Hemorrhage rates of external ventricular drain (EVD), intracranial pressure gauge (ICP) or combined EVD and ICP gauge placement within 48Â h of endovascular coil embolization of cerebral aneurysms

EVD, ICP gauge or combined EVD and ICP gauge placements within 48 h after cerebral aneurysm coiling and under different anticoagulation or antiplatelet regimens seem to have no increased risk of hemorrhages compared to literature.
