新生儿缺氧缺血性脑病CT诊断与随访 (pdf)[摘要] 目的 讨论新生儿缺氧缺血性脑病(NAE)的CT诊断与随访。方法 对56例NAE患儿进行头颅CT平扫，分析CT征象。结果 16例诊断为轻度NAE，表现为大脑实质内有斑片状低密度灶，范围≤2个脑叶；23例诊为中度NAE，病灶分布超过2个脑叶，脑回白质分界不清，其中11例并发蛛网膜下腔出血；17例为重度NAE，大脑半球呈弥漫低密度，脑室、脑池变窄或消失，其中6例合并脑内出血，随访30例，CT显示11例恢复正常，3例脑白质萎缩，4例脑积水，7例脑灰质萎缩，2例遗留脑软化灶，3例双额部有少量硬膜下积液。结论 CT除能准确诊断NAE外，还可用于随访观察其后遗症。

[Abstract] Objective To evaluate the CT diagnosis and follow-up study of anoxemic amxenuc encephalopathy in neonates.Methods The CT features of 56 cases of hypoxic ischemic encephalopathy in neonates were studied.Results Mild degree of encephalopathy was found in 16 cases showing a low-density patch with a size not exceeding 2 lobes.The pathological changes were moderately advanced in 23 cases.The size of the diseased patch exceeded 2 lobes and its margin was blurred.There was subarachnoid hemorrhage in 11 out of the 23 cases.Severe manifestations of encephalopathy occurred in 17 cases.Low-density patch extended over the cerebral hemisphere and the ventricle and cisterna were narrowed or even disappeared.Intracerebral bleeding occurred in 6 out of the 17 cases.Follow up observation of the 30 cases with CT revealed:recovery to normal in 11 cases,white matter atrophy in 3 cases,hydrocephalus in 4 cases,gray matter atrophy in 7 cases,encephalomalacia in 2 cases,a small amount of subdural effusion of both sides in 3 cases.Conclusion In addition to the diagnosis of hypoxic-ischemic encephalopathy,CT can also discover the sequelae of the disease. ......
