Predictive haemodynamics of the human carotid artery
… parametrically defined geometry of the human carotid artery bifurcation to better understand the relationship between a range of parameters and the associated haemodynamics and to devise strategies to provide guidance for clinical interventions and to assist in the design of stents and grafts. …

Computational analysis on stent geometries in carotid artery
… invasive technique for treating the narrowed artery or stenosis in carotid artery to restore blood to the brain. However, the restenosis process is usually observed after a few weeks of carotid stenting due to abnormal progression of atherosclerosis and thrombosis. Many studies reported that …

Vitamin D, ADAM-12 and Carotid Artery Disease
Risk of hypertension, peripheral artery disease, myocardial infarction and development of human atherosclerosis has been linked to vitamin D deficiency. Atheromatous cytokines, including IL-6, TNF-α and epidermal growth factor receptor (EGFR) family growth factors are released at the site of …

Carotid collar : a device for auscultory detection of carotid artery stenosis
The carotid collar is a hardware device designed to aid in detecting carotid artery stenosis, a disease that increases the risk of stroke. This device consists of three electronic stethoscopes that record heart and carotid artery sounds and an electrocardiograph. A software application, ccrec, was …

Effects of Chronic Selective Serotonin Reuptake Inhibitor Use on Carotid Artery Atherosclerosis
… and depression independently increased coronary artery atherosclerosis; however effects on carotid artery atherosclerosis, a precursor to ischemic stroke, are unknown. Whether SSRI use affects risk factors for stroke and atherosclerosis is also unclear as results from clinical trials and …

Relation between carotid artery FDG uptake and cardiovascular risk in asymptomatic adults
We investigated the relation between carotid artery FDG uptake and cardiovascular risk based on the Framingham risk score (FRS), and evaluated the possible role of FDG uptake in terms of risk stratification of asymptomatic adults. We evaluated 290 adults who underwent FDG PET/CT as part of general …

Identifying Patients for Carotid Artery Stenting : Feasibility of Acetazolamide - Challenged Dynamic CT Perfusion
… 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 unilateral severe carotid stenosis and 10 age-matched normal controls underwent acetazolamide - challenged CT …

Detection Method of Subclinical Atherosclerosis of the Carotid Artery with a Hemodynamics Modeling Approach
… it is based on The Framingham Risk Score and carotid intima media thickness, therefore an engineering detection model based on quantifiable data is needed. Laminar and turbulent flow, dictated by Reynolds number and relative roughness, was modeled through the carotid artery bifurcation to …

Mixed Dementia Induced by Right Common Carotid Artery Occlusion in an Alzheimer Mouse Model
… (Tg-) were subjected to permanent right common carotid artery occlusion (rCCAO). The Morris water maze and object recognition tests were performed 6-8 weeks after the operation; the mice were then sacrificed. We evaluated cell death by histological studies and quantified the amount of amyloid …

A cellular automaton – based system for the identification of topological features of carotid artery plaques
… of a plaque in one or both of the internal carotid arteries poses a serious threat to the lives of those in whom it occurs. This thesis describes a technique designed to detect level of occlusion and provide topological information about such plaques. In order to negate the cost of …

Employing Fluid Structure Interaction Analyses to Reveal Insights in Atherosclerotic Progression in the Carotid Artery
… response of an anatomically realistic carotid artery using 1-way coupled Fluid Structure Interaction (FSI). We computationally analyzed blood flow in 4 stages of carotid artery stenoses (0%, 30%, 60% and 80%) at 3 levels of orientation of the stenosis with bulk flow direction. We …

Development of a Vascularized Carotid Artery Plaque Phantom for the Investigation of Novel Ultrasound-Based Technologies
… (IPN) in advanced lesions in the carotid artery can be visualized using contrast-enhanced ultrasound (CEUS) technology, and its accurate quantification could provide a powerful tool for the detection of vulnerable plaque. This project was undertaken to develop a model of …

Design of a wearable ultrasound Doppler sensor to monitor blood flow in the common carotid artery
… ultrasonic beams directed at the common carotid artery. The Doppler frequency shift generated by the moving blood is then processed to reconstruct the centerline velocity of the artery as well as to provide an estimate of the velocity profile and other physiological parameters. The …

Carotid artery intima-media thickness measurement in subjects with type 2 diabetes in Cape Town, South Africa
… have less atherosclerosis as measured by Carotid Intima Media Thickness (CIMT) than non-black South Africans.

Predictability of Cardiovascular Disease Event Rates by Common Carotid Artery Intima-Media Thickness in the Atherosclerosis Risk in Communties (ARIC) Study
<p><strong>Background:</strong> Carotid artery intima media thickness (IMT) is a non-invasive reliable predictor of the extent and severity of CVD. There is difficulty acquiring all measurements for validated three-site carotid IMT. More accessible one-site common carotid artery (CCA) IMT has not …

Occlusion of the Internal Carotid Artery of Horses: Evaluation of a Technique Designed to Prevent Epistaxis Caused by Guttural Pouch Mycosis
… adult horses, the origin of the left internal carotid artery was isolated via a modified hyovertebrotomy approach. Normograde blood flow was occluded by placement of a tourniquet on the artery near its origin. Lumenal access was gained through placement of a distally directed introducer sheath …

Examining endothelial function in humans in vivo: improving guidelines and exploring novel measures
… introduced in 1992, which relies on brachial artery vasodilation after a hyperaemic stimulus (e.g. after occlusion of a pneumatic cuff), and the susceptibility of the FMD measurement to variability. In Chapter 2 we sought for factors that might help to improve the reproducibility of the FMD …
