AbstractMassive intraventricular haemorrhage (IVH) complicating aneurysmal subarachnoid haemorrhage (SAH) is associated with a poor prognosis. Small observational studies suggest favourable results from fibrinolysis of the intraventricular blood. We performed an observational study on IVH in a large series of patients with SAH to assess the proportion of patients that may benefit from fibrinolytic treatment. From our prospective database we retrieved patients with aneurysmal SAH admitted between January 2000 and January 2005. We calculated the proportion of patients with massive IVH and the proportion of patients that are eligible for fibrinolysis on basis of clinical and CT-scan characteristics and assessed neurological outcome in a treatment strategy without fibrinolysis. Poor neurological condition was defined as World Federation of Neurological Surgeons scale 4 and 5, poor outcome as death or dependence 3 months after SAH. Of the 573 patients admitted with aneurysmal SAH, 59 (10%; 95% confidence interval CI 8-13%) had massive IVH, of which 55 were in poor clinical condition. For these 55 patients, the case-fatality rate was 78% (95% CI 66-88%) and the proportion with poor outcome 91% (95% CI 81-97%). Of the 55 patients, 31 (56%, and 5% of all patients SAH within the study period) fulfilled our eligibility criteria and were considered suitable for intraventricular fibrinolysis. At 3 months, 30 of these 31 eligible patients (97%; 95% CI 85-100%) had a poor outcome. Massive IVH occurs in 10% of patients with aneurysmal SAH. Half of these patients may benefit from intraventricular fibrinolysis. Without fibrinolysis outcome is almost invariably poor in these patients.
