RESUMO
Acute fulminant cerebral edema is a type of rapidly progressive encephalitis that occurs in children and is associated with significant morbidity and mortality. We present a clinical case with seizures, rapid neurological deterioration and the early appearance of cerebral herniation signs. Although the radiological tests were initially normal and there are no established parameters that predict the evolution of encephalitis to a rapidly progressive subtype, the clinical evolution forced to consider the decompressive craniectomy due to the lack of response to the medical management of the cerebral edema. It may be necessary take a brain biopsy to confirm the etiology of the encephalitis origin of acute fulminant cerebral edema. The objective of surgery should be not only to increase survival, but also to reduce subsequent neurological sequelae.
RESUMO
INTRODUCTION: Bone flap replacement after a decompressive craniectomy is a low complexity procedure, but with complications that can negatively impact the patient's outcome. A better knowledge of the risk factors for these complications could reduce their incidence. PATIENTS AND METHODS: A retrospective review of a series of 50 patients who underwent bone replacement after decompressive craniectomy at a tertiary center over a 10-year period was performed. Those clinical variables related to complications after replacement were recorded and their risk factors were analyzed. RESULTS: A total of 18 patients (36%) presented complications after bone flap replacement, of which 10 (55.5%) required a new surgery for their treatment. Most of the replacements (95%) were performed in the first 90 days after the craniectomy, with a tendency to present more complications compared to the subsequent period (37.8% vs 20%, pâ¯>â¯0.05). The most frequent complication was subdural hygroma, which appeared later than infection, the second most frequent complication. The need for ventricular drainage or tracheostomy and the mean time on mechanical ventilation, ICU admission, or waiting until bone replacement were greater in patients who presented post-replacement complications. Previous infections outside the nervous system or the surgical wound was the only risk factor for post-bone flap replacement complications (pâ¯=â¯0.031). CONCLUSIONS: Postoperative complications were recorded in more than a third of the patients who underwent cranial bone flap replacement, and at least half of them required a new surgery. A specific protocol aimed at controlling previous infections could reduce the risk of complications and help establish the optimal time for cranial bone flap replacement.

Resumen El nuevo síndrome respiratorio agudo severo por coronavirus tipo 2 (SARS-CoV-2) que causa la enfermedad por COVID-19, se detectó por primera vez en diciembre de 2019. En donde se ha visto que existe un estado protrombótico con afección al sistema nervioso central, con afectación a vasos de gran calibre como la arteria cerebral media, se debe a mecanismos inducidos por la propia infección, estado de hipercoagulabilidad y daño endotelial. Las manifestaciones neurológicas en el COVID-19 se encuentran en el 36% de los pacientes. Descripción del caso: Se trata de un paciente del sexo masculino, de 36 años de edad, con fiebre, tos y malestar general, a quien se le realizó una prueba COVID que resultó positiva, con empeoramiento del cuadro al que se agregó fotofobia, hemiparesia derecha y desviación de la comisura labial hacia la izquierda, por lo que fue llevado a un facultativo 8 horas después del inicio del cuadro clínico. Ahí se realizó una tomografía de cráneo simple que evidenció infarto extenso de la arteria cerebral media izquierda, con edema cerebral maligno, el cual se derivó a manejo quirúrgico de urgencia donde se le realizó una craniectomía descompresiva izquierda extensa. Después de esto, se mantuvo con asistencia respiratoria por intubación mecánica y medidas antiedema cerebral, y se logró que hubiera progresión ventilatoria; sin embargo, se le realizó traqueostomía y gastrostomía por presentar malos predictores de extubación. Se mantuvo en observación posquirúrgica y quedó con hemiparesia 3/5 derecha, sin algún otro déficit, por lo que se dio egreso a domicilio. Discusión: El caso presentado fue manejado con craniectomía descompresiva extensa, y se obtuvo mejoría en la supervivencia y pronóstico funcional, al igual que lo reportado en la literatura médica, en donde se recomienda que dicho manejo se realice de forma temprana. Conclusiones: El presente informe nos revela que aquellos pacientes hombres jóvenes en la cuarta y quinta década de la vida, con COVID-19 e infarto de arteria cerebral media, se presentan sin comorbilidades al darse tratamiento temprano con hemicraniectomía descompresiva, el cual mejora su pronóstico de vida, concordando con los casos presentados en la literatura médica.
