Why do you think the mortality rate is higher for hemorrhagic stroke versus embolic stroke? ?
Embolic strokes tend to be to a large degree an event. The consequences of the event cause a continued “ischemic cascade,” but the embolism is done and done. Leaks have an annoying tendency to continue to leak, and even if you discount all the other things going on, putting the extra fluid (blood) into the braincase, which has no elasticity, must increase intracranial pressure, and that increasing level of intracranial pressure is a major determinant in the mortality of those patients. Not only does it decrease cerebral perfusion pressure, having your uncus pushed down to your toenails just can’t be good for you.
