Closed Stereotactic Surgery For Malignant Glioma
What you should know
Closed stereotactic surgery for malignant glioma is done to perform a biopsy on a tumor in the brain called a malignant glioma. A malignant glioma forms when brain cells called glial cells become cancerous. A small piece of the tumor is taken out during a biopsy and sent to a lab for tests.
Care AgreementYou have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.
- Your brain, eyes, bones, blood vessels, or nerves may get injured. You could have trouble breathing, develop an infection, or bleed more than expected after surgery. Problems may happen during the closed stereotactic surgery that may require caregivers to do open brain surgery. Even after surgery, there is a chance that another biopsy may have to be done.
- Without this surgery, the extent of the malignant glioma may not be known and proper treatment may not be given. The tumor may continue to grow and push other structures near it. If this happens, the blood or nerve supply may be cut off. You may have problems seeing, moving, speaking, breathing, or thinking clearly. This may lead to other serious medical problems, such as blindness, seizures, or stroke.
The week before your surgery:
- Ask a family member or friend to drive you home after your surgery. Do not drive yourself home.
- Ask your caregiver if you need to stop using aspirin or any other prescribed or over-the-counter medicine before your procedure or surgery.
- Bring your medicine bottles or a list of your medicines when you see your caregiver. Tell your caregiver if you are allergic to any medicine. Tell your caregiver if you use any herbs, food supplements, or over-the-counter medicine.
- You may need to have a CT scan or MRI scan. You may also need other tests, such as chest x-ray, electrocardiogram (ECG), and blood tests. Ask your caregiver for more information about these and other tests that you may need. Write down the date, time, and location of each test.
- Write down the correct date, time, and location of your surgery.
- Your caregiver may give you steroids and other medicines to use. These medicines help prevent seizures or stomach ulcers. Ask your caregiver for more information about these medicines.
The night before your surgery:
- Ask caregivers about directions for eating and drinking.
- Caregivers may give you a liquid medicine called an enema to help empty your bowel before the surgery. Your caregiver will give you directions for how and when to use an enema.
- You may be given medicine to help you sleep.
The day of your surgery:
- Ask your caregiver before you take any medicine on the day of your surgery. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital. Caregivers will check that your medicines will not interact poorly with the medicine you need for surgery.
- An anesthesiologist will talk to you before your surgery. You may need medicine to keep you asleep or numb an area of your body during surgery. Tell caregivers if you or anyone in your family has had a problem with anesthesia in the past.
- You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.
What will happen:
- The hair on your head may be removed. Your head will be placed on a head frame that is connected to a computer. The rigid head frame will be attached to your head with pins or screws. Scanned images of your brain will show pictures in three-dimensional (3-D) views on a monitor. This will help caregivers clearly see the different brain areas. This helps caregivers to target and biopsy your glioma more accurately.
- Your caregiver will insert a special needle into your scalp and skull through a small opening. The needle passes through your brain until it reaches the exact location of the tumor. The samples are sent to the lab for tests. A bandage is placed over the incision to control bleeding.
After your surgery:
You may be taken to a recovery room until you are fully awake. Caregivers will monitor you closely for any problems. Do not get out of bed until your caregiver says it is okay. When caregivers see that you are okay, you will be taken back to your hospital room. The bandages used to cover your stitches keep the area clean and dry to prevent infection. A caregiver may remove the bandages soon after your surgery to check your wound.
Contact a caregiver if
- You cannot make it to your appointment on time.
- You have a fever.
- You have questions or concerns about your surgery.
Seek Care Immediately if
- You have a sudden severe headache.
- You have trouble seeing, breathing, speaking, or thinking clearly.
- You passed out or had a seizure.
- Your face is getting numb or you cannot move your arms or legs.
