Brain

    Awake brain surgery or intraoperative brain mapping refers to the procedure of removing the tumors in or near critical brain areas while the patient is awake and alert. A kind of anesthesia is used to numb the brain areas around the tumor or the damaged areas through the procedure. Actually, there are different techniques to perform the surgery and patient may be awake throughout the procedure, sedated at the beginning and end of the procedure and awake in the middle or sleeping at the beginning and end of the procedure and awake in the middle. The patient should be engaged and asked him/her some questions during the surgery to control patient’s different abilities and reactions such as talking, counting and looking at pictures etc. This technique is used to remove the gliomas and metastatic tumors as well as to treat the conditions such as Parkinson’s disease and epilepsy.

Awake Brain Surgery Benefits

    The awake brain procedure can reduce the lesions caused by Parkinson’s disease or tumors and also allows patient to resume control of everyday activities that influences on the quality of life. Moreover, it provides some benefits for the patients including:

    • Less need for care after the surgery
    • Less cost
    • Fewer neurological disorders
    • Short hospital stay
    • Less pain

Sides Effects

    Some of the complications of awake brain procedure may include:

    • Bleeding
    • Infection
    • Visual disorders
    • Brain swelling
    • Seizures
    • Muscle weakness
    • Difficulties with language skills and learning
    • Memory loss
    • Balance disorders
    • Stroke
    • Death

    Deep brain stimulation (DBS) refers to the procedure of implanting a device on both sides of the brain to send electrical signals to specific parts of the brain and regulate brain activities. It blocks the faulty nerve signals causing different neurological disorders. The device will be connected to the long-wires stimulator go under the skin of neck and chest. A DBS system consists of three components including the IPG or neuro-stimulator, lead, also called the electrode, and extension wire that all parts are placed inside the body. The patient can control it on and off. The DBS requires precise preoperative planning. So, MRI and CT scans of the brain should be examined to determine the target areas.
    It might need an additional surgery or remove the device due to breakage of the wire in the neck or some complications such as infection.

What Happens During Surgery?

    Step 1: inserting electrode in the brain
    While the area is numbed with local anesthesia, the electrodes are inserted in the specific areas of the brain. The patient should be conscious/alert as accuracy of the procedure should be confirmed through the patient’s reactions to the what are asked him/her.

    Step 2: inserting a battery-powered stimulator
    When inserting electrodes in the brain is performed successfully/ satisfactorily, the patient goes under general anesthesia to place a battery-powered stimulator under the skin of the chest. It allows the patient to adjust the side effects and can control the symptoms with a handheld wireless controller.

DBS Surgery Advantages

    DBS procedure provides some benefits for the patients that may include the following:

    • Controlling all body parts’ symptoms as it is performed on both sides of the brain
    • Adjusting the stimulation parameters
    • Controlling the continuous symptoms through a day
    • Reversibility
    • Patients can receive the future therapies

DBS Surgery Disadvantages

    DBS Surgery also includes some disadvantages such as:

    • High cost
    • Requiring expertise and training
    • Time consuming procedure for both physician and patients
    • Hardware problems

Side Effects

    Generally, each surgery includes some risks. The complications of deep brain stimulation may include:

    • Seizures
    • Infection
    • Bleeding in the brain
    • Blood clots
    • Reactions to anesthesia
