What is intracranial atherosclerosis?
Intracranial simply means “inside the skull.” Atherosclerosis is a hardening of the arteries. So, intracranial atherosclerosis is a narrowing and hardening of the arteries in the skull. Generally there are no symptoms until the arteries are so clogged with plaque that blood can no longer flow through them. In fact, most people find out they have this problem only after they have already had a stroke.
Who has it?
Because there are no symptoms, we don’t really know how many people have some degree of atherosclerosis in their brain arteries. What we do know is that about 70,000 people in the U.S. each year have a stroke caused by narrowed arteries in the skull about 8-10% of all ischemic or clot-caused strokes.
Risk for intracranial atherosclerosis increases if a person:
How do you diagnose it?
A doctor may be able to diagnose intracranial atherosclerosis by looking at the blood flow in your brain. A variety of tests can do this. Some take pictures of your blood vessels using a type of X-ray. With these tests, a doctor can see if the arteries are diseased, narrowed, enlarged, or blocked altogether. Other tests use sound waves to study your blood flow. Each test is quick and painless. They are ordered by a doctor and performed by a trained examiner or radiologist.
What is the treatment?
Intracranial atherosclerosis is hardening of the arteries in the brain. It is usually discovered after a stroke occurs. Experiencing a stroke once means increases the chance of a recurrent stroke. Talk to a doctor about making lifestyle changes that can also slow down the development of atherosclerosis.
Recommended lifestyle changes include:
A doctor may also suggest medicines to prevent TIAs and stroke. These medicines may include:
If the arteries are greatly blocked, a doctor may suggest either angioplasty and/or stenting to open them up. For both procedures, a thin tube called a catheter is inserted in the groin or thigh area. From there it is threaded up through the body to the site of the diseased artery. A dye is injected into the arteries so that the doctor is able to see the blockage on an X-ray machine.
If angioplasty is performed, a small balloon at the end of the catheter is inflated at the blocked area. The balloon pushes against the built-up plaque and compresses (flattens) it. At the same time it also widens the blood vessel. As a result, the blocked artery opens up and blood flow is restored. If stenting is performed, a small stent (a wire mesh tube) at the end of the catheter is placed in the artery. The stent expands to fit the size and shape of the artery wall. It is designed to open the artery and prevent future blockages.
Though both procedures usually require a hospital stay of one or two days, they are not considered surgery. These procedures are typically performed by a neuroradiologist or a neurosurgeon.
For stroke survivors who do not respond to current treatments such as aspirin or bloodthinning drugs, angioplasty with stenting is an option. Currently, the Wingspan™ Stent System is the only treatment approved by the Federal Drug Administration for treating intracranial atherosclerotic disease.
