Ex-vivo 3D assessment of carotid stenosis with ultrasound
… of arterial structure and composition in the carotid vessel wall. It has been shown that the progression of the disease can be monitored by tracking changes in the carotid intima-media thickness (IMT). Non-invasive peripheral vascular ultrasound (U/S) of the carotid artery is a non-invasive, …

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 …

Coronary Artery Calcium and Incident Stroke in the Multi-Ethnic Study of Atherosclerosis (MESA) Cohort
… to predict the presence of significant/overt carotid stenosis in an asymptomatic cohort.11 Despite the relationship between carotid stenosis and risk of future stroke, the prognostic value of CAC to predict incident stroke remains unclear. The MESA cohort provides a unique opportunity to study …

Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
… 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 at risk for hyperperfusion after CS. For 12 patients with …

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. …

Development of a Passive Immunization Strategy Against Atherosclerosis
… affects the lumen, inducing various degrees of stenosis. The rupture of the atherosclerotic plaques, followed by local thrombosis, is the underlying cause of myocardial infarction and stroke, which claim millions of lives every year worldwide. Oxidized LDL and the immune system play very …

Radiomics and Machine Learning in the Prediction of Cardiovascular Disease
Carotid atherosclerosis is a major risk factor for ischaemic stroke which is a leading cause of death worldwide. For stroke survivors, 1 in 4 will have another stroke within five years. Carotid CT angiography (CTA) is commonly performed following an ischaemic stroke or transient ischemic attack to …

Carotid Atherosclerosis: Why Some Patients are Symptomatic and Others Not?
… and mortality in the United States. OVD of the carotid arteries results in stroke or transient ischemic attacks. A significant number of strokes are caused by carotid artery atherosclerosis. Atherosclerosis, commonly referred to as "hardening of the arteries," is a disease where there is build …

Improved qualification of vascular abnormalities in contrast enhanced magnetic resonance angiographic images
… stroke is the percentage of the narrowing in the carotid arteries, which lead blood from the heart to the brain, which currently is quantified manually. This project is in collaboration with Blackpool Victoria Hospital and Christies Hospital in Manchester. The aim of this project is to develop …

Longterm peripheral baroreflex and chemoreflex function after bilateral eversion carotid endarterectomy
Introduction The “eversion” technique for carotid endarterectomy (e-CEA), that involves the transection of the internal carotid artery at the carotid bulb and its eversion over the atherosclerotic plaque, has been associated with an increased risk of postoperative hypertension possibly due to a …

Der Einfluss von Plaquemorphologie und anderen prädiktiven Faktoren auf das Auftreten von Mikroembolien während der Stentgeschützten Perkutanen Angioplastie der Karotiden (SPAC)
Hintergrund: Zerebrale mikroembolische Läsionen sind die häufigsten Komplikationen der Stentgeschützten Perkutanen Angioplastie der Karotiden (SPAC). Diese gelten als Folge thrombembolischer Abscheidungen aus der Karotisplaque während der Intervention. Plaquezusammensetzung und morphologie spielen …
