ABSTRACT

La terapia endovascular (TEV) es el tratamiento estándar del ataque cerebrovascular isquémico (ACVi) con oclusión de gran vaso (OGVC). Aún no se conoce si esos resultados pueden generalizarse a la práctica diaria. Se describen los resultados de la TEV en pacientes con ACVi por OGVC dentro de las 24 horas, en un análisis retrospectivo entre enero 2013 y diciembre 2017 que incluyó 139 casos consecutivos con ACVi y OGVC en arteria cerebral media (ACM), hasta 24 horas del inicio de los síntomas, que recibieron TEV en nuestra institución. El resultado primario medido fue la escala de Rankin modificada (mRS) ≤ 2 a 90 días. Se evaluaron también: reperfusión exitosa, según la escala modificada de trombólisis en infarto cerebral (mTICI) 2b/3, hemorragia intracraneal sintomática (HIS) y mortalidad a 90 días. La edad media: 67.5 ± 15.0, siendo el 51.8% mujeres. La mediana basal de National Institute of Health Stroke Scale (NIHSS) fue 14 (IIC 8-18); la mediana del tiempo desde inicio de síntomas hasta punción inguinal: 331 min (IIC 212-503). El 45.3%, 63 pacientes, fueron tratados > 6 horas después del inicio de síntomas. La tasa de mRS ≤ 2 fue 47.5%. Se logró una reperfusión exitosa en el 74.8%. La tasa de mortalidad a 90 días fue del 18.7% y la HIS del 7.9%. Nuestro registro de pacientes de la vida real con ACVi por OGVC tratados con TEV dentro de las 24 horas mostró altas tasas de reperfusión, buenos resultados funcionales y pocas complicaciones, acorde con las recomendaciones internacionales.


Endovascular treatment (EVT) has become the standard of care for acute ischemic stroke (AIS) with proximal large vessel occlusions (LVO). However, it is still unknown whether these results can be generalized to clinical practice. We aimed to perform a retrospective review of patients who received EVT up to 24 hours, and to assess safety and efficacy in everyday clinical practice. We performed a retrospective analysis, from January 2013 to December 2017, on 139 consecutive patients with AIS for anterior circulation LVO strokes up to 24 h from symptoms onset, who received EVT in our institution. The primary outcome measured was a modified Rankin scale (mRS) ≤ 2 at 90 days. Secondary outcomes included successful reperfusion, defined as a modified Thrombolysis in Cerebral Infarction (mTICI) scale 2b/3, mortality rate at 90 days and symptomatic intracranial hemorrhage (sICH). The mean age was 67.5 ± 15.0, with 51.8% female patients. Median baseline National Institute of Health Stroke Scale (NIHSS) was 14 (IQR 8-18); median time from symptom onset to groin puncture was 331 min (IQR 212-503). Sixty-three patients (45.3%) were treated beyond 6 hours after symptoms onset. The rate of mRS ≤ 2 was 47.5%. Successful reperfusion was achieved in 74.8 %. Mortality rate at 90 days was 18.7 % and sICH was 7.9 %. Our registry of real-life patients with AIS due to LVO who received EVT within 24 hours showed high reperfusion rates, and good functional results with few complications, according to international recommendations.

ABSTRACT

ABSTRACT Background: Malignant infarction of the middle cerebral artery (MCA) occurs in a subgroup of patients with ischemic stroke and early decompressive craniectomy (DC) is one of its treatments. Objective: To investigate the functional outcome of patients with malignant ischemic stroke treated with decompressive craniectomy at a neurological emergency center in Northeastern Brazil. Methods: Prospective cohort study, in which 25 patients were divided into two groups: those undergoing surgical treatment with DC and those who continued to receive standard conservative treatment (CT). Functionality was assessed using the modified Rankin Scale (mRS), at follow-up after six months. Results: A favorable outcome (mRS≤3) was observed in 37.5% of the DC patients and 29.4% of CT patients (p=0.42). Fewer patients who underwent surgical treatment died (25%), compared to those treated conservatively (52.8%); however, with no statistical significance. Nonetheless, the proportion of patients with moderate to severe disability (mRS 4‒5) was higher in the surgical group (37.5%) than in the non-surgical group (17.7%). Conclusion: In absolute values, superiority in the effectiveness of DC over CT was perceived, showing that the reduction in mortality was at the expense of increased disability.


