Proceedings of the 8th European Congress of Neurosurgery, Barcelona, September 6-11, 1987

th The 8 European Congress of Neurosurgery which took place in Barcelona from September 6 to 11, 1987, was an unforgettable experience. Many factors contributed to its success: the splendid ambience of Barcelona, the generous hospitality and warm friendship of the hosts, and the marvellous organization and high scientific standard of papers, workshops and discussions. For financial reasons it would not have been possible to publish all the papers presented during the congress. In order to preserve as much as possible of the scientific results, the Programme Committee of the European Association of Neurosurgical Societies had already selected before the congress a certain number of abstracts to be published as full papers. These are compiled in two supplement volumes of Acta Neurochirurgica and deal with the following main topics: Volume 1: 1. Intraoperative and posttraumatic monitoring and brain protection 2. Cerebro-vascular lesions 3. Intracranial tumours 4. Benign intracranial cystic lesions, hydrocephalus, CSF-volumes 5. Central pain syndromes Volume 2: 6. Spinal cord and spine pathologies 7. Basic research in neurosurgery. The Editors F. Isamat, A. Jefferson, F. Loew, L. Symon Contents Listed in Current Contents VI. Spinal Cord and Spine Pathologies Fornari, M., Pluchino, F., Solero, C.
