RESUMEN

PURPOSE: Encephaloceles are neural tube closure defects characterized by herniation of intracranial contents through the skull, with a mortality rate of 33.3%. Approximately 50% of patients who survived have some degree of neuropsychomotor developmental impairment or seizures. This study aimed to analyze the relationship between good neuropsychomotor development (NPMD) in patients undergoing fetal occipital encephalocele correction and the reversal of microcephaly, comparing these outcomes with those observed in patients who underwent postnatal surgery. METHODS: The 22 participants were categorized into two groups: 10 in the fetal group (FG) and 12 in the postnatal group (PNG). During the study, 1 patient was excluded from the FG and 2 patients were excluded from the PNG, totaling 19 patients in the study. All patients were diagnosed, evaluated, and monitored by the same healthcare service between July 2012 and July 2018. All participants were subjected to a careful developmental assessment using the Bayley Scale of Infant Development, Second Edition (BSID-II), up to 2 years and 11 months of age. Additionally, CP measurements were taken during the first year of life to monitor their progress. The relationship between microcephaly reversal and NPMD was studied. RESULTS: The CP adjusted for gestational age showed a tendency toward the reversal of progressive microcephaly after correction of encephaloceles in the FG. We found a statistically significant difference in the median BSID-II score between the PNG and FG. Patients in the FG maintained normal CP development in the first year of life, whereas those in the PNG remained microcephalic. CONCLUSION: The reversal of microcephaly in the FG directly influences good NPMD and can be considered a protective factor.

RESUMEN

INTRODUCTION: Blood transfusion is one of the most common medical practices worldwide. However, current scientific literature has shown that the immunomodulatory effects of blood transfusion are associated with an increased likelihood of infection, prolonged hospitalization, and morbimortality. Also, it means high costs for healthcare systems. METHODS: In this context, acknowledging that blood transfusions are essentially heterologous cell transplantations, the use of therapeutic options has gained strength and is collectively known as the patient blood management (PBM) program. PBM is an approach based on three main pillars: (1) treating anemias and coagulopathies in an optimized manner, especially in the preoperative period; (2) optimizing perioperative hemostasis and the use of blood recovery systems to avoid the loss of the patient's blood; (3) anemia tolerance, with improved oxygen delivery and reduced oxygen demand, particularly in the postoperative period. RESULTS: Current scientific evidence supports the effectiveness of PBM by reducing the need for blood transfusions, decreasing associated complications, and promoting more efficient and safer blood management. Thus, PBM not only improves clinical outcomes for patients but also contributes to the economic sustainability of healthcare systems. CONCLUSION: The aim of this review was to summarize PBM strategies in a comprehensive, evidence-based approach through a systematic and structured model for PBM implementation in tertiary hospitals. The recommendations proposed herein are from researchers and experts of a high-complexity university hospital in the network of the Sistema Único de Saúde, presenting itself as a strategy that can be followed as a guideline for PBM implementation in other settings.

RESUMEN

PURPOSE: To correlate behavioral assessment results of central auditory processing and the self-perception questionnaire after acoustically controlled auditory training. METHODS: The study assessed 10 individuals with a mean age of 44.5 years who had suffered mild traumatic brain injury. They underwent behavioral assessment of central auditory processing and answered the Formal Auditory Training self-perception questionnaire after the therapeutic intervention - whose questions address auditory perception, understanding orders, request to repeat statements, occurrence of misunderstandings, attention span, auditory performance in noisy environments, telephone communication, and self-esteem. Patients were asked to indicate the frequency with which the listed behaviors occurred. RESULTS: Figure-ground, sequential memory for sounds, and temporal processing correlated with improvement in following instructions, fewer requests to repeat statements, increased attention span, improved communication, and understanding on the phone and when watching TV. CONCLUSION: Auditory closure, figure-ground, and temporal processing had improved in the assessment after the acoustically controlled auditory training, and there were fewer auditory behavior complaints.


