Carotid arteries are blood vessels that supply the front and middle parts of the brain. The rear part of the brain is supplied by the vertebral arteries.

Blockages of these vessels can lead to paralysis (stroke) leading to weakness, vision disturbances and or death.

This type of stroke, known as ischemic stroke, accounts for approximately 87% of strokes.

Ischemic stroke can be caused by a problem with the blood vessels that supply the heart or the brain.

People with damaged blood vessels have a higher risk of recurrent attacks of stroke / paralysis.

Risk factors for carotid disease and stroke



Coronary artery disease

High cholesterol


Alcohol consumption

Physical inactivity

The increasing age

History of stroke


Imaging modalities such as Doppler ultrasound, CT or MRI angiogram are used to assess damage in the carotid arteries and the decision to intervene is based on the patient’s symptoms and imaging findings.

Method for treating carotid disease

An open or minimally invasive approach may be used to treat carotid disease depending on the patient and vessel status.

Carotid artery stenting

This is an endovascular procedure done by your vascular surgeon Dr. Ravikumar, whereby he uses the balloon for dilating the narrowed area and follows it by the placing a stent to keep the area wide open.

Carotid Endarterectomy

It is an open surgical procedure where the plaque that is narrowing the blood flow is taken out and the vessel is repaired.

Risks with interference

There is a risk of stroke during any procedure to treat carotid disease and Dr. Ravikumar will discuss your individual risk during your consultation
