新生儿缺氧缺血性脑病的CT评价(附66例分析)

CT Evaluation of Hypoxia and Ischemic Encephalopathy in Newborn

目的：提高新生儿缺氧缺血性脑病（HIE）的CT早期诊断丰。材料与方法：收集HIE66例，首次CT检查时间在2小时至13天，其中14例在7天至12天做了复查，1例在4月和13月后做了复查。结果：①所有病例脑内均出现了低密度灶（＜18Hu）。②蛛网膜下腔出血（SAH）的发生率为38／66。③低密度灶出现的越广泛，SAH的发生率越高。④临床上有窒息和抽搐史的新生儿，其低密度区的范围大，SAH的发生率高。结论：CT是目前诊断HIE的最佳检查方法。

Purpose: Increase the eary diagnortic detectable rate of hypoxia and ischemic encephalopathy (HIE) in newbom.Metetich and Metbods: Collected 66 cases of HIE. The First CT scanming time were during 2h to 13d. 14 cases were made reexamination during 7d to 12d. one case was made the twice reexamination in 4m and 13m. ResultS: ①All cases display the hypldense region (<Hu) in brain. ②The incidence rate of the subarachnoid hemorrhage (SAH) was 38/66. ③The more hypodense region were displayed, The more incidense rate of SAH were Observed. ④If the newborns have the asphyctic and convulsive history, the extensive hypodense rngion and high incidence rate of SAH would been found. Conculsion: At present CT is the best way to diagnosis HIE.
