Specific treatment in the acute phase after cerebral haemorrhage is still not available. Corticosteroids and early surgical evacuation have been proven to be ineffective. In the initial 3 hours after a cerebral haemorrhage, the haematoma volume increases in one-third of all patients. Arresting this enlargement may be an effective strategy to improve outcome. Recombinant activated factor VII (rFVIIa) is used to treat bleeding in patients with haemophilia and has also been reported to reduce bleeding in patients without coagulopathy. In a recently published phase-II trial totalling 399 patients given placebo or one of three doses of rFVIIa, treatment with rFVIIa reduced haematoma volume 24 hours after administration. Treatment with rFVIIa was also superior to placebo for several secondary endpoints, including death, handicap and neurological deficits. However, more thromboembolic complications, including myocardial infarction and ischaemic stroke, occurred in the groups given rFVIIa. A new trial, with death or dependency as the primary outcome, has recently been started. The results are expected early in 2007.
脑出血急性期仍无特效治疗方法。皮质类固醇和早期手术清除血肿已被证明无效。在脑出血后的最初3小时内,三分之一的患者血肿体积会增大。阻止这种增大可能是改善预后的有效策略。重组活化因子VII(rFVIIa)用于治疗血友病患者的出血,也有报道称其可减少非凝血功能障碍患者的出血。在最近发表的一项II期试验中,共有399例患者接受了安慰剂或三种剂量rFVIIa中的一种治疗,rFVIIa治疗可在给药24小时后减少血肿体积。rFVIIa治疗在包括死亡、残疾和神经功能缺损等几个次要终点方面也优于安慰剂。然而,接受rFVIIa治疗的组中出现了更多的血栓栓塞并发症,包括心肌梗死和缺血性中风。一项以死亡或依赖为主要结局的新试验最近已经启动。预计2007年初会有结果。
