Cerebral Stenosis

Cerebral Stenosis

Call for an Appointment

Duke's neurosurgeons identify and treat cerebral stenosis, also known as intracranial stenosis, which occurs when blood flow to the brain is restricted by arteries narrowed or blocked by plaque. We use sophisticated imaging to diagnose the severity of your condition, and aggressively treat brain stenosis to reduce your risk of stroke. If surgery is recommended, our highly skilled surgeons open blockages in the small twisting vessels found deep within the brain.

Your symptoms and condition will indicate whether cholesterol-lowering drugs, high blood pressure medications, and blood thinners are prescribed to lower your risk for serious complications.  

Intracranial Balloon Angioplasty and Stenting

A small flexible balloon is used to open the narrowed or blocked artery, and a small cylindrical device called a stent is placed to keep the blood vessel open. While there are some risks to this procedure, preliminary evidence suggests this combination is more effective than medication alone in preventing long term stroke.

Cerebral Artery Bypass

Reroutes blood flow around blocked, narrowed or damaged arteries in the brain. Often essential in emergencies, a cerebral bypass may be required to restore healthy blood flow.

CT Scans

High resolution images the brain vessel indicate where the brain's blood supply may be restricted by a narrowed or blocked artery.

Magnetic Resonance Angiogram (MRA)

A contrast dye is injected through an IV to create images of blood flow in the arteries and blood vessels in the neck and brain.

Cerebral Angiography

A catheter is inserted into a large artery and threaded through the circulatory system. A contrast agent is injected to capture images that allow neuroradiologists -- specialists in the nerves found in the brain and spine -- to view abnormal connections within arteries and veins and plan the appropriate treatment.
