Craniectomías descompresivas en el traumatismo craneoencefálico: la visión del intensivista / Decompressive craniectomy in traumatic brain injury: the intensivist's point of view

Objetivo Realizar una escala con parámetros clínicos y radiológicos precoces tras un TCE que identifique a los enfermos que en su evolución posterior van a someterse a una CD. Método Estudio observacional de una cohorte retrospectiva de pacientes que tras un TCE ingresan en la Sección de Neurocríticos del Servicio de Medicina Intensiva de nuestro hospital durante un periodo de 5 años (2014-2018). Detección de variables clínicas y radiológicas y creación de todos los modelos posibles con las variables significativas, clínicamente relevantes y de fácil detección precoz. Selección del que presentaba valores más bajos de criterios de información bayesiano y de Akaike para la creación de la escala. Calibración y validación interna mediante la prueba de bondad de ajuste de Hosmer-Lemeshow y análisis bootstrapping con 1.000 re-muestreos. Resultados Se realizaron 37 CD en 153 enfermos que ingresaron tras un TCE. El modelo final resultante incluía desviación de línea media, GCS y colapso ventricular con un área bajo la curva ROC de 0,84 (IC95% 0,78-0,91) y Hosmer-Lemeshow p=0,71. La escala desarrollada detectaba bien a los enfermos que iban a precisar una CD precoz (en las primeras 24horas) tras un TCE (2,5±0,5) pero no a aquellos que la necesitarían en una fase más tardía de su enfermedad (1,7±0,8). Sin embargo, parece prevenirnos sobre los enfermos que si bien no precisan inicialmente una CD sí tienen probabilidades de necesitarla posteriormente en su evolución (CD tardía vs. no precisan CD, 1,7±0,8 vs. 1±0,7; p=0,002). Conclusión Hemos desarrollado una escala pronóstica que permite detectar en nuestro medio, con una buena sensibilidad y especificidad y usando criterios clínico-radiológicos precoces, aquellos pacientes que tras un TCE van a precisar una CD (AU)

Objetive To perform a score with early clinical and radiological findings after a TBI that identifies the patients who in their subsequent evolution are going to undergo DC. Method Observational study of a retrospective cohort of patients who, after a TBI, enter the Neurocritical Section of the Intensive Care Unit of our hospital for a period of 5 years (2014-2018). Detection of clinical and radiological criteria and generation of all possible models with significant, clinically relevant and easy to detect early variables. Selection of the one with the lowest Bayesian Information Criterion and Akaike Information Criterion values for the creation of the score. Calibration and internal validation of the score using the Hosmer-Lemeshow and a bootstrapping analysis with 1,000 re-samples respectively. Results 37 DC were performed in 153 patients who were admitted after a TBI. The resulting final model included Cerebral Midline Deviation, GCS and Ventricular Collapse with an Area under ROC Curve: 0.84 (95% IC 0.78-0.91) and Hosmer-Lemeshow p=0.71. The developed score detected well those patients who were going to need an early DC (first 24hours) after a TBI (2.5±0.5) but not those who would need it in a later stage of their disease (1.7±0.8). However, it seems to advice us about the patients who, although not requiring an early DC are likely to need it later in their evolution (DC after 24hours vs do not require DC, 1.7±0.8 vs 1±0.7; p=0.002). Conclusion We have developed a prognostic score using early clinical-radiological criteria that, in our environment, detects with good sensitivity and specificity those patients who, after a TBI, will require a DC (AU)

Supra and infratentorial massive strokes in previously healthy young patients with SARS-CoV-2. The role of neurosurgery / Ictus masivos supra e infratentoriales en pacientes jóvenes previamente sanos con SARS-CoV-2. El rol de la neurocirugía

The coronavirus disease 2019 (COVID-19) has amazed by its distinct forms of presentation and severity. COVID-19 patients can develop large-scale ischemic strokes in previously healthy patients without risk factors, especially in patients who develop an acute respiratory distress syndrome (SARS-CoV-2). We hypothesize that ischemic events are usually the result of the combined process of a pro-inflammatory and pro-coagulant state plus vascular endothelial dysfunction probably potentiated by hypoxia, hemodynamic instability, and immobilization, as reported in other cases. To the best of our knowledge, we report the first case of partial obstruction of a vertebral artery in a patient with COVID-19. Decompressive surgery remains a life-saving maneuver in these patients (as in other non-COVID-19 strokes) and requires further investigation (AU)

La enfermedad por coronavirus 2019 (COVID-19) ha sorprendido por sus distintas formas de presentación y gravedad. Los pacientes con COVID-19 pueden desarrollar accidentes cerebrovasculares isquémicos a gran escala, incluso aquellos previamente sanos, sin factores de riesgo, y especialmente los que desarrollan un síndrome de dificultad respiratoria aguda (SARS-CoV-2). Presumimos que los eventos isquémicos son generalmente el resultado del proceso combinado de un estado proinflamatorio y procoagulante, más una posible disfunción endotelial vascular, probablemente potenciada por hipoxia, inestabilidad hemodinámica e inmovilización, como se ha reportado en otros casos. Hasta nuestro conocimiento reportamos el primer caso de una obstrucción parcial de una arteria vertebral en un paciente con COVID-19. La cirugía descompresiva sigue siendo una maniobra que salva vidas (como en otros accidentes cerebrovasculares que no están relacionados con la COVID-19) y requiere más investigación (AU)
