Theoretical study for use of Leksell's stereotactic frame in radiosurgery.

The authors examine all the problems connected with the use of Leksell's frame. These problems were studied specifically for the treatment of artero-venous malformation of the brain using small fields and movement therapy of a 10 MV linear accelerator. The technique allows the administration of high radiation doses (25-30) Gy into a very small target within a fraction. In this way the surrounding tissue receives a low dose. The treatment was initially simulated with a dummy. The dosimetry gives an accuracy of +/- 1.5%. This study has been able to resolve all the theoretical and practical problems demonstrating the feasibility of the project which has already been put into effect.

Iopamidol and metrizamide in cervical myelography: side effects, EEG, and CSF changes.

Two nonionic contrast media, iopamidol and metrizamide (Amipaque), were used for cervical myelography (C1-C2 puncture) in 95 consecutive patients. Both contrast media gave excellent radiographic results. Headache and vagal symptoms were similar in both groups, whereas metrizamide produced more electroencephalographic changes and epileptic seizures. Meningeal irritation occurred in both groups and was severe in three cases. Cerebrospinal fluid showed protein and cellular changes of inflammatory type in both groups. Iopamidol is considered to be the more suitable contrast medium for cervical myelography despite its slight neurotoxicity.

Microsurgical technique in the treatment of vascular compression of cranial nerves in the posterior fossa.

The authors report on 2 cases: cerebello-pontine syndrome and a trigeminal neuralgia with homolateral facial spasm. In both patients the clinical syndrome was thought to be of vascular origin and the vessels accompanying the nerves showed to be tightly anchored to them by means of arachnoid bridges. Microsurgery allowed for performing section of the arachnoid bridges in order to prevent the nerves from the continuous microtrauma due to the vascular pulsation, this being the pathogenic mechanism responsible for the suffering of the nerves themselves.
