An interruption or reduction in the supply of blood to the brain causes a cerebral stroke. This lack of supply results in the lack of oxygen or nutrients to the brain and leads to death of brain cells. Blood flow could also be affected as a result of a ruptured artery to the brain, or blockage.

Although it is a common medical issue, a healthy lifestyle can effectively prevent it.

Strokes are divided into three kinds namely ischemic Stroke, haemorrhagic stroke and transient ischemic attack (TIA). A cerebral stroke is an emergency that calls for immediate attention by a specialist.

The objective of carotid endarterectomy (CEA) is to prevent strokes. Carotid endarterectomies are performed to prevent stroke The surgery has been found to be highly beneficial for persons who have already had a stroke or experienced the warning signs of a stroke and have a severe stenosis of 70 percent to 99 percent. The benefit of carotid endarterectomy for preventing recurrent stroke is maximal when surgery is performed within 2 weeks after ischemic stroke or transient ischemic attack; the benefit is reduced when surgery is delayed >2 weeks and essentially lost if delayed >3 months.
