[Catheterization of the cerebral ventricles by the rostral method in cattle].

Abstract

A new means of access to the encephalic ventricles in the cow has been proposed, consisting of the catheterization of the olfactory recess, situated approximately 25 mm under the skin in the frontal region, vertically from a point situated 15 mm laterally from the median plane at the level of a line drawn between the lateral angles of the eyes. Radiographs show that a radioopaque medium can be diffused throughout the cavities on both sides.
