Duplex US of the External Carotid Artery

Abstract: The ratio between the systolic peak velocities of the internal and common carotid arteries (vpICA/vpCCA), vpICA and grey-scale imaging measurement are generally used to evaluate internal carotid stenosis against known flow criteria in order to differentiate non-significant from significant stenosis. The same criteria are also used for evaluating the external carotid artery (ECA). Our data on 707 normal or stenotic ECA nevertheless showed that the systolic peak velocity of the normal ECA (vpECA) and its ratio t… Show more

“…To our knowledge, only one other study also compared the mean PSV of ECAs with different degrees of stenosis. Using DSA as the reference modality, Päivänsalo et al found the mean PSV of ECAs with 50% to 99% ECA stenosis to be roughly 182 cm/s, 7 which is significantly less than our mean PSV of 294 cm/s. A possible explanation for this could be that our carotid ultrasound exams were performed nearly 15 years after theirs, and significant improvements in ultrasonography have occurred since then.…”

“…Different cutoff velocities were selected to be analyzed based on velocities used in prior literature for 50% to 99% ECA stenosis. 7,[16][17][18] Two-bytwo contingency tables were created to calculate sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of each cutoff velocity compared with CTA. A receiver operating characteristic (ROC) curve was also created using the examined cutoff velocities, and the area under the curve is calculated to assess the diagnostic performance.…”

“…Interestingly, in our study, the mean ECA velocity was actually lower at 1 month, which may be an artifactual decrease related to the change in flow through the bulb and ICA. 19 It could also be due to architectural changes at the ECA after stent placement allowing improved flows (e.g., plaque compression and shifting). Regardless, the decreased velocities would certainly suggest no immediate detrimental effects of stent coverage.…”

“…2015 Abril; 28(nº especial):e1-e64 Para avaliar a estenose da ACE, além da elevação da VPS, alguns autores consideram que a relação entre a VPS da carótida externa e da carótida comum maior do que 2,0 (duas vezes) geralmente se associa com estenose superior a 50% 126 . Ascer e cols.…”
