螺旋CT检查在新生儿缺血缺氧性脑病中的应用

Application of spiral CT examination in neonatal hypoxicischemic encephalopathy

目的探讨新生儿缺血缺氧性脑病（hypoxie—ischemicenceph—alopathy，HIE）的螺旋cT表现特点及其应用价值。方法回顾性分析60例HIE的cT表现，依据病灶范围观察轻度至重度HIE的cT表现特征。结果60例临床诊断为HIE的患者中54例有异常cT表现，6例未见异常。5l例病变cT值在10^，18HU之间，3例病变cT值在18～21HU之间。脑实质出血1例，蛛网膜下腔出血者4例。复查外部性脑积水4例，脑软化5例、脑萎缩1例。结论螺旋cT检查对HIE的诊断具有较高的准确性。

Objective To investigate the spiral CT performance features of neonatal hypoxic-ischemic encephalopathy （HIE） and its application value. Methods The CT performance of 60 patients with HIE was analyzed retrospectively and the CT performance features of mild to severe HIE were observed according to the lesion range. Results Of the 60 patients clinically diagnosed with HIE, 54 patients had abnormal CT performance and 6 patients did not. Fifty-one patients had a CT value ranging from 18-21I-IU. Brain parenchyma bleeding was found in 1 patient and subarachnoid hemorrhage was found in 4 patients. Reexamination found external hydrocephalus in 4 patients, encephalomalacia in 5 patients and cerebral atrophy in 1 patient. Conclusion Spiral CT examination is accurate in the diaznosis of HIE and can provide true and objective basis for clinical treatment and prognosis.
