Hemorragia intracraniana espontânea em pediatria: relato de paciente hemofílico que sobreviveu devido a cisto cerebral / Spontaneous intracranial hemorrhage in children: report of a hemophilia patient who survived due to a brain cyst

RESUMO Relatamos o caso de um uma criança de 2 anos de idade que sobreviveu após um episódio agudo de hemorragia intracraniana espontânea grave com sinais clínicos e radiológicos de hipertensão intracraniana e herniação transtentorial. O paciente foi para cirurgia de urgência para drenagem do hematoma, sendo inserido um cateter para monitorar a pressão intracraniana. Na análise da tomografia de crânio inicial, antes da drenagem do hematoma, constatou-se um cisto cerebral contralateral ao hematoma que, segundo análise do neurocirurgião e do neuroradiologista, possivelmente evitou um desfecho pior, visto que o cisto serviu de acomodação para o cérebro após a hemorragia maciça. Após investigação, constatou-se tratar de um caso de hemofilia tipo A sem diagnóstico prévio. O paciente foi tratado em terapia intensiva com controle da pressão intracraniana, reposição de fator VIII e obteve alta sem sequelas neurológicas evidentes.

ABSTRACT We report the case of a 2-year-old child who survived an acute episode of severe spontaneous intracranial hemorrhage with clinical and radiological signs of intracranial hypertension and transtentorial herniation. The patient underwent emergency surgery to drain the hematoma, and a catheter was inserted to monitor intracranial pressure. In the initial computed tomography analysis performed prior to hematoma drainage, a brain cyst was evident contralateral to the hematoma, which, based on the analysis by the care team, possibly helped to avoid a worse outcome because the cyst accommodated the brain after the massive hemorrhage. After the investigation, the patient was determined to have previously undiagnosed hemophilia A. The patient underwent treatment in intensive care, which included the control of intracranial pressure, factor VIII replacement and discharge without signs of neurological impairment.

Craniectomía descompresiva en el trauma encefalocraneano grave: factores pronósticos y complicaciones / Decompressive craniectomy in severe traumatic brain injury: prognostic factors and complications

RESUMEN Objetivo: Análisis de las características clínicas, las complicaciones y los factores asociados al pronóstico de los pacientes con trauma encefalocraneano grave en los que se realizó craniectomía descompresiva. Métodos: Estudio retrospectivo de los pacientes asistidos en una Unidad de Cuidados Intensivos, con trauma encefalocraneano grave en los que se realizó craniectomía descompresiva, entre los años 2003 y 2012. Se siguieron los pacientes hasta el egreso de la unidad de cuidados intensivos, analizándose sus características clínico-tomográficas, las complicaciones y los factores asociados al pronóstico (análisis uni y multivariado). Resultados: Se estudiaron 64 pacientes. Se realizó craniectomía descompresiva primaria y lateral en la mayoría de los pacientes. Se halló una alta incidencia de complicaciones (78% neurológicas y 52% no neurológicas). 42 pacientes (66%) presentaron mala evolución y 22 (34%) tuvieron una buena evolución neurológica. De los pacientes que sobrevivieron, el 61% tuvo una buena evolución neurológica. En el análisis univariado, los factores asociados significativamente con mala evolución neurológica fueron: la hipertensión intracraneana post-craniectomía descompresiva, la mayor gravedad y el peor estado neurológico al ingreso. En el análisis multivariado, solo la hipertensión intracraneana post-craniectomía descompresiva se asoció significativamente con mala evolución. Conclusión: Se trata de un grupo de pacientes muy grave, de difícil manejo, con elevada morbimortalidad, donde la hipertensión intracraneana es un factor principal de mala evolución. .