OBJETIVO: Correlacionar os resultados da avaliação comportamental do processamento auditivo central e do questionário de autopercepção após o treinamento auditivo acusticamente controlado. MÉTODO: Foram avaliados dez indivíduos com média de idade de 44,5 anos, que sofreram traumatismo cranioencefálico de grau leve. Os indivíduos foram submetidos a avaliação comportamental do processamento auditivo central e também responderam ao questionário de autopercepção "Treinamento Auditivo Formal" após a intervenção terapêutica. O questionário foi composto por questões referentes a percepção auditiva, compreensão de ordens, solicitação de repetição de enunciados, ocorrência mal-entendidos, tempo de atenção, desempenho auditivo em ambiente ruidoso, comunicação ao telefone e autoestima e os pacientes foram solicitados a assinalar a frequência de ocorrência dos comportamentos listados. RESULTADOS: As habilidades auditivas de figura-fundo e memória para sons em sequência e processamento temporal correlacionaram-se com melhora para seguir instruções, diminuição das solicitações de repetições e aumento do tempo de atenção e melhora da comunicação e da compreensão ao telefone e para assistir TV. CONCLUSÃO: Observou-se adequação das habilidades auditivas de fechamento auditivo, figura fundo, e processamento temporal na avaliação pós-treinamento auditivo acusticamente controlado, além de redução das queixas quanto ao comportamento auditivo.

RESUMEN

Background: Intraventricular hemorrhage (IVH) is a complex condition with both mechanical and chemical effects, resulting in mortality rates of 50-80%. Recent reports advocate for neuroendoscopic treatment, particularly endoscopic brainwashing (EBW), but long-term functional outcomes remain insufficiently explored. This study aims to outline the step-by-step procedure of EBW as applied in our institution, providing results and comparing them with those of external ventricular drainage (EVD) alone. Methods: We performed a retrospective analysis of adult patients with IVH who underwent EBW and patients submitted to EVD alone at our institution. All medical records were reviewed to describe clinical and radiological characteristics. Results: Although both groups had similar baseline factors, EBW patients exhibited a larger hemoventricle (median Graeb score 25 vs. 23 in EVD, P = 0.03) and a higher prevalence of chronic kidney disease and diabetes. Short-term mortality was lower in EBW (52% and 60% at 1 and 6 months) compared to EVD (80% for both), though not statistically significant (P = 0.06). At one month, 16% of EBW patients achieved a good outcome (Modified Rankin scale < 3) versus none in the EVD group (P = 0.1). In the long term, favorable outcomes were observed in 32% of EBW patients and 11% of EVD patients (P = 0.03), with no significant difference in shunt dependency. Conclusion: Comparing EBW and EVD, patients submitted to the former treatment have the highest modified Graeb scores and, at a long-term follow-up, have better outcomes, demonstrated by the improvement of the patients in the follow-up.

RESUMEN

Among fetal surgical procedures, neurosurgery stands out due to the number of cases and the possibility of developing new procedures that can be performed in the fetal period. To perform fetal neurosurgical procedures, there is a need for specialized centers that have experts in the diagnosis of fetal pathologies and a highly complex obstetrics service with specialized maternal-fetal teams associated with a pediatric neurosurgery center with expertise in the diverse pathologies of the fetus and the central nervous system that offers multidisciplinary follow-up during postnatal life. Services that do not have these characteristics should refer their patients to these centers to obtain better treatment results. It is essential that the fetal neurosurgical procedure be performed by a pediatric neurosurgeon with extensive experience, as he will be responsible for monitoring these patients in the postnatal period and for several years. The objective of this manuscript is to demonstrate the diagnostic and treatment possibilities, in the fetal period, of some neurosurgical diseases such as hydrocephalus, tumors, occipital encephalocele, and myelomeningocele.

RESUMEN

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.


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 (42­68) anos. O tempo médio entre o ictus e a craniectomia descompressiva foi 41,88 (6­77) horas. O tempo médio entre o ictus e o pico do volume hemisférico foi 168,84 (142,08­195,59) 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.

RESUMEN

PURPOSE: The recent history of myelomeningocele has shown that treatment during the fetal life may reduce the risk of developing hydrocephalus in individuals by approximately 50%. Thus, a significant advancement involves fetal surgery performed through an endoscopic technique in which portals are placed to introduce the forceps and laparoscopic instruments. However, the development of this technique requires training; therefore, this study aimed to develop a training model for fetal myelomeningocele repair technique with multi-portal endoscopy. METHODS: Two stages of endoscopic technique development were performed. The first stage consisted of exercises in order to familiarize the surgeon with 2D-vision endoscopic surgery, associated with the application of exercises focused on surgical skills, such as the development of laparoscopic knots in a synthetic model. The second stage involved the creation and application of the stages of myelomeningocele closure with a non-living animal model consisting of a chicken breast to simulate the myelomeningocele and a basketball to simulate the gravid uterus, in which perforations were made to introduce vascular introducers (portals) that, as in vivo, are used as portals (trocars) for the introduction of laparoscopic instruments. Overall, two different scenarios with three portals and two portals were tested. RESULTS: In three-portal simulator, the triangular apex trocar was used for the introduction of 4-mm 0° or 30° optics or even Minop type neurodoscope (Aesculap®, Germany) that was operated by the assistant surgeon; the other two portals are used for the introduction of laparoscopic instruments. Thus, the surgeon is able to perform maneuvers bimanually since dissection to laparoscopic sutures. In two-portal simulator, the surgeon and assistant stay side by side and one of the portals is used for the optic and the other for the laparoscopic instruments. There is no possibility of bimanual dissection in this method. CONCLUSION: Realistic simulation models for endoscopic fetal surgery for myelomeningocele correction are easily performed and help develop the necessary skills for fetal surgery teams.

