What happens when a shunt drains too much?
Over-drainage: When the shunt allows cerebral fluid to drain from the brain’s ventricles more quickly than it is produced, the ventricles can collapse, tearing blood vessels and causing bleeding in the brain or blood clot, marked by severe headache, nausea, vomiting, seizure and other symptoms.
What happens if too much CSF is drained?
It is possible that the puncture of the ventricle or the opening of the dura will result in an intracranial hemorrhage.
