Hemorragia intraventricular y factores asociados en recién nacidos pretérmino: Cohorte retrospectiva / Intraventricular hemorrhage and factors associated in preterm newborns

RESUMEN Objetivo: Estimar la frecuencia de la hemorragia intraventricular y los factores asociados en neonatos pretérmino hospitalizados en una unidad de cuidado intensivo neonatal de alta complejidad. Metodología: Estudio de cohorte, en el que se incluyeron neonatos menores de 37 semanas de gestación, atendidos en una institución de alta complejidad, entre enero de 2015 hasta diciembre de 2018; se valoró el desarrollo de hemorragia intraventricular diagnosticada por métodos de imagen. Los datos se obtuvieron a partir de la revisión de las historias clínicas electrónicas y se analizaron variables sociodemográficas y clínicas. Resultados: Se incluyeron 296 pacientes, 128 (43,2%) eran mujeres; 23 pacientes (7,8%) desarrollaron hemorragia intraventricular, la cual predominó en el sexo femenino (11,7%). La mediana de edad gestacional fue de 34 semanas. Los factores asociados al desarrollo de hemorragia intraventricular fueron el peso al nacer por debajo de 1500 gr, las infecciones (p<0,0001), los cuadros de apneas (<0,0001), la hiperglicemia (p = 0,025) y la necesidad de surfactante (p= 0,019); por su parte, los esteroides prenatales se comportaron como un factor protector (p=0,002). Los pacientes con hemorragia intraventricular tuvieron mayor necesidad de ventilación mecánica, mayor uso de inotrópicos o vasopresores, más transfusiones y mayor estancia hospitalaria. Conclusiones: A pesar de que la hemorragia intraventricular resultó ser una patología poco frecuente en la población de neonatos analizada, existen factores de riesgo que se relacionan con su desarrollo, como la edad gestacional, el bajo peso al nacer, las infecciones, las apneas y la hiperglicemia.

ABSTRACT Objective: Estimate the frequency of intraventricular hemorrhage and associated factors in hospitalized preterm infants in a highly complex neonatal intensive care unit. Methodology: Cohort study, which included neonates younger than 37 weeks gestation, attended in a highly complex institution, between January 2015 and December 2018; The development of intraventricular hemorrhage diagnosed by imaging methods was assessed. The data was obtained from the review of the electronic medical records and sociodemographic and clinical variables were analyzed. Results: 296 patients were included, 128 (43.2%) were women; 23 patients (7.8%) developed intraventricular hemorrhage, which predominated in the female sex (11.7%). The median gestational age was 34 weeks. The factors associated with the development of intraventricular hemorrhage were birth weight below 1500 gr, infections (p <0.0001), apnea symptoms (<0.0001), hyperglycemia (p = 0.025) and surfactant requirement (p = 0.019); meanwhile, prenatal steroids behaved as a protective factor (p = 0.002). Patients with intra-ventricular hemorrhage had a greater need for mechanical ventilation, use of inotropics or vasopressors, more transfusions, and a longer hospital stay. Conclusions: Despite the fact that intraventricular hemorrhage turned out to be a rare pathology in the analyzed neonatal population, there are risk factors related to its development, such as gestational age, low birth weight, infections, apneas, and hyperglycemia.

Síntomas neurológicos focales transitorios por microsangrados cerebrales en hipofibrinogenemia congénita: reporte de un caso / Cerebral microbleeds' transient focal neurological symptoms in congenital hypofibrinogenemia: a case report

Resumen Introducción: Un espectro de enfermedad hemorrágica intracraneal se puede presentar con síntomas neurológicos focales transitorios; aunque las enfermedades congénitas del fibrinógeno son inusuales y rara vez se manifiestan de esta manera, a continuación se presenta un caso de microsangrados cerebrales por hipofibrinogenemia congénita con síntomas neurológicos focales transitorios. Presentación del caso: Paciente masculino de 29 años de edad con microsangrados cerebrales por hipofibrinogenemia congénita con síntomas neurológicos focales transitorios. Discusión: La hemorragia intracerebral de vasos pequeños es una causa de síntomas neurológicos focales transitorios. La prevalencia de microhemorragias cerebrales en la población adulta mayor es un problema altamente reconocido, sin embargo, la incidencia de estos microsangrados en personas más jóvenes es baja y desconocida. Las discrasias sanguíneas, como el trastorno hereditario del fibrinógeno, son una causa de anomalías hereditarias de la coagulación sanguínea, donde este tiene una función importante en el control del sangrado por agregación plaquetaria y en la cascada de coagulación. La ausencia de fibrinógeno normal conduce a una altercación en la hemostasia y, por tanto, a complicaciones hemorrágicas. Conclusiones: Los síntomas neurológicos focales transitorios pueden ser causados por una enfermedad vascular cerebral hemorrágica de vasos pequeños, donde las discrasias sanguíneas congénitas son una causa rara de este tipo de enfermedad cerebrovascular.

Abstract Introduction: Intracranial hemorrhagic disease can present with transient focal neurological symptoms. Congenital fibrinogen diseases are unusual and can rarely manifest in this way. Below we present a case of cerebral microbleeds due to congenital hypofibrinogenemia with transient focal neurological symptoms. Case presentation: This is a 29-year-old man with cerebral microbleeds due to congenital hypofibrino-genemia with transient focal neurological symptoms. Discussion: Cerebral microbleed and intracerebral hemorrhage is a cause of transient focal neurological symptoms. The prevalence of cerebral microbleeds in the elderly population is a highly recognized problem. However, the incidence of these microbleeds in younger people is low and unknown. Blood dyscrasias, such as inherited fibrinogen disorder, are a cause of inherited abnormalities of blood clotting. Fibrinogen has an important role in the control of bleeding due to platelet aggregation and is part of the coagulation cascade. The absence of normal fibrinogen induces alteration in platelet and coagolation hemostasis and, therefore, causes hemorrhagic complications. Conclusions: Transient focal neurological symptoms may be caused by small vessel hemorrhagic cere-brovascular disease. Congenital blood dyscrasias are a rare cause of this type of cerebrovascular disease.

