Stereotaxic biopsy and implantation of Ir-192 in intracranial tumors. A review of seven years experience

Abstract:

Introduction. The combination of stereotaxic techniques, advances in neuroimaging and the creation of continually improving software has permitted stereotaxic biopsy of cerebral lesions at the most varied sites. Improvement in the method of permanent interstitial radiation (brachytherapy) improves the precision with which the radioactive sources may be inserted, releasing a maximum dose of radiation to the rumour with minimum radiation to the surrounding tissue. Patients and methods, We treated 237 patients (aged I to 78 years) with intracranial lesions, all included in the protocol of our centre. Stereotaxic systems of Leksell, Riechert-Mundinger, Micromar and Estereoflex were used. The procedure was in three stages: acquisition of the image, surgical planning and surgical operation. The imaging guide was the computerized axial tomography (CAT). Results. Stereotaxic biopsy guided by CAT images was done …
