| 目的 分析儿童缺血缺氧性脑病(HIE
)后遗的MRI表现与妊娠时间及临床的关系。方法 搜集33例HIE后遗病例
,按早产儿及足月儿两组分析。结果 ①两组临床症状无差异,一般为运动
障碍、智力障碍、视力异常或抽搐;②早产儿缺血缺氧性脑病后遗MRI一般是脑室旁白质软化
灶(PVL),足月儿多为PVL伴皮层损伤或仅皮层损伤;早产儿PVL程度较足月儿重;③两
组运动障碍和智力落后均与脑白质减少程度相关;智力落后还与胼胝体发育不良程度相关。
结论 HIE后遗改变与妊娠时间和临床症状密切相关。 |

| Purpose To study the relationship between MRI and clinical p
rofiles of the sequelae of hypoxicischaemic encephaemia (HIE) in children. [WTHZ
]Methods [WTBZ]The clinic and MRI findings of 33 cases of HIE were retrospect
ively analyzed. Results ①The major disabilities of the two groups we
re similar: motor and mental retardation, visual impairment or seizure. ②The MRI
abnormalities in the preterm born children were mainly periventricular leukomalacia (
PVL), while in the children born at term were mainly cortical lesion and subcortical
leukomalacia w
ith or without PVL. Periventricular hyperintensity on T2WI was severe in the pre
term-group than that in the term-group. ③The degree of reduction of periventricular w
hite matter correlated with mental retardation and motor impairment in all child
ren. The thinning of the corpus callosum also correlated with mental retardation
. Conclusion The gestational age an
d clinical manifestation of HIE were closely related to the findings of MRI in these cases. |