RESUMO Introdução: O infarto maligno da artéria cerebral média (ACM) ocorre em um subgrupo de pacientes com acidente vascular cerebral (AVC) isquêmico e a craniectomia descompressiva (CD) precoce é um de seus tratamentos. Objetivo: Investigar o desfecho funcional de pacientes com acidente vascular cerebral isquêmico maligno submetidos à craniectomia descompressiva em um centro de emergência neurológica do nordeste do Brasil. Métodos: Nesta coorte prospectiva, os pacientes foram divididos em dois grupos: aqueles submetidos a tratamento cirúrgico com craniectomia descompressiva (CD) e aqueles que mantiveram tratamento conservador (TC) padrão. A funcionalidade foi avaliada por meio da Escala de Rankin modificada (ERm) ao final de seis meses de seguimento. Resultados: Evidenciou-se desfecho favorável (ERm≤3) em 37,5% dos pacientes craniectomizados e em 29,4% dos pacientes não craniectomizados (p=0,42). A mortalidade foi menor no grupo de pacientes que se submeteram a tratamento cirúrgico (25%) do que entre aqueles tratados conservadoramente (52,8%), porém sem significância estatística. Por outro lado, a proporção de pacientes com incapacidade moderada a grave (ERm 4‒5) foi maior no grupo cirúrgico (37,5%) do que no grupo não cirúrgico (17,7%). Conclusão: Em valores absolutos, percebeu-se superioridade na eficácia do tratamento cirúrgico sobre o conservador, mostrando que a redução de mortalidade se dá à custa de aumento da incapacidade funcional.

ABSTRACT

ABSTRACT Decompressive craniectomy (DC) reduces mortality and improves outcome in patients with massive brain infarctions. The role of intracranial pressure (ICP) monitoring following DC for stroke has not been well established. Methods: We evaluated 14 patients admitted to a tertiary hospital with malignant middle cerebral artery infarctions, from October 2010 to February 2015, who underwent DC and had ICP monitoring. Patients with and without episodes of ICP elevation were compared. Results: Fourteen patients were submitted to DC and had ICP monitoring following the procedure during the period. Ten patients (71.4%) had at least one episode of sustained elevated ICP in the first seven days after surgery. Maximal ICP levels had no correlation with age, time to hemicraniectomy or Glasgow Coma Scores at admission, but had a trend toward correlation with the National Institutes of Health Stroke Scale score at admission (p = 0.1). Ventriculitis occurred in 21.4% of the patients. Conclusions: High ICP episodes and ventriculitis were common in patients following hemicraniectomy for malignant middle cerebral artery strokes. Therefore, the implications of ICP and benefits of the procedure should be firmly established.


RESUMO Craniectomia descompressiva (CD) reduz a mortalidade e melhora o desfecho em pacientes com infartos malignos de artéria cerebral média (ACM). O papel da monitorização da pressão intracraniana (PIC) após CD para infartos malignos de ACM não está bem estabelecido. Métodos: Avaliamos pacientes consecutivos internados em um hospital terciário com infartos malignos de ACM de outubro/2010 a fevereiro/2015 tratados com CD e submetidos à monitorização da PIC. Foram comparados pacientes com e sem episódios de elevação de PIC. Resultados: Quatorze pacientes (idade média 49,0 ± 12,4 anos, 42,9% do sexo masculino) foram avaliados. Dez pacientes (71,4%) tiveram pelo menos um episódio de elevação da PIC nos primeiros sete dias após a cirurgia. A PIC máxima média foi de 26,71 ± 11,64 mmHg. Os níveis máximos de PIC não apresentaram correlação com a idade, o tempo de hemicraniectomia ou com a pontuação na Escala de Coma de Glasgow na admissão, mas houve tendência a ser correlacionada com a pontuação da National Institutes of Health Stroke Scale na admissão (p = 0,1). Ventriculite ocorreu em 21,4% dos pacientes. Conclusões: Os episódios de aumento da PIC foram comuns em pacientes tratados com CD por infarto maligno de MCA e ventriculite foi evento adverso frequente nesses pacientes. Portanto, as implicações da monitorização da PIC sobre o resultado funcional, bem como os riscos e benefícios do procedimento, devem ser melhor estabelecidos.

