Low-pressure CSF shunt malfunction is a poorly understood complication of hydrocephalus affecting patients of all ages. Treatment commonly requires external drainage of CSF to subatmospheric pressures for days to weeks in an intensive care setting. The current communication describes the repurposing of an established therapeutic technique, epidural blood patch, for successful initial management in 2 cases of low-pressure shunt malfunction in the absence of a recognized spinal CSF fistula. This technique may shorten length of stay and obviate potential morbidity in the management of what is otherwise a vexatious clinical problem.
