Predictive Value of Neovascularization Within Asymptomatic Carotis Stenosis on CEUS

Atherosclerosis is a chronic, systemic and progressive disease affecting different arterial blood vessels in the body. Atherosclerotic lesions silently progress from small plaques to severe stenosis and may remain asymptomatic for years. Unstable plaques and stenosis (also called vulnerable plaques), however, are prone to rupture leading to myocardial infarction, or stroke. The proliferation of the small arteries that are distributed to the outer and middle coats of the larger blood vessels (vasa vasorum) and within the atherosclerotic plaques (neovascularization) are inherently linked with the atherosclerotic plaque development, plaque inflammation and vulnerability. By injecting ultrasound contrast agents (microbubbles) into the blood stream, it is possible to detect this microcirculation of the vessel wall and the neovascularization within the atherosclerotic plaque using a contrast-enhanced ultrasound (CEUS) imaging technique. Particularly, CEUS of the carotid artery has been introduced as a non-invasive technique to improve detection of carotid atherosclerosis and to evaluate the presence of carotid plaque neovascularization which has emerged as a new marker for plaque vulnerability. The project investigates the predictive value of the detection of carotid plaque neovascularization on CEUS imaging in patients with asymptomatic carotid artery stenosis regarding the progression of the carotid atherosclerotic lesion and future vascular events including myocardial infarction…
