【摘要】 笔者报道应用CT对152例围产期窒息儿进行头部扫描,发现缺氧缺血性脑病者128例,阳性率84.21％。本文就其CT表现,CT显示的脑损伤程度与窒息程度的关系以及脑损伤程度与预后的关系进行讨论。从CT表现上将脑损伤程度分为轻、中、重三度。对其病理基础、CT诊断及鉴别诊断的价值亦作了论述。更多还原

【Abstract】 This paper reports the results of our application of head CT scanning to 152 asphyxial perinatal neonates. Among them, there are 128 cases of hypoxic ischmic encephalopathy, a positive rate of 84.21%. on the CT images of that disease, there are diffuse asymmetric low densities around the ventricles;vague or no distinction between the grey and white parenchyma; the vantricles were oppressed and narrowed; and even intracranial hemorrhage in severe patients. The pathologic bases have brain edema and infarction. According to its abnormal changes, we divide it into three degrees on CT images. Clinically serious neonatal asphyxia corralates with moderate or severe CT changes, with poor prognosis and little improvements on the follow-up CT findings. The CT re-examination should be made after two months.更多还原
