Combined microsurgical fluorescence for optimizing resection in refractory empyema and cerebritis.

PURPOSE: Due to the generalization of new microsurgical equipment, intraoperative fluorescence techniques have extended in neurosurgical practice, mainly in neurovascular and neuro-oncology patients. The aim of identifying pathological tissue and also differentiating from the normal brain helps neurosurgeons to approach other kinds of intracranial entities such as infections. METHODS: It is described in the case of an 11-year-old patient who underwent a subdural empyema by performing a craniotomy and evacuation of the purulent collection. After a non-optimal evolution, a frontobasal meningoencephalitis was assessed with cerebral involvement and associated intracranial hypertension. Indocyanine green (ICG) was used in reintervention for demonstrating a great damage of cortical vascularization around the infected area as well as fluorescein (FL), which identified a large area of avascularized tissue. RESULTS: Both techniques allowed a selective excision of the affected brain parenchyma while preserving viable parenchymal areas. Radiological evolution and clinical outcome were good. CONCLUSIONS: The identification of vascular patterns in brain lesions and the recognition of viable or necrotized tissues are suitable for a selective resection of the parenchyma, minimizing morbidity. Clinical outcome is related to a safe and effective management of inflammatory and infectious processes.

Análisis de los factores que influyen en el resultado final del traumatismo craneal moderado / Analysis of the factors influencing the final outcome of moderate head injury

Introducción: El traumatismo craneoencefálico (TCE) es un fenómeno muy frecuente, asociado a elevadas tasas de morbilidad. Objetivo: Describir una serie amplia de pacientes adultos, mayores de 14 años, que sufren TCE moderado atendidos en el Hospital Universitario de Getafe, entre los años 2005 y 2015, estudiar el perfil epidemiológico y analizar el diagnóstico y el tratamiento efectuados, así como establecer los principales factores pronósticos que influyen en el resultado final. Método: Se ha realizado un estudio retrospectivo, de revisión de historias clínicas y entrevistas telefónicas. Resultados: Se ha estudiado un total de 66 pacientes que sufren TCE moderado. El TCE moderado es más frecuente en varones, y el mecanismo causante más común es el accidente de tráfico. Conclusiones: El presente estudio establece la necesidad de ingreso hospitalario, ya sea en planta de Neurocirugía o en la Unidad de Cuidados Intensivos (UCI), en función de la situación clínica del paciente y de los hallazgos radiológicos encontrados en la Tomografía Computarizada (TC). Las variables que han resultado determinantes de la evolución adversa en el paciente que sufre trauma craneal moderado son los hallazgos patológicos en la TC, la existencia de focalidad neurológica, la presencia de deterioro clínico, la edad avanzada, los hallazgos en la TC de control, y los atropellos, caídas e impactos directos como mecanismos causantes. Existe diferencia de pronóstico entre pacientes con puntuación de 11 y 12, con una evolución más parecida al del paciente que sufre trauma leve, y los que obtienen 9 y 10 puntos, con un pronóstico más similar al del trauma grave.

Introduction: Head injuries are very frequent and associated with high morbidity rates. This paper describes a large series of patients, all ≥14 years old, who suffered moderate head injuries and were treated at the University Hospital of Getafe, between 2005 and 2015 (n = 66). Our aims were (1) to examine patients' epidemiological profile; (2) to describe the best diagnostic and therapeutic measures performed; and (3) to identify the main determinants of final outcome. Methods: This was a combined retrospective and prospective study, consisting first of a review of medical records, followed by telephone interviews of eligible patients to determine final outcomes. Results: Sixty-six patients with moderate head injuries were studied. In this series, most patients were males, and the most common causative mechanism was a traffic accident. The needs for hospital admission, admission into the Neurosurgery service, and admission to Intensive Care Unit (ICU) were determined by patients' clinical presentation and radiological findings. Risk factors for a poor final neurological outcome were the presence of neurological defects during the initial clinical examination, findings on brain computerized tomography (CT), and patient age. The Glasgow Coma Scale was poor at predicting the final outcome in these patients with moderate head injuries, incapable of distinguishing between patients with a score of 11 or 12, more similar to mild trauma, and those with scores of 9 or 10 points, more similar to severe head trauma. Conclusions: In this series of adolescent and adult patients with moderate head injuries, the best predictors of final outcome were the initial presence/absence of neurological defects and CT findings, and patient age. The Glasgow Coma Scale was less useful.

