新生儿缺氧缺血性脑病CT诊断和随访价值

目的讨论新生儿缺氧缺血性脑病的CT诊断和随访价值.方法对56例缺氧缺血性脑病患儿行头部CT平扫,分析CT征象.结果 12例CT诊断为轻度HIE,表现为大脑实质内有斑片状低密度灶,范围≤2个脑叶;26例诊断为中度HIE,病灶分布超过2个脑叶,其中10例合并颅内出血.18例诊断为重度HIE,大脑半球呈弥漫性低密度,脑室、脑池变窄,其中8例合并颅内出血.随访32例,7例恢复正常,12例脑萎缩,5例脑积水,3例遗留脑软化灶,5例双额少量硬膜下积液.结论 CT能准确诊断HIE,还可用于随访观察其后遗症.

CT diagnosis and follow-up observation for hypoxic-ischemic encephalopathy in neonates

Objective To evaluate CT diagnosis and follow-up study of hypoxic-ischemic 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 12 cases showing a size not exceeding 2 lobes.The pathological changes were moderately advanced in 26 cases.The size of the diseased patch exceeded 2 lobes.There was subarachnoid hemorrhage in 10 out of the 26 cases.Severe manifestations of encephalopathy occurred in 18 cases.Low-density patch extended over the cerebral hemisphere and the ventricle and cisterna were narrowed.Intracerebral bleeding occurred in 8 out of the 18 cases.Followup observation with CT revealed recovery to normal in 7 cases,matter atrophy in 12 cases,hydrocephalus in 5 cases,encephalomalacia in 3 and small amount of subdural effusion of both sides in 5.Conclusion In addition to the diagnosis of hypoxic-ischemic encephalopathy,CT can discover the sequel of the disease.
