title: [Informativeness of computer tomography and the infusion test in the diagnosis of progressive open internal hydrocephalus].
abstract: Computerized tomography examination showed considerable internal hydrocephalus in 9 patients who were operated on for cerebral aneurysm. To determine in which cases hydrocephalus was progressive and called for operation the authors conducted tomoventriculography with amipaque (metrizamide) in parallel with the infusion test establishing quantitatively the resorption efficiency of the cerebrospinal fluid. The results of the examination allowed the disease to be recognized in 5 patients and diagnosed as progressive internal hydrocephalus which ceased after a decompression (pressure-relieving) valve was implanted. The authors claim tomoventriculography and the infusion test to be valuable in differentiating progressive hydrocephalus from stable hydrocephalus.
