Leksell Gamma Knife is the only stereotactic radiosurgery (SRS) system specifically approved for treating brain tumors, also known as brain metastases, based on long-term scientific proof. By combining the precision of the Gamma Knife with the expertise and concern of the Memphis Regional Gamma Knife Center team, patients are offered a safe and effective alternative from a caring provider.
Despite its name, there is no knife. It's called Gamma Knife because of the surgical precision and effectiveness. The surgery requires no incisions or general anesthesia, and the procedure is virtually painless.
Studies show that local control-meaning the specific tumor treated does not come back-exceeds an average of 85 percent for the management of tumors in any brain location.
Over 2,000 medical papers have been published on Gamma Knife surgery, and 400,000 patients have been treated worldwide with a success rate of approximately 90 percent.
There is no other radiation treatment system as accurate as Leksell Gamma Knife since it was designed specifically to provide the very best radiosurgical treatment of brain tumors. To ensure accuracy, the radiation source never moves during the operation and the patient's head remains stationary. By avoiding movement during the procedure, the variables that reduce accuracy are avoided, providing patients with more effective treatment.
The noninvasive Gamma Knife can isolate and deliver a high dose of radiation to one or more brain tumors during a single treatment session.
Most people leave the hospital the same day and resume normal activities in a day or two.
Gamma Knife patients experience very little disruption to their daily routines and recovery times are drastically shorter than traditional surgery. Some patients may experience headaches, which can be treated with an over-the-counter pain reliever. There is no loss of hair or nausea, as with some treatments.
Because it's noninvasive, Gamma Knife surgery can be used to treat metastases in surgically inaccessible areas of the brain, such as the brainstem.
Patients who develop new brain mets can be treated again with Gamma Knife surgery.
