Dr. Li Weiguo specializes in surgical treatment of Parkinson’s disease, minimally invasive treatment of intractable epilepsy, trigeminal neuralgia and facial spasm, and minimally invasive surgical treatment of common neurosurgical diseases, such as brain and intravertebral tumors, cerebrovascular diseases and hydrocephalus. If patients want to see Dr. Li Weiguo for brain pacemaker installation, they need to know the following treatment process Day of outpatient consultation for Parkinson’s patients – the doctor initially assesses whether the patient is suitable for the installation of a brain pacemaker, and patients who are suitable for surgery make an appointment and wait for admission. The day the patient is admitted to the hospital until the day before surgery – a routine preoperative checkup is done. If you already have a routine preoperative checklist within three months, you can provide it to the doctor for reference, which is common to all major hospitals. Pre-operative levodopa test and MRI will also be done for further confirmation. Day of surgery – On the same day, you will enter the operating room to install the head frame and go to the CT room for scanning. These tests need to be performed in our hospital, and similar tests in other hospitals cannot be shared. After these tests are completed and the surgical procedure is determined, the surgery will officially begin. At the beginning, local anesthesia is applied to the brain, stimulation electrodes are inserted, and once the target site is found, the patient is awakened and the doctor interacts with the patient to assess the improvement of symptoms; if the patient feels very good during the operation and can move freely by himself, it means that there is no problem in stimulating the target site. The next step is to use general anesthesia and bury the lead and electrodes under the skin. About one month after the surgery – the power is turned on and regulated. Some patients wonder why they have to turn on the pacemaker after a period of time when it is installed. In fact, the surgical insertion of microelectrodes has a slight destructive effect on the lesion, and the place where the electrodes are inserted will have a slight edema after surgery, which can have the same effect as the electrode stimulation for a period of time, so there is no need to turn on the machine for a while during this period. When the edema gradually subsides and the micro-destructive effect is gradually reduced, the machine can be turned on to function. After the machine is turned on, the vast majority of patients respond very well, but some patients may feel some discomfort, and then it is time to adjust the stimulation parameters. There are thousands of combinations of parameters, and only by finding the right parameters for the patient can the machine be used to its maximum effect. After turning on the machine and adjusting the parameters, the patient can go home to recuperate, usually after a month to the hospital for follow-up and adjustment again. Later is the interval of six months to a year to come to the hospital for follow-up debugging once, until the patient’s state can control the stability.
