312例CT混杂密度的创伤性急性硬膜外血肿分析

目的:探讨CT表现为混杂密度的创伤性急性硬膜外血肿的影像学特征及其对临床治疗方案选择的指导价值。方法:总结312例CT为混杂密度的创伤性急性硬膜外血肿患者CT图像和临床病情的变化情况,并与同期CT等密度的患者进行比较。结果:在保守治疗的患者中,CT混杂密度的血肿增大几率远高于CT等密度的血肿(P<0.01)。结论:对CT混杂密度的创伤性急性硬膜外血肿应放宽手术指征,并尽早手术清除血肿,暂无手术指征的应严密观察病情,并于伤后24小时内复查CT。

Traumatic acute epidural hematoma with mixed density on CT:a report of 312 cases

Objective: To investigate the imaging features of acute epidural hematoma from trauma with mixed density on CT imaging and its direct value for the selection of clinical treatment. Methods: To analyse the changes of the patient's condition and CT images in 312 cases retrospectively. Acute epidural hematoma from trauma with mixed density on CT image were compared with those which had homogenesis density on CT images at the same time. Results: The opportunity of increasing size of hematoma was higher in mixed density hematoma than that of homogenesis density. Conclusion: The operation for acute epidural hematoma from trauma with mixed density on CT image should be prompt. To get rid of acute epidural hematoma should be performed as early as possible in these cases. Those with no immediate operative indication should be observed tightly, and examined by CT in 24 hours after trauma.
