Intracerebral hemorrhage (ICH) is a highly morbid form of stroke. Recent research has sought to identify pathologic processes that continue to evolve after patients present for medical care, with the hope that those delayed injuries may be effectively detected and intervened upon to improve outcomes. Our group recently reported an observation that delayed intraventricular hemorrhage (dIVH) developed in 21% of ICH subjects with no intraventricular hemorrhage (IVH) present on initial imaging.1 IVH has been characterized as an independent contributor to poor outcomes, and recognizing that delayed development of IVH was fairly common, along with the more widely recognized phenomenon of parenchymal hematoma growth, advanced it as another potential candidate for hemostatic treatments. Moreover, dIVH showed approximately the same effect size in contributing to death within 2 weeks and poor outcomes at 3 months as IVH on initial imaging, suggesting that IVH posed similar morbid consequences regardless of when it occurred.
