My grandma's vein in her brain busted and has a clot now. she cannot have an operation due to swelling, what are the survival rates???

Some statistics: Intracranial bleeding can be very scary, as 50 % of aneurysmal ruptures do not survive to be hospitalized. Intracranial hemorrhages in older folks have a mortality of 60% within the first year. However, it seems your Grandma's situation may turn out positive over time. Communicate with her doctors frequently to gauge where this is going.
