【摘要】：目的探讨头颅CT漩涡征对创伤性硬膜外出血血肿扩大的预测价值。方法选择本院急诊创伤性硬膜外血肿患者75例,于伤后6h内完成头颅CT检查,根据有、无漩涡征分为漩涡征阳性组、阴性组,发病后24h或病情恶化时常规复查头颅CT,依据多田公式计算硬膜外血肿量,比较分析两组患者血肿扩大的发生率。结果 75例患者中,CT发现漩涡征阳性组、阴性组分别为40%(30/75)、60%(45/75),血肿扩大占37.3%(28/75),其中,漩涡征阳性组为89.3%(25/28),阴性组为10.7%(3/45),两组患者血肿扩大发生率比较差异有统计学意义(χ2=25.72,P0.01)。结论头颅CT漩涡征可作为预测急性创伤性硬膜外血肿扩大的影像指标。
[Abstract]:Objective to evaluate the predictive value of CT whirlpool sign in predicting the enlargement of traumatic extradural haematoma. Methods Seventy-five patients with traumatic epidural hematoma in our hospital were examined by CT within 6 hours after injury. They were divided into positive group and negative group according to their existence and no whirlpool sign. 24 hours after onset or when the condition worsened, the brain CT, was routinely reexamined. According to the multi-field formula, the epidural hematoma volume was calculated and the incidence of hematoma enlargement was compared between the two groups. Results of the 75 patients, 40% (30 / 75) and 60% (45 / 75) were found vortex sign in CT positive group, 37.3% (28 / 75) in hematoma enlargement group, 89.3% (25 / 28) in whirlpool positive group, 30% (30 / 75) in negative group, 60% (45 / 75) in negative group, and 87.3% (25 / 28) in whirlpool sign positive group, respectively. The incidence of hematoma enlargement in the negative group was 10.7% (3 / 45), and there was a significant difference between the two groups (蠂 2, 25.72, P0.01). Conclusion CT whirlpool sign can be used as an imaging index to predict the enlargement of acute traumatic epidural hematoma.
