Vagus nerve electrical stimulation surgery is known as VNS surgery VNs are used to treat patients with intractable epilepsy, and as of 2015 statistics, more than 100,000 patients worldwide have adopted this novel treatment. Because VNS therapy does not require craniotomy, even if the definitive epileptogenic lesion cannot be detected by imaging, and because it does not require craniotomy, but only surgery under the skin of the neck and chest, the surgery is less invasive and risky, which gives new hope to both patients and physicians. Even more gratifying is the fact that vagus nerve stimulation not only controls seizures, but also saves the patient’s intelligence. Many patients with epileptic encephalopathy experience mental regression, and VNS can maximize the protection of the patient’s intelligence. the effectiveness of VNS increases with the duration of treatment. The VNS procedure is a minimally invasive procedure, unlike traditional craniotomy. The first step of the treatment is to implant a set of electronic devices under the skin: a spiral electrode is placed on the surface of the vagus nerve in the left side of the neck, then an electrical stimulation pulse generator is implanted under the skin on the chest, and the two are connected with a flexible wire. After a week the surgical incision has healed. The more important second part will begin: setting the stimulation parameters and turning on the electrical stimulation. The surgeon will use a magnetic remote control device through the patient’s clothing to set the output current intensity and frequency of the stimulator in the patient’s body to obtain the most satisfactory seizure control. Because VNS surgery is minimally invasive and has few significant side effects, it is done as the preferred surgical treatment for epilepsy in developed countries such as the United States. What kind of patients are suitable for VNS? 1. Patients aged 18 months-69 years with drug-resistant epilepsy that cannot be controlled after 1-2 years of combined treatment according to national standards. 2. Refractory epilepsy that does not accept or is not suitable for surgical removal of intracranial lesions. 3. Patients who have failed surgical treatment and have no special approach to treatment. Vagus nerve electrical stimulation surgery is another surgical treatment for drug-refractory epilepsy, and patients with epilepsy can try this treatment if it does not work well. It is important to have a regular professional evaluation by a physician to determine if this treatment is appropriate.
