CT diagnosis of premature infant hypoxic ischemic encephalopathy :Areport of 28 cases

目的:提高对早产儿缺氧缺血性脑病CT表现的认识。方法:对28例临床诊断为早产儿缺氧缺血性脑病的患儿进行CT检查,并对其图像进行分析。结果:28例CT均可见脑实质低密度脑水肿病灶;其中轻度14例,合并脑室出血2例,合并蛛网膜下腔出血3例;中度9例,合并蛛网膜下腔出血1例;重度5例,合并脑室出血2例,合并蛛网膜下腔出血1例。结论:CT可以发现早产儿缺氧缺血性脑病时的脑水肿以及颅内出血,并对其进行分度,为临床诊断、治疗及评估预后提供帮助。

Methods：Twenty-eight premature infants diagnosed as HIE were performed using CT scan and their CT images were analyzed. Results：All the 28 cases of HIE showed low density edema area in the brain white matter. Of the 14 minor cases,2 were accompanied by intraventricular hemorrhage（IVH） and 3 by subarachnoid hemorrhage（SAH）; Of the 9 moderate cases, 1 was accompanied by SAIl;Of the 5 sever cases, 2 were accompanied by IVH. Conclusions：The brain edema and intracranial hemorrhage in the premature infant HIE can be detected by CT scan,which is of great be.nefit to the clinical diagnosis and treatment.
