Filter by:The study objective is to evaluate real world usage of the ENROUTE Transcarotid Stent when used with the ENROUTE Transcarotid Neuroprotection System in patients at standard risk for adverse events from carotid endarterectomy
This is a randomized controlled study to assess the effect of atorvastatin and omega 3 combination therapy compared with atorvastatin and ezetimibe combination therapy in Korean T2DM patients with asymptomatic atherosclerosis.
This is a randomized controlled study to assess the effect of choline fenofibrate compared with policosanol in Korean T2DM patients with asymptomatic atherosclerosis.
SSPC includes degree of Stenosis, Symptoms, Plaque stability and Compensation of the cerebral blood flow. SSPC, a comprehensive evaluation system on carotid artery stenosis, is established and advocated in this trial in order to make assessment on risk of carotid revascularization preoperatively and prediction of cerebral events postoperatively.
This clinical imaging substudy will use the small molecule translocator protein (TSPO) ligand, Fludeoxyglucose(18F)-labeled DPA-714, to compare neuroinflammation in individuals with high or low grade asymptomatic carotid artery stenosis (aCAD) who are participating in the separate Neuroinflammation in Asymptomatic Carotid Artery Disease study lead by Dr. Ron Lazar (IRB-300007806). The positron emission tomography (PET) tracer [18F]DPA-714 binds to the 18 kDa translocator protein (TSPO, also known as the peripheral benzodiazepine receptor) in the mitochondria of activated microglia/macrophages and provides a non-invasive measure of neuroinflammation.
There are 10.3 million cases of stroke registered in the world every year; 63% of them lead to death. According to World Health Organization, stroke is one of the most important risk factors of death and early disability. Carotid artery surgery is a gold standard of hemodynamically significant carotid artery disease treatment. According to some trials, carotid artery surgery decreases the 2-years mortality. The most important part of carotid artery surgery is a temporary absence of blood flow in the carotid artery. The duration of this period is a crucial characteristic of this type of surgery. The absence of blood flow leads to brain ischemia which is the risk factor of postoperative neurocognitive disorders such as emergence delirium, postoperative delirium and postoperative cognitive dysfunction. Some surgical and non-surgical methods for brain protection were evaluated. According to recent data, there is no evidence of effective pharmacological protective methods that can decrease brain damage during carotid artery surgery. Nevertheless, some trials demonstrated that using lithium-based medications for patients with a stroke can reduce the volume of the stroke. Therefore, the investigators want to check the hypothesis that using lithium-based medication in the preoperative period can reduce brain damage during carotid artery surgery. The objectives of this trial: 1. To determine if Lithium carbonate is superior to placebo for the occurrence of emergence delirium, agitation, postoperative delirium and postoperative cognitive dysfunction. 2. To determine if Lithium carbonate is non-inferior to placebo for the occurrence of a new arrhythmia, leukocytosis, acute kidney injury, seizure disorders, diarrhea, nausea, and vomit.
Carotid endarterectomy (CEA) and carotid stenting (CAS) are often performed for subgroups of patients for whom procedural benefit has not been established in randomised trials and despite evidence of serious procedural risk. In some places, the COVID-19 pandemic has made it difficult or impossible to perform CEA and CAS in time. This study aims to measure the rate of ipsilateral stroke and other complications in individuals with symptomatic carotid stenosis, whom for any reason are managed using current best medical intervention alone. The investigators expect at least 50% lowering of the ipsilateral stroke rate compared to that seen with medical intervention alone in past randomised trials.
Digital Variance Angiography (DVA) is a new tool in medical imaging with a proven image quality reserve (1, 2). Previous studies have demonstrated the quality reserve of DVA in angiographic studies (1, 2), which allowed us to reduce contrast media use by 50% in carotid artery angiographic studies without affecting the image quality (3). CAS is an alternative treatment option for carotid artery revascularization in selected patient groups. Similar to most of the minimally invasive endovascular interventions, CAS also carries the risk of contrast-induced acute kidney injury, which is considered to be an independent predictor of 30-day major adverse events (4). The aim of this study is to apply DVA in patients undergoing carotid artery stenting (CAS) and utilize this technique to reduce contrast dose during the interventions, without affecting the intraprocedural radiation dose and the clinical outcome of the procedures. Investigators believe that the reduction in contrast media use and the associated image quality with the technique of DVA imaging can be incorporated into the everyday clinical practice, and will play an important role in improving the rate of contrast-induced acute kidney injury.
The CARUSO trial aims at investigating the efficacy of evolocumab in promoting carotid plaque morphological stabilization and regression as compared to traditional lipid lowering therapy (LLT). Primary end-point of the study is the superiority of evolocumab on top of ongoing LLT versus ongoing LLT in carotid plaque morphological stabilization and regression at 6 and 12 months, respectively. Secondary end-points are: LDL-Cholesterol (LDL-C) absolute and percentage changes in the two groups at 12 month follow-up, and adverse cerebrovascular and cardiac events at 12 and 24 months
Carotid artery disease is a main cause of ischemic stroke and vascular dementia, and a highly prevalent disease. There is uncertainty about the optimal management of patients with serendipitously or systematically detected asymptomatic carotid artery disease, due to the paucity of information on the predictive features of serious vascular events. While percent diameter stenosis is currently the accepted standard to decide about local interventions (carotid artery stenting or endarterectomy), international guidelines also recommend the evaluation of qualitative features of carotid artery disease as a guide to treatment. There is, however, no agreement on which qualitative features are best predictors of events. Furthermore, a role for metabolic plaque profile, local mechanical and hemorheologic factors in triggering microembolization and silent ischemic events has been proposed from experimental studies. This inadequate knowledge leads to a poor ability to identify patients at higher risk and to an unwarranted dispersion of medical resources, lack of standardization in diagnostic methods, and the use of expensive and resource-consuming techniques. Against this background, the investigators aim at: 1. Prospectively identifying the best predictors of (silent and overt) ischemic stroke and vascular dementia in patients with asymptomatic subcritical carotid artery disease, by identifying the non-invasive diagnostic features of the "vulnerable carotid plaque" as a possible guide for optimal - local and systemic - treatment. 2. Transferring new ultrasound techniques possibly improving risk prediction to the clinical field 3. Assess whether "smart", low-cost diagnostic methods, such as ultrasound-based evaluations integrating established and advanced techniques, may yield at least the same level of prospective information as more expensive and less cost-effective techniques.