RESUMEN

Background: Malignant middle cerebral artery (MCA) infarction is associated with high mortality, mainly due to intracranial hypertension. This malignant course develops when two-thirds or more of MCA territory is infarcted. Randomized clinical trials demonstrated that in patients with malignant MCA infarction, decompressive craniectomy (DC) is associated with better prognosis. In these patients, some prognostic predictors are already known, including age and time between stroke and DC. The size of bone flap was not associated with long-term prognosis in the previous studies. Therefore, this paper aims to further expand the analysis of the bone removal toward a more precise quantification and verify the prognosis implication of the bone flap area/whole supratentorial hemicranium relation in patients treated with DC for malignant middle cerebral infarcts. Methods: This study included 45 patients operated between 2015 and 2020. All patients had been diagnosed with a malignant MCA infarction and were submitted to DC to treat the ischemic event. The primary endpoint was dichotomized modified Rankin scale (mRS) 1 year after surgery (mRS≤4 or mRS>4). Results: Patients with bad prognosis (mRS 5-6) were on average: older and with a smaller decompressive craniectomy index (DCI). In multivariate analysis, with adjustments for "age" and "time" from symptoms onset to DC, the association between DCI and prognosis remained. Conclusion: In our series, the relation between bone flap size and theoretical maximum supratentorial hemicranium area (DCI) in patients with malignant MCA infarction was associated with prognosis. Further studies are necessary to confirm these findings.

RESUMEN

BACKGROUND: A subdural hematoma is defined as clot formation in the subdural space after vessel rupture or brain parenchyma damage. Several demographic and tomographic factors were associated to poor prognosis, although some debate according to their specific roles still remains. METHODS: Retrospective cohort study of comatose patients admitted to a single-institution, tertiary hospital center, between the years 2013 and 2019 with traumatic acute subdural hematoma requiring surgical evacuation were studied. Demographic and tomographic data were obtained from medical records. Univariate and multivariate statistical analysis were performed, using a value of P < 0.05 for significance. RESULTS: Seventy-seven patients were selected using the criteria and a total of 37 (48%) head CT exams were evaluated. The overall mortality was 57.1% and achieved 100% at ≥75-years-old subgroup. Univariate analysis only found young age as a good prognosis factor (P = 0.002). Gender (P = 0.784), abnormal pupillary response (P = 0.643), midline shift (P = 0.874), clot thickness (P = 0.206), compressed basal cisterns (P = 0.643), hematoma side (P = 0.879), and subarachnoid hemorrhage (P = 0.510) showed no association. Multivariate analysis showed no statistically significant association between covariates. CONCLUSION: Traumatic acute subdural hematoma is a life-threatening condition. Younger age was the only positive prognostic factor identified. More research is necessary to establish age as a rule-out criterion to surgical indication.

RESUMEN

Arachnoid cysts are responsible for 1% of expansive lesions in the central nervous system. Usually, they do not cause neurologic symptoms unless they have expansion or hemorrhage. Intracystic bleeding is caused by trauma or may be spontaneous. There are few cases in the literature of spontaneous hemorrhage of arachnoid cysts. This 2-dimensional video (Video 1) demonstrates the case of a 6-year-old boy who presented with headache and diplopia. At the physical examination, he exhibited right sixth nerve palsy. The complementary examinations revealed a left middle fossa arachnoid cyst classified as Galassi 2. An urgent procedure was planned to fenestrate the cyst. Informed written consent was obtained from the patient's family. Due to the team experience, endoscope-controlled microsurgery was performed. The patient experienced remission of the headache and the diplopia. A CT scan was performed on the first postoperative day and revealed a lamina of acute blood at the subdural space. It was an asymptomatic thin lamina of blood; we opted to watch and follow. One month later, a control MRI revealed a left frontoparietal subdural hematoma. Despite being asymptomatic, the hematoma was determined to have significant mass effect; thus, it was evacuated by a parietal burr-hole. After 1 month, another MRI showed resolution of the frontoparietal hematoma and significant reduction in the arachnoid cyst. There are few cases described of spontaneous rupture of arachnoid cyst; beyond that, we would like to illustrate a step-by-step procedure that is not widely available as a video article.

