[Alterations of skull development in shunt-treated hydrocephalus. Analysis of pathogenic factors (author's transl)]

Skull roentgenograms of 184 children with hydrocephalus treated with shunts were revised. Radiological abnormalities of the skull related to CSF drainage were found in 49,5% of cases. Presence of X-ray abnormalities was correlated with the age of patients at operation, sex, etiology of hydrocephalus, type of shunt device, head circumference at operation and follow-up. Results were submitted to statistical analysis. In this study it is clearly demonstrated that age and head circumference before operation have a strong influence in the pathogenesis of this picture.