Early-onset neonatal sepsis as a risk factor for peri-intraventricular hemorrhage in premature infants / Sepse precoce como fator de risco para hemorragia peri-intraventricular em prematuros

ABSTRACT Objective: To assess early-onset sepsis as a risk factor of peri-intraventricular hemorrhage in premature infants born at less than or equal to 34 weeks' gestation and admitted to a neonatal intensive care unit (NICU). Methods: This retrospective cohort study included premature patients born at less than or equal to 34 weeks' gestation who were admitted to the NICU of a tertiary hospital in southern Brazil, and born from January 2017 to July 2021. Data were collected from patients' medical records. Early-onset sepsis was measured according to the presence or absence of diagnosis within the first 72 hours of life, whereas the outcome, peri-intraventricular hemorrhage, was described as the presence or absence of hemorrhage, regardless of its grade. Results: Hazard ratios were calculated using Cox regression models. A total of 487 patients were included in the study, of which 169 (34.7%) had some degree of peri-intraventricular hemorrhage. Early-onset sepsis was present in 41.6% of the cases of peri-intraventricular hemorrhage, which revealed a significant association between these variables, with increased risk of the outcome in the presence of sepsis. In the final multivariate model, the hazard ratio for early-onset sepsis was 1.52 (95% confidence interval 1.01-2.27). Conclusion: Early-onset sepsis and the use of surfactants showed to increase the occurrence of the outcome in premature children born at less than or equal to 34 weeks' gestation. Meanwhile, factors such as antenatal corticosteroids and gestational age closer to 34 weeks' gestations were found to reduce the risk of peri-intraventricular hemorrhage.

RESUMO Objetivo: O objetivo do presente trabalho foi avaliar a sepse precoce como fator de risco para hemorragia peri-intraventricular (HPIV) em prematuros com 34 semanas ou menos, admitidos em Unidade de Terapia Intensiva (UTI) Neonatal. Métodos: Este estudo de coorte retrospectivo incluiu pacientes prematuros com 34 semanas ou menos, que receberam alta da UTI Neonatal de hospital terciário, no sul do Brasil, nascidos no período de janeiro de 2017 a julho de 2021. Os dados foram coletados por meio dos prontuários desses pacientes. A sepse precoce foi mensurada conforme a presença ou a ausência do diagnóstico nas primeiras 72 horas de vida. Já o desfecho, hemorragia peri-intraventricular, foi descrito conforme a presença ou ausência da hemorragia, independentemente do grau. Resultados: Hazard ratios (HR) foram calculados por meio de modelos de regressão de Cox. Foram incluídos no estudo 487 pacientes. Destes, 169 (34,7%) apresentaram algum grau de hemorragia peri-intraventricular. A sepse precoce esteve presente em 41,6% dos casos de hemorragia peri-intraventricular e apresentou associação significativa, elevando o risco do desfecho quando presente. No modelo multivariável final, o HR para a sepse precoce foi de 1,52 (intervalo de confiança de 95% — IC95% 1,01-2,27). Conclusão: Sepse precoce e uso de surfactante demonstraram aumentar a ocorrência do desfecho em crianças prematuras até 34 semanas, enquanto fatores como corticoide antenatal e idades gestacionais mais próximas a 34 semanas mostraram reduzir o risco de ocorrência hemorragia peri-intraventricular.

The clinical effect of minimally invasive stereotactic puncture intracranial hematoma removal in the treatment of patients with cerebral hemorrhage: a meta-analysis.

OBJECTIVE: The objective of the study was to systemically evaluate the clinical efficacy of minimally invasive stereotactic puncture for intracranial hematoma evacuation in patients with cerebral hemorrhage. MATERIALS AND METHODS: Relevant studies in PubMed, Web of Science, MEDLINE, China National Knowledge Infrastructure, Wanfang, and VIP databases were searched. A meta-analysis was performed following the inclusion and exclusion criteria screening, data extraction, and literature quality evaluation. RESULTS: Fifteen studies involving 1312 patients were included with 673 participants in the experimental group and 639 in the control group. The results of the meta-analysis showed that, compared with traditional craniotomy or treatment, minimally invasive stereotactic puncture intracranial hematoma removal had a higher clinical total effective rate in patients with cerebral hemorrhage, an outcome that could significantly shorten the hospitalization time of patients with cerebral hemorrhage. The level of post-operative activities of daily living was significantly higher, the incidence of postoperative complications was lower, and the mortality rate was lower. However, there was no significant difference in the degree of post-operative neurological deficit. CONCLUSION: Compared with traditional craniotomy or conservative treatment, minimally invasive stereotactic puncture intracranial hematoma removal has a higher clinical efficacy in the treatment of patients with cerebral hemorrhage, which can improve the post-operative daily life and abilities of patients.

Intracranial hemorrhages in patients with COVID-19: a systematic review of the literature, regarding six cases in an Amazonian population / Hemorragias intracranianas em pacientes com COVID-19: uma revisão sistemática da literatura, a propósito de seis casos na população amazônica

Abstract Background Coronavirus disease 2019 (COVID-19) has emerged as a public health emergency worldwide, predominantly affecting the respiratory tract. However, evidence supports the involvement of extrapulmonary sites, including reports of intracranial hemorrhages. Objective To describe six original cases and review the literature on intracranial hemorrhages in patients diagnosed with COVID-19 by molecular methods. Methods A systematic literature review was performed on MEDLINE, PubMed, and NCBI electronic databases to identify eligible studies. Of the total 1,624 articles retrieved, only 53 articles met the inclusion criteria. Results The overall incidence of intracranial hemorrhage in patients hospitalized for COVID-19 was 0.26%. In this patient group, the mean age was 60 years, and the majority were male (68%) with initial respiratory symptoms (73%) and some comorbidity. Before the diagnosis of hemorrhage, 43% of patients were using anticoagulants, 47.3% at therapeutic doses. The intraparenchymal (50%) was the most affected compartment, followed by the subarachnoid (34%), intraventricular (11%), and subdural (7%). There was a predominance of lobar over non-lobar topographies. Multifocal or multicompartmental hemorrhages were described in 25% of cases. Overall mortality in the cohort studies was 44%, while around 55% of patients were discharged from hospital. Conclusion Despite the unusual association, the combination of these two diseases is associated with high rates of mortality and morbidity, as well as more severe clinicoradiological presentations. Further studies are needed to provide robust evidence on the exact pathophysiology behind the occurrence of intracranial hemorrhages after COVID-19 infection.

