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
Objective To investigate the CT diagnosis and differential diagnosis of neonatal hypoxic-ischemic encephalopathy (HIE). Methods Fifty-five cases with definite history of perinatal asphyxia and clinical symptoms were analyzed with CT scan and complete clinical and CT diagnostic data. Results Combined with the clinical index and CT indexing, we can see that CT classification and clinical manifestations have some differences. Subarachnoid hemorrhage is the most common complication, and the lesion density, that is, the change of CT value, is significantly different from the normal part. Conclusion CT diagnosis of HIE should be closely combined with clinical data to understand the anatomy of newborns in order to make the right diagnosis
