CT机在足月新生儿缺氧缺血性脑病的诊断及预后评估的价值

The value of diagnosis and predicting prognosis of hypoxic-ischemic encephalophathy in full-term neonates by CT

目的分析足月新生儿缺氧缺血性脑病(HIE)的CT表现,对其预后进行早期评估。资料与方法选择51例足月HIE患儿,初次CT检查为3-16天,生后1月-2岁6月复查,51例均行1-4次CT复查。结果CT诊断HIE程度越重,发生后遗症的概率越高。轻度预后好,重度预后差,中度部分患儿遗留后遗症。HIE合并颅内出血比率较高,以蛛网膜下腔出血最多见,很少遗留后遗症改变。结论出生后3-16天CT检查,通过观察病灶的形态、范围、密度及有否合并脑出血等方面,为临床对HIE早期治疗提供重要参考,生后1月复查脑CT对评估预后具有重要价值。

Objective To study CT feature and its diagnosed value in full term neonates Materials and Methods The study included 51 cases of full - term neonates with HIE. The initial cranial CT scanning was performed within 3 - 16 days, checked after 1 month - 2 year 6 month Fifty - one cases were observed by CT follow- up one or four times. Results The more severer of the change in CT , the higher occurrence of sequelae would be . The prognosis of the mild lesion was quite good and the prognosis of the severe lesion was a little bad. Tere were the prognosis in some of the moderate lesion. There was a high rate with intracranial hemorrhage and mostly showing subarachnoid hemorrhage. Its prognosis was quite good . Conclusion CT signs was as a important reference for early treatment, by testing the lesion＇ s shape , the extant and density as well as the presence or absence of infracranicl hemorrhage within 3- 16days after birth. There was a important value for evaluation of the prognosis of HIE by CT on 1 month after birth.
