PURPOSE Wingspan is the only FDA approved self-expanding stent for intracranial artery and known to have better delivery compared to balloon expandable stent. However, some delivery failure has been reported but incidence and mechanism of the failure have not been completely elucidated. We present the cause and mechanism of Wingspan deployment failure experienced in our Institute. MATERIALS A...

INTRODUCTION Dislodgement and embolization of the new generation of coronary stents before their deployment are rare but could constitute a very serious complication. CASE OUTLINE We report a case of a stent dislodgement into the left main coronary artery during the primary coronary intervention of infarct related left circumflex artery in a patient with acute myocardial infarction. The dislo...

Despite its low incidence, stent thrombosis (ST) is one of the most dreaded complications of percutaneous coronary intervention. Endeavor (Medtronics Europe SA) is a new zotarolimus-eluting stent (ZES) with a favorable safety profile that was reported in early and ongoing trials. However, few lethal stent thromboses related to this new drug eluting stent (DES) have been reported. We experienced...

Background: There have been reports on stent-related vascular erosions about patients with benign or malignant stenosis of the esophagus who received endoscopic stent insertion for palliative intention for oral intake. Case presentation: A 61-year-old woman with esophageal cancer located in the middle part of esophagus was treated with esophagectomy. Two years following the surgery, malignan...

The Ultimaster coronary stent system (Terumo Corporation, Tokyo, Japan) represents a new iteration in drug-eluting stent (DES) technology that has recently received the Conformité Européenne (CE) mark approval for clinical use. The Ultimaster is a thin-strut, cobalt chromium, biodegradable-polymer, sirolimus-eluting coronary stent. The high elasticity of the biodegradable-polymer (PDLLA-PCL) an...

BACKGROUND AND PURPOSE The endovascular treatment of aneurysms located at or distal to the circle of Willis and not amenable to coiling remains a challenge. We report our experience with flow-diversion treatment using low-profile braided stents as a stent monotherapy procedure for treating distally located very small or uncoilable aneurysms. MATERIALS AND METHODS We retrospectively reviewed o...

An essential feature of any endovascular device used to treat abdominal aortic aneurysms (AAAs) is the ability to accommodate any necessary changes after the delivery system has been introduced. The INCRAFT® AAA Stent Graft System (Cordis Corporation) was designed to solve the limitations of previous-generation endovascular devices, particularly with regard to versatility, accuracy, and real-ti...

OBJECT The aim of this study is to demonstrate the differences between the new Low-profile Visualized Intraluminal Support (LVIS Blue) stenting device and the Flow Redirection Endoluminal Device (FRED) using a series of bench-top evaluations and optical coherence tomography (OCT) images in a cadaveric preparation of the basilar artery. METHODS The first part of the evaluation was bench-top mi...
