The investigators retrospectively reviewed all patients with neurosurgical operations for hemorrhagic stroke (intracerebral hemorrhage) between 1999 and 2008. Research assistant then telephoned the survivors for neurological and cognitive status.

Hemorrhagic stroke patients

Detailed Description:
Death at one year for intracerebral hemorrhage varies by location, with 42% for cerebellar in one series. Of patients who had intracerebral hemorrhage in the United States during 2002, only 20% are expected to be functionally independently at 6 months. Although case series established the value of selected timely hematoma evacuation, long term clinical outcome, especially on cognition, is not well described in the literature. With these in mind, we carried out this study.
