First Year of Leksell Gamma Knife Treatment at the Hospital NaHomolce - Results after 5 Years

Overview

The first Leksell gamma knife procedure was performed in Prague on 26th October 1992 and during the first year156 patients were treated at the department of stereotactic and radiation neurosurgery. 42% patients suffered froma vascular lesion, 39% of patients from a benign tumour and 19% patients from a malignant tumour. Radiosurgeryusing the gamma knife is a non-invasive stereotactic neurosurgical procedure. Radiosurgery, as microsurgery, mustbe evaluated not only early, but also the late effect after the treatment some years. Evaluation of the results is thereforean ongoing process and results of the first year with the 5-year follow up are presented. At this time radiosurgeryhas a zero treatment mortality and the present morbidity with regard to the diagnosis 0-10%.
