Hemodynamics of infants with strong fluctuations of internal cerebral vein

There is a high incidence of intraventricular hemorrhage in extremely low‐birthweight (ELBW) infants of low gestational age with high‐grade fluctuations in the perfusion waveform of the internal cerebral vein. This study investigated changes in the hemodynamic status of ELBW infants during initial strong fluctuations in the perfusion waveform of the internal cerebral vein.
