Cholangitis prevention in endoscopic Klatskin tumor palliation: air cholangiography technique.
2009
INTRODUCTION: Endoscopic biliary drainage is the treatment of choice for inoperable hilar cholangiocarcinoma (so-called Klatskin tumor). Cholangitis is the main complication post-endoscopic retrograde cholangiopancreatography (ERCP) in Klatskin patients, specially when medium contrast is injected into biliary tree that could not be subsequently drained. Bacterial cholangitis is the principal cause of mortality in these patients. The aim of this study is to analyze cholangitis rate resulting from the use of air versus iodine contrast to obtain cholangiography during ERCP. METHODS: In 9 years, 188 inoperable Klatskin patients were recruited and divided into two groups: iodine (A) or air (B) c…
Management of Coronary Artery Perforation
2020
Coronary artery perforation (CAP) is a rare but potentially life-threatening complication of percutaneous coronary intervention (PCI), however if recognized and managed promptly, its adverse consequences can be minimized. Risk factors for CAP include the use of advanced PCI technique (such as atherectomy and chronic total occlusion interventions) and treatment of severely calcified lesions. There are 3 major types of CAP depending on location: (a) large vessel perforation, (b) distal vessel perforation, and (c) collateral perforation. Large vessel perforation is usually treated with implantation of a covered stent, whereas distal and collateral vessel perforations are usually treated with c…
Current role of the chimney technique in the treatment of complex abdominal aortic pathologies: A position paper from the PERICLES Registry investiga…
2020
Historically, chimney/snorkel endovascular aortic repair (Ch-EVAR) emerged as a rescue technique to revascularize and/or preserve inadvertently covered critical branch vessels during infrarenal aortic endografting. Next, in its evolutionary path, Ch-EVAR offered a viable treatment option for complex aortic repair, and particularly in situations where fenestrated/ branched EVAR was not a therapeutic option due to the lack of availability and/or anatomical constraints. In this context, this technique offered distinct advantages such as off-the-shelf availability, straightforward implantation techniques, and lower resource use-intensity enabling performance by a large number of operators manag…
Endoscopic Neurosurgery “Around the Corner” with a Rigid Endoscope. Technical Note
1999
Endoscopically "working around the corner" is presently restricted to the use of flexible endoscopes or an endoscope-assisted microneurosurgical (EAM) technique. In order to overcome the limitations of these solutions, endoscopic equipment and techniques were developed for "working around the corner" with rigid endoscopes. A steering insert with a 5 French working channel is capable of steering instruments around the corner by actively bending the guiding track and consecutively the instrument. A special fixation device enables strict axial rotation of the endoscope in the operating field. Endoscopic procedures "around the corner", including aqueductal stenting, pellucidotomy, third ventric…
Safety and efficacy of biodegradable polymer-coated thin strut sirolimus-eluting stent vs. durable polymer-coated everolimus-eluting stent in patient…
2018
Introduction The biodegradable polymer drug-eluting stents were developed to improve vascular healing. However, further data are needed to confirm the safety and efficacy of these stents in patients with acute myocardial infarction (AMI). Aim We sought to determine the 1-year clinical follow-up in patients with AMI treated with a thin strut biodegradable polymer-coated sirolimus-eluting stent (BP-SES) versus a durable coating everolimus-eluting stent (DP-EES). Material and methods We analyzed patients with AMI (STEMI and NSTEMI) treated with either a BP-SES (ALEX, Balton, Poland, n = 886) or DP-EES (XIENCE, Abbott, USA, n = 1054) with available 1-year clinical follow-up using propensity sco…
Hemosuccus pancreaticus--a rare cause of gastrointestinal bleeding: diagnosis and interventional radiological therapy.
2000
Hemorrhage from the pancreatic duct, i.e. hemosuccus pancreaticus (HP), is a rare cause of gastrointestinal bleeding. Pancreatic hemosuccus is usually due to the rupture of an aneurysm of a visceral artery, most likely the splenic artery, in chronic pancreatitis. Other causes of HP are rare. We present a case of HP in a female patient with no history but with positive findings of chronic calcifying pancreatitis upon ultrasonographic investigation, computed tomography scan, and endoscopic retrograde cholangiopancreatography. With detectable fresh blood in the descending duodenum, angiography of the celiac artery revealed an aneurysm of the splenic artery as the suspected cause of intermitten…
Endovascular Treatment of Spontaneous and Isolated Infrarenal Acute Aortic Syndrome with Unibody Aortic Stent-Grafts
2020
Abstract Introduction Spontaneous acute aortic syndrome (IAAS) is rarely localized in the infrarenal aorta. The endovascular approach is preferred over conventional open surgery with fewer complications. However, dedicated endovascular devices for IAAS treatment are unavailable. The aim was to report a large single-center experience using unibody stent-grafts to address IAAS. Methods From April 2016 to March 2019, a retrospective analysis of patients presenting spontaneous and isolated IAAS was performed. Patients addressed with the unibody stent-graft (AFX endovascular AAA system; Endologix Inc., Irvine, CA) were included in the study. Indications to IAAS treatment were persistent symptoms…
Drug eluting and bare metal stents in people with and without diabetes: Collaborative network meta-analysis
2008
Objective To compare the effectiveness and safety of three types of stents (sirolimus eluting, paclitaxel eluting, and bare metal) in people with and without diabetes mellitus. Design Collaborative network meta-analysis. Data sources Electronic databases (Medline, Embase, the Cochrane Central Register of Controlled Trials), relevant websites, reference lists, conference abstracts, reviews, book chapters, and proceedings of advisory panels for the US Food and Drug Administration. Manufacturers and trialists provided additional data. Review methods Network meta-analysis with a mixed treatment comparison method to combine direct within trial comparisons between stents with indirect evidence fr…
Endoscopic palliative management of esophageal and tracheal rupture
2014
The increasing number of patients requiring intensive care and airway support has led to a growing recognition that significant short- and long-term morbidity may be associated with the use of artificial airways; this is despite significant improvements in the materials used in laryngeal tubes, which aim to decrease the trauma associated with long-term intubation. We present the first case, to our knowledge,of huge, nontraumatic, esophageal perforation, widely communicating with the trachea, and which was treated successfully with double endoscopic stent placement.
Biodegradable polymer-coated thin strut sirolimus- -eluting stent versus durable polymer-coated everolimus-eluting stent in the diabetic population.
2021
Background: The number of patients with diabetes mellitus (DM) presenting with coronary artery disease is increasing and accounts for more than 30% of patients undergoing percutaneous coronary interventions (PCI). The biodegradable polymer drug-eluting stents were developed to improve vascular healing. It was sought herein, to determine 1-year clinical follow-up in patients with DM treated with the thin strut biodegradable polymer-coated sirolimus-eluting stent (BP-SES) versus durable coating everolimus-eluting stent (DP-EES). Methods: Patients were retrospectively analyzed with DM were treated with either a BP-SES (ALEX™, Balton, Poland, n = 670) or a DP-EES (XIENCE™, Abbott, USA, n = 884)…
