Abstract
Aterosclerosis is chronic degenerative disease leading world death rates. One of the most affected areas are carotid arteries inwhich aterosclerotic plaque progression belongs to the most important causes of ischaemic stroke.
Duplex sonography is methodwidely available and safe enabeling realiable diagnostic of carotid arteries aterosclerosis. For stenosis quantification it is recommendedto apply multiparametric approach using criteria of direct and indirect sonographic diagnostic, moreover, recent researchfocuses on risk classification of aterosclerosis plaques (mainly detection of neovascularization, high lipid content, intraplaquehemorrhage, necrosis, ulceration, disruption of fibrin cup on plaque surface) and its sonogpraphic correlate which allow betterindividualization of invasive procedure indications, carotid endarterectomy and stenting inculded.