Abstract The new severe acute respiratory syndrome due to coronavirus type 2 (SARS-CoV-2), which causes COVID-19 disease, was detected for the first time in December 2019. Where it has been seen that there is a prothrombotic state with involvement of the Central Nervous, with involvement of large vessels such as the middle cerebral artery, is due to mechanisms induced by the infection itself, hypercoagulable state and endothelial damage. Neurological manifestations in COVID-19 are found in 36% of patients. Case description: This is a 36-year-old male patient with fever, cough and general malaise. A COVID test was performed, which came out positive. His condition was getting worse adding photophobia, right hemiparesis and deviation of the corner of the mouth to the left, which is why he went to the doctor, arriving 8 hours after the onset of the clinical picture, where a simple skull tomography was performed, showing extensive infarction of the left middle cerebral artery with malignant cerebral edema. He was transferred to emergency surgical management where a left decompressive craniectomy was performed. After this, mechanical respiratory assistance with intubation and anti-cerebral edema measures were maintained, achieving ventilatory progression; however, a tracheostomy and gastrostomy were performed due to poor predictors of extubation. He was kept under post-surgical observation, leaving him with 3/5 right hemiparesis, without any other deficit, therefore, he was discharged home. Discussion: The case presented was managed with decompressive craniectomy, resulting in an improvement in survival, as reported in the literature where it is recommended that such management should be performed early. Conclusions: This report reveals that patients with COVID-19 present in young men in the fourth and fifth decade of life, without comorbidities, that recieved early treatment with decompressive hemicraniectomy, improved their life prognosis, consistent with the cases presented in the literature.
RESUMO
Introduction: Despite the highly favorable prognosis, mortality occurs in nearly 2% of patients with cerebral venous thrombosis (CVT), in which decompressive craniectomy (DC) may be the only way to save the patient's life. The aim of this report is to describe the risk factors, neuroimaging features, in-hospital complications and functional outcome of severe CVT in patients treated with DC. Materials and methods: Consecutive malignant CVT cases treated with DC from a retrospective third-level hospital database were analyzed. Demographic, clinical, and functional outcomes were analyzed. Results: Twenty-six patients were included (20 female, age 35.4 ± 12.1 years); 53.8% of the patients had acute CVT, with neurological focalization as the most common symptom in 92.3% of the patients. Superior sagittal sinus thromboses were found in 84.6% of cases. Bilateral lesions were present in 10 patients (38.5%). Imaging on admission showed a parenchymal lesion (venous infarction ± hemorrhagic lesion) > 6 cm measured along the longest diameter in 25 patients (96.2%). Mean duration of clinical neurological deterioration was 3.5 days; eleven patients (42.3%) died during hospitalization. Conclusion: In patients with severe forms of CVT, we found higher mortality than previously reported. DC is an effective life-saving treatment with acceptable functional prognosis for survivors.(AU)
Introducción: A pesar del pronóstico favorable en pacientes con trombosis venosa cerebral (TVC), cerca de un 2% de estos pacientes fallecen, para los cuales la craniectomía descompresiva (CD) puede ser una opción terapéutica. El objetivo de este artículo es describir los factores de riesgo, las características de las neuroimágenes, complicaciones hospitalarias y evolución funcional, de pacientes con TVC severa tratados con CD. Materiales y métodos: Se analizaron características demográficas, clínicas y funcionales de casos consecutivos de TVC severa tratados con CD, a partir de una base de datos retrospectiva de un hospital de tercer nivel. Resultados: Veintiséis pacientes fueron incluidos (20 mujeres, media de edad 35,4 ±12,1 años); un 53,8% de los pacientes presentaron una TVC aguda, con manifestaciones neurológicas focales como el síntoma más frecuente en el 92,3% de los casos. La trombosis del seno sagital superior estuvo presente en el 84,6% y se presentaron lesiones bilaterales parenquimatosas en 10 pacientes (38,5%). La imagen al ingreso demostró lesiones parenquimatosas (infarto venoso ± lesión hemorrágica) > 6 cm (medida en el mayor diámetro de la misma), en 25 pacientes (96,2%). La duración media del deterioro neurológico fue de 3,5 días; 11 pacientes (42,3%) murieron durante la hospitalización. Conclusión: En pacientes con formas severas de TVC encontramos una mayor mortalidad que la publicada previamente; la CD podría ser una opción terapéutica en ese grupo de pacientes.(AU)

Abstract Background Ischemic stroke is an important cause of death in the world. The malignant middle cerebral artery infarction (MMCAI) has mortality as high as 80% when clinically treated. In this setting, decompressive craniectomy is a life-saving measure, in spite of high morbidity among survivors. Objective To evaluate the outcomes of patients with MMCAI treated with decompressive craniectomy in a Brazilian academic tertiary stroke center. Methods A prospective stroke database was retrospectively evaluated, and all patients treated with decompressive craniectomy for MMCAI between January 2014 and December 2017 were included. The demographics and clinical characteristics were evaluated. The functional outcome, measured by the modified Rankin Scale (mRS), was assessed at hospital discharge, after 3-months and 1-year of follow-up. Results We included 53 patients on the final analysis. The mean age was 54.6 ± 11.6 years and 64.2% were males. The median time from symptoms to admission was 4.8 (3-9.7) hours and the mean time from symptoms to surgery was 36 ± 17 hours. The left hemisphere was the affected in 39.6%. The median NIHSS at admission was 20 (16-24). The in-hospital mortality was 30.2%. After a median of 337 [157-393] days, 47.1% of patients had achieved favorable outcome (mRS ≤ 4) and 39.6% had died. Conclusion Decompressive craniectomy is a life-saving measure in the setting of MMCAI, and its effects remains important in the scenario of a middle-income country in real-world situations.

