WHILE YOU ARE HERE:
Before your surgery:
- Informed consent is a legal document that explains the tests, treatments, or procedures that you may need. Informed consent means you understand what will be done and can make decisions about what you want. You give your permission when you sign the consent form. You can have someone sign this form for you if you are not able to sign it. You have the right to understand your medical care in words you know. Before you sign the consent form, understand the risks and benefits of what will be done. Make sure all your questions are answered.
- An IV is a small tube placed in your vein that is used to give you medicine or liquids.
- Local anesthesia is a shot of medicine put into the areas of your head where the frame will be placed. It is used to numb the area and dull the pain. You may still feel pressure or pushing during surgery.
During your surgery:
- Your healthcare provider will inject local anesthesia in the areas of your head where the head frame will be placed. The head frame will be attached to a helmet placed over your head.
- When your surgery starts, the bed you are lying on will be moved inside the treatment hood. Your healthcare provider will use the computer to aim beams of radiation into the holes of the helmet. These beams will pass through your skull and brain until they reach your tumor. A computer will show pictures of your brain to your healthcare provider.
After your surgery:
You will be taken to a room to rest until you are fully awake. You will be monitored closely for any problems. Do not get out of bed until your healthcare provider says it is okay. You will then be able to go home or be taken to your hospital room.
- You will be helped to walk around after surgery. Movement will help prevent blood clots. You may also be given exercises to do in bed. Do not get out of bed on your own until your healthcare provider says you can. Talk to healthcare providers before you get up the first time. They may need to help you stand up safely. When you are able to get up on your own, sit or lie down right away if you feel weak or dizzy.
- Medicines may be given to relieve pain or nausea. You may also need medicines to prevent seizures or a bacterial infection. Medicines may be given to decrease swelling in your brain. This may help increase blood flow to your brain.
You may need open brain surgery if problems occur during gamma knife surgery. Your brain, eyes, bones, blood vessels, or nerves may get damaged during surgery. Radiation may cause nausea, vomiting, skin or blood problems, or seizures. Surgery may not completely remove the tumor, or the tumor may come back. You may get a blood clot in your leg or arm. This may become life-threatening.
