Treatment is required when a cerebral stenosis reaches 70% or more, or when a stenosis of 50% of that cerebral vessel has a cerebral ischemic event.
Endovascular stenting is the most effective method. It involves placing a stent in the stenotic area of the blood vessel, opening it and supporting the inner wall of the stenotic vessel to keep the plaque inside the vessel outside the stent, thus enlarging the diameter of the vessel to release the stenosis. It has the advantages of less trauma, less pain and shorter hospital stay. Shi Jin, Department of Neurology, Air Force General Hospital
