摘　　要：目的探讨CT呈混杂密度的急性硬膜外血肿的临床特点和治疗策略。方法回顾性分析45例外伤后首次CT检查呈混杂密度的硬膜外血肿患者的临床资料，并与同期CT呈等密度的患者进行比较。结果在保守治疗的患者中，混杂密度的血肿增大概率（82．1％）远高于等密度血肿者（17．7％）（P〈0．01），手术患者病死率（16．2％）明显高于等密度血肿者（2．3％）（P〈0．01）。结论CT呈混杂密度可作为急性硬膜外血肿判断病情进展及预后不良指标，应引起临床医师的高度重视，早期诊断，预见性动态CT复查，适当放宽手术指征，早期手术干预，才能降低病死率。Objective To discuss the clinical characteristics and therapeutic strategy of acute epidural hema- toma（EDH） with mixed density on CT. Methods The clinical data of 45 patients with acute EDH with mixed density on the first CT after trauma were analyzed retrospectively. Acute EDH form trauma with mixed density on CT images were compared with those which had homogenesis density on CT images at the same time. Results The opportunity of increasing size of hematoma and the mortality was significantly higher in mixed density hematoma（ 82.1% , 16.2% ） than that of homogenesis density（ 17.7% ,2.3% ） （ all P 〈 0. 01 ）. Conclusion EDH with mixed density was a hy- peracute EDH. The operation for acute EDH from trauma with mixed density on CT image should be prompt.
