Insights
Symptomatic carotid artery stenosis significantly increases stroke risk. Both carotid endarterectomy (CEA) and carotid artery stenting (CAS) are recommended for high-grade symptomatic lesions, offering superior stroke prevention compared to medical therapy alone.
Area of Science:
- Vascular Surgery
- Neurology
- Cardiovascular Medicine
Background:
- Extracranial carotid artery stenosis is a major cause of stroke, a leading cause of death.
- Symptomatic carotid stenosis necessitates urgent evaluation and treatment.
- Medical therapy for carotid stenosis is evolving.
Purpose of the Study:
- To review the evidence-based modern management of symptomatic carotid stenosis.
- To discuss the role of revascularization procedures in stroke prevention.
Main Methods:
- Review of landmark clinical trials comparing surgical intervention with medical therapy.
- Analysis of modern investigations evaluating carotid artery stenting (CAS) against carotid endarterectomy (CEA).
Main Results:
- Carotid endarterectomy (CEA) has demonstrated superiority over medical therapy for stroke prevention in symptomatic lesions.
- Carotid artery stenting (CAS) has been shown to be non-inferior to CEA.
- Combined data support a class I recommendation for CEA or CAS in high-grade symptomatic carotid stenosis.
Conclusions:
- Modern management emphasizes revascularization (CEA or CAS) for high-grade symptomatic carotid stenosis.
- Treatment decisions should consider the acceptable risk of perioperative events.
- Evidence supports a shift towards interventional procedures for optimal stroke prevention.
Abstract:
Extracranial carotid artery stenosis accounts for up to 12 % of stroke, the third leading cause of death in industrialized nations. Carotid stenoses leading to transient or permanent neurologic or retinal symptoms within the preceding 6 months are deemed symptomatic and require prompt noninvasive evaluation and treatment. Preventive medical therapy is standard for symptomatic carotid stenosis and continues to evolve. Landmark trials have proven carotid endarterectomy (CEA) superior to medical therapy for stroke prevention in symptomatic lesions. Modern investigations have proven carotid artery stenting (CAS) non-inferior to CEA, and the strength of the combined data has led to a class I recommendation for CEA or CAS in patients with high grade symptomatic carotid stenosis, provided the risk of perioperative events is acceptable. Evidence-based modern management of symptomatic carotid stenosis is reviewed here.
