In follow-up the echocolor Doppler study of the extracranial vessels is indicated for the assessment of the progression of the carotid plaque and for monitoring the patients already treated.
In medical patients, the ultrasound imaging allows to determine the change in the echogenicity and in the degree of stenosis of the carotid plaque.
The echocolor Doppler is the test of choice in the follow up of the cervical arterial dissections (a dynamic process: most dissections eventually resolve, about two thirds of occlusions recanalize and one third of resulting aneurysms decreases in size). In this pathology the ultrasound findings may change dramatically within days or hours.
In the patients already treated (carotid endarterectomy or carotid artery stenting) the ultrasound study is indicated to exclude restenosis, to assess the patency of the vessel treated and to exclude the development of new or contralateral lesions.
In this lesson, the indications of the ultrasound study of the extracranial vessels in the follow up of the medical or treated patients are presented.

Member of the Order of Physician of Bologna n° 6728
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.
