PEREIRA RECIO, Héctor. Current state of the Doppler ultrasound in the vertebral arteries . AMC [online]. 2008, vol.12, n.3, pp. 0-0. ISSN 1025-0255.

The Doppler ultrasound is the most utilized image method in the carotids and vertebral study therefore offers a non-invasive evaluation of these vessels. Nevertheless, it has been paid little attention to the surgical procedures in the vertebral arteries and because of its anatomical localization are difficult to explore by echography, what reduces the interest to evaluate it in many patients, but its utility has been demonstrated in offering direct and indirect evidences of abnormalities in the circulation of these arteries including distal lesions to the segment that is explored and proximal as ostial stenosis or in the subclavian and brachiocephalic arteries, among others. Just like in the carotids there is no uniformity yet interpretating and carrying out the exam, which depends in great measure for lack of standardized exam protocols and the same ones may be carried out for a properly trained personnel. In this article a review of the current state of the Doppler ultrasound in the vertebral arteries, its indications, protocol of exam and the employed diagnostic criteria is done