RESUMO
The widespread use of decompressive craniectomy and subsequent cranioplasty has led to a better understanding of its complications. However, cases of a sunken bone flap have hardly ever been described. We present the eighth case reported up to date and perform a review of the literature of this sporadic complication. A 40-year-old Caucasian male suffered a traumatic brain injury that required a decompressive craniectomy. One month after initial trauma autologous cranioplasty was performed. A ventriculoperitoneal shunt was also placed. Neurological status progressively improved but his therapist noted cognitive status decline 8 months later. Follow-up computed tomography showed a progressive sinking bone flap. The patient underwent bone flap removal and a custom-made calcium phosphate-based implant was inserted, leading to symptoms resolution. Bone resorption has been described as the main cause of sinking bone flap following cranioplasty. This entity may manifest with symptoms of overdrainage in patients with cerebrospinal fluid shunt devices (AU)
El uso extendido de la craniectomía descompresiva y la consiguiente craneoplastia ha propiciado un mejor conocimiento de sus complicaciones. Sin embargo, esporádicamente se han descrito casos de hundimiento del colgajo óseo. Describimos el octavo caso descrito hasta la fecha y realizamos una revisión de la literatura de esta infrecuente complicación. Un varón de 40 años sufrió un traumatismo craneoencefálico que requirió craniectomía descompresiva. Un mes después se sometió a la reposición de su colgajo óseo, junto con la implantación de una derivación ventriculoperitoneal. Presentó mejoría neurológica progresiva que se frenó y empeoró ocho meses después. La tomografía computarizada de control mostró hundimiento progresivo del colgajo óseo. El paciente se sometió a la retirada del colgajo óseo y cranioplastia con implante a medida, con resolución de los síntomas. La resorción ósea se ha descrito como la principal causa del hundimiento del colgajo óseo tras cranioplastia. Sin embargo, esta entidad puede manifestarse como síntomas de sobredrenaje en pacientes con derivación de líquido cefalorraquídeo (AU)

Introducción: El aumento de la presión intracraneal se ha asociado a un pronóstico neurológicodesfavorable y a un incremento en la mortalidad en pacientes con traumatismo craneoencefálico grave. Tradicionalmente, las terapias para disminuir la presión intracraneal se administranutilizando un enfoque progresivo, reservando el uso de opciones más agresivas para los casossin respuesta a intervenciones de primer nivel, o de hipertensión intracraneal refractaria. Desarrollo: El valor terapéutico de las intervenciones de rescate para la hipertensión intracraneal, así como el momento adecuado para su uso ha sido debatido constantemente en laliteratura. En esta revisión, discutiremos las principales opciones de tratamiento para la hipertensión intracraneal refractaria posterior a un traumatismo craneoencefálico grave en adultos.Tenemos la intención de llevar a cabo una revisión en profundidad de los ensayos controladosaleatorios más representativos sobre las diferentes intervenciones terapéuticas de rescate,incluyendo la craniectomía descompresiva, hipotermia terapéutica y barbitúricos. Además,discutiremos las perspectivas futuras de estas opciones de tratamiento. Conclusiones: La evidencia parece mostrar que se puede reducir la mortalidad al utilizar estasintervenciones de rescate como terapia de último nivel, sin embargo, este beneficio vieneacompanado de una discapacidad severa. La decisión de realizar o no estas intervencionesdebe ser individualizada y centrada en el paciente. El desarrollo e integración de diferentesvariables fisiológicas a través de monitorización multimodal es de suma importancia para poderproporcionar información pronóstica más sólida a los pacientes que enfrentan este tipo dedecisiones.(AU)
Introduction: Increased intracranial pressure has been associated with poor neurological out-comes and increased mortality in patients with severe traumatic brain injury. Traditionally,intracranial pressure-lowering therapies are administered using an escalating approach, withmore aggressive options reserved for patients showing no response to first-tier interventions,or with refractory intracranial hypertension. Development: The therapeutic value and the appropriate timing for the use of rescue treat-ments for intracranial hypertension have been a subject of constant debate in literature. Inthis review, we discuss the main management options for refractory intracranial hypertensionafter severe traumatic brain injury in adults. We intend to conduct an in-depth revision of themost representative randomised controlled trials on the different rescue treatments, includingdecompressive craniectomy, therapeutic hypothermia, and barbiturates. We also discuss futureperspectives for these management options. Conclusions: The available evidence appears to show that mortality can be reduced whenrescue interventions are used as last-tier therapy; however, this benefit comes at the cost ofsevere disability. The decision of whether to perform these interventions should always bepatient-centred and made on an individual basis. The development and integration of differentphysiological variables through multimodality monitoring is of the utmost importance to providemore robust prognostic information to patients facing these challenging decisions.(AU)

