众所周知,自发性脑内出血(ICH)多为短时出血,但仍有部分患者继续出血致使血肿扩大。作者分析了419例ICH患者,以评价血肿扩大的发生情况及危险因素。其中男性272例,年龄36～91岁(平均59.9岁)女性147例年龄37～94岁(平均56.9岁)。发病后24h内首次CT扫描,入院后24h内第2次CT扫描。揭示血肿扩大的标准为血肿体积增加超过首次扫描时血肿体积的50％以上,或两次CT血 As we all know, spontaneous intracerebral hemorrhage (ICH) mostly short-term bleeding, but there are still some patients continue to hemorrhage caused hematoma enlargement. The authors analyzed 419 ICH patients to assess the occurrence of hematoma enlargement and risk factors. There were 272 males and 147 females aged 36-91 years (average 59.9 years), aged 37-94 years (average 56.9 years). The first CT scan within 24 hours after onset, the second CT scan within 24h after admission. The standard for revealing hematoma enlargement is that the hematoma volume increases more than 50% of the hematoma volume at the time of the first scan, or two CT bloods
