Fig.2 An endoscopic retrograde cholangiopancreatography (ERCP) cannula was used to puncture the mesh wall of the covered self-expandable metal stent (SEMS). A guidewire was then passed through the mesh wall and the opposite wall of the metal stent. Fig.1 A covered self-expandable metal stent (SEMS) used for endoscopic ultrasoundguided hepaticogastrostomy (EUS-HGS) had nearly migrated into the p...
INTRODUCTION We report a case of an emergency high-risk patient with a pararenal aortic aneurysm. REPORT Our patient had a pararenal aneurysm with two components: a wide-neck saccular aneurysm below the left renal artery and a fusiform aneurysm. A self-expandable aortic stent was deployed covering both renal arteries, the saccular aneurysm was embolised with microcoils and a bifurcated aortic...
OBJECTIVE To evaluate the safety and effectiveness of a 20-mm diameter dual-design expandable colorectal stent for malignant colorectal obstruction. MATERIALS AND METHODS The study series included 34 patients with malignant colorectal obstruction who underwent implantation of a 20-mm dual-design expandable colorectal stent in our department between March 2009 and June 2010. The 20-mm dual-des...
OBJECTIVE To evaluate the use of balloon-expandable metallic stents in the treatment of children with tracheomalacia and bronchomalacia in whom conventional therapy has failed. DESIGN Retrospective case series. SETTING Tertiary pediatric otolaryngology and cardiothoracic surgery referral center. PATIENTS Six patients were identified as having undergone bronchoscopic placement of metallic ...
BACKGROUND AND PURPOSE Endovascular treatment of wide-necked aneurysms remains a therapeutic challenge. We conducted this study to evaluate the angiographic results and clinical outcome of patients treated with stent-assisted coiling by using a recently available self-expandable intracranial stent. METHODS A retrospective review of all patients treated with self-expandable stent-assisted coil...
CONTEXT To demonstrate an EUS-guided biliary drainage in patient with gastrointestinal tract modified surgically. CASE REPORT An EUS guided access to the left intra hepatic duct, followed by an antegrade passage of a partially self-expandable metal stent that was removed by using an enteroscope, in one patient with hepatico-jejunal anastomosis. There were no early or delayed complications and...
The primary goal in the treatment of malignant obstruction is the relief of jaundice. Although operative biliary bypass is a reliable method of palliation, nonoperative palliation may be desirable in selected patients. We report our experience with forty-eight self expandable metallic biliary endoprostheses (Wallstent) percutaneously placed in 35 patients with irresectable malignant biliary obs...
OBJECTIVE To assess the therapeutic outcome after endovascular repair of iliac arterial lesions (IALs) using a self-expandable Nitinol stent graft system. METHODS Between July 2006 and March 2013, 16 patients (13 males, mean age: 68 years) with a self-expandable Nitinol stent graft. A total of 19 lesions were treated: nine true aneurysms, two anastomotic aneurysms, two dissections, one arteri...
BACKGROUND The self-expandable COMPLETE™ stent (Medtronic) has greater elasticity, allowing it to regain its shape after the compression force reduces, and has higher trackability, thus is easier to maneuver through tortuous vessels, whereas the balloon-expandable SCUBA™ stent (Medtronic) has higher radial stiffness and can afford more accurate placement without geographic miss, which is import...