ABSTRACT

ABSTRACT Objective To assess, by Rankin scale, the functional disability of patients who had a malignant middle cerebral artery (MCA) ischemic stroke, who underwent decompressive craniotomy (DC) within the first 30 days. Methods A cross-sectional study in a University hospital. Between June 2007 and December 2014, we retrospectively analyzed the records of all patients submitted to DC due to a malignant MCA infarction. The mortality rate was defined during the hospitalization period. The modified outcome Rankin score (mRS) was measured 30 days after the procedure, for stratification of the quality of life. Results The DC mortality rate was 30% (95% CI 14.5 to 51.9) for the 20 patients reported. The mRS 30 days postoperatively was ≥ 4 [3.3 to 6] for all patients thereafter. Conclusion DC is to be considered a real alternative for the treatment of patients with a malignant ischemic MCA infarction.

ABSTRACT

PURPOSE: Stem cell transplantation has been extensively studied as individual therapies for ischemic stroke. The present investigation is an initial effort to combine these methods to achieve increased therapeutic effects after brain ischemia. Cell transplantation may recover massive neuronal loss by replacing damaged brain cells. METHODS: Undifferentiated mouse embryonic stem (mES) cells were used to induce differentiation in vitro into neuron-like cells with good cell viability for use a graft. In this study, middle cerebral artery occlusion (MCAO) was induced in rats using intra-luminal vascular occlusion, and infused mES cells after MCAO. The animals were examined behaviorally using motor and sensory test with neurological assessment. RESULTS: Motor function of the recipients was gradually improved, whereas little improvement was observed in control rats. This result may suggest that the grafted cells have synaptic connection in the recipient brain. Our study revealed that stem cell transplantation can have a positive effect on behavioral recovery and reduction of infarct size in focal ischemic rats. Consequently after euthanasia, rats were histochemically investigated to explore graft survival with green fluorescent protein (GFP). CONCLUSION: The mouse embryonic stem cells may have advantage for use as a donor source in various neurological disorders including motor dysfunction.


OBJETIVO: O transplante de células-tronco tem sido extensivamente estudado como terapias individuais para o AVC isquêmico. A presente investigação é um esforço inicial para combinar estes métodos para alcançar aumento de efeitos terapêuticos após a isquemia cerebral. O transplante de células pode recuperar a perda neuronal intensa, substituindo as células do cérebro danificado. MÉTODOS: Células tronco embrionárias indiferenciadas de camundongo foram utilizadas para induzir in vitro a diferenciação de células como neurônio com boa viabilidade para utilizar como enxerto. Neste estudo foi induzida a oclusão da artéria cerebral média em camundongos, usando a oclusão vascular intraluminal e células embrionárias infundidas. Os animais foram examinados comportamentalmente utilizando motor e teste sensorial com avaliação neurológica. RESULTADOS: A função motora dos receptores melhorou gradualmente, ao passo que pouca melhora foi observada nos animais controle. Este resultado pode sugerir que as células enxertadas têm conexão sináptica no cérebro receptor. Nosso estudo revelou que o transplante de células-tronco pode ter um efeito positivo na recuperação do comportamento e na redução do tamanho do infarto na isquêmica focal em camundongos. Após a eutanásia foi realizada análise histoquímica para avaliar a sobrevida do enxerto com proteína fluorescente verde (GFP). CONCLUSÃO: As células embrionárias de camundongo podem ser utilizadas como enxerto em várias desordens neurológicas, incluindo disfunção motora.

