When should you intervene with carotid stenosis?
Risk is greatest within 48 hours of symptom onset; patients should have urgent evaluation by a vascular surgeon for consideration of carotid endarterectomy (CEA). Patients with 50% to 69% stenosis might benefit from urgent surgical intervention depending on clinical features and associated comorbidity.
What is asymptomatic carotid endarterectomy?
For most people with a narrowing of the carotid artery which is not causing symptoms a surgical operation to remove the narrowing carries a risk and has little benefit. Carotid stenosis is a narrowing of a major artery in the neck taking blood to the brain.
What is significant carotid artery stenosis?
Carotid artery stenosis is a narrowing of the large arteries on either side of the neck. These arteries carry blood to the head, face, and brain. This narrowing is usually the result of a build-up of plaque within the arteries, a condition called atherosclerosis.
Does an endarterectomy resolve carotid stenosis?
Research shows that if the paient has NOT had a stroke or a TIA, carotid endarterectomy is generally helpful to reduce stroke risk if the narrowing is 70% or greater. If the patient has suffered a stroke or TIA, carotid endarterectomy may be helpful if the stenosis is over 50%.
What are treatments for carotid stenosis?
Several medications are prescribed in the treatment of carotid artery stenosis, although none of these provide a cure for the condition. Anticoagulant medications or blood thinners such as warfarin are used to prevent the formation of a clot. Anti-platelet medications such as aspirin and clopidogrel are also used to prevent stroke.
What percent of carotid artery blockage requires surgery?
Asymptomatic and symptomatic carotid artery disease with blockage of 50 percent to 69 percent (with results from diagnostic tests indicating blockage closer to 69 percent) may require surgical treatment.
How serious is a mild narrowing of the carotid artery?
A. “Mild” narrowing ranges from 15% to 49% blockage of the artery. Over time, this narrowing can progress and lead to a stroke. Even if it doesn’t progress, mild narrowing is a sign of early blood vessel disease and calls for preventive measures. The presence of atherosclerotic plaque in the carotid artery is a predictor for future risk…
How is carotid artery stenosis diagnosed?
Carotid artery stenosis is usually diagnosed by color flow duplex ultrasound scan of the carotid arteries in the neck.
