A definition of "Hydrocephalus not completely arrested" is not easy to be given. Cerebral pneumography represents the most detailed neuroradiological examination. In spite of this, neither its analysis nor its measurements bring definite criteria for the favorable moment of locating a shunting system in that case. ⋯ It may be but one good reason for explaining the annual decrease in the number of pneumo-encephalographies (PEG) registered almost everywhere in the world. Other factors may be involved. No doubt that PEG has lost its first place in the study of patients who may have some kind of non tumoral hydrocephalus.

Authors report on a series of ten ventricular-cardiac or peritoneal derivations performed under operative field isolation, air-tight and sterile enclosure that makes possible to perform surgery under strict aspsis. The first results compared with those mentioned in the medical literature, let foresee a fall in the occurence of post-operative infections. The technique is adaptable to neurosurgery and does not complicate the operative process.
