Objective To study the role of lateral ventricular drainage of cerebrospinal fluid (CSF) and CSF substitution in the treatment of serious tuberculous meningitis.

Objective To investigate the clinical efficacy of micro-invasive ventricle drainage with cerebrospinal fluid displacement therapy on severe ventricular hemorrhage.

There is no evidence that early tapping of cerebrospinal fluid by lumbar puncture or ventricular tap reduces the risk of shunt dependence, disability, multiple disability or death.
