Infusion Studies for the Detection of VP Shunt Dysfunction

Subspecialty: Hydrocephalus

Type: Clinical Summary

Educational content sponsored by Joint Operations, the official distributor of LiquoGuard 7: Shunt infusion studies are minimally invasive, bedside tests that force fluid through a ventriculoperitoneal system to characterise cerebrospinal fluid dynamics and determine whether a shunt is functioning, underdraining, overdraining or obstructed; they are based on measuring baseline and plateau intracranial pressure waveforms, pulse amplitude and calculated resistance and comparing these with the shunt’s manufactured operating characteristics. This review reports a large single-centre experience, th…
