【摘要】：目的探讨颅脑CT漩涡征对创伤性硬膜外血肿患者血肿扩大的评估价值。方法选取2013年1月—2014年5月南华大学附属第一医院收治的急性创伤性硬膜外血肿患者64例,根据颅脑CT有无漩涡征分为:阳性组31例,阴性组33例。分析颅脑CT漩涡征对预测血肿扩大的正确率、灵敏度、特异度、阳性似然比、阴性似然比。应用多元Logistic回归分析血肿扩大发生的影响因素。结果阳性组血肿扩大率为83.9%(26/31),阴性组血肿扩大率为51.5%(17/33),差异有统计学意义(χ2=7.590,P=0.006)。颅脑CT漩涡征预测血肿扩大正确率为67.2%(43/64)、灵敏度为60.5%(26/43)、特异度为76.2%(16/21)、阳性似然比为2.54、阴性似然比为0.52。多元Logistic回归分析结果显示,漩涡征与创伤性硬膜外血肿患者血肿扩大有回归关系(P=0.009)。结论颅脑CT漩涡征对创伤性硬膜外血肿患者血肿扩大具有较好的预测价值,临床意义较高。
[Abstract]:Objective to evaluate the value of CT whirlpool sign in evaluating hematoma enlargement in patients with traumatic epidural hematoma. Methods the acute traumatic epidural hematomas treated in the first affiliated Hospital of South China University from January 2013 to May 2014 were selected. 64 patients with extramembranous hematoma. According to the whirlpool sign of CT, there were 31 cases in positive group and 33 cases in negative group. The accuracy, sensitivity, specificity and positive likelihood ratio of spiral sign of craniocerebral CT in predicting hematoma enlargement were analyzed. Negative likelihood ratio. Multiple Logistic regression analysis was used to analyze the influencing factors of hematoma enlargement. Results the hematoma enlargement rate in positive group was 83.9 / 26 / 31). The hematoma enlargement rate in negative group was 51.5 / 17 / 33 (蠂 ~ 2 / 7.590). The correct rate of predicting hematoma enlargement by CT whirlpool sign was 67.243 / 64 and the sensitivity was 60.5 / 26 / 43). The specificity was 76. 2 / 21, the positive likelihood ratio was 2. 54, and the negative likelihood ratio was 0. 52. Multiple Logistic regression analysis showed that. There is a regression relationship between vortex sign and hematoma enlargement in patients with traumatic epidural hematoma. Conclusion the spiral sign of craniocerebral CT is a good predictor of hematoma enlargement in patients with traumatic epidural hematoma. The clinical significance is higher.
