Gamma Knife radiosurgery is an outpatient procedure designed to treat a wide variety of neurological disorders, including trigeminal neuralgia, acoustic neuroma, arteriovenous malformations, metastatic tumors, gliomas, meningioma, pineal tumors, and pituitary tumors. While the best way to determine if Gamma Knife radiosurgery is right for you is to consult with your neurosurgeon or oncologist it is important to educate yourself on what you can expect from the procedure.
After arriving at the Gamma Knife Center, a light-weight frame will be placed on your head using local anesthesia. This frame will stay in place throughout the duration of the treatment and is used as a reference point in addition to holding your head in position. Unlike other procedural methods, Gamma Knife surgery eliminates the risks associated with general anesthesia and causes only minimal discomfort.
Imaging and Treatment Planning
Once the frame is put in place, CT scans, angiography, or MRI technology is used to create clear images of the treatment site. These images are then used to design a customized treatment plan tailored to the exact dimensions of the tumor or cerebral arteriovenous malformation (AVM).
You will be transferred to a treatment couch on the Gamma Knife once the treatment plan has been created. At this point, the Gamma Knife radiosurgery procedure will begin, and it will typically last a few hours. You will remain awake during the treatment so that you can communicate with your neurologist as necessary.
Immediately Following Treatment
The head frame will be removed following treatment, at which point you will be observed for a short period of time. Most patients are able to return to normal activities one to two days following treatment.
