Colour-duplex echography in atherosclerotic carotid artery disease

Area of Science:

• Vascular Surgery
• Diagnostic Imaging
• Cardiovascular Disease

Background:

• Atherosclerotic lesions in the carotid artery pose a significant risk.
• Accurate assessment of these lesions is crucial for surgical decision-making.
• Color duplex echography has emerged as a key diagnostic tool.

Purpose of the Study:

• To review the principles and diagnostic value of color duplex echography for carotid artery atherosclerotic lesions.
• To evaluate the efficacy of duplex-based surgical decisions in a clinical setting.
• To assess the correlation between preoperative duplex data and operative findings.

Main Methods:

• Review of the history, principles, technique, and diagnostic value of color duplex echography.
• A trial comparing preoperative color duplex data with operative findings in 36 carotid endarterectomy cases.
• Analysis of stenosis degree, lesion geometry, and plaque composition.

Main Results:

• Surgical decisions based on color duplex echography were deemed perfectly justified in 97% of cases (35 out of 36).
• Excellent correlation was observed between duplex-determined stenosis (33 perfect, 2 fair, 1 poor), geometry (27 perfect, 5 fair, 4 poor), and plaque composition (20 perfect, 10 fair, 6 poor) and surgical findings.
• Color duplex echography proved invaluable in managing carotid artery atherosclerotic disease.

Conclusions:

• Color duplex echography is an indispensable tool for the management of carotid artery atherosclerotic disease.
• Carotid artery surgery can often be performed effectively following a "duplex only" investigation.
• Continuous quality monitoring and improvement of echography laboratories are essential.
