[Operative treatment of tumors of ventricles I-III following experiences 1953-1983].

A report is given on the experience gained in 254 patients presenting processes of the ventricles I-III at the Leipzig Hospital within a period of thirty years. The rate of radical operations rose from 29% to 60%. At present, however, inoperability is restricted almost exclusively to general surgical aspects. Palliative operations are carried out in the form of the V-A shunts. Of decisive importance is the use of microtechniques in conjunction with an optimum anesthesia and intensive care. The accesses used are shown in pictures. Special surgical aspects are benignity of many intraventricular tumours, pronounced vascularisation, localisation below functionally important corticocerebral regions as well as exact considerations with respect to the planning of the operation pathway.
