Objective: Chronic intracranial hypertension is present in up to 20% of children with non-syndromal craniosynostosis. Our aim was to assess the relationship between the lumbar pressure values and blood flow velocities assessed by Transcranial Doppler sonography (TCD) in children with scaphocephaly.
Methods: In 22 children with scaphocephaly, the lumbar pressure was assessed by manometer preoperatively and the TCD examination was performed. TCD was repeated on day 7 or 8 after the surgery. Index of pulsatility (PI) and resistance index (RI) were obtained and compared pre- and postoperatively. The correlation of TCD indexes and lumbar pressure values was assessed.
Results: In 17 children, the lumbar pressure values were higher than normal, in a subgroup of older children (>6 months) the LP pressure values were significantly higher (p<0,05). The difference in PI and RI indexes was not significant. No significant correlation was found between TCD parameters and intracranial pressure.
Conclusions: In patients with scaphocephaly, there is higher prevalence of raised lumbar pressure; the risk of intracranial hypertension development may be increased in older children. TCD is not useful in the diagnosis of intracranial hypertension in craniosynostosis.
