Investigation of the Hemodynamics of Coronary Arteries - Effect of Stenting
Cardiovascular diseases (CVD) are the leading cause of death in the world. According to the World Health Organization (WHO) 17.3 million people died from cardiovascular disease in 2008, representing 30% of all global deaths. The most common modality of treatment of occluded arteries is the use of …

The Safety and Cost-Effectiveness of Carotid Angioplasty and Stenting in Calgary
… To evaluate the safety and cost of carotid stenting in Calgary. Methods A cost-utility analysis from the perspective of the Canadian health care system was performed comparing stenting to endarterectomy using a decision analytic model. A prospective cohort study was done for trans cranial …

A study of nanostructured materials toward coronary artery stenting and DNA-based biosensing
… OF MISSOURI AT AUTHOR'S REQUEST.] Vascular stenting has emerged as a viable method for treating occluded arteries. Unfortunately, implanted stents are subject to re-obstruction triggered by host tissue. A plasma nanocoating (20-30 nm) has been investigated for its ability to improve patient …

PTA e stenting carotideo: valutazione morfologica ed evolutiva, a breve e medio termine
… delle complicanze correlate all’utilizzo dello stenting carotideo. Dopo la preparazione di un protocollo con definizione di tutti i fattori di rischio sono stati individuati i criteri di inclusione ed esclusione attraverso i quali arruolare i pazienti. Da Luglio 2004 a Marzo 2007 sono stati …

Identifying Patients for Carotid Artery Stenting : Feasibility of Acetazolamide - Challenged Dynamic CT Perfusion
To correlate quantitative cerebrovascular reserve calculated by acetazolamide - challenged CT perfusion with clinical symptoms in patients with high-grade (>70%) carotid stenosis and impaired cerebrovascular reserve who did not have evidence of embolic stroke. Thirty-seven patients diagnosed as …

A review of the incidence and management of complications following malignant oesophageal stenting
Background Stenting provides effective palliation of malignant dysphagia for irresectable tumours due to either local invasion, metastatic disease, or poor performance status. Immediate technical success rates are very high, with clinical improvement approaching 90% in most reported series. …

Health-related Quality of Life One Year After Coronary Angioplasty and/or Coronary Stenting
… coronary angioplasty (angioplasty) and coronary stenting (stenting) are common revascularization treatments for coronary artery disease. Advances in cardiovascular technology have resulted in noninvasive treatment strategies in order to decrease symptoms, improve myocardial oxygenation, and …

Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
Hyperperfusion syndrome can occur in patients with preprocedural cerebral hemodynamic impairment who candidate for carotid stent. We investigated whether preprocedural measurement of cerebrovascular reserve (CVR) by using CT perfusion (CTP) with acetazolamide (ACZ) challenge could identify patients …

A Retrospective Review of the Technical Success of Endoscopic Stenting for Malignant Gastric Outlet Obstruction
… 70 (61.4%) male, were referred for palliative stenting of malignant GOO; distal obstructive gastric cancer (74.6%) and obstructing pancreatic malignancies (14.9%) being the two most frequent indications. Median age was 63.5years (IQR: 53.25-70) with 48.2% having at least one comorbidity and …

When working towards an optimised Carotid stenting procedure does patient, procedural and pharmacological selection impact on outcome.
… stroke prevention in the form of carotid artery stenting has been performed in clinical trials since the beginning of the 1980’s. Improvements in the operative technique and pharmacology used during the procedure have reduced complication rates since stenting began. Long term follow up of the …

Utility of the Visible Heart® and Micro-CT Imaging to Optimize the Treatments of Bifurcation Stenting
… including human, and thus to perform bifurcation stenting in an in vitro setting. This allows for novel uses of multimodal imaging for assessing/testing previous, current and future clinical recommendations for bifurcation techniques, without risking a living patient. After performing such …

Genotype- versus phenotype-directed personalization of antiplatelet treatment in Koreans with coronary artery disease undergoing coronary stenting
We evaluated the effectiveness of genotype- versus phenotype-directed individualization for use of P2Y12 inhibitors to decrease high on-treatment of platelet reactivity (HOPR). Sixty-five patients undergoing percutaneous coronary intervention for non-ST elevation acute coronary syndromes were …

A study on the short-term cognitive outcome of percutaneous transluminal coronary angioplasty with intra-coronary stenting
… angioplasty with intra-coronary stenting. Participants were assessed cognitively using specific neuropsychological tests used to measure performance in the seven cognitive domains. Forty people took part in the study, with twenty of them making up the stented group, and twenty of …

Transformer-Based Prediction of Coronary Artery Lumen Expansion Post Angioplasty Using Optical Coherence Tomography
… expand allows cardiologists to pursue pre-stenting calcium lesion modification strategies that help avoid dangerous complications of improper stenting. This work introduces a pipeline for post-stenting lumen area prediction from pre-stenting optical coherence tomography (OCT) images. This …

The compounding effects of obesity on the development of Intimal Hyperplasia following vascular intervention : a histopathological analysis
… both balloon angioplasty and endovascular stenting in the Zucker rat, a model that allows interpretation of the role of obesity as well as progressive glucose intolerance and hyperinsulimaemia. Lean and obese Zucker fatty rats and Zucker diabetic fatty rat (ZDF) were subjected to balloon …

Finite Element Analysis of a Novel Design for a Non-Migrating Biliary Stent
Biliary stenting is most frequently caused by an interruption in the ability to drain bile into the duodenum. This obstructive jaundice is commonly a result of a stricture from a tumor located at the pancreas’s head, peri-ampulary area, bile duct, or gall bladder. Jaundice can also occur from …

Resistance to Apoptosis in Smooth Muscle Cells and Stent-Induced Stenosis in Coronary and Peripheral Arteries
… States. Treatment often involves angioplasty and stenting. In 30-50% of angioplasty cases, success is limited by re-narrowing (restenosis) of the artery. Stenting offers the advantage of a slightly lower restenosis rate. However, this rate is still significant. Studies aimed at further …

Distant hemodynamic impact of local geometric alterations in the arterial tree
… manipulations such as angioplasty or stenting. We proposed that local vascular interventions might cause previously unforeseen effects elsewhere in the arterial tree. As an example of these interactions, manipulation of one branch of a bifurcation might adversely affect the …