INTRODUCTION: Increased intracranial pressure (ICP) has been associated with poor neurological outcomes and increased mortality in patients with severe traumatic brain injury (TBI). Traditionally, ICP-lowering therapies are administered using an escalating approach, with more aggressive options reserved for patients showing no response to first-tier interventions, or with refractory intracranial hypertension. DEVELOPMENT: The therapeutic value and the appropriate timing for the use of rescue treatments for intracranial hypertension have been a subject of constant debate in literature. In this review, we discuss the main management options for refractory intracranial hypertension after severe TBI in adults. We intend to conduct an in-depth revision of the most representative randomised controlled trials on the different rescue treatments, including decompressive craniectomy, therapeutic hypothermia, and barbiturates. We also discuss future perspectives for these management options.

Abstract Background Brain edema is the leading cause of death in patients with malignant middle cerebral artery (MCA) infarction. Midline shift (MLS) has been used as a monohemispheric brain edema marker in several studies; however, it does not precisely measure brain edema. It is now possible to directly measure hemisphere brain volume. Knowledge about the time course of brain edema after malignant middle cerebral artery infarction may contribute to the condition's management. Objective Therefore, our goal was to evaluate the course of brain edema in patients with malignant MCA infarction treated with decompressive craniectomy (DC) using hemispheric volumetric measurements. Methods Patients were selected consecutively from a single tertiary hospital between 2013 and 2019. All patients were diagnosed with malignant middle cerebral artery infarction and underwent a decompressive craniectomy (DC) to treat the ischemic event. All computed tomography (CT) exams performed during the clinical care of these patients were analyzed, and the whole ischemic hemisphere volume was calculated for each CT scan. Results We analyzed 43 patients (197 CT exams). Patients' mean age at DC was 51.72 [range: 42-68] years. The mean time between the ischemic ictus and DC was 41.88 (range: 6-77) hours. The mean time between the ischemic event and the peak of hemisphere volume was 168.84 (95% confidence interval [142.08, 195.59]) hours. Conclusion In conclusion, the peak of cerebral edema in malignant MCA infarction after DC occurred on the 7th day (168.84 h) after stroke symptoms onset. Further studies evaluating therapies for brain edema even after DC should be investigated.
Resumo Antecedentes O edema cerebral é a principal causa de morte em pacientes com infarto maligno de artéria cerebral média. O desvio da linha média tem sido utilizado como marcador de edema cerebral mono-hemisférico em alguns estudos; porém, ele não mede de forma precisa o edema cerebral. Atualmente é possível mensurar diretamente o volume do hemisfério cerebral. O conhecimento sobre a evolução temporal do edema cerebral após infartos malignos da artéria cerebral média pode contribuir para o cuidado clínico desta condição. Objetivo Nosso objetivo é avaliar o edema hemisférico ao longo do tempo, em pacientes com infarto maligno da artéria cerebral média, tratados com craniectomia descompressiva. Métodos Os pacientes foram selecionados de forma consecutiva, em um hospital terciário, entre 2013 e 2019. Todos os pacientes apresentavam diagnóstico de infarto maligno de artéria cerebral média e foram submetidos a craniectomia descompressiva. Todas as tomografias computadorizadas de crânio destes pacientes foram analizadas, e o volume do hemisfério cerebral infartado foi mensurado. Resultados Analisamos 43 pacientes (197 tomografias de crânio). A idade média dos pacientes na craniectomia descompressiva foi 51,72 (42-68) anos. O tempo médio entre o ictus e a craniectomia descompressiva foi 41,88 (6-77) horas. O tempo médio entre o ictus e o pico do volume hemisférico foi 168,84 (142,08-195,59) horas. Conclusão O pico do volume cerebral em pacientes com infarto maligno de artéria cerebral média submetidos a craniectomia descompressiva ocorreu no 7o dia (168,84 horas) após o infarto. Mais estudos avaliando terapêuticas direcionadas ao edema cerebral seriam úteis neste contexto.

