Build up of plaque in the carotid artery (situated in the neck and supplying blood to the brain)leads to stroke. Either clots, which form on the plaque, or both clots and plaque material may break loose suddenly and travel to the brain causing a stroke.
According to The American Stroke Association, the warning signs of stroke are:
* Sudden numbness or weakness of the face, arm or leg (especially on one body side).
* Sudden confusion, trouble speaking or understanding.
* Sudden trouble seeing in one or both eyes.
* Sudden trouble walking, dizziness, loss of balance or coordination.
* Sudden, severe headache with no known cause.
Carotid endarterectomy is a surgical procedure to remove the plaque from the carotid arteries. Here's a video on carotid endarterectomy (not recommended for the weak hearted!)
