Giant-cell arteritis is associated with a higher risk of aortic aneurysm and aortic dissection formation. We present a women with aortic dissection type B treated with a stent graft and bare-metal stent implantation. After the stent deployment we noticed aortic rupture, which was successfully treated with implantation of an additional stent graft. This report highlights the difficulty of endova...
OBJECTIVE The aim of the study is to evaluate midterm results with regard to false-lumen status of a combined vascular and endovascular approach for the treatment of acute type A aortic dissection. METHODS We performed ascending/hemiarch replacement during hypothermic circulatory arrest with additional open implantation of the Djumbodis Dissection System (non-self-expanding bare metal stent) ...
We report a case of very late bare-metal stent restenosis, in which assessment by two intracoronary imaging techniques (intravascular ultrasound and optical coherence tomography) revealed the underlying mechanism (neoatherosclerosis) and facilitated percutaneous treatment (direct bare-metal stent-in-stent). We also take the opportunity to briefly describe the advantages and limitations of both ...
BACKGROUND AND STUDY AIMS Membrane-covered self-expandable metal stents are effective in preventing tumor ingrowth and stent obstruction in patients with inoperable esophageal cancer, but migration of stents continues to be a major problem. We therefore constructed a modified covered self-expandable esophageal metal stent capable of being fixed using a silk thread. The stent was studied prospec...
BACKGROUND Sirolimus-eluting stents markedly reduce the risk of restenosis compared with bare metal stents. However, it is not known whether there are differences in effectiveness between bare metal and sirolimus-eluting stents in patients with total coronary occlusions. METHODS AND RESULTS In a prospective, randomized, single-blind, 2-center trial, we enrolled 200 patients with total coronar...
CONTEXT Insertion of a self-expandable metal stent is still controversial for treatment of benign common bile duct stenosis but can be a valuable alternative to surgical treatment. OBJECTIVE Aim of our study was to analyze the efficacy of covered and uncovered self-expandable metal stent in patients with chronic pancreatitis and common bile duct stenosis. MATERIAL AND METHODS Twenty patient...
PURPOSE Irreversible electroporation (IRE) uses short duration, high-voltage electrical pulses to induce cell death via nanoscale defects resulting from altered transmembrane potential. The technique is gaining interest for ablations in unresectable pancreatic and hepatobiliary cancer. Metal stents are often used for palliative biliary drainage in these patients, but are currently seen as an ab...
Together with biliary drainage, which is an appropriate procedure for unresectable biliary cancer, biliary stent placement is used to improve symptoms associated with jaundice. Owing to investigations comparing percutaneous transhepatic biliary drainage (PTBD), surgical drainage, and endoscopic drainage, many types of stents are now available that can be placed endoscopically. The stents used a...
