ABSTRACT
From 1969 to 1975, 12 patients were operated upon at the Kantonsspital Zürich by the senior author (MGY) for intramedullary spinal hemangioblastoma with the help of microtechnique. The purpose of this paper is to describe in detail the surgical technique and the results, and to comment on the historical, clinical, pathological, and radiological aspects of spinal hemangioblastoma and the complex of von Hippel-Lindau's Disease (multiple angiomatosis of retina, central nervous system, and viscera) with which it is associated.

The surgical technic used at the neurosurgical clinic in Zürich in eradicating arteriovenous malformations of the vein of Galen is described. It is based on experience with nine cases. The surgical approach is made posteriorly. The right occipital lobe is retracted laterally from the falx cerebri. The multiple feeding vessels demonstrated in the angiogram are occluded; first, on the right side, then the left, and finally beneath the malformation. The draining vein of Galen is not occluded or removed. The use of the operating microscope is essential.

The arterio-venous malformations of the corpus callosum are distinct clinical and surgical entities. Review of literature reveals 45 documented cases of which 32 were treated surgically. The authors (M.G.Y.) had 18 such patients of which eight involved the anterior and the middle portions of the corpus callosum. (No. 8 involved the whole callosum). The patients were in the younger age group. Headache and stiffness of the neck were the common presenting features. Seizures were rare and there was a paucity of localizing neurological signs. These AVMs are supplied mainly by the pericallosal arteries and occasionally by branches of the posterior cerebral artery. The drainage is by septal veins, the inferior sagittal sinus and the superior sagittal sinus. Radical excision of these AVMs in the anterior and the middle portions of the corpus callosum was accomplished without operative mortality and with minimal morbidity. Radical removal of these anomalies with microsurgical techniques is the treatment of choice.

Ten patients with arteriovenous malformations (AVM) involving the splenium of the corpus callosum are presented. All were treated by microsurgical techniques with no mortality and minimal morbidity. The diagnosis and operative technique is described, and these AVMs are compared with those involving the anterior and the middle portions of the corpus callosum.
