Parkinson’s surgery in Iran at Erfan Hospital

The surgery is generally carried out in two stages. First, a local anesthetic is applied to the scalp before surgery and very fine wires (with electrodes at the tips to deliver electrical signals) are inserted into the brain at the targeted region.

The second stage may be carried out under general anesthesia. A wire is implanted to connect the electrodes to a neurostimulator, which generates the electrical pulse that is delivered by the electrodes. The neurostimulator is generally implanted below the collarbone, but can also be placed in the lower chest.

Once the device has been implanted, the symptoms can be monitored and the setting of the neurostimulator can be adjusted to best suit the patient’s needs. Re-programming is noninvasive because it can be performed wirelessly using an antenna held near the site of the neurotransmitter.
