Carotid arteries (left and right) situated inside the neck are responsible for majority of the blood supply to the brain. The common carotid artery branches into two arteries
Atherosclerotic disease commonly affects the carotid bifurcation. Atherosclerotic plaques deposited over the inner surface of the artery causes narrowing (stenosis) of the vessel.
Transient Ischaemic Attack (TIA): occlusion (closure or blockage) of blood vessel of the brain causing lack of blood supply (ischaemia) to the brain cell for a short period of time.
Stroke (ischaemic): occlusion (closure or blockage) of the blood vessel of the brain and cannot be corrected by the body resulting in permanent brain cell death over certain region. }
Stroke is the third most common cause of death and the leading cause of disability in many developed countries.

- Surgical procedure performed under general anaethesia or regional nerve block
- Diseased carotid artery is exposed through an incision over the neck- Artery is clamped temporarily and the diseased part is opened
- Blood flow to the brain can be restored using a shunt if necessary
- Atherosclerotic plaque together with the most inner lining of the vessel is removed
- Vessel is repaired with or without additional synthetic patch after plaque is removed.
