Objetivo: Determinar o perfil epidemiológico de pacientes atendidos pelo Sistema Único de Saúde (SUS), em determinado município do interior de Minas Gerais, bem como os gastos financeiros e o repasse financeiro para os centros de atendimento de traumas. Material e métodos: Trata-se de um estudo ecológico, descritivo, realizado a partir da coleta de dados pelo SIH-SUS, no período de janeiro de 2011 a dezembro de 2021, em um município do interior de Minas Gerais. Resultados: Foi identificado um total de 14.138 pacientes, com maior acometimento de pessoas do sexo masculino, com idade entre 15 e 44 anos. Como causas mais frequentes, destacaram-se os traumatismos de quadril e coxa, seguidos de traumatismos de membros superiores (ombro, antebraço, braço, punho e mão) e cabeça. Como tempo médio de permanência hospitalar, houve 4.693 diárias entre 2011 e 2021 secundárias a complicações em enfermarias e unidade de terapia intensiva, elevando cerca de 2,37% os valores repassados pelo SUS no período estudado. Em resumo, a análise da incidência de traumas nas emergências de um município do interior de Minas Gerais revela uma preocupante tendência em que homens na faixa etária de 15 a 44 anos emergem como as principais vítimas. Esse padrão pode ser influenciado por fatores como ocupação, comportamentos de risco e mobilidade. Conclusão: A compreensão dessa demografia específica é crucial para direcionar estratégias de prevenção e resposta adequadas. A implementação de medidas educativas, segurança no trânsito e promoção da saúde mental pode contribuir para mitigar os impactos dos traumas nesse grupo demográfico, melhorando sua qualidade de vida e a saúde geral da comunidade.

Objective: To determine the epidemiological profile of patients assisted by the unified health system, in a certain municipality in the interior of Minas Gerais, as well as the financial expenses and the financial transfer to trauma care centers. Material and methods: This is an ecological, descriptive study, carried out from data collection by SIH-SUS, from January 2011 to December 2021 in a municipality in the interior of Minas Gerais. Results: a total of 14,138 patients were identified, with greater involvement of male people aged between 15 and 44 years. As the most frequent causes, trauma to the hip and thigh stood out, followed by trauma to the upper limbs (shoulder, forearm, arm, wrist and hand) and head. As for the average length of hospital stay, there were 4,693 daily stays between 2011 and 2021 secondary to complications in wards and the intensive care unit. Increasing about 2.37% in the values transferred by the unified health system between the studied decade. In summary, the analysis of the incidence of trauma in emergencies in a municipality in the interior of Minas Gerais reveals a worrying trend in which men aged 15 to 44 years emerge as the main victims. This pattern can be influenced by factors such as occupation, risky behavior and mobility. Conclusion: Understanding this specific demographic is crucial to targeting appropriate prevention and response strategies. The implementation of educational measures, road safety and mental health promotion can help to mitigate the impacts of trauma in this demographic group, improving their quality of life and the general health of the community.

Research progress in characteristics and field surgical treatment of craniocerebral war injury in foreign armies / 中华创伤杂志

Craniocerebral war injury, mainly caused by weaponry equipment and wartime conditions during warfare, are characterized by high difficulty in treatment and evacuation as well as high mortality rate. The field surgical treatment of craniocerebral war injury is not only related to injury characteristics, but also to factors such as war scale, combat style, combat area and weapon power. In recent years, there have been few comprehensive reports on the characteristics and field surgical treatment of craniocerebral war injury in China. Therefore, the authors reviewed the research progress in the characteristics and field surgical treatment of craniocerebral war injuries in foreign armies since 2001, with the aim to provide a reference for relevant basic researches and war injury treatment in China.

