[[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

[[Children]]s with [[shunt infection]]s have an increased [[mortality]] rate and risk of [[seizure]] than those without [[shunt infection]]. Those with [[myelomeningocele]] who develop [[ventriculitis]] after [[shunt]]ing have a lower IQ compared to those without [[infection]]
((McLone D.G., Czyzewski D., Raimondi A.J.Central nervous system infections as a limiting factor in the intelligence of children with myelomeningocele. Pediatrics, 70 (1982), pp. 338-342.)).

[[Mortality]] ranges from 10-15 %.