ABSTRACT This study aimed to characterize clinical-neurological factors and the functional swallowing capacity of patients with malignant infarction submitted to decompressive craniectomy during the hospital stay. This retrospective, descriptive, observational study was conducted between January 2020 and December 2021. The following data regarding up to eight stages were extracted for descriptive analysis: age, location of the lesion, level of awareness according to the Glasgow Coma Scale, neurological impairment according to the National Institutes of Health Stroke Scale, and the functional swallowing capacity according to the Functional Oral Intake Scale. Data on five patients were collected, with a mean of 0.2 days for the first neurological assessment. Decompressive craniectomy was performed in a mean of 2 days after admission. The speech-language-hearing assessment occurred in a mean of 8.2 days, and the speech-language-hearing discharge took a mean of 35.4 days. The neurological impairment score remained the same as in the first neurological assessment after decompressive craniectomy, with a mean score of 16.6. The functional swallowing capacity was the same in the first assessment after decompressive craniectomy, on FOIS level 1, improving considerably by the discharge, with a mean level of 4.8. It is concluded that clinical-neurological factors can interfere with the functional swallowing capacity, although they did not hinder either speech-language-hearing treatment or their evolution to a full oral diet during the hospital stay.
RESUMO O objetivo do presente trabalho é caracterizar fatores clínicos-neurológicos e capacidade funcional de deglutição de pacientes com Acidente Vascular Cerebral Isquêmico Maligno submetidos a craniectomia descompressiva durante internação hospitalar. Trata-se de um estudo observacional, descritivo e retrospectivo, realizado de janeiro de 2020 a dezembro de 2021. Os dados foram extraídos em até oito momentos, incluindo idade, local da lesão, nível de consciência de acordo com Glasgow, comprometimento neurológico pelo National Institutes of Health Stroke Scale e capacidade funcional de deglutição pela Escala Funcional de Ingestão por Via Oral. Realizou-se análise descritiva. Foram coletados dados de 5 pacientes sendo a média de tempo para primeira avaliação neurológica de 0,2 dias. A realização da craniectomia descompressiva levou em média 2 dias após admissão. Avaliação fonoaudiológica ocorreu, em média, 8,2 dias e alta fonoaudiológica levou, em média, 35,4 dias. O comprometimento neurológico manteve-se na pontuação da primeira avaliação neurológica pós-craniectomia descompressiva, média de 16,6. A capacidade funcional de deglutição foi a mesma na primeira avaliação pós-craniectomia descompressiva, com nível 1 na FOIS, melhorando consideravelmente, com média de nível 4,8, na alta. Concluiu-se que fatores clínicos-neurológicos podem interferir na capacidade funcional de deglutição, contudo não limitaram a atuação fonoaudiológica e evolução com dieta oral exclusiva na internação hospitalar.
RESUMO
BACKGROUND: Cranioplasty is the used method in neurosurgery for repairing cranial bone defects. In our environment, the most widely used material is cryopreserved autologous bone (ABCp). OBJECTIVE: A retrospective observational study was proposed in order to analyze complications in patients who underwent decompressive craniectomy for brain trauma, with subsequent cranioplasty with ABCp. METHOD: Patients who underwent cranioplasties with consecutive ABCp performed at our institution over a four-year period (2016-2019) with subsequent follow-up were included, collecting multiple variables in relation to the appearance of complications. RESULTS: 113 cranioplasties were performed, of which 85.8% (n = 97) were performed with ABCp. Mainly with frontotemporoparietal bone defect (94.84%) performed late (> 3 months) in 91.76%. The complication rate was 16.49%, the most significant being the infection of the surgical site (n = 8, 8.24%), the presence of intracranial hematoma (n = 3, 3.09%) and the reabsorption of the autologous bone (n = 2, 2.06%), meriting surgical management in nine of them (9.27%). CONCLUSIONS: ABCp is a valid and safe option, which meets the basic characteristics to consider it the ideal material, with an acceptable rate of complications, biocompatible, with osteogenic potential, adequate protection of the brain and decrease in surgery costs.
