Vagus nerve stimulation involves using a device to stimulate the vagus nerve with electrical impulses. There's one vagus nerve on each side of your body. The vagus nerve runs from the lower part of the brain through the neck to the chest and stomach. When the vagus nerve is stimulated, electrical impulses travel to areas of the brain. This alters b...
Having a vagus nerve stimulator implanted is safe for most people. But it does have some risks, both from the surgery to implant the device and from the brain stimulation.
It's important to carefully consider the pluses and minuses of implanted vagus nerve stimulation before having the procedure. Make sure you know all of your other treatment choices. Be sure that you and your health care provider feel that implanted vagus nerve stimulation is the best option for you. Ask your provider exactly what to expect during s...
Before the procedure
Before surgery, you'll have a physical exam. Your surgeon may have you start taking antibiotics before surgery to prevent infection.
During the procedure
Surgery to implant the vagus nerve stimulation device often is done on an outpatient basis in which you go home afterward. During surgery, you'll likely be put into a sleep-like state. This is done with general anesthesia. The surgery itself doesn't involve the brain. Two cuts, known as incisions, are made. One is made on the chest or in the armpit area. The other is made on the left side of the neck. The pulse generator is implanted in the upper left side of the chest. The pulse generator is...
After the procedure
If you had the device implanted to treat epilepsy or depression, the pulse generator is turned on during a medical visit a few weeks after surgery. Then it can be programmed to deliver electrical impulses to the vagus nerve at various durations, frequencies and currents. Vagus nerve stimulation usually starts at a low level. It's gradually increased depending on your symptoms and side effects. Stimulation is programmed to turn on and off in cycles — such as 30 seconds on, five minutes off. Yo...
If you had the device implanted for epilepsy, it's important to understand that vagus nerve stimulation isn't a cure. Most people with epilepsy won't stop having seizures. They'll also likely continue taking epilepsy medicine after the procedure. But many might have fewer seizures — up to 50% fewer. The seizures also may be less intense. It can tak...
