Mortality primary intracerebral hemorrhage

In subarachnoid hemorrhage due to a ruptured intracranial aneurysm or arteriovenous malformation, surgical intervention to clip or ablate the vascular abnormality substantially reduces mortality from rebleeding. The benefits of surgery are less well documented in cases of primary intracerebral hemorrhage. In patients with intracerebral hematomas, insertion of an intraventricular drain with monitoring of intracranial pressure is... 

Recently, Szczudliket al. (4) studied 152 patients with supratentorial primary intracerebral hemorrhage (PICH) confirmed by CT on admission. In that study, outcome was measured by either mortality or Barthel...

In most studies, both stroke mortality and hospital admission rates are higher in winter than in summer (Douglas et al. 1991 Pan et al. 1995 Feigin and Weibers 1997). This seasonal variation might be explained by the complications of stroke being more likely to occur in the winter (e.g. pneumonia) and cannot simply be assumed to reflect stroke incidence. Where incidence has been measured in the community, there is little seasonal variation, at least in temperate climates, although primary intracerebral hemorrhage is somewhat more likely in the winter months and on cold days (Rothwell et al. 1996 Jakovljevic et al. 1996).
