The echocolor Doppler of the carotid plaque is performed to have information about its degree of stenosis and its composition/surface.
The degree of stenosis is the most correlated clinical event: the greater is the stenosis, the greater is the risk of TIA/stroke and the benefit of surgery. Therefore, particular care should be used to evaluate the percentage of stenosis.
The main parameters that should be used in diagnosing and grading internal carotid artery stenosis are the peak systolic velocity and the presence of plaque on grayscale and/or color Doppler/duplex US images.
Although CDU cannot precisely define the percentage of stenosis diameter, a range of stenosis diameters may be estimated.
In this lesson the methodology of the echocolor Doppler study of the degree of carotid stenosis is presented.

I am a specialist in Medical Angiology and I am based in Bologna, Italy. Until 2008 (voluntary resignation) I worked at Maggiore Hospital in Bologna as "Dirigente Medico" in the Department of Internal Medicine and as Angiologist in the Angiology Unit with a position of "Alta Professionalità" in "Vascular Ecography and Angiology".
I am currently working in Bologna as an independent professional in the areas of angiology and vascular diagnostics.
I have been a speaker at national and international courses/congress and I have taught duplex ultrasound method in GIUV and SIUMB courses at the Maggiore Hospital, Bologna and courses of echocolor Doppler of extracranial and intracranial arteries at the Stroke Unit of S. Maria Nuova Hospital, Reggio Emilia.
