Fibrin sealant to prevent subdural electrode migration during intracranial electroencephalographic monitoring in a patient with a large arachnoid cyst.

ABSTRACT

Ensuring a stable position of intracranial electrode grids with good proximity to the cortical surface can be a technical challenge in patients with complex anomalous cerebral anatomy. This report illustrates the use of fibrin sealant to secure subdural electrodes to concave cortical surfaces during intracranial electroencephalographic monitoring for localization-related medically intractable epilepsy in a patient with a large arachnoid cyst.
