CT在新生儿缺氧缺血性脑病中的应用

Computer tomography scan in neonatal

目的 :了解新生儿缺氧缺血性脑病 (Hypoxic—IschemicEncephalopathy ;HIE)CT脑损伤类型。方法 :1995年 1月至 2 0 0 0年 6月 12 9例新生儿HIE作了头颅CT扫描 ,年龄生后 4h～ 7d。急性脑损伤分为轻、中、重三度 ,采用韩玉昆等报道的标准。 2 5例获得随访并复查CT ,随访的年龄 6个月～ 3岁。结果 :急性期头颅CT扫描正常 10例 ,轻度脑损伤 2 5例 ,中度脑损伤 58例 ,重度脑损伤 35例 ,2 5例复查头颅CT ,其中 6例已正常 ,19例有异常CT改变。结论 :CT对HIE新生儿脑损伤具有高度敏感性 ,有助于HIE脑损伤的研究并指导治疗及评估预后。

Objective: To study the pattern of injury in neonates with hypoxsic-Ischemic Encephalopathy(HIE).Methods:The scan was performed in 129 neonates with HIE with in 4 hours to 7 days of life.Between January 1990 and April 2000.Follow-up to scan was performed in 25 children with HIE age at 6 months to 3 years. Results:In acute period, The pattern of brain injury with HIE was normal of 10 cases,modarate of 26 cases、middle of 58 cases and severe of 38 cases.In long-term follow-up, The pattern of brain can was normal of 6 cases,persistent abnormalitys of l9 cases. Conclusion:CT is highly sensitivefor brain injury on HIE,it is also useful for search on HIE,decision-making for therapeutic options and evaluation of prognosis of patients.
