Background: Atherosclerosis, characterized by lipid accumulation and plaque formation within arterial walls, is a major cause of cardiovascular diseases (CVD) including coronary artery disease (CAD), cerebrovascular disease, and peripheral artery disease (PAD). The extra cranial carotid arteries are critical sites for atherosclerotic plaque development, potentially leading to ischemic strokes and other cerebrovascular events.
Objective: This review explores the role of ultrasound in evaluating extra cranial carotid arteries and examines the correlation between ultrasound findings and atherosclerosis risk factors, emphasizing its utility in risk stratification, guiding therapeutic decisions, and monitoring disease progression.
Methods: A comprehensive literature search was conducted using PubMed, MEDLINE, and Google Scholar. Studies relevant to ultrasound evaluation of extra cranial carotid arteries and the correlation with atherosclerosis risk factors were selected. Key search terms included "carotid artery ultrasound," "atherosclerosis," "risk factors," "intima-media thickness," and "carotid plaque."
Conclusion: Ultrasound, particularly Doppler ultrasound, is a non-invasive, safe, and reliable method for assessing carotid atherosclerosis. It provides real-time visualization of arterial structures and hemodynamics, enabling detailed evaluation of intima-media thickness, plaque characteristics, and luminal stenosis. Early detection and monitoring of atherosclerotic changes in the carotid arteries facilitate timely interventions, reducing the risk of cerebrovascular events. Correlating ultrasound findings with atherosclerosis risk factors is crucial for improving patient outcomes.
