Carotid stenosis: surgery, stent or medical treatment?
Reviewed on July 17, 2026
Carotid stenosis — narrowing of the main artery carrying blood to the brain — is one of the preventable causes of stroke. The question is almost always the same: is medication enough, or is intervention needed? The answer varies from person to person, and erring in either direction has consequences.
What carotid stenosis is
It is the buildup of fatty plaque (atherosclerosis) that narrows the carotid artery in the neck. Fragments of this plaque can break off and block brain vessels, causing a stroke or a TIA (a 'mini-stroke').
The degree of narrowing is measured as a percentage and is one of the central factors in the decision.
Symptomatic or asymptomatic
Symptomatic stenosis has already caused a stroke, TIA or temporary loss of vision. In these cases, the benefit of intervening is usually greater.
Asymptomatic stenosis is found on routine tests, without events. Here the decision is more delicate: often the best treatment is medical, with strict control of cholesterol, blood pressure and antiplatelet therapy.
Still unsure about your case?
Send your exams and your case history and receive a structured, written opinion from an independent specialist physician.
Request a second opinionThe treatment options
Medical treatment: medication and lifestyle change, always the foundation of everything.
Endarterectomy: surgery that opens the artery and removes the plaque. It is the historical standard, with solid results.
Angioplasty with stent: via catheter, the artery is opened and a stent keeps it patent. A less invasive alternative, useful in selected cases.
Why seek a second opinion
The indication depends on the degree of stenosis, whether you have had symptoms, your surgical risk and the quality of the imaging. There are many variables, and the evidence keeps evolving.
An expert second opinion helps separate what truly changes your stroke risk from what would be unnecessary intervention.
Frequently asked questions
Does asymptomatic carotid stenosis need surgery?
Not always. Many asymptomatic cases are better treated with medication and risk-factor control. The decision is individual.
Stent or open surgery?
Both reduce stroke risk in indicated cases. The choice depends on anatomy, age and each patient's risk.
How do I get a second opinion?
Upload your imaging and reports on Revidra and receive a written opinion from an independent specialist.
