Gamma Knife radiosurgery doesn’t involve surgical incisions, so it’s generally less risky than open craniotomy where the possibility exists for problems with anesthesia, bleeding and infection.
Early side effects following Gamma Knife radiosurgery are usually temporary. They may include:
Fatigue – Fatigue and tiredness may occur for the first few weeks after Gamma Knife radiosurgery. This is very common after any radiosurgery treatment.
Swelling – Swelling in the brain at or near the treatment site can cause symptoms such as headache, nausea or vomiting. Your doctor may prescribe corticosteroid medications to prevent such effects from occurring or may wait to treat symptoms if they should appear.
Scalp and hair concerns – Redness, irritation or sensitivity may occur at sites where the frame is attached to your head. Rarely, patients may experience some temporary hair loss.
Other side effects may occur dependent upon the target site and the dose of radiation received. This should be discussed thoroughly with your treating physician.
