115例急性颅脑损伤动态CT分析

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。

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

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.
