A Randomised Controlled Trial of Lumbar Drainage to Treat Communicating Hydrocephalus After Severe Intraventricular Hemorrhage

All patients requiring external ventricular drain (EVD) for treatment of acute obstructive hydrocephalus receive intraventricular fibrinolysis with rt-PA via the ventricular catheter. Lumbar drainage (LD) is inserted at a timepoint, when communication between the internal and the external CSF-spaces is recognizable on CT ("opening" of third and fourth ventricle and aqueduct).
