Why the study?
Does videodensitometric computer analysis of B-mode ultrasound images correlate with histological characteristics and symptomatology in patients with high-grade carotid stenosis?
Population
25 patients admitted for carotid endarterectomy for extracranial high-grade internal carotid artery…
Comparison
Quantitative ultrasonic tissue characterization… vs Histological examination of surgically removed…
Design
Cross-sectional
Key result
Videodensitometric analysis revealed that symptomatic patients had significantly lower mean gray levels in carotid plaques compared to asymptomatic patients (p=0.04), indicating more vulnerable, lipid-rich lesions.

May support noninvasive vulnerability assessment in carotid stenosis; hypothesis-generating and should not yet change practice.

Absolute Event Rate: 0.389% vs 0.565%
p-value: p=0.04
Videodensitometric analysis of carotid ultrasound images can distinguish symptomatic from asymptomatic plaques and correlates with histological fibrosis, offering a non-invasive method to identify vulnerable plaques.
Baroncini et al. (2006) conducted a cross-sectional in Extracranial high-grade internal carotid artery stenosis (n=25). Symptomatic carotid artery stenosis vs. Asymptomatic carotid artery stenosis was evaluated on Mean gray level (MGL) of carotid plaque (p=0.04). Videodensitometric analysis revealed that symptomatic patients had significantly lower mean gray levels in carotid plaques compared to asymptomatic patients (p=0.04), indicating more vulnerable, lipid-rich lesions.
