Aim To investigate the efficacy and prognosis of early intervention treatment in cerebral aneurysms ruptured. Methods 101 cerebral aneurysms ruptured patients were selected from April 2007 to February 2011 in our hospital,all patients were treated with interventional micro-coil embolization,including 51 patients with intervene treatment in the early rupture(3 day) as early treatment group,50 patients with non-early interventional treatment as control group.All patients were postoperatively followed-up,with improved mRS score to evaluate the healing effect. Results The healing effect of patients in early treatment group had the significant difference compared with control group(P<0.05),contrast between groups showed that early treatment group's mRS score were significantly lower than that of control group(P<0.05).And contrast within the group showed that mRS score of patients under Hunt-Hess grade Ⅳ was significantly lower than the Hunt-Hess grade Ⅳ,Ⅴ patients(P<0.05).Contrast between the age showed age ≥ 60 patient's mRS score were higher than age <60 patients(P<0.05).Contrast between the aneurysm size and the treatment effect showed small and medium patient's mRS score had significant difference compared with large and huge patients(P<0.05).Early treatment group's complication were significantly lower than that in control group(P<0.05). Conclusion Early intervention micro coil embolization in intracranial aneurysm rupture has the remarkable curative effect,and can significantly reduce the incidence of postoperative complications and the chance of aneurysm rupture again,and improve the patients' outcomes.
