[Retrograde positive ventriculography by sub-occipital catheterization of the ventricular system (author's transl)]

The authors describe a new method of retrograde selective ventriculography by means of which the necessity for making an opening in the skull and for a trans-cerebral ventricular puncture is avoided. Trough a sub-occipital puncture and cannula a radio-opaque catheter is guided under radiological control into the ventricular system.
