Objective To investigate the method for the treatment of haemorrhage of all ventricles.Methods 46 cases were treated by continuous extrinsic drainage through puncture of the lateral ventricle which accumulated more blood combming with substitution of CSF by meams of lumbus puncture per day.Urokinase was injected into ventricle at regular intervals.Results The symptoms were improved.Head CT were reexamined in 41 cases,which showed disappearance of hematocele in ventricle within 4～15 days.Except for 5 cases of death,other cases recovered from the disease.Conclusion The hematocele above and below the duct in ventricle can be eliminated by this method,and the mortality rate can reduced greatly and the quality of survival can improved.
