Intracerebral haemorrhage (ICH) is a common and serious disease. About 1 to 2 out of 10 patients with stroke have an ICH. The mortality of ICH is higher than that of ischaemic stroke. Only 31% are functionally independent at 3 months. Only 38% of the patients survive the 1(st) year. The cost of ICH is high. Hypertension is the major risk factor, increasing the risk of ICH about 4x. Up to half of hypertensive patients who suffer a ICH are either unaware of their hypertension, non-compliant with the medication or fail to control periodically their blood pressure levels Microbleeds and white matter changes are MRI markers of the risk of ICH. ICH has 3 main pathophysiological phases: arterial rupture and haematoma formation, haematoma enlargement and peri-haematoma oedema. Up to 40% of the haematomas grow in the first hours post-rupture. ICH growth is associated with early clinical deterioration. Two randomised clinical trials (RCTs) demonstrated that treatment with rFVIIa limited haematoma growth and improved outcome, but was associated with a increase in thromboembolic complications. Ventricular drainage with thrombolytics might improve outcome for patients with intraventricular bleeding. A large RCT and meta-analysis failed to show a benefit of surgery over conservative treatment in acute ICH.
脑出血(ICH)是一种常见且严重的疾病。每10名中风患者中约有1至2人患有脑出血。脑出血的死亡率高于缺血性中风。仅31%的患者在3个月时功能独立。仅38%的患者能存活1年。脑出血的治疗成本很高。高血压是主要危险因素,使脑出血风险增加约4倍。高达一半的脑出血高血压患者要么不知道自己患有高血压,要么不遵医嘱服药,要么未能定期控制血压水平。微出血和白质改变是脑出血风险的MRI标志物。脑出血有3个主要病理生理阶段:动脉破裂和血肿形成、血肿扩大和血肿周围水肿。高达40%的血肿在破裂后的最初几小时内会增大。脑出血的扩大与早期临床恶化相关。两项随机临床试验(RCT)表明,重组活化凝血因子VII(rFVIIa)治疗可限制血肿扩大并改善预后,但与血栓栓塞并发症增加有关。使用溶栓剂进行脑室引流可能会改善脑室内出血患者的预后。一项大型RCT和荟萃分析未能显示在急性脑出血中手术比保守治疗更有益。
