目的 探讨超急性期血肿扩大速 度对脑出血血肿扩大的预测价值。方法 回顾性分析2016年6月到2017年7月出现症 状后6h内到我院就诊的78例超急性期脑出 血患者影像及临床资料，计算超急性期血 肿扩大速度(uHG)，即首次CT平扫上血肿 体积与发病至首次CT扫描时间的比值， 24h内复查CT用于评价血肿扩大，通过ROC 曲线分析uHG在预测血肿扩大的准确性， 确定uHG预测血肿扩大发生界值。结果 分 析纳入研究78例超急性脑出血患者的结果 显示，在出现血肿扩大患者中超早期血肿 扩大的速度加快(P<0.05)，ROC曲线分析 结果AUC下面积为0.880(95%CI，0.797- 0.963，P<0.001)，uHG=7.14ml/h时敏感 性(81.5%)和特异度性(88.2%)最高。结论 平扫CT上超急性期血肿扩大速度对血肿扩 大有预测价值，当血肿扩大速度=7.14ml/ h时可作为预测超急性期血肿扩大危险的 分层方案。

Objective To evaluate the value of hematoma enlargement rate in the diagnosis of hyperplasia of intracerebral hemorrhage. Methods The images and clinical data of 78 patients with hyperacute cerebral hemorrhage were analyzed retrospectively from June 2016 to July 2017. The ultre-early henmatoma growth (uHG) was calculated, that is, the first CT The ratio of hematoma volume to the time of first CT scan was reviewed. CT was used to evaluate hematoma enlargement. The ROC curve was used to analyze the accuracy of uHG in predicting hematoma enlargement and to determine the threshold of hematoma enlargement. Results Analysis of 78 patients with hyperacute cerebral hemorrhage showed that the rate of superficial hematoma enlargement was faster in patients with hematoma enlargement (P<0.05), and the area under the AUC was 0.880 (95% CI, 0.797-0.963, P<0.001). The sensitivity (81.5%) and specificity (88.2%) were the highest when uHG=7.14ml/h. Conclusion The rapid expansion of hematoma in CT scan is predictive of hematoma enlargement. When hematoma enlargement rate is 7.14ml/h, it can be used as a stratification scheme for predicting the risk of hyperosmolar hematoma enlargement.
