Case ReportsVentriculostomy-related cerebral hemorrhages after endovascular aneurysm treatment.
Recent evidence suggests that endovascular treatment of acutely ruptured aneurysms is equivalent, if not superior, to surgical treatment. Not all patients who undergo endovascular treatment do well, however. We have identified ventriculostomy-related hemorrhage to be a potential source of morbidity and mortality. ⋯ The risk of hemorrhage must be considered when using anticoagulation and antiplatelet therapy in patients requiring ventriculostomy. Interventionalists must not only work closely with neurosurgeons when it is anticipated that a ventriculostomy may be needed but also ensure that there is good communication with the neurosurgical team during the postprocedural period.

MR imaging of dural arteriovenous fistulas draining into cerebellar cortical veins.
Retrograde leptomeningeal venous drainage (RLVD) in a dural arteriovenous fistula (DAVF) is associated with intracerebral hemorrhage, nonhemorrhagic neurologic deficit, or death, and recognizing the presence of this drainage is important. We investigated the MR findings of DAVFs draining into cerebellar cortical veins and compared these findings with those of conventional angiography. ⋯ The characteristic MR findings of DAVF draining into cerebellar cortical veins represent venous congestive encephalopathy in the territory of the involved cortical vein.