ABSTRACT

A number of patients with ischemic cerebrovascular stroke suffer a progressive deterioration secondary to massive cerebral ischemia, oedema, and increased intracranial pressure [ICP]. The evolution is often fatal. Stroke is the second leading cause of death worldwide. Life-threatening, complete middle cerebral artery [MCA] infarction occurs in up to 10% of all stroke patients, and this may be characterized as massive hemispheric or malignant space-occupying supratentorial infracts[35-50] Malignant, space-occupying supratentorial ischemic stroke is characterized by mortality up to 80%, several reports indicated a beneficial effect of hemicraniectomy in this situation, converting the closed, rigid cranial vault into a semi open. The main cause of death encountered in these patients is severe postischemic brain oedema leading to raised ICP, clinical deterioration, coma, and death [20-44]. The result is dramatic decrease in ICP and a reversal of the clinical and radiological signs of hemiation. For these reasons, decompressive craniectomy has been increasingly proposed as a life-saving measure in patients with large, space-occupying hemispheric infarction. Recent successes with intra-venous [52] and intra-arterial[11] thrombolytic therapy have resulted in an increased awareness of stroke as a medical emergency[52] Thus, increasing numbers of patients are being evaluated in the early hours following the ictal event. In the process of gaining more experience in the early management of patients with acute ischemic stroke, it has become clear that in a number of these patients a progressive and often fetal deterioration secondary to mass effect from the oedematous, infarcted tissue occurs. An increasing body of experimental and clinical evidence suggests that some of these patients may benefit from undergoing a decompressive craniectomy but the timing and indications for this potential lifesaving procedure are still debated. Early hemicraniectomy based on radiographic and clinical criteria, but before signs of brainstem hemiation, has been proposed as a means of improving outcomes. The objectives of the review are to help better define the selection criteria for performing the surgery in case of supratentorial infarctions, to asses the immediate outcome in terms of time conscious recovery and survival and to assess long term outcome using standard and functional assessment scales

ABSTRACT

Contexto: O manuseio dos pacientes com infarto cerebral isquêmico inclui várias abordagens de tratamento. O tratamento cirúrgico é raramente necessário, entretanto os médicos gerais, neurologistas e neurocirurgiões devem estar atentos para essa possibilidade. Objetivo: Esta revisão visa sistematizar o tratamento cirúrgico com base em evidências nos acidentes vasculares isquêmicos. Conclusões: Apesar da crescente pesquisa envolvendo os acidentes vasculares, a taxa de mortalidade após a tentativa de tratamento cirúrgico pouco se tem alterado nas últimas décadas. Questões como quando ou a quem indicar uma craniectomia descompressiva no infarto isquêmico hemisférico são motivos de controvérsias no âmbito neurocirúrgico, e os dados da literatura são pouco esclarecedores.

ABSTRACT

Decompressive craniectomy (DC) has demonstrated efficacy in reducing mortality in hemispheric infarction of the middle cerebral artery. The aim of our study was to compare the outcome of patients submitted to DC to patients treated in a conservative way. Eighteen patients were submitted to DC and 14 received conservative treatment. Neurological status was assessed by the Glasgow Coma Score and National Institutes of Health Stroke Scale score. Mortality, modified Rankin Scale and Barthel Index scores were assessed at 90 days to evaluate outcome. We did not observe reduction in overall mortality and functional outcome in patients submitted to DC. The differences between our group and previously published series are probably related to the neurological status of the patients at the time of therapeutic decision.


Craniectomia descompressiva (CD) tem demonstrado eficácia em reduzir a mortalidade em pacientes com infarto hemisférico (IH) da artéria cerebral média. Este estudo avaliou o prognóstico dos pacientes submetidos a CD comparando a pacientes com IH tratados de maneira conservadora. Dezoito pacientes foram submetidos a CD e 14 receberam tratamento conservador. Escala de Coma de Glasgow e Escala de AVC do National Institutes of Health foram utilizadas para graduar o déficit neurológico. A mortalidade, bem como os escores obtidos na escala modificada de Rankin e índice de Barthel foram avaliados em 90 dias. Não foi observada redução de mortalidade nos pacientes submetidos a CD. Essa diferença entre os nossos resultados e os estudos publicados previamente se deve, provavelmente, à decisão cirúrgica tardia em pacientes com sinais clínicos de herniação cerebral.

