Accuracy of ultrasound arteriography in symptomatic patients with carotid bruits and negative or equivocal noninvasive testing.

Twenty patients with cervical bruits and complete noninvasive workup--including Doppler ultrasonography, oculoplethysmography, and carotid phonoangiography--were further studied with ultrasound arteriography and contrast angiography. This unique group of patients who had cervical bruit and equivocal noninvasive testing results were found to have 14 abnormal angiograms. The Doppler ultrasound arteriography demonstrated 100% sensitivity and 66.7% specificity by patient, when compared to contrast angiography.
