Treatment Options Cerebral Artery Stenosis
The first step to treating cerebral artery stenosis is usually medication. Blood thinners such as aspirin or clopidogrel can help prevent a clot from forming in the artery. Statins can help prevent the continued build up of cholesterol plaque in the artery.
If the narrowing of the artery is severe, and doesn't respond to medications or is greater than a 50% blockage, more invasive treatment may be needed. The main options for treating narrowing of the arteries in the brain are:
- Angioplasty to reopen the artery with possible stenting, or
- Cerebral artery bypass surgery.
Angioplasty With Possible Stenting to Treat Cerebral Artery Stenosis
This procedure takes place in the angiography suite. During this procedure, a tube is inserted into an artery in the groin and threaded to the narrowed artery. A small balloon is inserted into the tube. When it reached the narrowed part of the artery, it is opened up. This is called angioplasty.
Then a small, mesh tube device is inserted through the tube in the groin to the area where the narrowing was. This device is called a stent. The stent is put into place and left in the artery. Overtime, the tissues of the artery grow around the stent.
