[Color coded duplex scanning examination of the carotid artery]
Abstract:
A recent developed ultrasound technology that combines the B-mode real time imaging, colour flow imaging and pulsed Doppler velocity measurements with spectral analysis was used for bilateral carotid artery examinations of 81 patients with suspicion of carotid stenosis. The results in 9 cases was compared with angiographic findings. This paper describes the basic principles of this method, the fundamental of the estimation of the lumen reduction. Authors present the advantages and limitations of this method and conclude that the colour coded duplex scanning sonography is an accurate noninvasive technique that suitable for detection of the extracranial carotid artery diseases. They emphasize that in all of 5 cases with amaurosis fugax significant homolateral stenosis was found in the communis or internal carotid artery.
