Changes of head circumference and ventricular width in infant hydrocephalus managed with adjustable shunt valves and gravitational assistance—a comparative bi-center study

The present study demonstrates a strong relation between changes in median FOHR and head circumference at the end of follow-up in shunted hydrocephalic infants. In addition, we identified a direct influence of initial valve setting on changes of ventricular width and head circumference at follow-up, underlining the importance of valve resistance for regulating CSF diversion and its anatomical consequences. Further investigations are needed to assess the influence of these parameters on long-term neurodevelopment and functional outcome.
