CT Findings and Its Diagnostic Value for Traumatic Intracranial Hematoma Complicated by Cerebral Infarction

目的探讨外伤性颅内血肿后脑梗死CT表现及诊断价值。方法回顾性分析2005年8月至2011年5月在深圳市宝安区西乡人民医院就治的50例外伤性颅内血肿后脑梗死患者的CT表现等临床资料,总结外伤性颅内血肿后脑梗死的CT表现。结果 50例患者入院后首次CT检查除4例阴性外,均出现不同性质及程度的颅内血肿;24 h内复查CT,颅内血肿范围不同程度增大,13例出现脑梗死,36例行开颅去骨瓣减压术或血肿清除术;72 h复查,37例出现脑梗死。结论外伤性颅内血肿后脑梗死CT表现有一定特点,螺旋CT检查方便、快捷,分辨率高,对外伤性颅内血肿后脑梗死的诊断有很大价值。

Objective To study CT performance and diagnostic value of CT scan for cerebral infarction after traumatic intracranial hematoma. Methods CT performance and other clinical data of 50 cases of cere-bral infarction secondary to traumatic intracranial hematoma were retrospectively analyzed, CT performance of which was summarized.