Resumo Antecedentes A COVID-19 emergiu como uma emergência de saúde pública em todo o mundo, proporcionando lesão principalmente do trato respiratório. No entanto, várias evidências apontam para acometimento de sítios extrapulmonares, incluindo relatos de hemorragias intracranianas. Objetivo Descrever seis casos originais e revisar a literatura sobre hemorragias intracranianas em pacientes com diagnostico de COVID-19 por métodos moleculares. Métodos A revisão sistemática da literatura foi feita nas bases de dados eletrônicas da MEDLINE, PubMed e NCBI para identificar os estudos elegíveis. Do total de 1.624 artigos recuperados, apenas 53 artigos preencheram os critérios de inclusão. Resultados A incidência geral de hemorragia intracraniana nos pacientes internados por COVID-19 foi de 0,26%. A média de idade foi de 60 anos, e a maioria dos pacientes era do sexo masculino (68%) com sintomas respiratórios iniciais (73%) e alguma comorbidade. Antes do diagnóstico de hemorragia, 43% estavam em uso de anticoagulantes, 47,3% destes em doses terapêuticas. O compartimento mais acometido foi o intraparenquimatoso (50%), seguido do subaracnoideo (34%), intraventricular (11%) e subdural (7%). Houve predomínio de topografias lobares sobre as não-lobares. Hemorragias multifocais ou multicompartimentais foram descritas em 25% dos casos. A mortalidade geral nos estudos de coorte foi de 44%, enquanto houve alta hospitalar em cerca de 55% dos pacientes. Conclusão Apesar da associação incomum, a combinação dessas doenças está relacionada com altas taxas de mortalidade e morbidade, bem como apresentações clínico-radiológicas mais graves. Mais estudos são necessários para oferecer evidências robustas sobre a fisiopatologia exata por trás da ocorrência de hemorragias intracranianas após infecção por COVID-19.

Hipernatremia en pacientes con estado crítico por afecciones neurológicas

Fundamento: los trastornos del sodio son los más comunes y menos entendidos en pacientes con lesión cerebral aguda debido al papel principal que desempeña el sistema nervioso central en la regulación de la homeostasis del sodio y agua lo que puede llevar a complicaciones graves y resultados adversos, incluyendo la muerte. Objetivo: determinar la contribución a la mortalidad de la hipernatremia en pacientes con estado crítico por afecciones neurológicas. Métodos: estudio observacional analítico sobre 55 pacientes que ingresaron en las unidades de atención al grave del Hospital Universitario Arnaldo Milián Castro, entre octubre del 2020 y mayo del 2022, con independencia del valor del sodio plasmático a su admisión en el servicio, así como durante su estadía en las unidades de atención al grave. Se emplearon métodos estadísticos univariados y bivariados en el análisis de los datos. Resultados: el promedio de edad fue de 60±16 años. Los diagnósticos más relevantes fueron la hemorragia intraparenquimatosa (56,37 %), el trauma craneoencefálico y el accidente cerebrovascular isquémico (ambos 30 %). Las concentraciones plasmáticas de sodio mostraron diferencias significativas (pX2= 0,000), siendo la media mayor a las 24 horas de ingreso (174,2±133,6) y la menor al 5to día (102,9±72,9). Existió correlación significativa entre las concentraciones plasmáticas de sodio al ingreso ( 24 h y 72 h) y el estado al egreso. En el análisis bivariado individual por período, solo a las 24 horas hubo relación significativa, en este periodo la hipernatremia contribuyó a la mortalidad en 1,78 veces más que en aquellos que no tenían el sodio elevado (OR=1,78 con IC: 1,39-3,4). Conclusiones: la hipernatremia en el paciente con estado crítico por afecciones neurológicas se asocia con incremento de la mortalidad.

Background: sodium disorders are the most common and least understood in patients with acute brain injury due to the major role played by the central nervous system in regulating sodium and water homeostasis, which can lead to serious complications and adverse outcomes, including death. Objective: to determine the hypernatremia contribution to mortality in patients with neurological conditions in critical state. Methods: longitudinal analytical observational study on 55 patients who were admitted to the acute care units at the Arnaldo Milián Castro University Hospital, between October 2020 and May 2022, regardless of the plasma sodium value upon admission to the service, as well as during their stay in the critical care units. Univariate and bivariate statistical methods were used in data analysis. Results: the average age was 60 ± 16 years. The most relevant diagnoses were intraparenchymal hemorrhage (56.37%), head trauma, and ischemic stroke (both 30%). Plasma sodium concentrations showed significant differences (pX2= 0.000), with the highest average at 24 hours of admission (174.2 ± 133.6) and the lowest at the 5th day (102.9 ± 72.9). There was a significant correlation between plasma sodium concentrations at admission, 24h and 72h with the state at discharge. In the individual bivariate analysis by period, there was only a significant relationship after 24 hours. In this period, hypernatremia contributed 1.78 times more to mortality than in those who did not have elevated sodium (OR=1.78 with CI: 1,39-3,4). Conclusions: hypernatremia in critically ill patients with neurological conditions is associated with increased mortality.

Dilated optic nerve sheath by ultrasound predicts mortality among patients with acute intracerebral hemorrhage / A bainha do nervo óptico dilatada na ultrassonografia prediz mortalidade na hemorragia intraparenquimatosa aguda

Abstract Background Intracerebral hemorrhage (ICH) is a deadly disease and increased intracranial pressure (ICP) is associated with worse outcomes in this context. Objective We evaluated whether dilated optic nerve sheath diameter (ONSD) depicted by optic nerve ultrasound (ONUS) at hospital admission has prognostic value as a predictor of mortality at 90 days. Methods Prospective multicenter study of acute supratentorial primary ICH patients consecutively recruited from two tertiary stroke centers. Optic nerve ultrasound and cranial computed tomography (CT) scans were performed at hospital admission and blindly reviewed. The primary outcome was mortality at 90-days. Multivariate logistic regression, ROC curve, and C-statistics were used to identify independent predictors of mortality. Results Between July 2014 and July 2016, 57 patients were evaluated. Among those, 13 were excluded and 44 were recruited into the trial. Their mean age was 62.3 ± 13.1 years and 12 (27.3%) were female. On univariate analysis, ICH volume on cranial CT scan, ICH ipsilateral ONSD, Glasgow coma scale, National Institute of Health Stroke Scale (NIHSS) and glucose on admission, and also diabetes mellitus and current nonsmoking were predictors of mortality. After multivariate analysis, ipsilateral ONSD (odds ratio [OR]: 6.24; 95% confidence interval [CI]: 1.18-33.01; p = 0.03) was an independent predictor of mortality, even after adjustment for other relevant prognostic factors. The best ipsilateral ONSD cutoff was 5.6mm (sensitivity 72% and specificity 83%) with an AUC of 0.71 (p = 0.02) for predicting mortality at 90 days. Conclusion Optic nerve ultrasound is a noninvasive, bedside, low-cost technique that can be used to identify increased ICP in acute supratentorial primary ICH patients. Among these patients, dilated ONSD is an independent predictor of mortality at 90 days.

