Abstract/OtherAbstract:
Aim  To correlate volumetric magnetic resonance imaging at term with neurodevelopmental outcome at 2 years in infants with post-hemorrhagic ventricular dilatation. Preterm infants with post-hemorrhagic ventricular dilatation have high risk of disabilities but the range is wide and predicting severity of motor and mental disability is difficult. Methods  25 preterm infants with post-hemorrhagic ventricular dilatation had cerebral magnetic resonance imaging at term age. Total and regional brain volumes were calculated using a manual segmentation technique. Bayley Scales of Infant Development II were assessed at 2 years post term. Developmental Quotients (DQ) were calculated from Developmental Age Equivalent scores. Results  Total cerebral volume, excluding ventricles, correlated positively with Motor (r = 0.8, p<0.0001), and Mental DQ (r =0.4,p=0.02). Only 3 out of 16 infants with cerebral volume <336 cm(3) were ambulant at 2 years. Cerebellar volumes correlated strongly with Motor DQ (r=0.6,p=0.002) but only with Mental DQ after adjustment. Thalamic volumes correlated strongly with Motor DQ (r=0.7,p=0.0002). Conclusion  Brain growth is significantly impaired in post-hemorrhagic ventricular dilatation. Volumetric measurements at term of total cerebral and cerebellar volume may have a role in predicting severity of disability. © 2012 The Author(s)/Acta Paediatrica © 2012 Foundation Acta Paediatrica.
