115例急性颅脑损伤动态CT分析

Dynamic Analysis of Computerized Tomography of 115 Patients with Acute Craniocerebral Injury

目的分析急性颅脑损伤后动态CT改变及迟发性颅脑损伤的发生机理,探讨CT复查的适当时间。方法回顾性分析我院及外院115例急性颅脑损伤动态CT改变及临床资料。结果伤后6h之内首次CT结果与再次复查结果比较44.2%有变化,伤后6～24h首次CT结果与再次复查结果比较20.4%有变化,两者比较,差异具有统计学意义。术后CT复查,35.2%的病人出现颅内迟发性损伤。结论外伤6h之后的CT较6h以内CT结果更能反映损伤程度和范围。根据病人的临床表现即时进行动态CT观察是至关重要的。

Objective To investigate the change of CT after acute craniocerebral injury and the mechanism of delayed brain injury, so as to find the proper time of re - examination of CT. Methods The changes of CT and clinical data of 115 cases were analyzed retrospectively. Results 44.2% of the re - examination results of were not correspondence with initial CT diagnosis within 6 hours. 20.4% of the re - examination results of were not correspondence with initial CT after 6 hours. The difference was significant. Delayed brain injury appeared in 35.2% of patients. Conclusions The results of CT after 6 hours were more important than that within 6 hours. Dynamic CT examination is necessary to patients with craniocerebral injury.
