小儿外伤性迟发性硬脑膜外血肿

目的 研究小儿外伤性迟发性硬脑膜外血肿的临床特点。并探讨其发生机制。方法 总结分析我科1991年1月-2001年10月收治的小儿外伤性迟发性硬脑膜外血肿23例。结果 本组手术清除血肿21例。血肿自行吸收2例。无死亡。结论 小儿迟发性外伤性硬脑膜外血肿多发生在伤后2-5d，占该类血肿78.3%，跌倒伤是主要的致伤原因，此类血肿可发生于颅内任何部位，但多伴有颅骨线形骨折。小儿外伤性迟发性硬脑膜外血肿及时发现和治疗，预后良好，CT扫描是可靠而简便的诊断方法，而延误诊断往往造成严重后果。

Delayed traumatic epidural hematomas in children

Objective To study the clinical characteristics and pathogenesis of the delayed traumatic epidural hematomas in children. Methods The study was carried out in 23 cases with delayed traumatic epidural hematomas who were treated at our department from January 1991 to October 2001. Results The epidural hematoma was removed in 21 patients without death. Conclusions The delayed traumatic epidural hematomas in children occurred most frequently at the 2nd-5th days after head injury accounting to 78.3%. Fall was the main injury cause. The hematomas might occur in every intracerebral part but were easily complicated by linear skull fractures. Delayed traumatic epidural hematomasshould be diagnosed and treated earlier, as can bring about a good prognosis. Repeated CT scanning was important for an early diagnosis. Otherwise, a serious outcome may occur.
