[Postoperative neurosurgical complications in brain tumors operated in the elderly]

200 patients of geriatric age, operated on for cerebral neoplasm, have been studied in order to estimate the most important factors influencing the post-operative course. We have considered the "Volume of the tumour", the "Pre-operative and at-discharge Karnofsky Score", the possible "Pre-existent pathologies" and the checked "Post-operative complications". As a conclusion we have considered relevant over the final outcome the following factors: a) the presence of general pre-existent pathologies, first of all diabetes and hypertension; b) the volume, more than the site and nature, of the neoplasm subject of the operation; c) the nature and the importance of local post-operative complications.
