Ventricular volume in infantile hydrocephalus and its relationship to intracranial pressure and cerebrospinal fluid clearance before and after treatment. A preliminary study.
The present study examines ventricular volume before and after shunting in 16 infants with hydrocephalus and mixed aetiology and relates this parameter to rates of cerebrospinal fluid clearance, intracranial pressure and outcome. Following treatment all patients showed reduction in intracranial pressure and amelioration of the clinical manifestations of hydrocephalus. Nevertheless, 4 patients showed persistence of marked ventriculomegaly, 4 had moderate ventricular enlargement, while 8 showed small or normal ventricles. Although the series was small there appeared to be a clear correlation between persistent ventriculomegaly, poor cerebrospinal fluid clearance and poor outcome despite reduction in intracranial pressure. The question is raised as to whether pressure-determined cerebrospinal fluid drainage provides optimum treatment of hydrocephalus in infants given the particular physical characteristics pertaining to the non-rigid cranium.
