up. The stent was placed to a postoperative anastomotic leak in the esophagus. However, the stent partially migrated into the stomach. The stent was...

BACKGROUND AND PURPOSE The Acclino is a laser-cut closed-cell microstent composed of nitinol. It was developed for stent-assisted coiling of wide-neck intracranial aneurysms. The key feature of the stent is its deployability via low-profile microcatheters with an inner diameter of 0.0165 inch, which are also suited for coil deployment. The objective of this study was to evaluate the safety and ...

OBJECTIVES The purpose of this study was to assess whether the newer stent delivery systems provide a stented lumen cross-sectional area (CSA) that is equal to the delivery balloon nominal dimensions. BACKGROUND First generation stents were often not adequately expanded with their delivery system and frequently required higher pressure or a larger balloon after deployment. Newer stents were d...

Four patients underwent angioplasty and stenting of medically refractory symptomatic intracranial atherosclerosis with the new Wingspan stent system. In all 4 patients, CT angiography (CTA) showed an abnormality within the stented segment that was suggestive of nonocclusive in-stent thrombus. However, subsequent conventional angiography findings were typical for in-stent restenosis. The CTA ima...

The use of self expandable metallic stents (SEMS) in the palliation of dysphagia due to malignant esophageal stenosis is a gold standard. Covered stents are used in all cases with overt air-digestive fistula or high potential for fistula development. The procedure is associated with a low incidence of procedure-related complications. We present a case with a major accident which developed durin...

sheared guidewire following failed endoscopic ultrasound-guided pancreatic duct drainage A 50-year-old man with a retained sheared guidewire in the main pancreatic duct and pancreatic parenchyma was referred for recurrent pancreatitis. He had previously undergone a pancreaticoduodenectomy for pancreatic hemangioma and was experiencing recurrent pancreatitis due to pancreaticojejunostomy strictu...

BACKGROUND The aim of this study was to assess the safety and the efficacy of the novel sirolimus-eluting Prolim® stent with a biodegradable polymer in the all-comers population. METHODS We prospectively enrolled all patients with stable coronary artery disease or acute coronary syndrome treated with Prolim® stent between January and December 2013 in two interventional cardiology centers in P...

BACKGROUND Prophylactic pancreatic stents after endoscopic retrograde cholangiopancreatography (ERCP) can help prevent post-ERCP pancreatitis. However most of the pancreatic stents need to be removed by another ERCP. The aim of this observational study was to investigate the feasibility and effectiveness of the modified pancreatic stent system for prevention of post-ERCP pancreatitis. METHODS...
