Carotid artery surgery is called “Carotid endarterectomy” surgery.
First of all, it is necessary to briefly talk about the blood circulation of the brain. The brain and heart are independent of general circulation rules. This is because they are both vital organs and for the purpose of protecting them. Both organs independently determine their own circulation. They are protected as much as possible from conditions such as low blood pressure in the body and the effects of the sympathetic nervous system that provides control.
Cerebral circulation is provided by two anterior (right and left) carotid arteries (carotid) and posteriorly by two vertebral vessels (vertebral artery). When the blood flow (stenosis or occlusion) decreases in one of these four main vessels by hearing from each other, the others increase the flow and provide adequate circulation.
The four vessels form a circulatory network that begins at the base of the brain. This network is called the Willis Polygon.
