A Ventricular Infusion Technique for the Evaluation of Treated and Untreated Hydrocephalus
In 1970 Katzmann and Hussey reported a CSF infusion study that allowed the evaluation of resistance to CSF flow in humans . As many disorders of the CSF circulation involve abnormalities of resistance to CSF flow, this technique is of importance and has been found reliable . However, in its original application by the lumbar route there is a limitation in utility because the abnormality in resistance may be within the ventricular system. The technique described in this study allows the repeated assessment of resistance to the flow of CSF from the ventricular system by performing the test through a permanently implanted subcutaneous Rickham reservoir in which the connected catheter has been placed in the lateral ventricle.
