Therapeutic indications vary in patients with a malignant glioma of the brain and must be envisaged differently according to whether the patients is operable or not. These are the following possibilities according to previously defined criteria:
About 4 cases of arterio-veinous malformations located within the occipito-cerebello-mesencephalic dihedral (which is this region of the brain including the cistern of Galen and the surrounding formations : the quadrigeminal bodies forwards, the splenium of the corpus callosum upwards, the upper face of the cerebellum and the pedonculus cerebellaris superior below) the authors related their own experience. These 4 cases are detailed from a clinical point of view. Them, a synthetic study is undertaken in which a comparison is done between the literature and the clinical features encountered : headache, sub-archnoid hemorrhage, impairment of consciousness, clinical features such as cranial nerve impairment, nystagmus motor impairment, cerebellar deficit, hydrocephaly. The value of angiography, ventriculography and CAT is discussed. All these patients have been operated upon as far as the authors think that a better chance can thus be offered to them. The choice of the technique is discussed. For one patient, the sub-temporal route was performed ; but it seems worth using the posterior inter-occipital route : this allows a better view on the lesion and an easier treatment of the malformation. These 4 patients suffered post operatively of a visual defect. The control angiography revealed no more arterio-venious malformation in two patients, a mild one in two others.
The authors report their experience about 60 patients who suffered of a spondylolisthesis and who were treated by a surgical procedure. A posterior approach has been used for all the patients. After a brief review of the clinical and radiological features of the disease, the authors emphazise the advantages of the posterior approach; only this technique allows a correct access both to the bone and the nerve roots lesions. Two types of operations are proposed:--the ablation of the posterior arch of the concerned vertebra (Gill's operation).--a posterior arthrodesis by mean of an homograft, using one of the following technique: an Albee grafting a Bosworth grafting an ilio-transversary grafting. The results are considered from a clinical, and an anatomo-radiological point of view.
