BACKGROUND AND OBJECTIVES The aim of this study was to examine the anti-proliferative and anti-inflammatory effects of a stent coated with abciximab and alpha-lipoic acid (ALA) in a porcine coronary overstretch restenosis model. MATERIALS AND METHODS A total of 10 pigs were randomized into two groups (10 pigs, 10 coronaries in each group) in which the coronary arteries were stented with a dua...
BACKGROUND We compared the effectiveness of self-expanding metal stent alone vs. radioactive stent embedded with 125I seeds implantation insertion in patients of inoperable esophageal squamous cell cancer combined with malignant esophageal stenosis. METHODS We studied two groups of patients with stenosis attribute to inoperable esophageal squamous cell carcinoma. Group A had placed self-expan...
Endoscopic therapy by balloon dilation and placement of multiple large-bore plastic stents is the treatment of choice for benign biliary stricture. This approach is effective but it typically requires multiple endoscopic sessions given the short duration of stent patency. The endoscopic approach for treatment of bile leak involves the placement of a stent with or without biliary sphincterotomy....
Metal stents and, more recently, polymer-coated metal stents are used to stabilize dissections, eliminate vessel recoil, and guide remodeling after balloon angioplasty and other treatments for arterial disease. Bioresorbable polymeric stents are being developed to improve the biocompatibility and the drug reservoir capacity of metal stents, and to offer a transient alternative to the permanent ...
OBJECTIVES The purpose of this research was to determine the relative safety and efficacy of multiple (> or =2) overlapping Cypher sirolimus-eluting stents (SES) (Johnson & Johnson, New Brunswick, New Jersey). BACKGROUND Overlapping coronary stents are common. The periprocedural and late clinical and angiographic consequences of overlapped coronary stents are not clearly defined, particularly...
To determine the relation of intimal hyperplasia thickness to stent size in nonpolymeric paclitaxel-coated stents, intravascular ultrasound was performed after stent implantation and at 6 months. Similar to bare metal stents, this study demonstrated that intimal hyperplasia thickness is independent of stent size. There was no deleterious effect of the increased concentration associated with usi...
The development of stent has been a major achievement in treating obstructive coronary artery disease (OCAD). The main obstacle in the long term success of percutaneous coronary intervention (PCI) was the neo-intimal hyperplasia developed within the stent, which may leads to instent restenosis. The introduction of Drug-eluting stents (DES) shows steep decrease in angiographic restenosis when co...
BACKGROUND Treatment of patients with drug-eluting stent (DES) in-stent restenosis (ISR) is more challenging than that of patients with bare-metal stent ISR. However, the results of everolimus-eluting stents (EES) in these distinct scenarios remain unsettled. METHODS AND RESULTS A pooled analysis of the RIBS IV (Restenosis Intra-Stent of Drug-Eluting Stents: Paclitaxel-Eluting Balloon vs Ever...
Unfortunately, the original version of this article [1] contained an error. The correct paragraph can be found below: The calculation of number of patients was not correct. It was wrote the non-inferiority margin as 0.1 mm. But it was 0.19 mm in an original document. Non-inferiority margin in previous coronary intervention studies has been set between 0.1 ~ 0.2 mm. The 0.19 mm is not irrelevant...
INTRODUCTION Heart disease is the leading cause of death in the United States, with approximately 610,000 deaths every year [1]. Heart disease is often related to atherosclerosis, or plaque buildup in the artery walls. This buildup hardens and narrows the arteries, thereby obstructing blood flow and increasing risk for heart attack, stroke, or peripheral vascular disease. The common treatment f...