Trans-base and trans-vault low-velocity penetrating brain injury: A retrospective comparative study of characteristics, treatment, and outcomes / 中华创伤杂志(英文版)

PURPOSE@#Low-velocity penetrating brain injury (LVPBI) caused by foreign bodies can pose life-threatening emergencies. Their complexity and lack of validated classification data have prevented standardization of clinical management. We aimed to compare the trans-base and trans-vault phenotypes of LVPBI to help provide guidance for clinical decision-making of such injury type.@*METHODS@#A retrospective study on LVPBI patients managed at our institution from November 2013 to March 2020 was conducted. We included LVPBI patients admitted for the first time for surgery, and excluded those with multiple injuries, gunshot wounds, pregnancy, severe blunt head trauma, etc. Patients were categorized into trans-base and trans-vault LVPBI groups based on the penetration pathway. Discharged patients were followed up by outpatient visit or telephone. The data were entered into the Electronic Medical Record system by clinicians, and subsequently derived by researchers. The demography and injury characteristics, treatment protocols, complications, and outcomes were analyzed and compared between the two groups. A t-test was used for analysis of normally distributed data, and a Mann-Whitney U test for non-parametric data. A generalized linear model was further established to determine whether the factors length of stay and performance scale score were influenced by each factor.@*RESULTS@#A total of 27 LVPBI patients were included in this analysis, comprised of 13 (48.1%) trans-base cases and 14 (51.9%) trans-vault cases. Statistical analyses suggested that trans-base LVPBI was correlated with deeper wounds; while the trans-vault phenotype was correlated with injury by metal foreign bodies. There was no difference in Glasgow Coma Scale score and the risk of intracranial hemorrhage between the two groups. Surgical approaches in the trans-base LVPBI group included subfrontal (n = 5, 38.5%), subtemporal (n = 5, 38.5%), lateral fissure (n = 2, 15.4%), and distal lateral (n = 1, 7.7%). All patients in the trans-vault group underwent a brain convex approach using the foreign body as reference (n = 14, 100%). Moreover, the two groups differed in application prerequisites for intracranial pressure monitoring and vessel-related treatment. Trans-base LVPBI was associated with higher rates of cranial nerve and major vessel injuries; in contrast, trans-vault LVPBI was associated with lower functional outcome scores.@*CONCLUSION@#Our findings suggest that trans-base and trans-vault LVPBIs differ in terms of characteristics, treatment, and outcomes. Further understanding of these differences may help guide clinical decisions and contribute to a better management of LVPBIs.

Middle meningeal vein dural arteriovenous fistula: A report of nine cases and literature review / 第二军医大学学报

Objective To summarize the clinical symptoms, imaging features and endovascular treatment outcomes of the middle meningeal vein dural arteriovenous fistula (MMV-DAVF). Methods The data of nine MMV-DAVF patients admitted to our hospital from Jan. 1999 to Apr. 2020 were retrospectively collected. A total of 16 Chinese and English articles, including 23 cases of MMV-DAVF, were retrieved from the database between Jan. 1, 1960 and Aug. 30, 2020. The clinical symptoms, imaging features and endovascular treatment outcomes were analyzed. Results Of the nine MMV-DAVF patients in our hospital, seven patients had a clear history of head trauma. Headache (five cases) and intracranial murmur (five cases) were the most common clinical symptoms. Six patients had computed tomography (CT) data, and four of them had skull fracture and five had intracranial hemorrhage. All the nine patients were drained from the middle meningeal vein (MMV) to adjacent venous sinus or venous plexus. The nine patients were treated with Onyx-18 glue endovascular intervention via middle meningeal artery (MMA) approach, and seven patients had complete embolization immediately after operation and two had subtotal embolization. No recurrence or new onset of DAVF was found in four patients having CT data half a year after operation. Among the 32 patients from our hospital and literatures, 26 patients (81.2%) had a clear history of head trauma, 16 patients (50.0%) suffered from headache, and 12 patients (37.5%) suffered from intracranial murmur. Twenty-five patients had CT data, including 21 patients (84.0%) with skull fracture, 16 patients (64.0%) with intracranial hematoma. Twenty patients (62.5%) were treated with endovascular interventional therapy via MMA approach, and 16 patients (80.0%) had complete embolization immediately after operation. Among them, seven cases had imaging follow-up data half a year after operation, and no recurrence or new onset of DAVF was found. Conclusion MMV-DAVF is rare, and many patients have head trauma history combined with skull fracture or intracranial hematoma. Endovascular embolization via MMA approach is safe and effective in treating MMV-DAVF.

