Neurosurgeons at Children's Hospital Colorado use stereoelectroencephalography (SEEG) to identify the source of a child's seizures in their brain. A child may be recommended for SEEG when their seizures don't respond to medicine or other treatments, and other tests suggest that the seizures are coming from a single area of the brain.
SEEG is a minimally invasive procedure that uses sophisticated technology to implant up to 20 electrodes (0.8mm in diameter) through small holes in the skull (about the width of a piece of spaghetti) into the tissue of the brain.
The electrodes monitor a child's seizures and help pinpoint where they begin. Once the source is located, the electrodes are taken out. Your child's doctor then may recommend surgery to remove the identified tissue.
The neurosurgeons in our Neuroscience Institute use a state-of-the-art surgical tool called a robotic operating surgical assistant (ROSA) to perform SEEG and other brain surgeries and procedures.
By using ROSA's sophisticated software, our surgeons can perform operations more precisely and quickly due to the advanced image-guided surgical planning.
Your child's care team helps both you and your child get ready for the procedure. Our neurosurgeons explain what SEEG is in an age-appropriate manner, which helps the whole family understand what to expect.
Once your child is admitted to Children's Colorado on the day of their surgery, they may have a CT study (also known as a CAT scan) and additional lab work completed. Families also meet with a pediatric anesthesiologist to learn about the sleep-like state that keeps your child pain-free during the procedure.
Patients keep the SEEG electrodes in until a seizure(s) is recorded (usually one week). The team may also send electricity into the electrodes to map out the functions of nearby brain areas. As soon as the epilepsy team has the information they need, the electrodes are removed, which is a quick procedure.
Our epilepsy specialists review the information collected by the electrodes to see if surgery is the right option for your child. Before you leave, your child's care team shares the results with you and provides a recommend action plan.
If epilepsy surgery is suggested, your child will return to the hospital at a later date to discuss the best surgical approach for your child.
Your child may be eligible for SEEG if:
Our Neuroscience Institute is the only children's hospital in the region that is using ROSA and SEEG.
SEEG is a minimally invasive surgical tool that allows neurosurgeons at Children's Colorado to produce more accurate seizure recordings in a shorter amount of time than traditional methods. Our surgical team is always striving to improve the care we provide to children.
According to the National Association of Epilepsy Centers (NAEC), Children's Colorado is a Level IV Epilepsy Center. That means our Epilepsy Program provides the highest quality of care for patients with complex health needs. Our program provides complete care for children with epilepsy from evaluation to surgical treatments.
