Long Term Outcome After Hemorrhagic Stroke Surgery

January 10, 2013 updated by: George KC Wong, Chinese University of Hong Kong

Long Term Neurological and Cognitive Outcome After Neurosurgical Operation for Hemorrhagic Stroke (Intracerebral Hemorrhage)

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.

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.
