Computerized Assessment of Carotid Plaque Echogenicity before Stenting

Area of Science:

• Vascular Surgery
• Neurology
• Medical Imaging

Background:

• Carotid atherosclerotic plaques are a risk factor for procedural strokes.
• Accurate identification of high-risk plaques is crucial for stroke prevention.

Purpose of the Study:

• To evaluate transcutaneous ultrasound (US) for identifying carotid atherosclerotic plaques associated with a high risk of procedural stroke.
• To assess the utility of gray-scale value (GSV) in characterizing plaque echomorphology.

Main Methods:

• Retrospective analysis of plaque echomorphology using gray-scale value (GSV).
• Comparison of transcutaneous US and intravascular US for plaque characterization.
• Computerized assessment of plaque echogenicity.

Main Results:

• Transcutaneous US and intravascular US showed similar abilities in characterizing atherosclerotic plaques.
• The case with embolic complication exhibited the lowest GSV among the studied cases.
• Plaque echogenicity, assessed by GSV, correlated with stroke risk.

Conclusions:

• Pre-procedural transcutaneous US, with computerized assessment of plaque echogenicity (GSV), can predict plaques linked to high risk of distal embolization.
• This method may aid in preventing procedural strokes.
