Insights
Carotid stenosis treatment aims to prevent ischemic stroke. Guidelines recommend carotid endarterectomy for symptomatic stenosis, with stenting as an alternative for high-risk patients.
Area of Science:
- Vascular Surgery
- Neurology
- Cardiology
Background:
- Carotid stenosis is a significant risk factor for ischemic stroke.
- Current guidelines recommend invasive treatment for specific patient groups.
- Optimal medical therapy is crucial for all patients with carotid artery disease.
Purpose of the Study:
- To outline current recommendations for invasive treatment of carotid stenosis.
- To discuss the role of carotid endarterectomy and stenting.
- To emphasize the importance of interdisciplinary decision-making and optimal medical therapy.
Main Methods:
- Review of contemporary guidelines and available evidence.
- Analysis of indications for intervention in symptomatic and asymptomatic patients.
- Consideration of carotid artery stenting as an alternative to endarterectomy.
Main Results:
- Carotid endarterectomy is recommended for symptomatic stenosis (50-99%).
- Intervention timing is crucial, ideally within 2-14 days post-event.
- Carotid artery stenting is a viable option for high-surgical-risk patients.
Conclusions:
- Invasive treatment decisions require careful consideration of stroke risk and patient factors.
- Interdisciplinary collaboration is essential for optimal patient management.
- Optimal medical therapy should be prioritized for all patients with carotid artery disease, regardless of intervention.
Abstract:
Invasive treatment of carotid stenosis is directed towards the prevention of ischemic stroke. Contemporary guidelines, based on the best available evidence, recommend carotid endarterectomy for symptomatic carotid stenosis of 50-99%. Revascularization should ideally be performed within 48 hours to 14 days following the index ischemic event. In asymptomatic patients, intervention is indicated in the presence of clinical or morphological markers associated with an increased risk of carotid stenosis-related stroke. Carotid artery stenting represents a complementary alternative to endarterectomy, particularly in patients at high surgical risk. Given that several recommendations are based on expert opinion rather than high-level evidence, interdisciplinary decision-making plays a crucial role. Patients with limited life expectancy should not undergo invasive treatment; all patients with carotid artery disease should receive optimal medical therapy.
