Correlation of high-resolution, B-mode and continuous-wave Doppler sonography with arteriography in the diagnosis of carotid stenosis.

Abstract: One hundred thirty-one carotid bifurcations in 73 symptomatic patients were prospectively studied with high-resolution, B-mode sonography (HRS) and continuous-wave Doppler ultrasound (CWD). Twenty-three bifurcations were studied because of asymptomatic bruits, 30 for transient ischemic attacks, and 36 for focal or nonfocal symptoms or signs suggesting occlusive disease. The remaining 42 bifurcations were asymptomatic, with symptoms or signs confined to the contralateral bifurcation. Findings in the common, ext… Show more

“…Doppler findings were not utilized in this assessment due to recognized limitations in detection of non-occlusive plaque. 15 Stenosis and Occlusion -Obstructive lesions were classified based on percent of projected original lumen diameter as < 50%, > 50% but < 70%, > 70% stenosis, and occlusion. The maximal stenotic lesion detected in each arterial segment (common, external, or internal carotid artery) was tabulated for sonography (combined HRS and CWD), IV-DSA and standard arteriography.…”

“…A 10 MHz broadband transducer was utilized because state-of-the art vascular imagers utilize transducers in this frequency range. 15 Application of the technique developed for characterization in vivo will require methods for the compensation of effects of intervening tissue and tracking of motion of the vessel wall (e.g., coupling of quantitative ultrasonic characterization with real-time two-dimensional imaging). Nevertheless, we have been able to make substantial progress toward the development of a real-time system for quantitative myocardial imaging that incorporates techniques potentially applicable to vascular imaging after appropriate modification.…”

“…Both right and left common carotid arteries were scanned longitudinally to visualize the intimamedia complex on the far wall of the artery. The intima-media thickness was defined as the average of three distances randomly selected between 10 and 30 mm proximal to the bifurcation measured on the far wall between the leading edge of the intimal line and the leading edge of medial line [14]. The investigator carried out the procedure and the results were revised by another independent experienced radiologist.…”

“…The method used was a single-color whole-blood flow-cytometric assay as described previously [5,14] A GP Ib-MoAb (murine MoAb to CD42, Coulter Immunology) was used as a pan platelet marker to assure the purity of the platelet gate. Forward and sideward light scatters were set at a logarithmic increase.…”