ANTECEDENTES: La craneoplastia es el método utilizado en neurocirugía para reparar los defectos óseos craneanos. En nuestro medio, el material utilizado mayormente es el hueso autólogo criopreservado (HACp). OBJETIVO: Realizamos un estudio retrospectivo observacional para analizar las complicaciones en pacientes sometidos a craniectomía descompresiva por trauma craneoencefálico y realización de craneoplastia con HACp. MÉTODO: Se incluyeron pacientes que fueron sometidos a craneoplastias con HACp consecutivas realizadas en un periodo de 4 años (2016-2019) con seguimiento posterior, recabando múltiples variables en relación con la aparición de complicaciones. RESULTADOS: Se realizaron 113 craneoplastias, de las cuales el 85.8% (n = 97) fueron realizadas con HACp, principalmente con defecto óseo frontotemporoparietal (94.84%), realizadas de forma tardía (> 3 meses) en el 91.76%. El índice de complicaciones fue del 16.49%, siendo las más significativas la infección del sitio quirúrgico (n = 8, 8.24%), la presencia de hematoma endocraneano (n = 3, 3.09%) y la reabsorción del hueso autólogo (n = 2, 2.06%), ameritando manejo quirúrgico en nueve ocasiones (9.27%). CONCLUSIONES: El HACp es una opción válida y segura, la cual cumple con las características para considerarlo el material ideal, con un aceptable índice de complicaciones, biocompatible, con potencial osteogénico, adecuada protección encefálica y disminución de los costos de la cirugía.

Abstract Background After a case of stroke, intracranial pressure (ICP) must be measured and monitored, and the gold standard method for that is through an invasive technique using an intraventricular or intraparenchymal device. However, The ICP can also be assessed through a non-invasive method, comprised of the measurement of the optic nerve sheath diameter (ONSD) through ultrasound (US). Objective To evaluate the ICP of patients who underwent wide decompressive craniectomy after middle cerebral artery (MCA) infarction via preoperative and postoperative ONSD measurements. Methods A total of 17 patients, aged between 34 and 70 years, diagnosed with malignant MCA infarction with radiological edema and mid-line shift, who underwent decompressive surgery, were eligible. From the records, we collected data on age, sex, preoperative and postoperative Glasgow Coma Scale (GCS) scores, National Institutes of Health Stroke Scale (NIHSS) score, the degree of disability in the preoperative period and three months postoperatively through the scores on the Modified Rankin Scale (MRS), and the preoperative and postoperative midline shift measured by computed tomography (CT) scans of the brain. Results Preoperatively, the mean GCS score was of 8 (range: 7.7-9.2), whereas it was found to be of 12 (range 10-14) on the first postoperative day (p = 0.001). The mean preoperative NIHSS score was of 21.36 ± 2.70 and, on the first postoperative day, it was of 5.30 ± 0.75 (p < 0.001). As for the midline shift, the mean preoperative value was of 1.33 ± 0.75 cm, and, on the first postoperative day, 0.36 ± 0.40 cm (p < 0.001). And, regarding the ONSD, the mean preoperative measurement was of 5.5 ± 0.1 mm, and, on the first postoperative day, it was of 5 ± 0.9 mm (p < 0.001). Conclusion The ocular US measurement of the ONSD for the preoperative and postoperative monitoring of the ICP seems to be a practical and useful method.
