BACKGROUND Both primary angioplasty alone and angioplasty with a self-expanding stent have been compared in non-randomized concurrent clinical studies that suggest equivalent results. However, there is no randomized trial that has compared the two procedures in patients with symptomatic high grade intracranial stenosis. OBJECTIVE The primary aim of the randomized trial was to compare the clin...

The neologism ‘stent’ has irrevocably entered the English medical vocabulary as a noun as well as a verb. It allegedly dates back to the English dentists Charles T. Stent (1807–1885) and his sons Charles R. Stent (1845– 1901) and Arthur H. Stent (1859–1900) who used to support poorly aligned teeth with a special apparatus. Others have traced the word back to the 14th century. The first mention ...

The bare metal stent (BMS) used in the blood vessel caused the restenosis after the operation due to formation and proliferation of neointimal. Recently, as a method to overcome the problems of BMS, drug eluting stent (DES) is developed and being applied to human body which has drug reducing restenosis applied on the metal surface. DES has the advantage of greatly reducing the restenosis after ...

OBJECTIVE To evaluate the effect of temporary stent graft placement in the treatment of benign anastomotic biliary strictures. MATERIALS AND METHODS Nine patients, five women and four men, 22-64 years old (mean, 47.5 years), with chronic benign biliary anastomotic strictures, refractory to repeated balloon dilations, were treated by prolonged, temporary placement of stent-grafts. Four patient...

the patient was a 19 year-old woman with the diagnosis of resistant hypertension, although she was under treatment of three classes of anti-hypertensive drugs (beta blocker, angiotensin receptor blocker, diuretic) for more than one year. in physical examination there was only a significant difference between the systolic blood pressure of upper and lower extremities (200 vs. 120 mmhg), without ...

INTRODUCTION Primary infection of a bare metal stent is a rare condition, associated with significant morbidity and mortality. Definitive treatment includes stent removal and arterial reconstruction. REPORT This study details a common iliac stent infection after re-intervention for iliac stent occlusion, complicated by pseudoaneurysm formation and septic embolisation. Potential risk factors f...

Very late thrombosis in an implanted bare-metal stent is a very uncommon event outside the context of brachytherapy and few data about its pathophysiology are available. We performed an intravascular ultrasound study during primary angioplasty in five patients with very late bare-metal stent thrombosis and carried out a histological analysis of the material removed by manual thrombectomy. The m...

Recently, endoscopic ultrasound (EUS)guided biliary drainage has been introduced as an alternative method after failed endoscopic biliary drainage, particularly in patients with a pre-existing duodenal obstruction [1–3]. A longer self-expandable metal stent (SEMS) is usually used for EUS-guided hepaticogastrostomy (EUS-HGS) to prevent stent migration. However, re-intervention after EUS-HGS is c...

Self-expandable metal stents are often used to treat obstructive large bowel cancers. This study assessed the safety and efficacy of colonic stent insertion carried out in a district general hospital. Methods A retrospective review was carried out between 1 January 2007 and 28 February 2014 to identify patients who underwent stent insertion for malignant colorectal obstruction. Results Seventy-...

BACKGROUND The objective was to evaluate the role of risk factors and stent type for stent thrombosis (ST) using a large real world registry. METHODS AND RESULTS We evaluated all consecutive coronary stent implantations in Sweden from May 1, 2005, to June 30, 2007. All cases of ST, documented in the Swedish coronary angiography and angioplasty registry until September 21, 2008, were analyzed....
