VOLUMETRIC RECONSTRUCTION AND STEREOTAXIC COMPUTER-ASSISTED RESECTIONIN INTRACEREBRAL LESIONS

Since 1990 112 patients have undergone stereotactic resection of intra -axial tumoural lesions with volumetric reconstruction, using the Kell y-Goerss system. Stereotactic integration of CT, angiographic and part icularly MRI information, together with three-dimensional information of the lesion, provide an innovative evaluation of the most appropriat e surgical approach, even for each single patient. The main limitation of this surgical method is in cases where the infiltrating part of th e tumour is pre-eminent, while it can allow ''macroscopically complete resection'' of well circumscribed lesions, almost independently of th eir location and volume. Some technical aspects of stereotactic resect ion of brain tumours are discussed in the light of our experience.
