AIM To assess the effect of polyglycolic acid (PGA) plus stent placement compared with stent placement alone in the prevention of post-endoscopic submucosal dissection (ESD) esophageal stricture in early-stage esophageal cancer (EC) patients. METHODS Seventy EC patients undergoing ESD were enrolled in this randomized, controlled study. Patients were allocated randomly at a 1:1 ratio into two ...

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 ...

BACKGROUND There are limited studies of stent thrombosis in the modern era of second-generation stents, high-pressure deployment, and current antithrombotic regimens. METHODS AND RESULTS Six recently completed coronary stent trials and associated nonrandomized registries that enrolled 6186 patients (6219 treated vessels) treated with >/=1 coronary stent followed by antiplatelet therapy with a...

Placement of a self-expanding metal stent (SEMS) is an effective method for palliation of a malignant biliary obstruction. However, metal stents can cause various complications, including stent migration. Distally migrated metal stents, particularly covered SEMS, can be removed successfully in most cases. Stent trimming using argon plasma coagulation may be helpful in difficult cases despite co...

a w a t t a c s t v k p s ne of the most dreaded complications after percutaneous oronary arterial angioplasty is stent thrombosis. This erious untoward event usually results in acute myocardial nfarction with high mortality. Stent thrombosis often ocurs early, within 30 days of implantation, in patients who eceive bare metal coronary arterial stents. However, paients undergoing drug-eluting st...

The purpose of the study was to compare the impacts of angiographically successful direct stent implantation and conventional stent implantation (stent implantation following predilatation) on long-term major cardiac events. The authors prospectively studied 40 patients who had successful direct stent implantation and 46 patients who had successful conventional stent implantation. The end-point...

Four patients underwent angioplasty and stenting of medically refractory symptomatic intracranial atherosclerosis with the new Wingspan stent system. In all 4 patients, CT angiography (CTA) showed an abnormality within the stented segment that was suggestive of nonocclusive in-stent thrombus. However, subsequent conventional angiography findings were typical for in-stent restenosis. The CTA ima...

The AXIOS stent (Boston Scientific, Marlborough, MA) is a novel lumen-apposing self-expandable metallic stent designed for enteric drainage of nonadherent lumens. Efficacy and safety of using the AXIOS stent for pancreatic fluid drainage have been consistently shown in several studies. Although it is less common with this novel stent, stent migration still may happen. We present a case of AXIOS...

INTRODUCTION There is debate on renal graft stenting during ureteroneocystostomy, patients with ureteral stents may encounter several complications such as encrustation, stent crustation which can lead to loss of kidney, and complications related to stent extraction: pain and UTI increasing related to cystoscopy for stent extraction accompanying excess expenses. This study designed to reduce co...
