First-line treatments
Carotid duplex surveillance
Regular ultrasound monitoring of carotid artery morphology and stenosis progression to guide timing of intervention in asymptomatic patients.
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Antiplatelet and statin therapy
Aspirin or clopidogrel combined with statins to reduce plaque progression, inflammation, and thrombotic risk in carotid artery disease.
Additional treatment options
Cardiovascular risk factor modification
Smoking cessation, blood pressure control, diabetes management, and weight reduction to address underlying causes of carotid artery abnormalities.
lifestyleCarotid endarterectomy
Open surgical removal of atherosclerotic plaque from the carotid artery to restore normal lumen diameter and prevent stroke in significant stenosis.
surgicalCarotid artery stenting
Transcatheter placement of a stent to mechanically open narrowed carotid segments, particularly in patients at high surgical risk.
