新生儿颅内出血与缺氧缺血性脑损伤的CT诊断研究

报告138树新生儿颅内出血和缺氧缺血性脑损伤。在分析发病机理与CT表现之间关系的基础上，提出不能将颅内出血和缺氧缺血性损伤绝对割裂开来，也不能将所有新生儿颅内损伤都归入缺氧缺血性脑病（HIE）。建议以缺氧缺血性脑损伤（HID）来表达CT图像上的病理性低密度改变，避免与HIE混淆。另外作者认为脑水肿是HIE的一种早期表现，可为局限性，也可为弥漫性；可发展为坏死、出血，也可逆转消失。

CT Diognosis in Differentiation of Intracranial Hemorrhage and Hypoxic Ischemic Damage of the Brain in Neonates

This article reported the CT findings in 138 cases of intracranial hemorrhage and hypoxic ischmic damage of brain(HID) in neonates. The features were analysed on the basis of etiology. The author proposed that intracranial hemorrhage was not disconnected with hypoxic ischmic damage,and hypoxic ischmic encephalopthy (HIE) didnot contain all kinds of neonatal intracranial damage,and he also suggested that the pathologic hypodense changes in CT pictures deserrel to be discribed as HID,it was helpful to differentiate HID from HIE. It is stressed that brain edema is the early sign of HIE,it may be local or diffuse. Its outcome may either disappear to recovery or further develop into necrosis.
