LANDRIEL, Federico et al. Biopsia estereotáctica cerebral guiada tomográficamente: Análisis de una serie de 192 casos. Rev. argent. neurocir. [online]. 2008, vol.22, n.3. ISSN 1850-1532.
Objective. Stereotactic CT-guided biopsy is a safe procedure for the diagnosis of brain lesions unsuitable for surgical treatment because of their location, number, histology or poor medical status. The objective of this study is to analyze the indications, demography, topography, anatomopathologic diagnosis and complications in a series of stereotactic CT-guided brain biopsies. Method. 192 CT assisted stereotactic brain biopsies in 186 patients were retrospectively reviewed from june 1998 to june of 2008. Results. 186 patients, 101males (54.3%) and 85 females (45.7%), were analyzed. Mean age was 54.5 years. 144 (75%) of the biopsies were performed in hemispheric lesions, 43 (22.4%) in "deep seated" localization. The most frequent anatomopathologic diagnosis were glioblastoma (36,5%) and anaplasic astrocytoma (17%). 90,62% of the biopsies were positive, 7,3% were negative and 2,08% non diagnostic. Morbility rate was 3,64% and mortality 2,08%. Conclusion.Stereotactic brain biopsy is a safe and effective procedure providing tissue for definitive anatomopathological diagnosis; it offers low morbidity and mortality rate. Our findings are similar to the literature.
