Carotid artery disease: natural history, diagnosis, and therapy
1Integrated Cardiovascular Therapeutics, Woodbury, New York.
Insights
Stroke is a major risk from carotid artery disease. Diagnosis relies on imaging like ultrasound and MRI, guiding treatments from medication to surgery or endovascular procedures.
Area of Science:
- Neurology
- Vascular Surgery
- Radiology
Background:
- Stroke is a significant complication of atherosclerotic cerebrovascular disease.
- Extracranial carotid occlusive disease contributes to a substantial portion of stroke events.
- Understanding carotid artery disease is crucial for stroke prevention.
Purpose of the Study:
- To outline the diagnostic and therapeutic strategies for extracranial carotid occlusive disease.
- To emphasize the role of objective testing in managing carotid artery disease.
- To review current treatment options for patients with carotid stenosis.
Main Methods:
- Review of diagnostic modalities including carotid duplex ultrasonography and magnetic resonance arteriography.
- Evaluation of therapeutic options based on symptom status and degree of stenosis.
- Discussion of the declining role of contrast arteriography.
Main Results:
- Objective testing is foundational for therapeutic decision-making in carotid artery disease.
- Treatment strategies are tailored to patient symptoms and stenosis severity.
- Multiple therapeutic avenues exist, including medical management, surgery, and endovascular interventions.
Conclusions:
- Carotid duplex ultrasonography and magnetic resonance arteriography are key diagnostic tools.
- Treatment decisions for carotid artery disease are guided by objective findings and clinical presentation.
- Therapeutic options range from antiplatelet therapy and risk factor modification to carotid endarterectomy and endovascular therapy.
Abstract:
Stroke remains a major complication of atherosclerotic cerebrovascular disease, with extracranial carotid occlusive disease accounting for nearly one-third of all events. Although historical symptoms and physical examination findings are important, objective testing with carotid duplex ultrasonography and magnetic resonance arteriography represent the foundation for therapeutic decision making. Contrast arteriography is playing a decreasing role in the evaluation of patients with carotid artery disease. Options for therapy, based on the presence or absence of symptoms and degree of stenosis, include antiplatelet therapy with cardiovascular risk factor modification, carotid endarterectomy, and more recently, endovascular therapy.
