Active clinical trials for "Carotid Artery Diseases"

This study will be carried out prospectively on patients who applied to the cardiovascular surgery polyclinic and the carotid-vertebral artery doppler ultrasound due to the vascular problem. All patients will fill "Balance Disorder Scan Survey" and "Vertigo-Dizziness Imbalance Questionnaire-SS". Patients who score 1 and more are directed to the ear nose throat polyclinic and detailed differential diagnosis. Those who score 0 will be in control group.

This study aims to evaluate the use of R-One in the peripheral vasculature.

To determine the factors associated with progression of sub-clinical atherosclerosis and to evaluate the associations between the progression of sub-clinical atherosclerosis and the development of clinically manifest atherosclerosis.

Diabetes is a risk factor for carotid atherosclerotic whose progression is associated with an increased risk of vascular events. Investigators assessed prospectively by arterial duplex ultrasonography the progression of carotid atherosclerosis in a cohort of people with diabetes to assess the importance of progression and to analyze the impact of this progression on vascular events. The main hypothesis is that people with carotid atherosclerosis progression are at higher risk of vascular events than those without any progression.

The goal of this study is to evaluate the incidence of post procedure DW-MRI lesions (relative to baseline) and debris captured in the ENROUTE Transcarotid NPS inline filter during a transcarotid stenting procedure.

To examine the relationships among psychosocial factors and carotid atherosclerosis, myocardial ischemia, arrhythmias, and thrombosis.

To investigate hemostatic variables in relation to cardiovascular risk in the Framingham Offspring Study cohort.

The investigators hypothesized that circulating endothelium-derived microparticle (EMP) may be a useful surrogate marker of atherosclerosis and future episode of cerebrovascular events. Peripheral blood is drawn at the time of carotid ultrasound examination. Circulating EMPs are counted using flow-cytometry. The correlation among circulating EMP, ultrasound findings, and atherosclerotic risk factors are determined by multiple stepwise regression analysis. The prevalence of cerebrovascular events is also determined during 3-year follow-up period.

The purposes of this study is to 1) Provide additional information that the commercially available Abbott Vascular Carotid Stent Systems and Embolic Protection Systems can be used successfully by a wide range of physicians under commercial use conditions. 2) Provide an ongoing post-market surveillance mechanism for documentation of clinical outcomes and for possible extension of the Centers for Medicare and Medicaid Services (CMS) coverage to a broader group of patients.

The investigators use MRI and/or CT to evaluate the extent, as well as, the structure, composition, and functional aspects of atherosclerotic plaques in human carotid and femoral arteries in patients scheduled to undergo an endarterectomy of the aforementioned vascular beds as part of their routine clinical care.
