OBJECTIVES The aim of this study was to investigate the occurrence and the clinical impact of stent fractures after femoropopliteal stenting. BACKGROUND The development of femoral stent fractures has recently been described; however, there are no data about the frequency and the clinical relevance. METHODS A systematic X-ray screening for stent fractures was performed in 93 patients. In tot...

BACKGROUND Vessel remodeling is an important mechanism of late lumen loss after nonstent coronary interventions. However, its impact on in-stent restenosis has not been systematically investigated. METHODS AND RESULTS Serial volumetric intravascular ultrasound analyses (poststent and follow-up) were performed in 55 lesions treated with a balloon-expandable stent (ACS MultiLink) using standard...

This is a retrospective study to evaluate the prevention of complications of metallic stent placement in patients with unresectable advanced esophageal cancer. A total of 87 patients were treated with 4 types of metal stents in the esophagus over a period of 18 years. Stent placement was technically successful. The most common prior treatment was chemoradiotherapy. There were no significant dif...

OBJECTIVES The purpose of this prospective study was to evaluate the immediate results and the 6-month angiographic recurrent restenosis rate after balloon angioplasty for in-stent restenosis. BACKGROUND Despite excellent immediate and mid-term results, 20% to 30% of patients with coronary stent implantation will present an angiographic restenosis and may require additional treatment. The opt...

Stent fracture is an emerging complication of coronary stenting. Stent fractures were originally reported in the superficial femoral arteries but have since been reported in almost all vascular sites. They are the result of the complex interplay among stent design, the stented segment, plaque morphology, deployment technique, including forceful exaggerated motion in the atrioventricular groove ...

Compliance mismatch between stent graft and host artery may induce complications and blood flow disorders. However, few studies have been reported on stent graft compliance. This study aims to explore the deformation and compliance of stent graft in stented and unstented zones under three pressure ranges. Compliance of two stent grafts incorporated with polyurethane graft (nitinol-PU) and polye...

The article presents our experience of observing two different approaches for endoscopic retrograde drainage in patients with malignant pathology the pancreatobiliary zone, complicated by bile duct obstruction. In one case, case dysfunction installed uncovered stent as a result incrustation salts and/or tumor invasion, stent-to-stent restenting was performed. second if it impossible to pass gui...

BACKGROUND Stenting likely decreases the need for target-vessel revascularization procedures in diabetic patients compared with balloon angioplasty. However, the efficacy of stenting with platelet glycoprotein IIb/IIIa blockade has not yet been assessed in diabetics. METHODS AND RESULTS We analyzed the outcomes of 491 diabetic patients within the multicenter Evaluation of Platelet IIb/IIIa In...

uretero-pelvic junction obstruction (upjo) is a common congenital anomaly that may need pyeloplasty to prevent renal function deterioration. the purpose of this study was to describe a modified use of jj stent catheter in pyeloplasty for infant with upjo. a series of 12 children, between 3 and 10 months, underwent stenting open pyeloplasty. in each patient a 6 french foley catheter was placed w...

assisted extraction of proximally migrated biliary plastic stent Stent placement is widely indicated as treatment for biliary obstruction or compression [1]. However, migration is frequently observed, particularly when plastic stents are used for benign strictures. Distally migrated stents are usually spontaneously eliminated and do not require any intervention. Proximal migration often require...
