Aim Posthaemorrhagic ventricular dilatation (PHVD) is monitored by conventional two‐
dimensional ultrasound (2 DUS). The aims of this study were to determine the volume of the
lateral ventricles using three‐dimensional ultrasound (3 DUS) in preterm infants with PHVD

Aim
Posthaemorrhagic ventricular dilatation (PHVD) is monitored by conventional two‐dimensional ultrasound (2DUS). The aims of this study were to determine the volume of the lateral ventricles using three‐dimensional ultrasound (3DUS) in preterm infants with PHVD and to evaluate the relationship between volume and linear measurements.
Methods
Serial 2DUSs and 3DUSs were performed on preterm infants with PHVD admitted to the neonatal intensive care unit at Puerta del Mar Hospital, Cádiz, Spain, from January 2013 to December 2014. The ventricular index, anterior horn width and thalamo‐occipital distance were used as ventricular lineal measurements. Ventricular volume was calculated offline.
Results
Serial ultrasounds from seven preterm infants were measured. Each linear measurement was significantly associated with volume, and an equation was obtained through a significant multilevel mixed‐effects lineal regression model: ventricular volume (cm3) = −11.02 + 0.668*VI + 0.817*AHW + 0.256*TOD. Intra‐observer and interobserver agreement was excellent with an intraclass correlation coefficient of 0.99.
Conclusion
Lateral ventricular volumes of preterm infants with PHVD could be reliably determined using 3DUS. Ventricular volume could be accurately estimated using three lineal measurements. More studies are needed to address the importance of volume determination in PHVD.
