Primary intraventricular hemorrhage

Primary intraventricular hemorrhage is very unusual, except in premature babies. In adults, a cause is not always found. Some may be secondary to a vascular malformation in the ventricular wall (Gates et al. 1986 Darby et al. 1988). The clinical features may be indistinguishable from subarachnoid hemorrhage and it may only be differentiated at autopsy. 

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...
