[Arrested shunt-independent hydrocephalus].

Analysis of 102 children ventriculo-vascular shunted in infancy from 1958-71 reveals the existence of an arrested shunt-independent hydrocephalus (a.s.h.). 13 suspected cases have been selected by routine examinations and by the so-called retrospective longitudinal examination. The diagnosis of arrested shunt-independent hydrocephalus was made in 7 and discarded in 6 as follows: repeated work-ups, shunt ligature and removal and year-long follow-up examinations using a broad spectrum of tests to evaluate the hydrocephalus. The particular analysis of the 13 children contributes to significant findings concerning incidence, aetiopathogenesis and differential diagnosis of a.s.h.
