Cerebrospinal fluid oedema: a rare complication of the ventriculo-subgaleal shunt

Abstract

The ventriculo-subgaleal shunt is a useful technique for obtaining a temporary decompression of the ventricles in patients with obstructive hydrocephalus. A direct surgical approach to remove the obstruction can restore the CSF circulation. When the shunt tube is left behind after restoration of the CSF dynamics, an extensive CSF oedema can develop in the white matter along the drain, resulting in a severe clinical syndrome. A possible mechanism is discussed. Quick and adequate treatment proved that the cerebral damage is reversible.
