血肿密度与脑出血早期血肿扩大的相关性

目的分析脑出血早期血肿不均匀密度与血肿扩大的关系。方法收集深圳市数家医院发病6h内行第1次头部CT检查,48h内复查头部CT的非手术脑出血病例资料,共120例。将入院后首次头部CT所示血肿按不同的密度分级标准评级,分为血肿密度均匀组和血肿密度不均匀组,统计学分析对比两组年龄、性别、入院时收缩压、舒张压、出血量、纤维蛋白原浓度及血肿扩大发生率的差异。结果密度均匀组和密度不均匀组的年龄、性别、入院时收缩压、舒张压、纤维蛋白原浓度无显著性差异。密度不均匀组血肿比密度均匀组血肿明显大(t=-3.660,P=0.000);血肿扩大发生率显著增高(χ2=5.40,P=0.026),但两组首次头部CT出血量无显著差异t=-1.005,P=0.317)。血肿密度不均匀组发生血肿扩大和不发生血肿扩大的出血量无显著差异(t=0.843,P=0.405)。结论较大血肿的密度更不均匀,密度不均匀血肿比密度均匀血肿更易出现血肿扩大。出血量不是血肿扩大的危险因素。密度不均匀血肿可能是血肿扩大的重要危险因素之一。

Relationship between density heterogeneity and intracerebral hemorrhage growth

Objective We analyzed the relationship between density heterogeneity and ICH growth. Methods We reviewed the clinical records of 120 patients with spontaneous intracerebral hemorrhage treated nonsurgically who underwent initial computed tomography(CT)within 6 hours and repeated CT within 48 hours of onset. The baseline CT images were defined as homogeneous(Category 1 to 2)or heterogeneous(Category 3 to 5)by the novel 5-point categorical scales of density. Contrasted the clinical data of these 2 groups and a...