RESUMEN

PURPOSE: The aim of this study was to analyze the skull base anatomy of patients who underwent intrauterine or postnatal myelomeningocele repair and to determine its relationship with hydrocephalus. METHODS: This was a retrospective cross-sectional study that analyzed three groups: the postnatal group, 57 patients who underwent myelomeningocele repair up to 48 h after birth; the fetal group, 70 patients who underwent myelomeningocele repair between 19 and 27 weeks of gestation; and a control group (65). We compared the rate of hydrocephalus treatment, the clivus-supraocciput angle (CSA), and the Welcher angle. RESULTS: The mean CSA in the fetal group was 87.6°, and the postnatal group was significantly different at 78.3° (p < 0.0001). The control group (89.1°) was significantly different from the postnatal group but not from the fetal group. The mean Welcher angle was not significantly different between the groups. There was an 8.5% rate of surgical treatment for hydrocephalus in the fetal group, compared with 73.6% in the postnatal group. CONCLUSIONS: The CSA in the fetal group was larger than that in the postnatal group, which may explain the decrease in the prevalence of hydrocephalus in the fetal group.

RESUMEN

OBJECTIVES: Idiopathic intracranial hypertension refers to cases of intracranial hypertension and normal brain parenchyma without ventriculomegaly or any kind of mass lesion. Perineural cysts are cerebrospinal fluid-filled cysts that usually arise from nerve roots near the dorsal ganglia. Often asymptomatic, they rarely cause mass effect symptoms. The association of these conditions is discussed herein. METHODS: We describe 2 patients with idiopathic intracranial hypertension and symptomatic sacral perineural cysts. In both cases the treatment of idiopathic intracranial hypertension ameliorated the sacral perineural cyst symptoms, and in 1 case we observed shrinking of the sacral perineural cysts. RESULTS: On the basis of this review, it is impossible to conclude whether there is an association between idiopathic intracranial hypertension and symptomatic perineural cysts. However, as an initial observation, this report can reveal a possible association. CONCLUSIONS: In some instances, idiopathic intracranial hypertension can be associated with symptomatic sacral perineural cysts. In this clinical scenario, the treatment of idiopathic intracranial hypertension may improve perineural cyst symptoms.

RESUMEN

The advance in the imaging tools during the pregnancy (ultrasound and magnetic resonance) allowed the early diagnose of many fetal diseases, including the neurological conditions. This progress brought the neurosurgeons the possibility to propose treatments even before birth. Myelomeningocele is the most recognized disease that can be treated during pregnancy with a high rate of success. Additionally, this field can be extended to other conditions such as hydrocephalus and encephaloceles. However, each one of these diseases has nuances in the diagnostic evaluation that should fit the requirements to perform the fetal procedure and overbalance the benefits to the patients. In this article, the authors aim to review the neurosurgical aspects of the antenatal management of neurosurgical conditions based on the experience of a pediatric neurosurgery center.

RESUMEN

Epidermoid cyst is a benign and congenital lesion of ectodermal origin. Traditionally, microsurgical techniques are used to treat these lesions, and their occurrence in the third ventricle is rare. Here, the authors report a case of epidermoid cyst in the third ventricle that presented with signs and symptoms of intracranial hypertension, which was treated safely and effectively using neuroendoscopic surgery.

RESUMEN

OBJECTIVE: To investigate the long-term efficacy of acoustically controlled auditory training in adults after tarumatic brain injury. METHODS: A total of six audioogically normal individuals aged between 20 and 37 years were studied. They suffered severe traumatic brain injury with diffuse axional lesion and underwent an acoustically controlled auditory training program approximately one year before. The results obtained in the behavioral and electrophysiological evaluation of auditory processing immediately after acoustically controlled auditory training were compared to reassessment findings, one year later. RESULTS: Quantitative analysis of auditory brainsteim response showed increased absolute latency of all waves and interpeak intervals, bilaterraly, when comparing both evaluations. Moreover, increased amplitude of all waves, and the wave V amplitude was statistically significant for the right ear, and wave III for the left ear. As to P3, decreased latency and increased amplitude were found for both ears in reassessment. The previous and current behavioral assessment showed similar results, except for the staggered spondaic words in the left ear and the amount of errors on the dichotic consonant-vowel test. CONCLUSION: The acoustically controlled auditory training was effective in the long run, since better latency and amplitude results were observed in the electrophysiological evaluation, in addition to stability of behavioral measures after one-year training.