Resumo Antecedentes A hemorragia intraparenquimatosa (HIP) aguda apresenta elevada morbimortalidade e a presença de hipertensão intracraniana (HIC) confere um pior prognóstico. Objetivo Avaliamos se a dilatação do diâmetro da bainha do nervo óptico (DBNO) através do ultrassom do nervo óptico (USNO) na admissão hospitalar seria preditora de mortalidade. Métodos Estudo multicêntrico e prospectivo de pacientes consecutivos com HIP supratentorial primária aguda admitidos em dois centros terciários. Ultrassom do nervo óptico e tomografia computadorizada (TC) de crânio foram realizados na admissão e revisados de forma cega. O desfecho primário do estudo foi a mortalidade em 3 meses. Análises de regressão logística, curva de característica de operação do receptor (ROC, na sigla em inglês) e estatística-C foram utilizadas para identificação dos preditores independentes de mortalidade. Resultados Entre julho de 2014 e julho de 2016, 44 pacientes foram incluídos. A idade média foi 62,3 (±13,1) anos e 12 (27,3%) eram mulheres. Na análise univariada, o volume da HIP na TC de crânio, DBNO ipsilateral à HIP, glicemia, escala de coma de Glasgow (ECG) e NIHSS na admissão hospitalar, e também diabetes mellitus e não-tabagista foram preditores de mortalidade. Após análise multivariada, o DBNO ipsilateral à HIP permaneceu como preditor independente de mortalidade (odds ratio [OR]: 6,24; intervalo de confiança [IC] de 95%: 1,18-33,01; p = 0,03). O melhor ponto de corte do DBNO ipsilateral como preditor de mortalidade em 3 meses foi 5,6mm (sensibilidade 72% e especificidade 83%) e área sob a curva (AUC, na sigla em inglês) 0,71 (p = 0,02). Conclusão O USNO é um método não-invasivo, beira-leito, de baixo custo, que pode ser empregado para estimar a presença de HIC em pacientes com HIP supratentorial primária aguda. A presença de DBNO dilatada é um preditor independente de mortalidade em 3 meses nesses pacientes.

Accidente Cerebrovascular en tallo cerebral, presentación inusual con evolución tórpida en paciente renal

La tercera causa de morbi-mortalidad en muchos países, es el accidente cerebrovascular (ACV), la incidencia es mayor en los pacientes con hemodiálisis. La presencia del ACV hemorrágico se vincula con peores resultados; el diagnóstico y tratamiento precoces son primordiales por la rápida expansión de la misma, que provoca un detrimento neurológico, hasta un desenlace fatal. Se presenta el caso de una mujer de 52 años, ingresa por servicio de emergencia en fecha 23/05/23 con antecedente de terapia de reemplazo renal tri-semanal, hipertensión arterial, diabetes mellitus; cuadro clínico con cefalea súbita, de moderada intensidad, acompañado de somnolencia, entumecimiento a nivel de columna cervicodorsal, paraparesia en extremidades inferiores e hipertensión; tomografía de cráneo con ACV hemorrágico pre tallo cerebral; ingresa a la Unidad de Terapia Intensiva (UTI) para monitorización y manejo, sin embargo a pesar del tratamiento evoluciono de manera tórpida y fallece en fecha 11/06/2023.

The third cause of morbidity and mortality in many countries is cerebrovascular accident (CVA), the incidence is higher in hemodialysis patients. The presence of hemorrhagic stroke is associated with worse results; early diagnosis and treatment are essential due to its rapid expansion, which causes neurological detriment, up to a fatal outcome. The case of a 52-year-old woman is presented, admitted for emergency service on 05/23/23 with a history of three-weekly renal replacement therapy, arterial hypertension, diabetes mellitus; clinical picture with sudden headache of moderate intensity, accompanied by drowsiness, numbness at the level of the cervicodorsal spine, paraparesis in the lower extremities and hypertension; skull tomography with pre-brain stem hemorrhagic stroke; he was admitted to the Intensive Care Unit (ICU) for monitoring and management, however despite the treatment he evolved torpidly and died on 06/11/2023.

Cerebrovascular mortality: trend and seasonality in Brazilian capitals, 2000-2019 / Mortalidade cerebrovascular: tendência e sazonalidade nas capitais brasileiras, 2000-2019

ABSTRACT OBJECTIVE To evaluate the trend and seasonality of cerebrovascular mortality rates in the adult population of Brazilian capitals from 2000 to 2019. METHODS This is an ecological and descriptive study of a time series of mortality due to cerebrovascular causes in adults (≥ 18 years) living in Brazilian capitals from 2000 to 2019, based on the Brazilian Mortality Information System. Descriptive statistical techniques were applied in the exploratory analysis of data and in the summary of specific, standardized rates and ratios by sociodemographic characteristics. The jointpoint regression model was used to estimate the trend of cerebrovascular mortality rates by gender, age groups, and geographic regions. The seasonal variability of rates by geographic regions was estimated using the generalized additive model by smoothing cubic splines. RESULTS People aged over 60 years comprised 77% of all cerebrovascular deaths. Women (52%), white individuals (47%), single people (59%), and those with low schooling (57%, elementary school) predominated in our sample. Recife (20/1,000 inhab.) and Vitória (16/1,000 inhab.) showed the highest crude mortality rates. Recife (49/10,000 inhab.) and Palmas (47/10,000 inhab.) prevailed after we applied standardized rates. Cerebrovascular mortality rates in Brazil show a favorable declining trend for adults of all genders. Seasonality influenced rate increase from July to August in almost all region capitals, except in the North, which rose in March, April, and May. CONCLUSIONS Deaths due to cerebrovascular causes prevailed in older single adults with low schooling. The trend showed a tendency to decline and winter, the greatest risk. Regional differences can support decision-makers in implementing public policies to reduce cerebrovascular mortality.

