About Gamma Knife Radiosurgery Procedure
What to expect
Before the actual procedure and after making some initial preparations, you’ll be fitted with a lightweight, box-shaped frame that will hold your head in place during surgery. You may feel some slight pressure as the frame is fitted but after it is on you should feel little discomfort. A collimator helmet will then be placed over the frame. You will be able to breathe and see out of the helmet as well as communicate with your treatment team throughout the procedure. The head frame is put in place to keep the head still. Then the doctors use imaging tests such as CT scan and MRI to detect the exact location of the lesion in the brain. Based on these scans, a dedicated treatement plan is created to pinpoint the lesion.
Once all the data is entered and confirmed, you’ll be placed on the unit’s couch and your helmet will be locked into place in the guiding device.
When the procedure is through, the helmet and frame will be removed and the attachment points will be treated with an ointment and gauze to promote healing, followed by a bandage. You should be able to go home the same day, so you’ll want to make sure someone comes along with you to drive you home and stay with you until any of the side effects (mild headache and/or nausea) have worn off.
The Gamma Knife procedure often takes less than one hour to plan and less than one hour to treat. Most patients are back home resuming their regular activities later that day. No medicines have to be discontinued and no other concomitant therapies have to be delayed for Gamma Knife to be performed. Usually only one treatment is needed to shrink the tumor. The results can be seen over time, so this treatment is not recommended for patients who need emergency care.
