Clinical Scorecard: Ultrasound Evaluation of Atherosclerotic Plaques: Advancements in Technique and Anatomical Understanding

At a Glance

Key Highlights

• Carotid plaques are associated with significant 10-year cardiovascular event risk.

• Plaque ulceration, surface irregularity, composition, and thickness are associated with vulnerability or clinical risk.

• Three-dimensional ultrasound detects carotid plaque ulcerations more effectively than two-dimensional ultrasound.

• Maximum carotid plaque thickness predicts stroke risk independently of stenosis severity.

• European vascular guidelines emphasize incorporating plaque morphology into decision-making for asymptomatic patients.

Guideline-Based Recommendations

Diagnosis

• Duplex ultrasound can assess stenosis and characterize carotid plaque morphology.

Management

• European vascular guidelines emphasize incorporating plaque morphological characteristics into decision-making for asymptomatic carotid disease.

Monitoring & Follow-up

• Plaque burden and unstable or rapidly progressive plaques are important considerations when estimating patient risk.

Risks

• Plaque rupture can precipitate atherothrombosis and its complications.

Patient & Prescribing Data

The review addresses atherosclerotic plaques, particularly carotid plaques, in asymptomatic and symptomatic populations.

It does not provide medication-specific prescribing recommendations.

Clinical Best Practices

• Ultrasound can characterize plaque location, size, internal structure, surface, and echogenicity.

• Plaque morphology can complement stenosis severity and clinical variables in cardiovascular risk stratification.

• Emerging techniques and multiparametric scores require further standardization and prospective validation before routine clinical use.
