Under x-ray guidance, a flexible tube-like wire mesh (a stent) is positioned and expanded across the blockage in the artery. The stent pushes the cholesterol deposit out of the way and restores blood flow The internal carotid artery (ICA) and its main branches supply the cerebral hemisphere and part of the deep, subcortical areas. Carotid artery stenting is a procedure that is performed under local anesthesia using a small tube that is inserted into an artery in the groin area of the leg.
