Ultrasonographic Surveillance of Perinatal Fetal and Neonatal Brain Damage and Intracranial Hemorrhage / 中华围产医学杂志

ABSTRACT

Objective To early diagnose fetal and neonatal brain damage and intracranial hemorrhage resulted from perinatal hypoxia ischemia. Method From April 1987 to April 1999, the brain of 880 high risk neonates delivered were examined by high resolution ultrasound equipment. The fetal brain were observed carefully at prenatal ultrasonography for high risk fetus. Results There were 365 cases of abnormal ultrasound findings (41.5%). Among which 110 cases were found to have hypoxic-ischemic encephalopathy (HIE), (including brain edema or periventricular echodensities), 233 cases of intracranial hemorrhages (among them six cases were detected in uterus and confirmed after birth.), 7 cases of hydrocephalus (two cases detected in uterus), 2 cases of congenital callosal agenesis (one case detected in uterus), one case of cerebral tumor and others 12 cases. The morbidity of intracranial hemorrhage was obviously higher in the neonates of small for gestational age or with pregnant complications. Conclusions Because it is useful for early diagnosis, proper management, and prediction for prognosis, cranial ultrasonography should be done routinely for high risk fetus and neonate.
