Post-haemorrhagic hydrocephalus management: delayed neonatal transport negatively affects outcome.

Post-haemorrhagic ventricular dilatation (PHVD) remains a major cause of brain injury in preterm infants. Cerebrospinal fluid drainage is often needed to decrease dilatation and prevent further damage. Like most European neonatal intensive care units (NICUs), we treat infants once the ventricular index (VI) has crossed the 97th percentile (p97) and 4mm line, as recently recommended.
