We retrospectively analyzed 40 pediatric cases of PFEDH. Their baseline characteristic, clinical presentation, imaging findings and outcomes were collected and analyzed. The ellipsoid volume equation X × Y × Z/2 was used to measure the hematoma volume. The Glasgow Outcome Scale (GOS) was used to assess the neurologic functional outcome.
A total of 40 pediatric PFEH patients were included with 8 patients having poor outcome and 32 patients having a relatively good prognosis. GCS score showed a significant difference between good and poor outcome groups (p < 0.001). Y value on CT image was significantly bigger in poor outcome group than good outcome group (p < 0.01). Similar results were got in X/Z value (p < 0.05) and Y/Z value (p < 0.01) which reflected the shape of hematoma. A predictive model with Y + X/Z showed the largest area under the ROC curve with a sensitivity of 75.0% and specificity of 93.7%.
GCS score at admission was closely related to the prognosis of the pediatric patients with PFEDH. The morphometry of PFEDH has a crucial role in judging the prognosis. Axial convex-shaped hematoma was associated with poor curative effect of surgical treatment.
方法:我们回顾性分析了40例小儿PFEDH。他们的基线特征,临床表现,收集并分析影像学表现和结局.采用椭球体积方程X×Y×Z/2测量血肿体积。格拉斯哥预后量表(GOS)用于评估神经功能结局。
结果:共纳入40例小儿PFEH患者,其中8例患者预后较差,32例患者预后较好。GCS评分在好和差结果组之间显示出显着差异(p<0.001)。结果不良组的CT图像Y值明显大于结果良好组(p<0.01)。X/Z值(p<0.05)和Y/Z值(p<0.01)反映了血肿的形态。Y+X/Z预测模型显示ROC曲线下面积最大,敏感性为75.0%,特异性为93.7%。
结论:入院时GCS评分与PFEDH患儿的预后密切相关。PFEDH的形态计量学在判断预后中起着至关重要的作用。轴向凸状血肿与手术治疗效果差有关。
