Drug treatment has a significant effect on the early stage of Parkinson's disease, but as the disease progresses, the drug effect gradually becomes smaller and there will be a switching phenomenon. As a result, more and more patients choose to undergo surgery to treat Parkinson.
Advantages of brain pacemaker implantation
The brain pacemaker is a specific nerve nuclei implanted in the brain of Parkinson's patients, releasing high-frequency electrical stimulation, stimulating the related nerve nuclei in the brain to control the movement, inhibiting these over-excited due to the reduction of dopaminergic neurons. The electrical impulses of neurons reduce their over-excited state, thereby alleviating the symptoms of Parkinson's disease and allowing patients to recover from their activities and self-care.
The brain pacemaker is currently the most advanced method in the world. It can be used on both sides, reversible and adjustable, and controlled by weak current in vitro, the effect is better. The first hospital to carry out Parkinson's surgery was Tangdu Hospital of the Fourth Military Medical University of Xi'an. The first case of destruction was carried out in 1997. In 1998, it was introduced and operated with brain pacemaker surgery. It still maintains the largest number of Parkinson in the country. Rehabilitation cases.
In recent years, as people's living standards have improved, more and more Parkinson's patients are no longer satisfied with the drug's reluctance to control symptoms, and more and more brain pacemakers are selected by Parkinson's patients. Is this surgery risky?
Is there a risk of brain pacemaker implantation?
Neurosurgery at Tangdu Hospital of the Fourth Military Medical University has several steps in the implementation of brain pacemaker implantation: firstly, a stereotactic headgear is installed, and the positioner helps the doctor to determine the position of the electrode; then CT or magnetic resonance ( MRI) Check the position of the directional frame for precise positioning to help the doctor obtain positioning data for the implanted brain pacemaker. Local anesthesia is used in these procedures, and the patient does not feel pain or risk.
The next step is to start the operation. The doctor will locate the stimulation site according to the previous position and put the electrode into the brain. The damage caused by this process is very small, and since the brain itself has no pain, it will not feel pain; after the electrode is implanted, the doctor will further adjust the position and stimulation intensity of the electrode to achieve the best effect; finally implant the whole system, including A pulser (brain pacemaker battery and wire) was sutured and bandaged. The components implanted in the body do not cause rejection and do not affect the patient's daily life.
