Clinical Experience with a New Flow-Regulating Hydrocephalus Shunt System
To date, most shunt systems for surgical treatment of hydrocephalus are differential pressure valves with fairly constant resistance. The amount of cerebrospinal fluid (CSF) drained by these systems varies widely following variations of differential pressure. Particularly when the patient is in an upright position, differential pressure increases extremely, leading to considerable overdrainage of CSF (siphon effect). Overdrainage of CSF may cause clinical manifestations such as slit ventricles and subdural effusions.
