Key result
High-resolution real-time sonography demonstrated 86% accuracy for detecting flow-reducing lesions (≥50% stenosis) and 89% for non-flow-reducing lesions compared to angiography.
Why the study?
Does high-resolution real-time sonography accurately detect plaque and estimate stenoses compared to angiography in patients with carotid atherosclerosis?
Population
50 consecutive patients (97 carotid bifurcations)
Comparison

May support sonography screening before angiography in carotid disease; leaves open prospective validation in larger cohorts.

Does high-resolution real-time sonography accurately detect plaque and estimate stenoses compared to angiography in patients with carotid atherosclerosis?
High-resolution real-time sonography is highly accurate for assessing minimal carotid disease but less reliable for complete vessel occlusion, making it a useful screening tool before angiography.
Wolverson et al. (1983) conducted a cross-sectional in Carotid atherosclerosis (n=50). High-resolution real-time sonography vs. Angiography was evaluated on Accuracy for detecting flow-reducing lesions (≥50% stenosis or complete occlusion). High-resolution real-time sonography demonstrated 86% accuracy for detecting flow-reducing lesions (≥50% stenosis) and 89% for non-flow-reducing lesions compared to angiography.
