An example of a difficult operation is that of the large acoustic neuroma. There is a serious risk for loss of facial function on one side of the face, and a risk for swallowing difficulties after the operation. The latter could also lead to postoperative pneumonia.
An example of a simple operation with a fairly high postoperative morbidity is the placement of a "shunt" for something called "normal pressure hydrocephalus." This patient is at serious risk for developing subdural hematomas or CSF accumulations, requiring further surgery(ies) and even possible removal of the shunt. (All of this can occur because a brain like this has become like walnuts in a shell, smaller than their supportive coverings.)
The bottom line is: ask for all of what you really want to know.
If you are the type that doesn't want to know, don't be afraid to say so!
Certain problems may require a cerebral angiogram to be performed, so that the surgeon has a "blood vessel" road map prior to surgery. Functional studies (special MRI, EEG, or magnetoencephalography) also might be necessary to guide the surgeon where not to go.
Cerebral blood flow studies (SPECT, Xenon studies or transcranial doppler studies) may be important to show the surgeon the state of your brain's blood supply reserves. You'll get an IV catheter the night before surgery; you'll be given various medications to prevent seizures, temporarily remove brain water (like medically squeezing a sponge), so the surgeon doesn't need to retract too much during surgery. You'll also be given antibiotics (to prevent infection). If you have an allergy to an antibiotic, make sure everyone knows it.
The night before surgery is usually full of anticipation. More often than not, you'll be the one comforting your family and friends. If you're afraid, thats only normal. Sometimes, sleep is difficult, so don't hesitate to ask for sleeping medication, if you want it.
Now is usually a good time to plan for how you will approach the postoperative recovery period. Many patients tell me that it is very much like gearing up for a sporting event, important business meeting, or even making a New Year's resolution. You can leave the surgery to the doctors, but you are in charge of your recovery. Think about just how well you are going to be after surgery. A positive attitude and God are your surgeon's best allies. The two of you are really in this together.
