外伤性脑梗死的CT诊断

CT findings of traumatic cerebral infarction （ an analysis of 28 cases）

目的 探讨外伤性脑梗死的CT表现特征及诊断价值。方法 回顾性分析了自2005年9月至2007年3月经临床、CT证实的外伤性脑梗死28例，CT扫描采用SOMATOMSensation16螺旋CT扫描机，扫描条件：120KV，310MAs，其中1例行增强CT检查。结果 28例外伤性脑梗死病例中，23例可见原发颅脑损伤；1例首次CT检查即发现脑梗死，4例首次CT检查阴性，外伤后24—72hCT复查发现脑梗死。儿童脑梗死6例（约占21．4％），发生于手术后脑梗死8例（约占28．6％）。结论 CT扫描不仅能对外伤性脑梗死作出准确诊断，还能估计病变程度。

Objective To evaluate the findings and diagnostic value of CT scan for traumatic cerebral infarction. Methods A total of 28 cases of traumatic cerebral infarction diagnosed by clinical and CT findings from Sep 1998 to Mar 2003 were retrospectively analyzed. The patients were examined by Somatom Sensation 16 spiral CT scanner （scanning condition： 120KV, 310Mas）. One case was performed with enhanced CT. Results In 28 cases of traumatic cerebral infarction,23 cases had primary cerebral trauma; 1 case was shown infarction CT after trauma, 4 cases were not shown infarction by first CT, but confirmed by CT after 24 - 72h. Of the patients, 6 （21,4% ） were children,8 showed infarction after surgery （28, 6% ）. Conclusion CT scan has important diagnostic value for traumatic cerebral infarction.
