A new surgical approach to the third ventricle with interruption of the striothalamic vein.
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.
