The frame-based stereotactic biopsy is a minimally invasive technique that allows us to obtain a sample of brain tissue for subsequent diagnosis and treatment. The scope of this article is to review the published data related to the factors that could condition its diagnostic yield, and the appearance of post-biopsy hemorrhagic complications. PubMed search, last updated June 2020, was conducted using the terms “stereotactic biopsy”, “diagnostic yield” and “intracranial post-biopsy hemorrhage”. A total of 38 studies, that showed descriptive or analytical results, were included, and reviewed. Our literature review show that some characteristics of the lesion and surgical procedure peculiarities are significantly related with the effectiveness and safety of the technique. In this way, they must be taken into account in order to optimize its results.
La biopsia estereotáctica con marco es un procedimiento mínimamente invasivo que permite la obtención de una muestra de tejido cerebral para el posterior manejo diagnóstico terapéutico del paciente. Nuestro objetivo es realizar una revision de la literatura publicada en relación a los factores asociados a su rendimiento diagnóstico y a la aparición de complicaciones hemorrágicas postbiopsia. Para ello, fue realizada una búsqueda en PubMed, última actualización de Junio de 2020, empleando los términos “stereotactic biopsy”, “diagnostic yield” e “intracranial post-biopsy hemorrhage”. Un total de 38 estudios, que mostraban resultados descriptivos y/o analíticos, fueron incluidos y revisados. Nuestra revision de la literatura pone de manifiesto que algunas variables relacionadas con las peculiaridades de la lesion y el procedimiento quirúrgico se relacionan de forma significativa con la eficacia y seguridad de la técnica. De esta forma, deben ser tenidos en cuenta para optimizar los resultados de este procedimiento.
