Anatomical observations of the subarachnoid cisterns of the brain during surgery.

Subarachnoid cisterns and their contents are described briefly in the light of observations made during microsurgical explorations. The concept of intracranial surgery in terms of moving from one cistern to another is presented here with particular emphasis on the cisterns in surgical approaches to intracranial vessels and nerves for the treatment of aneurysms, arteriovenous malformations, and for surgery of basal tumors.

Arteriovenous malformations of the anterior and the middle portions of the corpus callosum: microsurgical treatment.

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.

Arteriovenous malformations of the splenium of the corpus callosum: microsurgical treatment.

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.

Arteriovenous malformations of vein of Galen: microsurgical treatment.

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.

Anterior approach to the cervical spine.

The anterior approach to surgical treatment of disorders of the cervical spine is described, and the technique and advantages are outlined. A series of 66 patients who underwent 75 procedures is reported. The follow-up period ranged from one to five years. Good to excellent results were obtained with 91% of the operations for disc disease, and good results in all cases of fracture-dislocation. Adequate relief of pain was obtained with anterolateral cordotomy in two patients with malignant disease. Only minor complications were encountered; these were easily corrected or cleared up spontaneously. This approach is recommended in preference to the posterior approach for disc disease and fracture-dislocations of the cervical spine.
