RESUMEN

Objetivo:

analizar retrospectivamente las características demográficas, topografía lesional, resultados anatomopatológicos y complicaciones de una serie de 65 biopsias estereotácticas cerebrales guiadas por tomografía. Materiales y

métodos:

estudio retrospectivo de 65 pacientes sometidos a 65 biopsias cerebrales estereotácticas guiadas con tomografía, desde enero 2012 hasta diciembre 2016, en el Hospital Carlos Andrade Marín (Quito-Ecuador).

Resultados:

se analizaron 65 pacientes con edad promedio de 48 años (rango 15 a 78 años); 42 pacientes fueron hombres (64,61%) y 23 mujeres (35,38%). 54 pacientes (83%) presentaron lesiones únicas y 11 (17%) múltiples. El porcentaje de resultados positivos fue de 80%; de los cuales, 76,92% correspondieron a patología tumoral, de ellos 69,23% fueron primarios del SNC y 7,69% fueron metástasis. Se registró 10,76% de complicaciones hemorrágicas asintomáticas y 9,23% de morbilidad registrada como transitoria. No se reportó infecciones del sitio quirúrgico ni infección post-operatoria relacionados con los cuidados de la salud. No registramos mortalidad.

Conclusiones:

la biopsia estereotáctica cerebral guiada por tomografía es una herramienta mínimamente invasiva, segura y eficaz para el diagnóstico anatomopatológico definitivo. La complicación más prevalente en esta serie fue la hemorragia post-biopsia; sin embargo, fue asintomática y no alteró la evolución de los pacientes; el resto de complicaciones correspondió a morbilidad transitoria. No registramos infección post-operatoria ni mortalidad.
ABSTRACT

Objective:

The aim of the present study was to analyze retrospectively demographic characteristics, lesion topography, anatomopathological results and complications of a series of 65 stereotactic brain biopsies. Materials and

methods:

65 patients who underwent 65 CT-guided stereotactic brain biopsies were retrospectively analyzed from January 2012 to December 2016 at Carlos Andrade Marín Hospital (Quito, Ecuador).

Results:

65 cases were reviewed. Patient age averaged 48 years (range 15-78 years); 42 patients were men (64,61%) and 23 women (35,38%). 54 patients (83%) had single lesions and 11 (17%) had multiple lesions. The percentage of positive results was 80%; Malignancy accounted for 76,92% of biopsied lesions, of which 69,23% were primary tumor of CNS and 7,69% were metastases. There were 10,76% of asymptomatic hemorrhagic complication and 9,23% of transient morbidity. We do not document any surgical site-related infection or post-operative infection related to health care. No mortality was recorded.

Conclusions:

Stereotactic brain biopsy guided by tomography is a safe and effective minimally invasive tool for obtaining a definitive anatomopathological diagnosis. The most prevalent complication in this series was post-biopsy hemorrhage, however, it was asymptomatic and did not alter the clinical evolution of the patients; the rest of complications corresponded to transient morbidity. We do not register post-operative infection or mortality.