Remoção de corpo estranho transfixante em dorso nasal: relato de caso / Removal of transfixing foreign body into nasal dorsum: case report

Os ferimentos transfixantes (FTs) em tecidos moles podem ser característicos em indivíduos admitidos em serviços de emergência hospitalar devido à grande morbidade e ao incômodo que podem ocasionar. Apesar de esse tipo de trauma não apresentar grande incidência, as suas implicações podem proporcionar sequelas funcionais e danos cosméticos à face do indivíduo. O objetivo do presente trabalho é descrever, por meio de relato de caso, a conduta adotada para paciente vítima acidental de ferimento transfixante, em terço médio de face, por objeto pontiagudo utilizado no local em que trabalhava. Relato de caso: indivíduo do sexo masculino, 47 anos de idade, normossistêmico e feoderma buscou atendimento em um serviço hospitalar de emergência com a presença de um gancho de açougue transfixado no nariz, penetrando a região de mucosa da narina direita até a pele do dorso nasal, relatando apenas queixa álgica e interesse em remover o objeto, sem obstrução de vias aéreas ou comprometimento de outras estruturas faciais. O gancho foi removido sob anestesia local, por um cirurgião bucomaxilofacial, havendo a preservação do septo nasal durante o procedimento e realização de sutura na lesão de pele do dorso nasal. Considerações finais: apesar de não haver um protocolo clínico-cirúrgico estabelecido quanto ao manejo de pacientes com FTs, é preconizado que o cirurgião se proponha a realizar a remoção do objeto sob conduta conservadora com o intuito de preservar ao máximo de estruturas nobres possíveis, assim como o presente caso foi conduzido.(AU)

Soft tissues transfixing wounds (TWs) may be characteristic in individuals admitted to emergency departments due to the high morbidity and discomfort they can cause. Although this type of trauma does not present a high incidence, its implications can provide sequels and cosmetic damages to the face. The aim of the present study is to describe, by means of a case report, the approach adopted for a patient who was accidentally transfixed, in a middle third of the face, by a sharp object used in the place where he worked. Case report: Male, 47 years old and normossemic, sought care in an emergency hospital service presenting a meat hook transfixed in his nose, penetrating the right nasal mucosa region up to the nasal skin dorsum, only reporting interest in removing the object and pain, without presenting airway obstruction or commitment of another facial structures. Regarding the clinical conditions of the present case, the hook was removed under local anesthesia by an oral and maxillofacial surgeon, preserving the nasal septum during the procedure and suturing the lesion in the nasal skin dorsum. Final considerations: Although there is no established clinical-surgical protocol regarding the management of patients with TWs, it is recommended that the surgeon proposes to remove the object under conservative management in order to preserve the maximum possible anatomic structures, as well as this case was conducted.(AU)

Spontaneous Disappearance of an Arachnoid Cyst after Burr Hole Drainage of Chronic Subdural Hematoma / 대한신경손상학회지

It is well known that the presence of arachnoid cysts (ACs) in young patients is a risk factor for developing a chronic subdural hematoma (CSDH) after a minor head injury. Although there have been controversies with the treatment, most authors recommend only draining the CSDH if the AC is asymptomatic. This judgement is based on the facts that this surgical approach has shown good clinical outcomes, and the AC usually remains unchanged after the surgery. Our case demonstrates that the AC of a young patient who developed a CSDH after a minor head injury completely disappeared after a burr hole drainage of the CSDH. Although the chances of an AC disappearing are low, this case shows that an AC might disappear after only draining a CSDH when a rupture of the AC membrane is identified. In such cases, we recommend first draining only the CSDH for the treatment of AC-associated CSDHs.

