SURGERY FOR LATE RADIATION NECROSIS FOCI IN THE FUNCTIONALLY IMPORTANT CEREBRAL AREAS

Abstract

Background. Appearance and development of new radiotherapy methods for primary and secondary cerebral tumors resulted in more frequent diagnosis of post radiosurgical complications. A common sequel of treatment with linear accelerators is radiolesions of brain tissue.Objective. Study outcomes of surgical treatment for cerebral radiation necrosis foci.Materials and Methods. We included 3 patients with late radiolesion foci of brain tissue with progredient course, operated on in Scientific Research Institute – Ochapovsky Regional Clinical Hospital no. 1, for the period since January 1, 2015 to April 30, 2017. Age rate was 61–65 years and mean age was 63 years. Below we present a clinical case of surgical treatment for post radiation surgery necrosis.Results and discussion. Increased focal volume in the late radiotherapy period with simultaneously expressed rise of local hypostasis in brain tissue could indicate development of a late post-radiation perifocal necrosis. Conclusion. Our observations showed surgical efficiency for post-radiosurgery complications treatment.
