title: Radiological findings in relation to the neurodevelopmental outcome in hydrocephalic children treated with shunt insertion or endoscopic third ventriculostomy.
abstract: OBJECTIVE
  The aim of the study was to compare the radiological indicators of effectiveness for hydrocephalus treatment in children operated on under the third year of age with the use of shunt insertion (SI) and endoscopic third ventriculostomy (ETV). The effectiveness was considered in terms of postoperative neurodevelopment in correlation to pre- and postoperative radiological findings.
  
  
  METHODS
  The examined group consisted of 46 children operated on for hydrocephalus in the Division of Pediatric Neurosurgery in Katowice, Poland. There were 21 children treated with SI and 25 with ETV. The radiographic assessment was carried out on the basis of MRI and CT examinations with the use of a linear estimate known as frontal and occipital horn ratio (FOR). The FOR values were calculated for the entire group and in correlation to the treatment method and to the children neurodevelopment evaluated with The Denver Developmental Screening Test.
  
  
  RESULTS
  No differences were recognized between initial FOR value in terms of the postoperative children neurodevelopment. In the successful ETV-treated subgroup, the mean change in FOR was 0.05 and in the SI-treated subgroup, the mean change in FOR 0.13. The patients with BFOR >0.1, developed normally more often than those in whom BFOR was lower than 0.1.
  
  
  CONCLUSIONS
  The initial FOR value probably does not affect the postoperative developmental outcome. Long-term change in ventricles size after surgery can correlate with psychomotor development of hydrocephalic children. Presumably, there are no differences between two treatment options according to initial FOR values and to changes in FOR values.