Evolução da vítima com trauma cranioencefálico na sala de emergência / Evolution of the victim with traumatic brain injury in the emergency room

Introdução: A frequência de vítimas de traumatismo cranioencefálico (TCE) nos serviços de emergência vem aumentando no mundo e conhecer a evolução dessas vítimas nas primeiras horas após lesão é um caminho importante para padronizar sua avaliação e alcançar melhores resultados no seu tratamento. Objetivos: Analisar, durante permanência na sala de emergência (SE), a evolução das vítimas que apresentaram TCE contuso como lesão principal e identificar, entre as variáveis demográficas, os indicadores de gravidade e as características do atendimento pré e intra-hospitalar, os fatores associados ao tempo de permanência na SE dessas vítimas. Método: Estudo do tipo corte prospectivo, com dados coletados na admissão da vítima de TCE na SE e 2, 4 e 6 horas após, ou até a transferência para tratamento definitivo em unidades específicas, ou óbito. Participaram desse estudo vítimas de TCE contuso como lesão principal, com idade 15 anos, admitidas em serviço de emergência referência para neurocirurgia, até 1 hora após trauma. A evolução das vítimas foi descrita pelas diferenças na pontuação Rapid Emergency Medicine Score (REMS) entre as avaliações na admissão na SE e 2, 4 e 6 horas após. Análises descritivas foram utilizadas para caracterização dos casos e descrever a evolução das vítimas. Testes estatísticos foram aplicados para verificar associação entre tempo de permanência na SE e idade, sexo, gravidade e características do atendimento pré e intra-hospitalar. Resultados: A casuística foi composta de 46 vítimas, 84,7% do sexo masculino, idade média de 34,7 anos (dp=15,1), 63% envolvidas em acidentes de trânsito. Na admissão na SE, o REMS médio dessas vítimas foi de 4,0 (dp=2,5), as médias do Injury Severity Score (ISS) e New Injury Severity Score (NISS) foram de 11,8 (dp=7,7) e 17,2 (dp=12,7), respectivamente. A Escala de Coma de Glasgow(ECGl) indicou 54,4% de casos de TCE grave e o Maximum Abbreviated Injury Scale/ região cabeça (MAIS/cabeça) apresentou média de 2,7 (dp=1,1). Entre a admissão na SE e 2 horas após, foram observadas mudanças desfavoráveis em 35,1% das vítimas e favoráveis em 27%; entre 2 e 4 horas, a evolução desfavorável foi constatada em 13,6% e favorável em 27,3%; entre 4 e 6 horas, constatou-se piora em 42,8% dos casos e melhora em 28,6%. Em média, as vítimas que tiveram piora apresentaram diferença de 2,8 (dp=2,3) no REMS entre admissão e 2 horas, de 2 (dp=0) entre 2 e 4 horas e de 2,3 (dp=0,5) entre 4 e 6 horas. Houve diferença estatisticamente significativa no tempo de permanência na SE somente em relação à variável uso de suporte hemodinâmico nesse serviço. Conclusão: A melhora de cerca de mais de » das vítimas de TCE contuso ocorreu em todos os períodos de avaliação, porém a frequência dos casos de evolução desfavorável foi maior do que favorável entre admissão e 2 horas e ainda mais elevada após permanência de 4 horas na SE. O maior tempo de permanência na SE esteve relacionado com uso de suporte hemodinâmico nesse serviço.

