Basilar artery flow velocities and optic nerve sheath diameter as adjuvant tools for early diagnosis of hypoxic ischemic encephalopathy in neonates.

Mean value of left-and-right-optic nerve sheath diameter measurements in control group (0.31 cm, 0.30 cm, respectively) were significantly higher than asphyxiated-group (0.35 cm), with p-value<0.001.

Resistive index (resistive index) of basilar artery decreased and EDV of basilar artery increased in HIE-patients than healthy-control-neonates, with p value<0.001.

Left-and-right-ONSD diameters are negatively correlated with BA-RI, with r=-.432; p < .01and r=-.34; P.046, respectively.