RESUMO OBJETIVO Avaliar a tendência e a sazonalidade das taxas de mortalidade cerebrovascular na população adulta das capitais brasileiras de 2000 a 2019. MÉTODOS Estudo ecológico e descritivo de séries temporais de mortalidade por causas cerebrovasculares em adultos (≥ 18 anos) residentes nas capitais do Brasil no período 2000-2019, obtidas do Sistema de Informações sobre Mortalidade. Técnicas de estatística descritiva foram aplicadas na análise exploratória dos dados e no resumo de taxas específicas, padronizadas e razões por características sociodemográficas. A regressão de pontos de junção (jointpoint regression model) estimou a tendência das taxas de mortalidade cerebrovascular por sexo, grupos etários e regiões geográficas. A variabilidade sazonal por regiões geográficas das taxas foi estimada utilizando o modelo aditivo generalizado por meio de splines de suavização cúbica. RESULTADOS As pessoas maiores de 60 anos representaram 77% dos óbitos cerebrovasculares. Predominaram o sexo feminino (52%), a raça branca (47%), os solteiros (59%) e a baixa escolaridade (57%, ensino fundamental). As capitais Recife (20/1.000 hab.) e Vitória (16/1.000 hab.) apresentaram as maiores taxas brutas de mortalidade. Aplicando as taxas padronizadas Recife (49/10.000 hab.) e Palmas (47/10.000 hab.) prevaleceram. As taxas de mortalidade cerebrovascular no Brasil apresentam uma tendência favorável ao declínio em ambos os sexos e em adultos. A sazonalidade mostrou influenciar na elevação das taxas entre os meses de julho a agosto em quase todas as capitais das regiões, exceto na Norte, que se elevaram nos meses de março, abril e maio. CONCLUSÕES Os óbitos por causa cerebrovascular prevaleceram em pessoas idosas, solteiras e com baixa escolaridade. A tendência foi favorável ao declínio, sendo o inverno o período de maior risco. As diferenças regionais permitem subsidiar os tomadores de decisões em relação à implementação de políticas públicas para reduzir a mortalidade cerebrovascular.

Cuidados de enfermería para reducir el riesgo de hemorragia en pacientes con trombolisis por ICTUS isquémico

Objetivo: Describir las intervenciones de enfermería en pacientes con trombolisis en ictus isquémico para reducir el riesgo de hemorragia. Metodología: Investigación secundaria, revisión; integrativa. Se realizó una pregunta con la estrategia PICO: ¿Cuáles son las intervenciones de enfermería en pacientes con trombolisis en ictus isquémico para reducir el riesgo de hemorragia antes, durante y después de trombolizar al paciente? Se construyó una ecuación de búsqueda utilizando booleanos, DeCS/MeSH para facilitar la búsqueda en bases de datos. Los artículos encontrados fueron leídos críticamente y clasificados por nivel de evidencia y grados de recomendación. Estudio sin riesgo ético por ser de tipo documental. Se respetaron los derechos de autor de acuerdo con la Ley 44 de 1993. Resultados: Con las 14 unidades de análisis finales fueron construidos 3 dominios que realzan la importancia de los conocimientos y el actuar del personal de enfermería en la reducción del riesgo de hemorragia en pacientes con ictus isquémico. Dichos dominios son: 1) control y monitorización de la tensión arterial; principal cuidado de enfermería antes, durante y después de la trombolisis, 2) terapia combinada; disminución de riesgos hemorrágicos - aumento de la ventana terapéutica, 3) dosificación segura de alteplasa en situaciones contraindicadas. Conclusiones: La intervención de enfermería más significativa durante esta terapia es la monitorización y control de las cifras tensionales, debido a que su aumento mayor a 185/110 mmHg es el factor de riesgo más significativo en la aparición de hemorragias.

Objective: Describe nursing interventions in patients with thrombolysis in ischemic stroke to reduce the risk of bleeding. Methodology: Secondary research, type of review; integrative. A question was asked with the PICO strategy: What are the nursing interventions in patients with thrombolysis in ischemic stroke to reduce the risk of bleeding before, during, and after thrombolyzing the patient? A search equation was constructed using Boolean, DeCS / MeSH to facilitate database searching. The articles were critically read and classified by level of evidence and degrees of recommendation. Study without ethical risk because it is documentary type, copyright was respected according to Law 44 of 1993. Results: With the 14 final analysis units, 3 domains were constructed that highlight the importance of knowledge and the actions of the nursing staff in reducing the risk of bleeding in patients with ischemic stroke. These domains are: 1) control and monitoring of blood pressure; main nursing care before, during, and after thrombolysis, 2) combined therapy; decreased bleeding risks - increased therapeutic window, 3) safe dosage of alteplase in contraindicated situations. Conclusions: The most significant nursing intervention during this therapy is the monitoring and control of blood pressure figures, since and increase larger than 185/110 mmHg is the most significant risk factor in the appearance of bleeding.

Anticoagulation and Stroke / Anticoagulação e AVC

Abstract In 2019, the American Heart Association did not recommend the emergent use of anticoagulation to prevent recurrence or progression of acute ischemic stroke. However, its indication in patients with extracranial artery intraluminal thrombus with artery-to-artery cerebral embolization must be analyzed. In this article, we will also discuss other indications of anticoagulation. This treatment could be indicated in patients with ischemic stroke caused by embolization from cervical artery dissection, catastrophic antiphospholipid antibodies syndrome (APS) and some cases of Covid 19. For secondary prevention, anticoagulation is recommended for Cardioembolic stroke such as nonvalvular atrial fibrillation and other cardiopathies, some patients with cervical artery dissection, stroke associated with cancer, and thrombophilia such as APS. The timing to restart anticoagulation after a large ischemic stroke or after a cerebral hemorrhagic transformation always represent a challenge. Even in patients with high risk of thromboembolism it should be delayed at least two weeks, ideal after four weeks.

Resumo Anticoagulação na fase aguda do acidente vascular isquêmico (AVCI) ainda é um tema bastante controverso. Em 2019, a American Heart Association (AHA) não recomendou o uso precoce da anticoagulação para evitar a progressão ou recorrência de AVCIs de grandes artérias. Mas sugere que a anticoagulação em pacientes com AVCI por embolização a partir de trombos intraluminais aderidos a parede de vasos extracranianos fosse analisada. Tanto a antiagregação como anticoagulação são opções terapêuticas nos casos de AVCI por dissecção arterial cervical. Mas em pacientes com AVCI por mecanismo de embolização, a anticoagulação poderia ser indicada. Pacientes com AVCI e sindrome catastrófica por anticorpos antifosfolípides devem ser anticoagulados além de receber tratamento específico. Outra indicação seriam casos de trombofilia como Covid 19. Nesse artigo de revisão será discutida a prevenção secundária de AVCI em situações específicas (AVCI cardioembólico em pacientes com fibrilação atrial não valvular ou outras cardiopatias, AVCI em casos oncológicos, além de outras trombofilias), além do período ideal para se introduzir ou reiniciar a anticoagulação após transformação hemorrágica.

