We have performed serial trans-fontanelle sonography on 69 newborns with perinatal asphyxia. Ten neonates presented high ultrasonic density in the thalamus and the basal ganglia. These images were preceded, in eight of them, by diffuse echoes for all of the CNS, corresponding to cerebral edema. The most significant clinical findings were convulsions and important depression of conscience level and muscular tone. Eight of ten newborns presented major abnormalities in the electroencephalogram (severe depression of background). Since its coexistence with other parenchymal lesions and poor neurologic development, we consider the ganglio-thalamic ultrasonic densities to be a sign of severe ischemic hypoxic cerebral damage.
我们对69例围产期窒息的新生儿进行了系列经囟门超声检查。10例新生儿丘脑和基底神经节出现高超声密度。其中8例在这些图像出现之前，整个中枢神经系统出现弥漫性回声，提示脑水肿。最显著的临床发现是惊厥、意识水平和肌张力明显降低。10例新生儿中有8例脑电图出现严重异常（背景活动严重抑制）。鉴于其与其他实质病变并存以及神经发育不良，我们认为丘脑 - 基底神经节超声密度是严重缺血缺氧性脑损伤的一个征象。
