Intraventricular hemorrhage from ruptured aneurysm: clinical characteristics, complications, and outcomes in a large, prospective, multicenter study population.

ABSTRACT

OBJECT In this study the authors analyzed the relationship of intraventricular hemorrhage (IVH) to in-hospital complications and clinical outcome in a large population of patients with aneurysmal subarachnoid hemorrhage (SAH). METHODS: Data from 3539 patients with aneurysmal SAH were evaluated, and these data were obtained from four prospective, randomized, double-blind, placebo-controlled trials of tirilazad that had been conducted between 1991 and 1997. Clinical characteristics, in-hospital complications, and outcome at 3 months post-SAH (Glasgow Outcome Scale score) were analyzed with regard to the presence or absence of IVH. RESULTS: Patients with SAH and IVH differ in demographic and admission characteristics from those with SAH but without IVH and are more likely to suffer in-hospital complications and a worse outcome at 3 months post-SAH. CONCLUSIONS: The presence of IVH in patients with SAH has an important predictive value with regard to these aspects.
