Stereotactic brain surgery is usually used for elder patients.
Before the surgery, patients need to receive a thorough check-up and laboratory tests. After confirming the eligibility for treatment, they can receive the surgery with general anesthesia.
At the beginning of the surgery, a surgical frame will be fixed at four points on the patient's skull.
The CT scans will coordinate with the frame on the head to locate the exact position of the target area. An auxiliary frame will be connected to the surgical frame in the operating room, for the purpose of fixing the head in position.
There are small holes (about 0.8 cm size) created by the neurosurgeons at two points in the skull, and two needles can be inserted into the target area through the holes. Neurosurgeons will then deliver a maximum concentration of stem cells to the exact position of the target area. The wound will be closed after the procedure.
Not every one is eligible for this procedure; this surgery is recommended only when fine motor skills need to be improved, and particularly for adult patients since their regenerative ability is slower. Patients with high spasticity and have no or slight mental impairment can receive this procedure as well. But stroke patients or patients with severe epilepsy are ineligible for this surgery.
An entire day is required for the whole procedure. In fact, the surgery itself only takes less than an hour. But procedures such as inserting the frame, taking CT scans and injecting anesthesia cost a lot of time. Relatives or guides can only stay with the patients before he or she receives anesthesia, and they can meet the patient later during observation. Normally patients leave operation room in the late afternoon. Then they are taken to the observation room and monitored for a day. After that, they can leave the room if no complications occur. Patients can eat or walk the next day, but they need to avoid wetting their head for a few days. Nurses will help patients to change bandages regularly, and the staples will be removed after a week.
