| ［摘要］ 目的 研究头颅彩色多普勒血流动力学和颅内结构改变在诊断新生儿缺血缺氧性脑病（HIE）中的应用价值。方法 应用彩色多普勒及二维超声检测58例HIE患儿及20例正常出生1～2 d内新生儿的大脑中动脉、大脑前动脉参数及脑组织结构变化情况。结果 出生1～2 d内窒息的早产儿及足月儿大脑中动脉和大脑前动脉收缩期峰值流速(Vs)及舒张末期流速(Vd)较对照组下降，阻力指数较对照组升高，与对照组比较差异有统计学意义（P<0.05）,双侧或单侧侧脑室冠状面前角变小，甚至不显示，侧脑室周边脑组织回声增强，呈放射状或脑实质内广泛均匀分布的轻度回声增强。结论 彩色多普勒及二维超声对诊断HIE及指导治疗有着重要意义。 |

| Abstract: |
| ［Abstract］ Objective To study the value of the color Doppler flow dynamics of skuall and intracranial structural change in the diagnosis of neonatal hypoxic-ischemic encephalopathy (HIE).Methods Color Doppler and two-dimensional ultrasound were used in 58 children patients of HIE and 20 normal newborns within 1～2 days for testing the parameters of the middle cerebral artery and anterior cerebral artery and structural changes in brain tissue.Results The systolic and diastolic blood flow relocithy of middle cerebral artery and anterior cerebral artery in preterm children and full-term children of asphyxin decreased compared with the control group and the resistance index was higher than the control group. These differences between two groups were obvious (P<0.01).The front angle of curonal plane in bilateral or unilateral lateral ventricle became smaller, or even disappear.The echo in the brain tissue around the lateral ventricle was enhanced radially or the echo was mildly enhanced, and evenly distributed widely within the brain parenchyma. Conclusion Color Doppler and two-dimensional ultrasound in the diagnosis of HIE and guiding therapy is of great significance. |
