Carotid endarterectomy (CEA) is a surgical treatment for carotid artery disease. The carotid arteries are the main blood vessels that carry oxygen and blood to the brain. In carotid artery disease, these arteries become narrowed. This reduces blood flow to the brain and could cause a stroke.

Gamma Knife uses very precise beams of gamma rays to treat an area of disease (lesion) or growth (tumor). It’s most often used in the brain.
...more
Laminectomy is a type of surgery in which a surgeon removes part or all of the vertebral bone (lamina). This helps relieve compression of the spinal cord or the nerve roots that may be caused by injury, herniated disk, spinal stenosis (narrowing of the canal), or tumors.

A lumbar disk replacement involves replacing a worn or degenerated disk in the lower part of the spine with an artificial replacement made of metal or a combination of metal and plastic.
...more
A lumbar puncture (LP) or spinal tap may be done to diagnose or treat a condition.

Magnetic resonance angiography or MRA is a type of imaging test that allows a healthcare provider to look at the body's blood vessels.
...more
Magnetic resonance imaging (MRI) uses a large magnet, radiofrequencies, and a computer to make detailed images of organs and structures within the body, in this case, the brain and spine. MRI is used to help diagnose a health problem.
...more
A myelogram is a diagnostic imaging test generally done by a radiologist. It uses a contrast dye and X-rays or computed tomography to look for problems in the spinal canal. Problems can develop in the spinal cord, nerve roots, and other tissues. This test is also called myelography.
...more
A nerve conduction velocity test measures how fast electrical impulses move through your nerves. The test is used to identify nerve damage.
...more
A positron emission tomography (PET) scan is a type of nuclear medicine imaging test. It is used to examine various body tissues to identify certain conditions by looking at blood flow, metabolism, and oxygen use. PET scans may also be used to see how well the treatment of certain diseases is working.

This therapy targets the sympathetic nervous system, a series of nerves that spread out from your spine to your body to help control several body functions, including blood flow.
...more
X-rays use invisible electromagnetic energy beams to make images of internal tissues, bones, and organs on film. Standard X-rays are done for many reasons, including diagnosing tumors or bone injuries.
