Your symptoms and condition will indicate whether cholesterol-lowering drugs, high blood pressure medications, and/or blood thinners should be prescribed to lower your risk for serious complications.
Intracranial Balloon Angioplasty and Stenting
A neurosurgeon makes a small incision, inserts a catheter, and guides it through your circulatory system to the blocked artery. Next, a small flexible balloon is inflated, pushing plaque back against the artery walls and opening the blockage. Finally, after the balloon is deflated, a small stent is placed, which reinforces the vessel walls and helps keep it open. This procedure is ideal for people who have moderate to severe stenosis.
Cerebral Artery Bypass
Through an open incision in the skull, neurosurgeons reroute blood flow around the blocked artery using a replacement blood vessel from another part of your body. The new artery bypasses the damaged blood vessel and restores healthy blood flow in the brain. This procedure is ideal for people with severe (100%) stenosis.
