超声对新生儿缺氧缺血性脑病的诊断价值

Value of ultrasound in diagnosing neonatal hypoxic-ischemic encephalopathy

目的评价超声诊断新生儿缺氧缺血性脑病(HIE)的临床价值。方法新生儿HIE39例,10例健康足月新生儿为对照组,超声对比观察其颅内声像图改变。结果 39例新生儿HIE,轻度10例,3例合并室管膜下囊肿,1例合并脉络丛囊肿;中度8例,4例合并室管膜下囊肿,3例合并室管膜下出血;重度21例,合并4例脑实质出血,2例室管膜下出血,2例侧脑室内出血伴脑室扩张。结论超声可较清楚显示新生儿颅内结构,对HIE诊断准确性较高,且可进行动态观察,对HIE的病情及预后进行估测,有较好的临床价值。

Objective To evaluate the clinical value of ultrasound in diagnosing neonatal hypoxic-ischemic encephalopathy （HIE）. Methods Thirty-nine HIE cases and 10 healthy neonate were enrolled. The intracranial image changes were observed by ultrasonography. Results Among the 39 cases, 10 cases were mild HIE. 3 cases had ependyma cysts. 1 case had choroid plexus cyst. 8 cases were moderate HIE. 4 cases had ependyma cysts. 3 cases had ependyma bleeding. 21 cases were severe HIE .4 cases had craniocerebral bleeding. 2 cases had ependyma bleeding. 2 cases who had lateral ventricle bleeding and enlarged ventricle. Conclusion Ultrasound can clearly display the encephalic structure of neonate, it has high diagnostic accuracy and good clinical value for dynamically observing and assessing the state and prognossis of HIE.
