The Gamma Knife procedure

The average Gamma Knife procedure, including frame fixation, neuro-imaging, treatment planning and the actual treatment, takes 1-3 hours.

Imaging tests

A member of the Gamma Knife Team accompanies each patient to the imaging area and depending on the medical condition an MRI, CT scan or both may be needed. AVM patients may also have an angiogram. These diagnostic tests may take 1-4 hours to complete.

After the images are taken

Patients will return to the Gamma Knife Center and be able to relax while the Gamma Knife team reviews the images and maps out a personal treatment plan. This may take 1-2 hours. Individuals can read, rest and visit with family in a private waiting area.

The treatment itself

Once a personalized treatment plan has been mapped out, patients are moved to the actual Gamma Knife unit and are asked to lie on a special bed. Next, the gamma rays are administered to the predetermined spot. This may take anywhere from 30 minutes to 3 hours depending on the number of doses required. Patients are awake and alert the whole time and will not feel any pain. They will be able to talk to our nurses and doctors and will be observed on a closed circuit television.

Recovery

Generally, there are no side effects, but some patients may experience a minor headache or some swelling. If so, a nurse will administer some medication and alert the doctors. Patients requiring an angiogram will need to remain flat on their back for 8 hours following the test. Some patients may go home the same day of treatment and others may be required to stay overnight. Most should be able to return to a normal routine, including work or school, the day after treatment.

Follow-up care

Follow-up care is very important and each patient will be given specific instructions. Patients who go home the same day will be called by our coordinator the next day. In addition, our doctors will stay in touch with each patient's regular physician. The effects of treatment occur over a period of time, depending on the medical condition treated. As a result, periodic diagnostic imaging tests will be required. Patients must continue to take any medication until a doctor advises otherwise.

It's all done with a personal touch

At Aurora St. Luke's Medical Center, we don't believe it's enough to offer high-tech treatment. Personally knowing and caring for each patient as an individual is equally important to us. We call it our “high-tech, high-touch” philosophy.
