Insights
Carotid artery stenosis affects 9% of adults over 60, causing stroke risk. Treatment options include medication and revascularization, with surgery reducing stroke risk by 17%.
Area of Science:
- Vascular Surgery
- Neurology
- Diagnostic Imaging
Context:
- Atherosclerotic carotid artery stenosis affects approximately 9% of individuals over 60.
- This condition can lead to transient or permanent cerebral ischemia, including fatal strokes.
- Carotid artery stenosis accounts for 20-25% of all strokes.
Purpose:
- To assess the prevalence and risks associated with carotid artery stenosis.
- To evaluate the effectiveness of current treatment strategies for carotid artery stenosis.
- To compare surgical endarterectomy with percutaneous angioplasty and stenting.
Summary:
- Ultrasound with Doppler is effective for assessing carotid artery stenosis.
- Asymptomatic stenosis treated with aspirin has a 6-11% stroke risk over 5 years.
- Symptomatic stenosis carries a significantly higher risk of TIA or stroke recurrence (30-45%).
- Surgical treatment reduces stroke risk by 17%, with endarterectomy being the gold standard, though angioplasty with stenting is an alternative.
Impact:
- Highlights the significant stroke risk posed by carotid artery stenosis.
- Emphasizes the importance of risk factor management and revascularization.
- Suggests percutaneous angioplasty with stenting as a viable alternative to surgical endarterectomy.
Abstract:
Atherosclerotic stenosis of carotid arteries is present in approximately 9% of patients above 60 years of age. The stenosis may be silent or may cause cerebral ischaemia--transient or permanent, including severe stroke leading to death. It is estimated that 20-25% of all strokes is caused by carotid artery stenosis in their extracranial course. Ultrasound technique with Doppler recording is an efficient method of carotid arteries stenoses assessment. Asymptomatic carotid artery stenosis treated with acetylsalicylic acid 325 mg/day bears 6-11% risk of stroke in 5 years follow-up. The risk of cerebral ischaemia is significantly higher in persons with symptomatic stenoses. The risk of TIA or stroke recurrence reaches 30-45%. The treatment of carotid arteries stenoses comprises risk factors management and revascularisation procedures. Surgical treatment decreases the risk of stroke by 17%. Surgical endarterectomy perceived as the gold standard of interventional treatment may be efficiently replaced with percutaneous angioplasty with concomitant intravascular stent implantation.
