Minimally Invasive Brain Surgery
The prospect of having a surgical procedure performed on the brain can be frightening for you as a patient. The experts at your hospital can help put your mind at ease with today’s minimally invasive MRI-guided laser ablation technology. A less invasive procedure can result in more comfort for you.
In the operating room, your surgeon will create a very small hole (3.2 mm) in your skull, through which a laser cathether is delivered to reach the brain tissue that needs to be treated. Your surgeon will perform the laser placement through a so-called stereotactic procedure, where scans of the brain are used to allow surgeons to pinpoint exactly the area of the brain that needs treatment. Once the catheter is in place, the procedure continues under MRIguidance. Laser energy is delivered to the targeted brain tissue to heat it up and destroy it. Your surgeon can control the amount and duration of laser energy that is delivered to the tissue because he is monitoring real-time MRI images. The MRI images show tissue temperature changes and to what extent the tissue is affected. Additionally, temperature safety limits can be set to protect critical brain structures. This allows the diseased tissue to be destroyed with a high level of precision and control, leaving healthy tissue intact.1-5