Predictores de mortalidad intrahospitalaria y de mal pronóstico funcional en pacientes sometidos a evacuación quirúrgica de hemorragia intracerebral / Predictors of in-hospital mortality and poor functional outcomes in patients who underwent surgical evacuation of intracerebral hemorrhage

RESUMEN Objetivo : Determinar predictores de mortalidad intrahospitalaria y mal pronóstico funcional en pacientes sometidos a cirugía por hemorragia intracerebral. Materiales y métodos : Se analizaron las historias clínicas, reportes operatorios y tomografías cerebrales de pacientes con hemorragia intracerebral desde marzo 2018 hasta marzo de 2020. Se realizó un análisis de regresión logística univariado y multivariado para determinar predictores independientes de mortalidad intrahospitalaria y mal pronóstico funcional al alta. Resultados : La mortalidad intrahospitalaria fue de 33,7 % (n = 31 pacientes). Predictores independientes de mortalidad fueron el sexo femenino (OR = 3.01; p = 0.031) y un Glasgow < 8 puntos al ingreso (OR = 3.19; p = 0.031). Un mal pronóstico funcional luego de la intervención se encontró en 77 pacientes (83,7 %). Predictores independientes de mal pronóstico funcional fueron una Escala de Rankin modificada > 3 (OR = 15.5; p = 0.01) y déficit motor pre-operatorio (OR = 8.95; p = 0.042). Conclusiones : En pacientes con diagnóstico de hemorragia intracerebral tratados con cirugía se encontró una alta mortalidad y morbilidad. El sexo femenino y factores clínicos como el estado de conciencia y el estado funcional al ingreso fueron predictores independientes de mortalidad intrahospitalaria y mal pronóstico funcional.

ABSTRACT Objective : To determine predictors of in-hospital mortality and poor functional prognosis in patients undergoing surgery for intracerebral hemorrhage. Materials and Methods : Clinical records, operative reports, and cerebral CT scans of patients with intracerebral hemorrhage from March 2018 to March 2020 were analyzed. Univariate and multivariate logistic regression analyses were performed for determining independent predictors of in-hospital mortality and poor functional prognosis at discharge. Results : In-hospital mortality was 33.7% (n= 31 patients). Independent predictors for mortality were female sex (OR= 3.01, p= 0.031) and Glasgow score <8 on admission (OR= 3.19, p= 0.031). A poor functional prognosis after the intervention was found in 77 patients (83.7%). Independent risk factors for a poor functional prognosis were score >3 in the modified Rankin scale (OR= 15.5; p= 0.01), and preoperative motor deficit (OR= 8.95; p= 0.042). Conclusions : In patients with intracerebral hemorrhage who were surgically treated, high morbidity and mortality rates were found. Female sex and clinical factors, such as consciousness condition and functional status on admission were independent predictors for in-hospital mortality and poor functional prognosis.

Neuroimagen en pacientes con infección por COVID-19 descripción de hallazgos y revisión de la literatura / Neuroimaging in patients with COVID-19: findings description and review of the literature

El síndrome respiratorio agudo severo causado por coronavirus 2 (SARS-CoV-2) es responsable de la propagación mundial de la enfermedad por coronavirus (COVID-19). Nuestro conocimiento hasta el momento del impacto de este virus en el sistema nervioso es limitado. El propósito de este artículo es revisar el espectro de los diversos hallazgos en neuroimágenes asi como la fisiopatología en los pacientes con COVID-19. Se necesitan estudios futuros que examinen el impacto de los síntomas y su correlación con las neuroimágenes durante el curso de la enfermedad, para aclarar y evaluar aún más el vínculo entre las complicaciones neurológicas y el resultado clínico, así como limitar las consecuencias a largo plazo.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the global spread of coronavirus disease (COVID-19). Our understanding, so far, of the impact this virus has on the nervous system is limited. Our article aims to review the spectrum of neuroimaging findings in patients with COVID 19, as well as, their underlying pathophysiology. Future studies examining the impact of symptoms and their correlation with neuroimaging findings duirng the course of the disease are needed to further clarify and evaluate the association between neurological complications and clinical outcome, as well as to limit long-term consequences.

Moyamoya disease in Mexico: our experience.

INTRODUCTION: Moyamoya disease (MD) is a progressive, occlusive disease of the arteries of the anterior cerebral circulation that may cause ischaemia or haemorrhage. Patient management aims to prevent new cerebrovascular events through surgical revascularisation and/or pharmacological treatment. MATERIALS AND METHODS: We studied a series of 17 patients with MD (n = 14) or moyamoya syndrome (MS; n = 3), who were evaluated between January 1989 and December 2016; 11 patients were women and 6 were men. Thirteen patients had definitive MD (76%), one had unilateral MD (5.2%), and 3 had MS (18%). The condition manifested as intraparenchymal haemorrhage (in 35.2% of patients), brain ischaemia (29.4%), subarachnoid haemorrhage (17.6%), seizures (11.7%), and headache with no associated haemorrhage (1 patient). RESULTS: Ten patients (58.8%) underwent revascularisation and 7 (41.2%) received pharmacological treatment. All patients were evaluated with the modified Rankin Scale (mRs) at admission and at the last consultation; mRs scores were significantly lower in the group undergoing surgery (P <  .04). During follow-up, none of the patients undergoing revascularisation experienced recurrences, whereas 2 patients receiving pharmacological treatment did experience a new vascular event (one ischaemic and one haemorrhagic) (P <  .05). No significant differences were observed between the treatment outcomes of different revascularisation techniques. CONCLUSIONS: Although our population has different demographic characteristics from those of other non-Asian populations, ours is the largest published series of Hispanic individuals with MD. Our results support the use of revascularisation procedures to improve these patients' neurological status and to prevent new cerebrovascular events.

Hemorrhagic stroke associated to COVID-19 infection in Mexico General Hospital.

