What else can I help you with?
What device will be fixed to the patient's head on the morning of a pallidotomy procedure?
On the day of the surgery, the stereotactic frame will be fixed to the patient's head.
Why is a MRI administered after the stereotactic frame is affixed to the pallidotomy patient's head?
A final MRI is done with the frame in place to help set the coordinates of the GPi in relation to the frame.
How does the stereotactic frame work during the pallidotomy procedure?
This device is a rigid frame attached to the patient's head, providing an immobile three-dimensional coordinate system, which can be used to precisely track the location of the GPi and the movement of the probe.
What specialist performs the pallidotomy?
Pallidotomy is performed in the hospital by a neurosurgeon, in coordination with the patient's neurologist.
What happens during a pallidotomy?
To destroy tissue in the GPi, a long needle-like probe is inserted deep into the brain, through a hole in the top of the skull. To make sure the probe reaches its target exactly, a rigid "stereotactic frame" is attached to the patient's head.
What length of time is a pallidotomy patient typically hospitalized?
Some centers perform pallidotomy as an outpatient procedure, sending the patient home the same day. Most centers keep the patient overnight or longer for observation.
What is a pallidotomy patient given to ease his anxiety?
The patient will receive a mild sedative to ease the anxiety of the procedure.
How soon after surgery does a pallidotomy patient feel better?
Patients will feel improved movement immediately.
Why is the patient asked to make movements during a pallidotomy?
During the procedure, the patient will be asked to make various movements to assist in determining the location of the electrode.
Why is a patient's medication sometimes adjusted after undergoing a pallidotomy?
Medications may be adjusted somewhat to accommodate the changes in symptoms.
Why is it essential that a patient stay awake during a pallidotomy?
In addition, the patient must remain awake in order to report any sensory changes during the surgery.
What condition is taken into account when determining whether a patient should undergo a pallidotomy?
Pallidotomy is performed in patients with Parkinson's disease who are still responsive to levodopa, but who have developed disabling drug treatment complications known as motor fluctuations.