ABSTRACT

O infarto maligno da artéria cerebral média é definido como a ocorrência de edema cerebral intenso, circunjacente à área de um infarto extenso.O edema pode causar deterioração da consciência, aumentar a pressão intracraniana,provocar desvio das estruturas da linha média e, finalmente,herniação cerebral e morte.Indivíduos que desenvolvem acidente vascular cerebral isquêmico maligno representam de 1 por cento a 10 por cento dos casos de isquemia cerebral supratentorial. A história natural dessa doença segue um curso previsível na maior parte dos casos,chegando a apresentar uma mortalidade de até 80 por cento quando tratados clinicamente. Os sobreviventes são incapacitados e afligidos por graves seqüelas neurológicas,tornando-se dependentes de cuidados e acamados.A craniectomia descompressiva tem evidenciado resultados animadores, com redução na mortalidade para níveis que variam de 16 por cento a 42 por cento e uma melhor qualidade de vida aos sobreviventes.A presente revisão da literatura tem como principal objetivo caracterizar, de forma prática, o acidente vascular cerebral maligno - epidemiologia,etiologia,apresentação clínica,história natural da doença,medidas terapêuticase prognóstico- bem como buscar embasamento científico à indicação de hemicraniectomia descompressiva.

ABSTRACT

OBJECTIVE: To study the neurobehavioral, biochemical and histopathological consequences of permanent focal brain ischemia, and the putative neuroprotective action of ketoprofen. METHOD: One-hundred-and-three Wistar rats divided into groups A and B were respectively submitted to 48 hours and 15 days of ischemia. Each group was divided into 4 subgroups: ischemic not treated, ischemic treated, sham not treated, and sham treated. Ischemic animals had the left middle cerebral artery coagulated. Ketoprofen was administered to treated subgroups 15 minutes before arterial coagulation (manipulation in the sham group). RESULTS: Exploratory activity and defecation were reduced in all ischemic animals in the first postoperative days and constant histopathological changes were observed in each group. The total brain glutamate levels were higher in treated animals 48 hours after surgery. CONCLUSION: No clear parallelism among behavioral, biochemical and histopathological findings was observed. Ketoprofen demonstrated no neuroprotective effect on the behavioral or histopathological aspects of focal permanent brain ischemia.


OBJETIVO: Estudar as conseqüências comportamentais, bioquímicas e histopatológicas da isquemia cerebral focal permanente e o possível efeito neuroprotetor do cetoprofeno. MÉTODO: Foram utilizados 103 ratos Wistar, divididos em grupos A e B, submetidos, respectivamente, a 48 horas e a 15 dias de isquemia. Cada grupo foi dividido em 4 subgrupos: isquêmico não tratado; isquêmico tratado; sham não tratado; sham tratado. Nos animais isquêmicos foi coagulada a artéria cerebral média esquerda. Os subgrupos tratados receberam cetoprofeno 15 minutos antes da oclusão ou manipulação arterial. RESULTADOS: Os animais isquêmicos reduziram a atividade exploratória e as evacuações nos primeiros dias pós-operatórios e mostraram alterações histopatológicas constantes em cada grupo. As concentrações do glutamato total 48 horas após a cirurgia foram maiores nos animais tratados. CONCLUSÃO: Não houve um paralelismo entre os achados comportamentais, bioquímicos e histopatológicos. O cetoprofeno não apresentou efeito protetor contra isquemia cerebral focal permanente, nos aspectos comportamentais e histopatológicos.

ABSTRACT

Malignant middle cerebral territory infarction represents 5 to 10 percent of all brain infarctions. Its mortality is 80 percent, due to brain herniation and it is not reduced by medical treatment. Decompressive hemicraniectomy reduces mortality to 12 percent, and the subsequent quality of life of patients is acceptable. We report two male patients aged 61 and 54 years, with a malignant middle cerebral territory infarction who were treated with decompressive hemicraniectomy. After two years of follow up, both patients are self-sufficient and live at home with their families.
