NeuroEndovascular Surgery

When every minute counts, you need the best and you need it fast.

At Mountain States Medical Group, we understand surgery can be an intimidating process. But, we are proud to offer neuroendovascular surgery to our region, which provides minimally invasive procedures and shorter recovery times for patients with neurological diseases.

How does it work? A small catheter is threaded through an artery or vein to the area that needs treatment. Once the catheter has reached its destination, treatment can be administered through the catheter. This technique dramatically reduces trauma associated with treating neurological diseases through other types of surgery.

Our specialists are highly trained and utilize state-of-the-art technology and facilities to offer customized care. If you need neuroendovascular surgery, rest assured, we are prepared and ready to care for you – because at Mountain States Medical Group, your health is our passion.

Some of the diagnoses we treat include:

  • Arterial fistulas
  • Arteriovenous malformations
  • Brain aneurysm
  • Brain tumor
  • Intracranial aneurysm
  • Intracranial and extracranial arterial stenosis
  • Stroke

Our “Life Saved” videos feature grateful stroke survivors and their stories about their experience and the treatment they received from our neuroendovascular team at the Stroke Center at JCMC.

What is a stroke?

A stroke, which can also be referred to as a brain attack, occurs when blood flow to the brain is disrupted. Disruption in blood flow is caused when either a blood clot blocks one of the vital blood vessels in the brain (ischemic stroke), or when a blood vessel in the brain bursts, spilling blood into surrounding tissues (hemorrhagic stroke). The brain needs a constant supply of oxygen and nutrients in order to function. Even if there is a brief interruption in blood supply it can still cause problems. Brain cells begin to die after just a few minutes without blood or oxygen due to both the physical and chemical changes that occur in the brain with stroke, damage can continue to occur for several days. Impairment of brain function occurs with the loss of brain cells. The impairment of brain function may include impaired ability with movement, speech, thinking and memory, bowel and bladder function, eating, emotional control,and other vital body functions. Recovery from stroke and the specific impaired ability depends on the size and location of the stroke. A small stroke may result in problems such as weakness in an arm or leg, whereas larger strokes may cause paralysis, loss of speech, or even death. 

What can I expect if I am having surgery?

You will be given specific instructions on the time to arrive at the hospital and where to check in. Once checked in you will be directed to a Pre-Operation area where you will change into a hospital gown, and you may get white stockings to wear to help prevent blood clots in your legs after surgery. Our endovascular nurses will talk with you about the type of anesthesia and pain medication you will be receiving, and an IV line will be placed in your arm for fluids and medicine throughout your surgery. 

As with all surgeries, you will be asked to sign a standard consent form prior to surgery and your surgeon will discuss the specifics of any risks associated with your individual situation. If you have any questions prior to surgery, please do not hesitate to ask your doctor or any other member of your health care team.

Please visit our Health Library to learn more about NeuroEndovascular Surgery and other medical conditions, treatments, nutrition, healthy living and general wellness. You will also find a Symptom Checker to help you evaluate whether the symptoms you are experiencing can be taken care of at home or if you need medical attention.