Factores pronósticos del traumatismo craneoencefálico grave / Prognostic factors for severe head injury

Introducción: El traumatismo craneoencefálico (TCE) es un fenómeno frecuente, asociado a elevadas tasas de morbilidad. Clásicamente se ha prestado más atención al traumatismo craneal grave o severo, dada la trascendencia del problema sanitario. Objetivo: Describir una serie de pacientes mayores de 14 años, que sufrieron TCE grave atendidos en el Hospital Universitario de Getafe entre los años 1993 y 2015 (n = 86), estudiar el perfil epidemiológico de presentación, y analizar el diagnóstico y tratamiento efectuados, así como establecer los principales factores pronósticos que influyen en el resultado final. Método: Se ha realizado un estudio retrospectivo, de revisión de historias clínicas y entrevistas en Consultas Externas. Resultados: El TCE grave es más frecuente en varones, y el mecanismo causante más común en nuestro medio es el accidente de tráfico. En este estudio, las variables que han resultado más determinantes de la evolución adversa en el paciente que sufre trauma craneal grave son la edad, el tamaño y la reactividad pupilar, la peor puntuación obtenida por el paciente en la escala de Glasgow para el Coma y las lesiones encontradas en la Tomografía Computarizada (TC) de cráneo. Conclusiones: Las lesiones en el trauma craneal grave se pueden categorizar en nueve patrones patológicos de acuerdo con la información aportada por la TC. Estos patrones presentan un perfil anatómico, clínico y una significación pronóstica bien definidos, asociándose a su vez a un patrón de comportamiento de la PIC característico. Los hematomas extra-axiales puros son las lesiones que presentan mejor pronóstico, siendo la lesión axonal difusa asociada a hinchazón cerebral y las contusiones múltiples bilaterales las que conllevan peor evolución. La Escala de Rimel se ajusta correctamente a la severidad del traumatismo craneal. La Escala de Glasgow para el Coma se relaciona bien con el pronóstico final del paciente con trauma craneal grave.

Introduction: Head injury is a very frequent event, associated with high morbidity rates. Classically, more attention has been paid to severe trauma. This paper describes a large series of patients, all ≥14 years old, who suffered severe head injuries and were treated at the University Hospital of Getafe, between 2005 and 2015 (n = 66). Our aims were (1) to examine patients' epidemiological profile; (2) to describe the best diagnostic and therapeutic measures performed; and (3) to identify the main determinants of final outcome. Methods: This was a combined retrospective and prospective study, consisting first of a review of medical records, followed by in-house neurosurgical consultations to determine final outcomes. Results: In this study, the variables that were most determinant of poor outcomes in patients with severe head injuries were patient age, the initial size and reactivity of their pupils, their worst Glasgow Coma Scale score, and lesions found on brain computed tomography (CT). Conclusions: Severe head injuries can be categorized into nine pathological patterns, based upon brain CT findings. Each pattern has a distinct anatomical and clinical profile and well-defined prognostic significance, in turn associated with behavior patterns characteristic of intracranial pressure (ICP). Pure extra-axial hematomas are associated with the best prognosis, with diffuse axonal lesions associated with brain swelling and multiple bilateral contusions the worst. The Rimel Scale accurately adjusts to the severity of head trauma. The Glasgow Coma Scale is a good predictor of ultimate outcomes in patients with severe head injuries.