INTRODUCCIÓN: en la actual pandemia de COVID-19, existe evidencia creciente que ha identificado el neurotropismo del virus SARS-CoV-2 y sus complicaciones neurológicas, incluida la enfermedad cerebrovascular isquémica y escasamente hemorragia cerebral (HC). OBJETIVO: describir las características clínicas, radiológicas, de laboratorio y pronósticas de los pacientes con HC asociada al SARS-CoV-2. MÉTODOS: se incluyeron pacientes consecutivos con prueba de PCR confirmatoria para infección por SARS-CoV-2 y HC. RESULTADOS: en un período de 90 días, en un centro de referencia COVID-19 en México, de 1108 pacientes con infección por SARS-CoV-2, se encontraron 4 pacientes (0.36%) con HC. Tenían una edad de 71(±12.2) años, 2 eran mujeres. Se encontró que dos tenían factores de riesgo cardiovascular previos. En dos casos se encontró el origen en el núcleo dentado mientras que los otros dos correspondieron al tálamo. Tres de los cuatro pacientes murieron. Postulamos que el descontrol hipertensivo, coagulopatía, trombocitopenia y la respuesta inmune inducida por el virus SARS-CoV-2 podrían desencadenar HC en un paciente con riesgo previo. CONCLUSIONES: la HC se asocia a la infección por SARS-CoV-2 con mal pronóstico cuando se presenta. Los equipos de neurocirugía deben estar preparados para el tratamiento oportuno de estos pacientes. INTRODUCTION: In the current COVID-19 pandemic, there is a growing body of evidence that has identified the neurotropism of the SARS-CoV-2 virus and its neurological complications, including cerebrovascular disease, focusing mainly in ischemic and scarcely about hemorrhagic stroke (HS). OBJECTIVE: The objective of the study was to describe clinical, radiological, laboratory tests, and prognostic characteristics of patients with SARS-CoV-2 associated HS. METHODS: Consecutive patients with a confirmatory PCR test for SARS-CoV-2 infection and a HS demonstrated by head CT were included in the study. RESULTS: Over a period of 90 days, in a COVID-19 reference center in Mexico, out of a total of 1108 patients with SARS-CoV-2 infection, it found 4 patients (0.36%) who meet criteria. They had an age of 71 (±12.2) years, 2 were women. It was found that two had prior cardiovascular risk factors. Two of the HS originated in the dentate nucleus while the other two corresponded to the thalamus. Three of the four patients died. We suggest that catastrophic uncontrolled blood pressure, coagulopathy, thrombocytopenia, and immune response induced by SARS-CoV-2 could in a specific patient trigger HS. CONCLUSIONS: HS is associated to SARS-CoV-2 infection with poor prognosis when it presented. Neurosurgery teams should prepare for the timely and appropriate treatment of this patients.

AISYF: first national, prospective, multicenter study of young patients with stroke in Argentina / AISYF: primer estudio nacional, prospectivo y multicéntrico de pacientes jóvenes con ataque cerebral en Argentina

Abstract Up to 15% of all strokes affect young patients and the incidence of ischemic stroke in this population is rising. Nevertheless, there is limited information of cerebrovascular events in this population both in our country and in Latin America. The aim of our study was to evaluate the clinical characteristics and risk factors of young adults with stroke in Argentina. This is a prospective, multicenter study of stroke in young adults (18 - 55 years) in Argentina. Patients presenting with a cerebrovascular event within 180 days were included. Stroke subtypes were classified according to TOAST criteria. A total number of 311 patients were enrolled (men 53.9%, mean age: 43.3 years). Ischemic strokes occurred in 91.8% (brain infarcts 82.6%, transient ischemic attack 9.2%) and hemorrhagic strokes in 8.2%. The most frequent vascular risk factors (including ischemic and hemorrhagic strokes) were: hypertension 120 (41%), smoking 92 (31.4%), dyslipidemia 81 (27.6%) and, over weight/obesity: 74 (25.3%). Stroke subtypes were: large artery disease 12.3%, cardioembolism 7.5, small artery occlusion 11.5%, other defined etiology 27.1%, and undetermined etiology 41.6%. Our study demonstrates that vascular risk factors are very frequent in young adults with stroke. Our findings underline that urgent strategies are required for primary and secondary stroke prevention in this group of patients.

Resumen Aproximadamente un 15% de todos los ataques cerebrovasculares afectan a pacientes jóvenes y su incidencia estaría en aumento. Existe escasa información sobre el ataque cerebral en esta población tanto en nuestro país como en Latinoamérica. El objetivo de nuestro estudio fue evaluar las características clínicas y los factores de riesgo de los adultos jóvenes con ictus en Argentina. Realizamos un estudio prospectivo y multicéntrico en adultos jóvenes (18-55 años) en Argentina, que presentaron un evento cerebrovascular dentro de los 180 días previos. Los subtipos de ictus se clasificaron según los criterios de TOAST. Se incluyeron un total de 311 pacientes (hombres 53.9%, edad media: 43,3 años). Los ataques cerebrovasculares isquémicos ocurrieron en el 91.8% (infartos cerebrales 82.6%, ataque isquémico transitorio 9.2%) y los eventos hemorrágicos correspondieron al 8.2%. Los factores de riesgo vascular más frecuentes (incluyendo los eventos isquémicos y hemorrágicos) fueron: hipertensión 120 (41%), tabaquismo 92 (31.4%), dislipidemia 81 (27.6%) y sobrepeso/obesidad: 74 (25.3%). Los subtipos de ictus isquémicos fueron: arteriopatía de gran vaso 12.3%, cardioembolismo 7.5%, oclusión de pequeña arteria 11.5%, otra etiología definida 27.1% y etiología indeterminada 41.6%. Los factores de riesgo vascular son muy frecuentes en los adultos jóvenes con ictus. Nuestros hallazgos subrayan que se requieren estrategias urgentes para la prevención primaria y secundaria del ictus en este grupo particular de pacientes en nuestro país.

Vasoconstricción cerebral fatal, presentación inusual de una enfermedad inusual / Fatal reversible cerebral vasoconstriction syndrome: An unusual presentation of a rare disease

Resumen | El síndrome de vasoconstricción cerebral reversible se produce por la constricción variable, segmentaria y multifocal, de las arterias cerebrales y, generalmente, es de curso benigno. Se describe el caso de una mujer de 49 años que consultó por cefalea, síntomas visuales y convulsiones; tres días después, presentaba áreas de vasoconstricción en, por lo menos, dos territorios vasculares y dos segmentos de las mismas arterias. Fue internada en la unidad de cuidados intensivos para controlarle la presión arterial y recibir tratamiento médico. Tuvo una evolución tórpida y, en el séptimo día de hospitalización, desarrolló edema cerebral maligno, tras lo cual ocurrió la muerte cerebral. Se inició entonces el plan de donación de órganos y, posteriormente, se practicó una autopsia guiada del cerebro. El estudio de patología descartó vasculitis y reveló áreas de hemorragia en la convexidad cerebral. Se discuten los aspectos más relevantes de los casos con evolución fulminante informados en la literatura científica. El síndrome de vasoconstricción cerebral reversible se asocia con resultados fatales cuando los pacientes tienen una deficiencia neurológica focal, la neuroimagen inicial muestra alteraciones y hay un deterioro clínico rápido. Es importante conocer los factores asociados con un mal pronóstico, y establecer estrategias tempranas de intervención y prevención.

