- Define and list non-atheromatous pathologies that can affect the cervical vessels. - Present the diagnostic signs and vascular US findings with case images (US and angioCT scan). - List and explain the main differential diagnoses.
The most frequent carotid pathology is atherosclerotic.
The US is a good method to evaluate atheromatous plaques and obstructive lesions.
it is also effective in the diagnosis of other less frequent,
but not less important,
tumor or congenital etiologies.
Findings and procedure details
1- Definition of the non-atheromatous disease of the carotid vessels (NADCA): It is all carotid pathology that is not of atheromatous cause.
Atheromatous plaques and their complications,
such as stenoses or occlusions,
are excluded.It is important to know,
if the lesion is primary of the carotid space,
if it is vascular and if itis adjacent or intrinsic to the Internal Carotid Artery (ICA) 6 . 2- Etiologies :The NADCA etiologies involve a series of not so frequent entities such as congenital...
Although atherosclerotic carotid disease is the most frequent in our environment with a high associated morbidity and mortality,
the radiologist must know the other not so frequent causes of carotid disease.
Clinical suspicion coupled with the use of imaging methods such as ultrasound,
allow a timely diagnosis of these etiologies that,
like carotid atherosclerosis,
have important associated morbidity.
