Neonatal cerebral color doppler duplex imaging in moderate hypoxic ischemic encephalopathy

ABSTRACT

The aim of this study was to evaluate the neonatal cerebral blood flow velocity changes in moderate hypoxic ischemic encephalopathy [HIE] using color Doppler duplex ultrasound. Fifteen full term asphyxiated newborn infants with moderate HIE were examined prospectively using transfontanel color Doppler duplex ultrasound with 5 mHz curvilinear probe. Fifteen full term age and weight matched healthy newborn infants were also examined as a control group. The results showed a significant reduction in the mean values of peak systolic velocity [PSV], end diastolic velocity [EDV] and mean flow velocity [MV] in anterior cerebral artery [ACA] in newborn infants with HIE than those of the control group. The PSV, EDV and MV values in middle cerebral artery [MCA] were significantly lower than that of the control group. Doppler duplex ultrasound is noninvasive imaging modality to evaluate cerebrovascular dynamics in newborn infants with HIE