Abstract | The reversible cerebral vasoconstriction syndrome is a variable, segmental, and multifocal constriction of brain arteries, usually with a benign course. We describe the case of a 49-year-old woman who presented with headaches, visual symptoms, and seizures. Three days after admission, vasoconstriction areas were found in at least two vascular territories in two segments of the same arteries. The patient was admitted to the intensive care unit where her blood pressure was monitored and she received medical treatment. Surprisingly, the patient presented an unpredicted evolution in developing malignant cerebral edema on the seventh day after admission. She then suffered brain death and was taken to organ donation. A guided nervous system necropsy was later performed. The pathology discarded vasculitis and exhibited hemorrhage areas in the cerebral convexity. Herein, we discuss the most relevant aspects of cases with fulminant evolution reported in the literature. The reversible cerebral vasoconstriction syndrome is usually associated with fatal outcomes when patients exhibit focalization, their first neuroimaging typically shows disturbances, and a rapid clinical deterioration occurs. It is crucial to identify factors linked to poor prognosis and set intervention strategies and early prevention.

Caso raro: trauma penetrante craneoencefálico por un cuchillo. Actualización del diagnóstico y tratamiento / Rare case: penetrating head trauma by a knife. Diagnosis and treatment update

El trauma penetrante craneoencefálico representa alrededor del 0.4% de los casos, pocos son los descritos en la literatura, por lo cual, no existe un manejo protocolizado del mismo.Describimos un caso de un paciente masculino de 24 años que sufre un trauma penetrante a nivel de región parietal izquierda con arma blanca "cuchillo", dejando incrustada la hoja del mismo. La Tomografía computarizada simple de cráneo con reconstrucción en 3 dimensiones más angiografía, confirma el diagnóstico y descarta el compromiso vascular. Se realiza la extirpación completa del cuerpo extraño, sin complicaciones. Evolución favorable con mejoría de la sintomatología neurológica al alta.Este tipo de trauma es una emergencia que puede poner en riesgo la vida del paciente dependiendo del área afectada. La extirpación del cuerpo extraño debe realizarse en un medio hospitalario por la afectación de grandes vasos. Se debe tener una alta sospecha diagnóstica asociada al antecedente.

Craneoencephalic penetrating trauma represents about 0.4% of cases, few are described in the literature, therefore, there is no protocolized management of them.We describe a case of a 24-year-old male patient who suffers penetrating trauma at left parietal region with a "knife", leaving the blade embedded. Simple Computed Tomography of the Skull with Reconstruction in 3 dimensions plus angiography, confirms the diagnosis without vascular compromise. The complete removal of the foreign body was performed, without complications. Evolution is favorable and was discharged with improvement neurological symptoms.This type of trauma is an emergency that can put the life at risk depending on the affected area. The removal of the foreign body must be performed in a hospital environment due to the involvement of large vessels. There must be a high diagnostic suspicion associated with the antecedent.

Reporte de caso de hemorragia cerebral como presentación inicial de meningioma en un hospital de III nivel en Colombia / Case report of cerebral hemorrhage as initial presentation of meningioma in an III level of care hospital in Colombia

RESUMEN La presentación inicial de los tumores cerebrales depende en gran medida de su localización y las estructuras que se encuentren adyacentes, y en algunos casos pueden tener un curso asintomático. Sin embargo, una de las causas poco frecuentes pero bien conocidas de hemorragias intracraneales espontáneas, es la presentación inicial de tumores cerebrales primarios y secundarios. En este artículo se presenta el caso de un paciente de 72 años que ingresó al servicio de urgencias con alteración del estado de conciencia y hemiparesia braquiocrural izquierda. Al examen físico presentó cifras tensionales elevadas, por lo que se realizó una tomografía de cráneo que puso en evidencia una lesión ocupante de espacio con efecto de masa y características que sugirió una hemorragia intratumoral, la cual requirió drenaje y resección del tumor extraaxial. Posteriormente, el resultado de la patología reveló un meningioma atípico grado II.

SUMMARY The initial presentation of brain tumors will depend especially on their location, adjacent structures or in some cases may have an asymptomatic course. However, one of the rare but well-known causes of spontaneous intracraneal hemorrhages is the initial presentation of primary and secondary brain tumors. This article presents the case of a 72-year-old patient who has entered to the emergency department with altered consciousness state and left brachio-crural hemiparesis, the patient in the vital signs has presented high-tension rates. The cranial CT has shown a space occupying lesion with mass effect and characteristics suggesting intratumoral hemorrhage that required drainage and resection of the extra-axial tumor. The result of the pathology revealed an atypical meningioma grade II.

Deficiencia visual y neurológica posterior a la disfunción del sistema de derivación ventrículoperitoneal: reporte de caso / Visual and neurological impairment post-dysfunction in the ventricle-peritoneal shunt system: A case report

Resumen | Las alteraciones visuales de origen neurológico en los niños tienen diversas causas, algunas reversibles y otras no. La hidrocefalia es una de las más comunes e importantes, ya que puede producir deficiencias permanentes. Las causas de la hidrocefalia son variadas; entre las principales está la hemorragia intraventricular, generalmente debida al sangrado de la matriz germinal, el cual es muy común en recién nacidos prematuros. Se presenta el caso clínico de una paciente prematura con parálisis cerebral infantil, hemorragia intraventricular e hidrocefalia, producto de un embarazo múltiple, que presentó atrofia óptica en la infancia secundaria a la disfunción del sistema de derivación ventrículo-peritoneal. Durante su rehabilitación y tratamiento, ha recibido sesiones de neurorrehabilitación que le han permitido mejorar su agudeza y capacidad visual. Se comparó el caso de la paciente con algunos similares para establecer las semejanzas y las diferencias entre los cuadros clínicos presentados y la importancia del tipo de tratamiento médico utilizado en el curso de recuperación de la capacidad visual.

Abstract | Neurological visual impairments in children have multiple causes, some of them reversible while others are not. Hydrocephalus is one of the most important and common ones as it can result in permanent impairment. There are multiple causes of hydrocephalus, intraventricular hemorrhage being the main one. This generally occurs when the germinal matrix bleeds and is very common in preterm newborns. We present the clinical case of a patient with cerebral palsy, intraventricular hemorrhage, and hydrocephalus as a result of a preterm multiple pregnancy who developed optic atrophy during childhood secondary to ventricle-peritoneal shunt dysfunction. During the rehabilitation and treatment period, she received neurorehabilitation sessions, which improved her visual acuity and capacity. We found similarities and differences with other cases and we confirmed the importance of the treatment chosen for the recovery of visual capacity.
