Abstract: Objective To investigate the predictive effect of initial cranial CT on early hematoma enlargement in spontaneous intracerebral hemorrhage. Methods Three hundred patients with spontaneous intracerebral hemorrhage within 6 hours after onset were studied. Chi-square test and logistic regression analysis were used to detect the related factors which may indicate hematoma enlargement. Results Sixty-one (20.33% ) patients presented hematoma enlargement on cranial CT. Single factor and multivariate regression analysis showed that the following factors were associated with early hematoma enlargement: early onset, uneven density hematoma, moderate and severe brain atrophy and hematoma located at the basal ganglia. Conclusion Early onset uneven density hematoma, moderate and severe brain atrophy, and hematoma at basal ganglia are the factors which may indicate early hematoma enlargement in patiens with spontaneous intracerebral hemorrhage.

摘要： 探讨首诊头部CT 影像对自发性脑出血早期血肿扩大的预测价值。300 例发病后6 h 内入院的自发性脑出血患者，经CT 检查显示其中61 例（20.33%）发生早期血肿扩大，经单因素和多因素Logistic 回归分析显示，早期血肿扩大与首诊CT 距发病时间短、血肿密度不均匀、中至重度脑萎缩及血肿位于基底节内侧等因素有关。
