新生儿缺氧缺血性脑病的CT诊断(附55例分析)

目的　探讨新生儿缺氧缺血性脑病 (简称HIE)的CT诊断及鉴别诊断。方法　对 5 5例有明确围产期窒息史 ,且有临床症状的病例进行CT扫描 ,取得完整的临床及CT诊断资料后加以分析。结果　结合文献进行临床分度及CT分度 ,可见CT分度与临床表现有一定的差异性。蛛网膜下腔出血是最常见的并发症 ,病灶密度即CT值改变与正常部位相比有显著性差异。结论　HIE的CT诊断要密切结合临床资料 ,掌握新生儿的解剖结构特点 ,才能做出正确的诊断

CT Diagnosis of Hypoxic-Ischemic Encephalopathy in Neonates

Objective To study the CT diagnosis and differential diagnsis of hypoxic ischemic encephalopathy (HIE)in neonates.Methods 55 cases who had clear history of asphyxia in perinatal period and had clinical symptoms were scanned with CT.The complete clinical materials and CT data were analyzed.Results The clinical and CT grades were conducted according to references.The results showed that there was difference between CT grades and clinical manifestation.Subarachnoid hemorrhage was the most common complication.The density of the lesions was significantly different from that in normal sites.Conclusion In the CT diagnosis of HIE,clinical data and anatomical structure of neonates are both critical for the correct diagnosis.
