螺旋CT诊断新生儿缺血缺氧性脑病在基层医院的应用体会

The application of spiral CT in neonatal Hypoxic-ischenic encephal opathy in the basic hospital

目的探讨螺旋CT诊断新生儿缺血缺氧性脑病(HIE)在基层医院的应用。方法回顾分析144例临床拟诊为新生儿HIE病例,其中拟诊缺血缺氧性脑病75例,合并其他疾病69例,行螺旋CT诊断及治疗后复查。结果144例CT发现脑内低密度影,呈局灶样36例,呈弥漫分布105例;并颅内出血32例,小斑点出血或蛛网膜下腔出血27例,脑室内出血3例,硬膜下出血2例。12例患者1～4周复查CT,脑实质内低密度区复查后消失,出血病灶吸收,脑肿胀消退。结论螺旋CT可帮助HIE诊断,判断病情轻、重,并对治疗效果观察比较,有助于基础医院的HIE的诊断及治疗。

Objective To study the application of spiral CT in Hypoxi-ischemic encephalopathy（HIE） in neonates in the basic hospitals. Methods 144 neonates with clinically proved HIE underwent spiral CT,75 patients with HIE ,69 patients with HIE and other diseases. The spiral CT features were retrospectively analyzed. Results The CT features of HIE shows cerebral low density lesions in 144, local low density in 36, diffusive low density in 105 ; with cerebral hemorrhage in 32, mottling and Subarachnoid hemorrhage in 27, intraventricular hemorrhage in 3, Subdural hemorrhage in 2. 12 HIE were redetected within 1 -4 weeks. Cerebral low density le- sions,hemorrhage,cerebral swelling were disappear more or less. Conclusion Spiral CT has important signifi- cance for the CT diagnosis and prognosis of HIE and CT stage. It was helpful in HIE diagnosis and treatment in basic hospitals.