Resumo Antecedentes Após um acidente vascular cerebral (AVC), a pressão intracraniana (PIC) deve ser medida e monitorada, e o método padrão-ouro para isso é um procedimento invasivo por meio de um dispositivo intraventricular ou intraparenquimal. No entanto, a PIC também pode ser avaliada por um método não invasivo, composto da medida do diâmetro da bainha do nervo óptico (DBNO) por ultrassom (US). Objetivo Avaliar a PIC de pacientes submetidos a craniectomia descompressiva ampla após infarto da artéria cerebral média (ACM) por meio das medidas do DBNO nos períodos pré e pós-operatório. Métodos Um total de 17 pacientes, com idades entre 34 e 70 anos, diagnosticados com infarto maligno da ACM com edema radiológico e deslocamento da linha média, e que foram submetidos a cirurgia descompressiva, eram elegíveis. A partir dos prontuários, coletamos informações relativas à idade, gênero, pontuações pré e pósoperatória na Escala de Coma de Glasgow (ECG), pontuação na escala de AVC dos National Institutes of Health (NIH), o grau de incapacidade no pré-operatório e após três meses da operação pelas pontuações na Escala de Rankin Modificada (ERM), e o desvio da linha média no pré e pós-operatório medido por tomografia computadorizada (TC) cerebral. Resultados No pré-operatório, a pontuação média na ECG foi de 8 (variação: 7,7-9,2), e, no primeiro dia do pós-operatório, 12 variação 10-14) (p = 0,001). A pontuação média na escala dos NIH foi de 21,36 ± 2,70 no pré-operatório, e de 5,30 ± 0,75 no primeiro dia de pós-operatório (p < 0,00 1). Quanto ao desvio da linha média, no préoperatório ele teve uma média de 1,33 ± 0,75 cm, e de 0,36 ± 0,40 cm no primeiro dia de pós-operatório (p < 0,001). E o DBNO apresentou uma média pré-operatória de 5,5 ± 0,1 mm, e de 5 ± 0,9 mm no primeiro dia de pós-operatório (p < 0,001). Conclusão A mensuração ocular do DBNO por US para o monitoramento da PIC no pré e no pós-operatório parece ser um método prático e útil.
RESUMO
INTRODUCTION: Traumatic brain injury (TBI) is one of the leading causes of death and disability globally. We present a study describing epidemiological changes in severe TBI and the impact these changes have had on management and analysing alternatives that may improve outcomes in this new population. MATERIALS AND METHODS: We performed a retrospective, descriptive, cross-sectional analysis of patients presenting severe TBI at our hospital in the period of 1992-1996 and 2009-2013. We analysed demographic data, including age, sex, mortality, aetiology, anticoagulation, treatment, and functional outcome. RESULTS: We reviewed data from 220 patients. In the second cohort, there were 40% fewer patients, mean age was 12 years older, patients were more frequently receiving anticoagulation therapy, and the percentage of interventions was halved. Aetiology varied, with traffic accidents being the main cause in the first group, and accidental falls and being hit by cars in the second group. There were no intergroup differences for mortality or functional outcomes. CONCLUSION: The age of patients admitted due to severe TBI has increased. As a result of this, the main cause of severe TBI in our population is accidental falls in elderly, anticoagulated patients. Despite the low-energy nature of trauma, patients in the second cohort presented a poorer baseline status, and were less frequently eligible for surgery, with no improvement in mortality or functional outcomes.

Introducción: El TCE es una de las principales causas de muerte y discapacidad a nivel mundial. Presentamos este estudio con el objetivo de detallar el cambio epidemiológico de la población que sufre TCE severo, su influencia en el tipo de tratamiento ofrecido y analizar alternativas que mejoren los resultados ante el nuevo tipo de población que afrontamos. Material y métodos: Se ha realizado un análisis descriptivo, transversal y retrospectivo de los pacientes que sufrieron TCE severo en nuestro hospital en los periodos 1992-1996 y 2009-2013. Se analizaron datos demográficos como edad, sexo, mortalidad, etiología, anticoagulación, tratamiento realizado y resultados funcionales. Resultados: Se revisaron 220 pacientes. En la segunda cohorte el número de pacientes con TCE severo disminuyó un 40%, eran de media 12 años mayores, más frecuentemente anticoagulados y las intervenciones se redujeron a la mitad. Varió la etiología, predominando en el primer grupo los accidentes de tráfico y en el segundo las caídas casuales y los atropellos. No hubo diferencias en la mortalidad de ambos grupos, y sí en su situación funcional. Conclusión: En este estudio encontramos un envejecimiento de la población que ingresa por TCE severo. Ello hace que, en la actualidad, la principal causa de TCE severo en nuestra población sean las caídas casuales en pacientes anticoagulados mayores. A pesar de ser traumatismos de poca energía, los pacientes presentan peores condiciones basales y son menos candidatos a cirugía, sin que mejoren la mortalidad ni la situación funcional. (AU)

