  1. 脑室内出血的超声检查

  2. 检查方法 • 冠状切面 • 矢状切面 • 经过未闭合的前囟、后囟及侧囟

  3. 脑室 体部正常值：mm • 新生儿：1.6 • 1个月：1.8 • 3个月： 2.9 • 6个月：2.7

  4. 脑室内出血 • ＜32周 • ＜1500g • 早产儿 • 72小时内发生

  5. 检查范围 • 脑室内出血 • 室管膜下出血 • 脑实质出血 • 巨大硬膜下出血 • 囊肿及脑室增大等病变

  6. 脑室内出血分型 I:室管膜下胚胎生发层基质出血 II:室管膜下出血穿破室管膜进入食管腔，引起脑室内出血 III:脑室内出血伴脑室扩张 IV:脑室内出血伴脑室周围出血性梗死

  7. 正常

  8. 正常

  9. 脑室前角

  10. I级室管膜下出血

  11. II级室管膜出血 • 出血穿破室管膜进入脑室腔 • 超声表现:原呈无回声的侧脑室内呈现强回声

  12. III级脑室内出血 • 脑室内出血伴脑室扩张。 • 超声表现：扩张的侧脑室内部分或完全性由高回声的积血充填。

  13. IV级脑室出血 • 除脑室内出血外，伴有脑室周围白质出血梗死

  14. 谢谢您的聆听
