title: A new surgical approach to the third ventricle with interruption of the striothalamic vein.
abstract: In the removal of tumours that develop within the third ventricle, most approaches are not entirely satisfactory. Therefore, a new approach has been devised: transfrontal exposure of the anterior portion of the frontal horn; coagulation and section of the striothalamic vein in order to open up the roof of the third ventricle; use of a blunt spatula introduced in the foramen of Monro and pushed backwards under the choroïd plexus. This approach has been used in ten cases. Postoperative mortality has been nil; the surgical approach has not apparently been responsible for any sequelae. It is simple and gives a good view of the third ventricle.