Antecedentes: Los infartos cerebelosos suponen una entidad rara con una incidencia baja del total de ictus isquémicos. El territorio más prevalente de los infartos cerebelosos son los de la arteria cerebelosa posterior inferior (PICA). Cuando los infartos se limitan al cerebelo, los pacientes típicamente experimentan síntomas no específicos, esto hace considerar otros diagnósticos de forma errónea. Descripción del caso clínico: paciente femenina de 54 años, con antecedente de hipertensión arterial, quien presentaba cefalea insidiosa y progresiva acompañado de vértigo, alteración en la marcha y deterioro progresivo del estado de conciencia. Se realizó imagen de Resonancia Magnética Cerebral (IRM), la cual reveló zonas hiper intensas bilaterales en región cerebelosa que delimitaban territorio vascular de la arteria cerebelosa posterior inferior además dilatación moderada del sistema ventricular. Fue intervenida quirúrgicamente, realizándose craniectomía suboccipital descompresiva; posterior a la cirugía presentó mejoría clínica. Conclusiones: El ictus isquémico cerebeloso bilateral es una forma infrecuente de ictus y su presentación clínica es muy diversa. El desarrollo de las neuroimágenes, juegan un papel importante para ayudar a los médicos a seleccionar el tratamiento adecuado. Alrededor de la mitad de los pacientes con infartos cerebelosos que presentan deterioro neurológico progresivo y son tratados con craniectomía suboccipital descompresiva tienen buenos resultados. El pilar fundamental de este caso fue el hacer un diagnóstico temprano de esta entidad, ya que permitió prevenir las posibles complicaciones graves asociadas al infarto cerebeloso, las cuales ocurren durante la primera semana del ictus y, por lo tanto, asegurar un pronóstico favorable para el paciente...(AU)

RESUMO
Background Decompressive craniectomy is a consolidated method for the treatment of malignant ischemic stroke (iS) in the territory of the middle cerebral artery. Thus, factors contributing to mortality constitute an important area of investigation. Objective To evaluate the epidemiological clinical profile and predictors of mortality in a single-center population of patients undergoing decompressive craniectomy for the treatment of malignant iS. Methods A single-center retrospective study was performed in 87 patients with malignant iS subjected to emergency decompressive craniectomy from January 2014 to December 2017. Age, gender, laterality, aphasia, time interval between disease onset and treatment, and clinical and neurological outcomes using the Glasgow coma scale were assessed. The patients were stratified by age: a group of participants 60 years old or younger, and a group of participants older than 60 years old for assessment of survival and mortality by the Kaplan-Meier test and log-rank comparison. The intensity of the association between demographic and clinical variables was evaluated by multivariate Cox regression. Results Ischemic stroke was prevalent in patients with hypertension (63.29%). Seventy seven (84%) patients had some type of postoperative complication, mostly pneumonia (42.8%). The risk of death was 2.71 (p » 0.0041) and 1.93 (p » 0.0411) times higher in patients older than 60 and with less than 8 points on the Glasgow coma scale, respectively. Conclusion Malignant iS has a significant mortality rate. Age above 60 years and Glasgow coma scale values below 8 were statistically correlated with unfavorable prognosis.
Contexto A craniectomia descompressiva é um método consolidado para o tratamento do acidente vascular cerebral isquêmico (AVCI) maligno no território da artéria cerebral média. No entanto, os fatores envolvidos na mortalidade constituem objeto de investigação. Objetivo Avaliar o perfil clínico epidemiológico e os preditores de mortalidade em uma população unicêntrica de pacientes submetidos à craniectomia descompressiva para tratamento de acidente vascular isquêmico maligno. Métodos Um estudo retrospectivo unicêntrico foi realizado com 87 pacientes com AVCI maligno submetidos à craniectomia descompressiva de emergência de janeiro de 2014 a dezembro de 2017. Idade, gênero, lateralidade, afasia, intervalo de tempo entre o início da doença e o tratamento, e escala de coma de Glasgow foram avaliados. Os pacientes foram estratificados por idade: um grupo com participantes com 60 anos de idade ou menos, e outro com participantes com mais de 60 anos para avaliação de sobrevida e mortalidade pelo teste de Kaplan-Meier e comparação log-rank. A intensidade da associação entre variáveis demográficas e clínicas foi avaliada por regressão multivariada de Cox. Resultados Houve prevalência de hipertensos (63,29%). Setenta e sete (84%) dos pacientes tiveram algum tipo de complicação pós-operatória, com predomínio de pneumonia (42,8%). O risco de morte foi 2,71 e 1,93 maior em pacientes com mais de 60 anos e com menos de 8 pontos na escala de coma de Glasgow, respectivamente. Conclusão O AVCI maligno ainda tem uma taxa de mortalidade significativa. Idade acima de 60 anos e valores da escala de coma de Glasgow abaixo de 8 foram estatisticamente correlacionados com um prognóstico desfavorável.
