Simple illustrations of Carotid Endarterectomy Procedure

Carotid Endarterectomy or may be called Stroke Prevention Surgery is indicated to prevent a stroke in patients with narrowed carotid arteries(Endarterectomy is the removal of material on the inside "end-" of an artery).

Procedure: The carotid artery is exposed through an incision on the side of the neck. The artery is clamped above and below where the narrowing is located. The flow of blood to the brain is maintained with the use of a specialized shunt (tube) that carries fresh blood to the brain during the procedure. The diseased material narrowing the artery is removed. The artery is then closed.
