| 摘 要： | 目的：探讨新生儿缺氧缺血性脑病（HIE）临床CT表现和分度的关系。方法：对85例缺氧缺血性脑病新生儿的临床资料及CT征象进行回顾性分析。结果：根据HIE的临床诊断标准，轻度26例，中度38例，重度21例。颅脑CT显示全部85例均具有脑内异常密度减低区，CT值约6～18Hu（平均11Hu）；合并颅内高密出血（52例），CT值约58～85Hu。依据新生儿缺氧缺血性脑病的CT诊断标准：轻度26例，中度38例及重度21例。48例进行了CT复查。其中19例轻度患儿脑水肿均在11天内消失而恢复正常；12例中度病例中，脑水肿征象有不同程度的减轻或消失，蛛网膜下腔出血已吸收，1例出现硬膜下少量积液；17例重度患者，其中出现脑软化6例，硬膜下积液3例，脑萎缩3例，脑积水2例，脑内钙化灶2例，脑穿通畸形1例，死亡4例。结论：本组资料新生儿缺氧缺血性脑病临床诊断分度与CT诊断分度有着很好的一致性。颅脑CT能准确显示HIE患儿脑内病变的部位、范围和程度。CT复查能显示患儿脑内病灶的恢复及遗留病变。颅脑CT表现结合临床分度能对本病的进行早诊断、早干预，减少脑损伤后遗症的发生，有着极其重要的价值。

| Abstract: | Objective:To discuss CT characteristic and clinical manifestation of hypoxic-ischemic encephalopathy (HIE).Methods:Combined with CT manifestation,the clinical materials of 85 HIE patients were analyzed retrospectively.Results:According to the clinical diagnosis criterion of HIE,the patients in this sequence were divided into three groups,mild group(26 cases),moderate group(38 cases),severe group(21 cases).At CT imaging,there was low density area of brain in 85 cases,CT value was from 6 to18Hu,combined with high density hemorrhage of 52 cases,which CT value was about 58 to 85Hu.According to the CT diagnosis criterion of HIE,in three groups(mild,moderate and severe group)were 26,38,and 21 cases,respectively.Out of all cases, 48 cases were performed fellow-up CT examination in latter,19 cases of hydrocephalus in mild group became normal in 11 days,12 cases of the hydrocephalus in moderate group were lightened and disappeared,and subarachnoid hemorrhage were absorbed.A little subdural effusion was appeared in one case.In severe group,out of 17 cases,there was 6 cases of encephalomalacia,3 cases of brain atrophy and subdural effusion,2 cases of waterhead,2 cases of calcification,1 case of porencephalic cyst,4 cases dead.Conclusions:Cranial CT could show the brain lesions of neonatal HIE,according to CT manifestation of HIE,it was consistent with clinical criterion.Re-CT examination could show the change of this cranial disease.Combined with clinical manifestation, the examination of cranial CT has important value for diagnose and intervene,and decrease the sequela of this disease. |
