But seldom studies focus on these preterm neonate’s hemodynamics changes during 72 hours after birth and the adverse short-term outcomes. The present study is planned to assess the parameters of middle cerebral arteries and associate the short-term outcome at 37 weeks early term age in pregnancies complicated by preeclampsia. Methods: A total of 114 preterm neonates were included. The Doppler cranial ultrasound was performed to bilateral middle cerebral arteries within 12 - 24 hours, 36 - 48 hours, 60 - 72 hours after birth for all the eligible study neonates. The parameters of resistive index (RI), resistive index (PI) and middle cerebral velocity (MBFV) were recorded by Doppler cranial ultrasound and 106 infants survived assessed by the Neonatal Behavioral Neurological Assessment (NBNA) at 37 weeks early term-equivalent age. Results: There were a total of 106 subjects that finally completed the NBNA examination at 37 weeks of early term-equivalent age. In the surviving infants, there were a total of 26 infants with abnormal NBNA scores, among them, 12 infants’ mothers were diagnosed with preeclampsia, accounting for up to 46.1%. In these preterm neonates, the lower velocity of bilateral middle cerebral arteries was observed in abnormal infants (p Conclusion: Velocity of middle cerebral artery is significantly abnormal in preeclampsia. The slower velocity in the 72 hours after birth, the higher associated with adverse perinatal short-term outcome.展开更多

Results showed that corpus callosum length as well as thickness of the genu and splenium increased with gesta- tional age and birth weight, while other measures did not. These three factors on the standard mid-sagittal plane are therefore likely to be suitable for real-time evaluation of corpus callosum de- velopment in premature infants using cranial ultrasound. Further analysis revealed that thickness of the body and splenium and the anteroposterior diameter of the genu were greater in male infants than in female infants, suggesting that there are sex differences in corpus callosum size during the neonatal period. A second set of measurements were taken from 40 premature infants whose ges- tational age was 34 weeks or less. Corpus callosum measurements were corrected to a gestational age of 40 weeks, and infants were grouped for analysis depending on the outcome of a neonatal behavioral neurological assessment. Compared with infants with a normal neurological assessment, corpus callosum length and genu and splenium thicknesses were less in those with abnormalities, indicating that corpus callosum growth in premature infants is associated with neurobehavioral development during the early extrauterine stage.展开更多

We report a case of a full-term neonate from vaginal birth with caput succedaneum in the right parietal area. The neonate underwent cranial ultrasonography and color Doppler which showed extra-axial blood effusion. Color Doppler showed vessels crossing the collection area, which allowed the diagnosis of subarachnoid hematoma.展开更多