ABSTRACT Objective: To analyze the clinical characteristics, complications and factors associated with the prognosis of severe traumatic brain injury among patients who undergo a decompressive craniectomy. Methods: Retrospective study of patients seen in an intensive care unit with severe traumatic brain injury in whom a decompressive craniectomy was performed between the years 2003 and 2012. Patients were followed until their discharge from the intensive care unit. Their clinical-tomographic characteristics, complications, and factors associated with prognosis (univariate and multivariate analysis) were analyzed. Results: A total of 64 patients were studied. Primary and lateral decompressive craniectomies were performed for the majority of patients. A high incidence of complications was found (78% neurological and 52% nonneurological). A total of 42 patients (66%) presented poor outcomes, and 22 (34%) had good neurological outcomes. Of the patients who survived, 61% had good neurological outcomes. In the univariate analysis, the factors significantly associated with poor neurological outcome were postdecompressive craniectomy intracranial hypertension, greater severity and worse neurological state at admission. In the multivariate analysis, only postcraniectomy intracranial hypertension was significantly associated with a poor outcome. Conclusion: This study involved a very severe and difficult to manage group of patients with high morbimortality. Intracranial hypertension was a main factor of poor outcome in this population. .

Evaluation of prognostic factors of decompressive craniectomy in the treatment of severe traumatic brain injury / Avaliação dos fatores prognósticos da craniectomia descompressiva no tratamento do traumatismo cranioencefálico grave

OBJECTIVE: to determine predictive factors for prognosis of decompressive craniectomy in patients with severe traumatic brain injury (TBI), describing epidemiological findings and the major complications of this procedure. METHODS: we conducted a retrospective study based on analysis of clinical and neurological outcome, using the extended Glasgow outcome in 56 consecutive patients diagnosed with severe TBI scale treated in the emergency department from February 2004 to July 2012. The variables assessed were age, mechanism of injury, presence of pupillary changes, Glasgow coma scale (GCS) score on admission, CT scan findings (volume, type and association of intracranial lesions, deviation from the midline structures and classification in the scale of Marshall and Rotterdam). RESULTS: we observed that 96.4% of patients underwent unilateral decompressive craniectomy (DC) with expansion duraplasty, and the remainder to bilateral DC, 53.6% of cases being on the right 42.9% on the left, and 3.6% bilaterally, with predominance of the fourth decade of life and males (83.9%). Complications were described as transcalvarial herniation (17.9%), increased volume of brain contusions (16.1%) higroma (16.1%), hydrocephalus (10.7%), swelling of the contralateral lesions (5.3%) and CSF leak (3.6%). CONCLUSION: among the factors studied, only the presence of mydriasis with absence of pupillary reflex, scoring 4 and 5 in the Glasgow Coma Scale, association of intracranial lesions and diversion of midline structures (DML) exceeding 15mm correlated statistically as predictors of poor prognosis. .

OBJETIVO: determinar fatores preditivos de prognóstico da craniectomia descompressiva, em pacientes com traumatismo cranioencefálico grave (TCE) descrevendo achados epidemiológicos e as principais complicações do método. MÉTODOS: estudo retrospectivo mediante análise da evolução clínica e neurológica, utilizando a escala estendida de resultados de Glasgow em 56 pacientes consecutivos atendidos no Serviço de Emergência no período de fevereiro de 2004 a julho de 2012, diagnosticados com TCE grave. Os fatores avaliados foram a idade, o mecanismo de trauma, a presença de alterações pupilares, a pontuação na escala de coma de Glasgow (ECG) à admissão, achado tomográfico (volume, tipo e associação de lesões intracranianas, desvio das estruturas da linha média e classificação na escala de Marshall e Rotterdam). RESULTADOS: observou-se que 96,4% dos casos foram submetidos à craniectomia descompressiva (CD) unilateral com duroplastia de expansão e o restante, CD bilateral, sendo 53,6% dos casos à direita, 42,9% à esquerda e 3,6% bilateralmente, com predomínio até a quarta década de vida e sexo masculino (83,9%). As complicações descritas foram a herniação transcalvárica (17,9%), aumento do volume de contusões cerebrais (16,1%), higroma (16,1%), hidrocefalia (10,7%), aumento de volume de lesões contralaterais (5,3%) e fístula liquórica (3,6%). CONCLUSÃO: entre os fatores estudados, apenas a presença de midríase com ausência de reflexo fotomotor, pontuação 4 e 5 na escala de coma de Glasgow, associação de lesões intracranianas e desvio de estruturas da linha mediana (DLM) superior a 15mm correlacionaram-se estatisticamente como fatores preditivos de prognóstico ...
