Active clinical trials for "Carotid Stenosis"

The purpose of this study is to determine the accuracy of a new non-invasive device, the Carotid Stenotic Scan (CSS), to check for stenosis of the internal carotid artery (ICA) as compared to a carotid duplex ultrasound study.

The objective of the research, is to examine the hypothesis, that the enzyme paraoxygenase 1 ( PON1) can influence carotid artery's atherosclerotic plaque content and stability, and its relation to plasma's enzyme concentration.

The results in carotid surgery are an indicator of the functioning of an academic surgical team, making it possible to evaluate and improve practices, as much among surgeons in training as among senior surgeons. The indications have evolved with the development of symptomatic stenosis surgery, and results analysis has allowed us to improve our practices. It would be of great use to have the statistics obtained in previous years to continue improving our practices.

Introduction: Taxinomisis trial is part of the Taxinomisis project. The concept of the Taxinomisis project is to stratify carotid artery disease relying on new modern data corresponding to contemporary patients based on information from longitudinal studies. Taxinomisis trial will validate this tool and adjust such stratification. Initial step of the project is characterization of symptomatic and asymptomatic carotid atherosclerotic plaque lesions, identification of risk and susceptibility factors through the exploitation of longitudinal cohort data and multiomics and disintegration of carotid artery disease phenotypes into endotypes through joint modeling of multipleomics data sets and systems medicine approaches. Finally such stratification model will be validated and adjusted in the Taxinomisis clinical trial.

Contrast-enhanced ultrasound(CEUS) of carotid artery plaque is a novel method that enabled direct visualization of neovessels in the vulnerable plaque. Plaque enhancement with CEUS showed correlation with the histologic density of neovessels within the carotid plaque and the previous cardiovascular events. Vulnerable plaques with a high risk of thromboembolic complications and rapid progression is associated with acute ischemic stroke. The prognostic value of vulnerable carotid artery plaque depicted with CEUS has not been fully investigated. The purpose of this study is to define prognostic value of plaque enhancement on carotid CEUS in acute stroke patients. Research question is; in acute ischemic stroke patients with ipsilateral carotid plaque as probable etiology of stroke, is the presence of carotid plaque enhancement on CEUS independent predictor of future stroke.

Establish and validate biomarkers which improve the predictive value of current risk stratification models for patients benefiting from carotid revascularization, outperform existing biomarkers, and reach clinical application standards.

The carotid arteries are blood vessels in the neck that supply blood to the brain. Carotid stenosis disease is defined as a narrowing of these arteries due to the build up of plaque. The plaque material can also break off and move into the brain. The resulting blockage of blood supply to a portion of the brain is what causes 80% of all strokes. One treatment option is to have surgery on the carotid artery and remove the plaque. This procedure is called a carotid endarterectomy (CEA). There is evidence that proves CEA reduces the risk of stroke. The objective of this research project is to determine who is most likely to benefit from CEA surgery.
