目的研究高血压性脑出血血肿扩大发生率、时间及影响血肿扩大的相关因素。方法对502例高血压性脑出血患者发病后6h以内、6~24h、24~48h、48~72h及72h以上进行分组CT动态观察。结果血肿扩大发生率26.30%,其中发病6h内为48.80%,6~24h为30.69%,24~48h为17.35%,48~77h为15.00%,72h以上为6.45%。结论高血压性脑出血发病72h内血肿均处于不稳定状态,病程愈短,发生血肿扩大机会愈大;血肿形态不规则、合并有鼾症及睡眠呼吸暂停综合征、长期服用阿斯匹林者可能是引起血肿继续扩大的相关危险因素。
Objective To study the incidence of hypertensive intracerebral hemorrhage (ICH) and the related factors of hematoma enlargement. Methods 502 patients with hypertensive intracerebral hemorrhage within 6h after onset, 6 ~ 24h, 24 ~ 48h, 48 ~ 72h and 72h or more group CT dynamic observation. Results The incidence of hematoma enlargement was 26.30%. The incidence of hematoma was 48.80% in 6h, 30.69% in 6-24 h, 17.35% in 24-48 h, 15.00% in 48-77 h and 6.45% in 72 h. Conclusions The hematoma of unstable hypertensive intracerebral hemorrhage (ICH) is unstable within 72 hours. The shorter the course of the disease, the greater the chance of hematoma enlargement. The irregular shape of hematoma, combined with snoring and sleep apnea syndrome, long-term use of aspirin May be caused by the hematoma continue to expand the relevant risk factors.
