Cerebral edema due to perinatal asphyxia in 2 full-term newborns was detected and monitored with a combination of real time ultrasound, computed tomography, and serial pulsatility-index determinations of the cerebral arteries using Doppler ultrasound. In both babies, real time ultrasound showed small or slitlike lateral ventricles, an increase in diffuse echogenicity and obliteration of normally visible structures in the acute phase suggesting cerebral edema. In the recovery phase a remarkable widening of the ventricles was seen. We also found a relationship between disturbances of consciousness (probably due to cerebral edema) and the pulsatility index. The combination of serial pulsatility-index determinations of the anterior cerebral arteries and real time ultrasound of the brain may in the future be a useful "bedside" method for early detection and follow-up of the cerebral edema.
通过实时超声、计算机断层扫描以及使用多普勒超声对脑动脉进行连续搏动指数测定相结合的方法，对2例足月新生儿围产期窒息所致的脑水肿进行了检测和监测。在这2例患儿中，实时超声均显示侧脑室小或呈裂隙状，急性期弥漫性回声增强，正常可见结构消失，提示脑水肿。在恢复期可见脑室明显增宽。我们还发现意识障碍（可能由脑水肿引起）与搏动指数之间存在关联。未来，大脑前动脉连续搏动指数测定与脑部实时超声相结合可能成为早期检测和随访脑水肿的一种有用的“床边”方法。
