What is echocolordoppler of the supra-aortic trunks (carotids)?

By Cristiano Antonino On Dec 19, 2022

Echocolordoppler of the supra-aortic trunks, also known as the carotid or epiaortic vessels, is a noninvasive diagnostic examination dedicated to the carotid and vertebral arteries, i.e., those arteries whose function is to carry blood to the brain

It is an ultrasound enriched with visual and acoustic (color-doppler) values to monitor the arterial circulation directed toward the brain, to evaluate the blood vessels and the blood flow within them, and to diagnose the possible presence of changes in the vessel walls.

What is the purpose of supra-aortic trunk echocolordoppler?

With supra-aortic trunks echocolordoppler, it is possible to establish, study or rule out the presence of plaques in the vessels, which can lead to the presence of stenosis, i.e., points where the artery, reduced in caliber, allows less blood to pass through.

This condition, by reducing the supply of oxygen to the brain, is particularly dangerous as it can promote the onset of permanent ischemia, i.e., ICTUS or a transient ischemic attack (TIA).

Thanks to the examination, it is possible to identify the site of stenosis, quantify the percentage of narrowing of the vessel, the alteration on blood flow, and, thanks to the evaluation of the vessel’s inner wall, the degree of risk of the onset of ischemic-type cerebrovascular disease even in patients who do not have stenosis.

In short, therefore, the diagnostic test is the best method for assessing the risk of cardiovascular system disease in both symptomatic and non-symptomatic subjects.

When is supra-aortic trunk echocolordoppler performed?

Supra-aortic trunks echocolordoppler, abbreviated TSA, may be requested by a physician to screen a patient following a stroke or transient cerebral ischemia, to diagnose an aneurysm, or to rule out the presence of venous thrombosis.

In addition, it can be recommended for screening patients with cardiovascular risk factors, i.e., subjects with hypertension, diabetes, hypercholesterolemia, dyslipidemia, obesity, etc.

In addition, the examination is recommended for screening of:

patients with a family history of cerebral or cardiac ischemic events;
smokers;
patients about to undergo major vascular surgery;
patients undergoing radiation therapy of the neck.

How is the supra-aortic trunk echocolordoppler performed?

The examination consists of a simple and absolutely noninvasive method.

In fact, it involves no preparation for the patient and has no contraindications.

It is performed like any ultrasound and lasts an average of 20 minutes.

At the end of the echocolordoppler examination of the sovaortic trunks, should the presence of stenosis or the risk of cerebrovascular disease be identified, it will be possible to make therapeutic decisions aimed at:

correct risk factors through careful planning of prophylaxis suitable for slowing the progression of the disease;
establish appropriate treatment.

In the case of the presence of stenosing or occlusive pathology affecting the supra-aortic trunks, the physician may prescribe the patient either pharmacological therapy or surgical therapy, which consists of carotid endarterectomy, aimed at removing the plaque attached to the inner surface of the vessel.

*This is indicative information; therefore, it is necessary to contact the facility where the examination is performed to obtain specific information on the preparation procedure.
