THE GAMMA KNIFE PROCEDURE - what to expect

When you first arrive to the unit, you will change into a hospital gown, the nurse will start an IV, you will be attached to an EKG monitor, and the nurse will administer medications to help you relax and for prevention of nausea.

Your procedure will begin with placement of an aluminum head frame, which is held into place by 4 screw-like pins in the very outer layer of the skull. You will have 2 pins inserted to your forehead and 2 pins inserted to the back of your head. Prior to the insertion of the head frame, numbing cream will be applied to the 4 pin site areas and then a local anesthetic will be administered to each pin site area. You may feel some discomfort for a short time. Additional medication to help you relax during head frame placement can be given if needed.

After placement of the head frame, you will be taken to radiology where an NMI will be obtained for localizing and planning your Gamma Knife treatment. If you are being treated for an AVM, you will have an angiogram as well. After completion of your MRI, you will return to the Gamma Knife unit where you will stay while the physicians and physicist study your films and "map" out your treatment time. This may take 1-2 hours. During this time you may watch television and visit with family members.

After treatment planning is completed, you will be moved into the Gamma Knife treatment room where you will be placed on the "couch" or Gamma Knife table. A large silver helmet will be attached to the table, and you head frame will be attached to this. Once all of the coordinates are set for your treatment, a microphone will be attached to your hospital gown, and the Gamma Knife team will leave the room. Monitors are set up for the physicians and physicist to watch you during the procedure, and the microphone will allow you to communicate with them. When the procedure begins, part of the Gamma Knife table will slide back into the dome, and the actual radiation treatment will begin. Your treatment may last anywhere from 30 minutes to 2 hours depending on you diagnosis.

After your treatment is completed, you will be removed from the Gamma Knife table, returned to the frame room and the head frame will be removed. A band-aid will be applied to each pin site.

At this time you may have something to drink and a light snack. Your total time in the Gamma Knife unit will be 4-5 hours. Approximately 30-minutes to 1 hour after your treatment completes, you will be transferred to your hospital room for an overnight stay for observation.
