Complications of invasive monitoring used in intractable pediatric epilepsy.
Invasive monitoring for intractable epilepsy is useful when the epileptogenic focus is in question even after an extensive noninvasive presurgical evaluation, or when the epileptogenic focus is located in or near eloquent cortex. From June 1989 to June 2001 at the Children's Hospital of Philadelphia, 64 children with intractable epilepsy underwent 67 invasive monitoring procedures as part of their presurgical evaluation. The average age at implantation was 10 years. ⋯ One patient did have a transient visual field loss after placement of an occipital grid. While CSF leaks are common after invasive monitoring despite precautions, clinically significant CSF infections are uncommon and appear to be unrelated to the duration of monitoring, the occurrence of a CSF leak or the length of time the patient is on perioperative antibiotics. We conclude that invasive monitoring for intractable epilepsy is generally safe.
