Acquired hydrocephalus. V. Determination of the formation rate of albumin in the ventricular system.

By quantitative isotope ventriculography (QIV), the formation rate of albumin in the ventricular system (FRalb) was determined in 14 hydrocephalic and 14 nonhydrocephalic patients. The FRalb was significantly reduced in the patients with acquired hydrocephalus. By a comparison of the mean formation rate of albumin (MFRalb) and the mean absorption rate of albumin (MARalb), a significant biological difference in the two groups of patients was demonstrated.
