Cerebrospinal fluid shunt or device-associated infection are rare but with a high mortality rate. Mortality was more closely related to the infection than to comorbidity or underlying neurosurgical disease. A second CSF analysis significantly helped to detect patients with device-associated infections with a poor prognosis 1)
Childrens with shunt infections have an increased mortality rate and risk of seizure than those without shunt infection. Those with myelomeningocele who develop ventriculitis after shunting have a lower IQ compared to those without infection 2).
Mortality ranges from 10-15 %.
