小于胎龄儿由于其患病率及病死率均明显地高于适于胎龄儿,因此在围产医学的防治、降低新生儿的发病率及死亡率方面均有重要意义。有关小于胎龄儿的诱发因素及临床分析,国内、外均有报道。本文仅对66例曾作颅脑CT扫描者的CT改变与临床资料进行分析,探讨小于胎龄儿与脑损伤的关系。 Because of their morbidity and mortality, children younger than gestational age are significantly higher than those who are suitable for gestational age. Therefore, it is of great significance in the prevention and treatment of perinatal medicine and in reducing the morbidity and mortality of newborns. For less than gestational age children induced factors and clinical analysis, both at home and abroad have been reported. In this paper, only 66 cases of CT scan of brain CT scan and clinical data were analyzed to explore the relationship between less-gestational age children and brain injury.
