螺旋CT临床评价新生儿缺血缺氧性脑病

目的 :通过螺旋CT临床评价新生儿缺血缺氧性脑病的颅内特征。方法 :对 72例临床诊断为脑缺血缺氧性脑病的新生儿进行头颅螺旋CT扫描 ;随机选择 30例正常新生儿的头颅螺旋CT扫描作对照。结果 :新生儿缺血缺氧性脑病的临床表现与螺旋CT征像基本一致。螺旋CT征像主要包括三种形式 :①轻度的脑白质水肿 ;②中度的脑水肿和脑实质内出血 ;③脑实质水肿和出血 ,合并颅内脑外出血。结论 :螺旋CT头颅检查对新生儿脑缺血缺氧性脑病的临床分度有重要意义。

HypoXic-ischemic encephalophathy of newborn: clinical assessment with spiral CT

Objective: To assess clinically the usefulness spiral CT imaging in the detection of hypoxic_ischemic encephalopathy in newborns. Materials and Methods: Seventy_two HIE of neonates who underwent spiral CT examination were studied. Thirty normal neonates who undernent spiral CT examination were selected randomly. Results: Neonatal clinic findings were directly related with spiral CT findings: Spiral CT findings contained three typs:(1)little white matter edema. (2)mild white matter edema and intraparenchymal hemorrhage.(3)Sever white matter edema and intraparenchymal hemorrhage complicated with extraaxial hemorrhage. Conclusion:Sprial CT is important in the detection of neonatal hypoxic_ischemic encephalopathy.