Introduction: The frequency of traumatic brain injury (TBI) in emergency services is increasing worldwide and knowing the evolution of these victims in the first hours after injury is an important way to standardize their evaluation and achieve better treatment outcomes. Objectives: To analyze the evolution of the victims whose main lesion was blunt TBI and to identify, among demographic variables, severity indicators and characteristics of pre and in-hospital care, as well as factors associated with length of stay in the emergency room (ER) of these victims. Method: A prospective study, with data collected at the admission of the TBI victim at ER and 2, 4 and 6 hours after, or until transfer to definitive treatment in specific units, or death. Participants of this study presented blunt TBI as the main lesion, age 15 years and were admitted at ER for neurosurgery up to 1 hour after trauma. The evolution of the victims was described by the differences in the Rapid Emergency Medicine Score (REMS) among the assessments on admission at ER and 2, 4 and 6 hours after. Descriptive analyzes were used to characterize the cases and describe the evolution of the victims. Statistical tests were applied to verify the association between length of stay in ER and age, sex, severity and characteristics of pre and in-hospital care. Results: The casuistry consisted of 46 victims, 84.7% were male, mean age was 34.7 years (SD=15.1), and 63% were involved in traffic accidents. On admission at ER, the mean REMS of these victims was 4.0 (SD=2.5), the mean Injury Severity Score (ISS) and New Injury Severity Score (NISS) were 11.8 (SD=7.7) and 17.2 (SD=12.7), respectively. Glasgow Coma Scale (GCS) indicated 54.4% of cases of severe TBI and the Maximum Abbreviated Injury Score/ head region (MAIS/head) showed an average of 2.7 (SD=1.1). From admission at ER until 2 hours later, unfavorable changes were observed in 35.1% of the victims and favorable changes were seen in 27%; between 2 and 4 hours, the unfavorable evolution was observed in 13.6% and favorable evolution was noted in 27.3%; between 4 and 6 hours, it was found worsening in 42.8% of the cases and improvement in 28.6%. On average, patients who experienced worsening had a difference of 2.8 (SD=2.3) in REMS from admission to 2 hours, 2 (SD=0) between 2 and 4 hours and 2.3 (SD=0.5) between 4 and 6 hours. There was a statistically significant difference in the lenght of stay in ER only in relation to the variable use of hemodynamic support in this service. Conclusion: The improvement of more than » of the victims of blunt TBI occurred in all the evaluation periods, but the frequency of unfavorable cases was higher than favorable between admission and 2 hours and even higher after 4 hours in ER. The longer time in ER was related to the use of hemodynamic support in this service.

Computed tomography of the head for adult patients with minor head injury: are clinical decision rules a necessary evil?

<p><b>INTRODUCTION</b>This study aimed to evaluate compliance with and performance of the Canadian Computed Tomography Head Rule (CCHR), and its applicability to the Singapore adult population with minor head injury.</p><p><b>METHODS</b>We conducted a retrospective study over six months of consecutive patients who presented to the adult emergency department (ED) with minor head injury. Data on predictor variables indicated in the CCHR was collected and compliance with the CCHR was assessed by comparing the recommendations for head computed tomography (CT) to its actual usage.</p><p><b>RESULTS</b>In total, 349 patients satisfied the inclusion criteria. Common mechanisms of injury were falls (59.3%), motor vehicle crashes (16.9%) and assault (12.0%). 249 (71.3%) patients underwent head CT, yielding 42 (12.0%) clinically significant findings. 1 (0.3%) patient required neurosurgical intervention. According to the CCHR, head CT was recommended for 209 (59.9%) patients. Compliance with the CCHR was 71.3%. Among the noncompliant group, head CT was overperformed for 20.1% and underperformed for 8.6% of patients. Multivariate logistic regression analysis revealed that absence of retrograde amnesia (odds ratio [OR] 4.1, 95% confidence interval [CI] 1.8-9.7) was associated with noncompliance to the CCHR. Factors associated with underperformance were absence of motor vehicle crashes as a mechanism of injury (OR 6.6, 95% CI 1.2-36.3) and absence of headache (OR 10.8, 95% CI 1.3-87.4).</p><p><b>CONCLUSION</b>Compliance with the CCHR for adult patients with minor head injury remains low in the ED.

Epidemiological pattern and outcome of head injuries during festive and non-festive periods in a tertiary hospital, Nnewi, Nigeria.

Background: Head injury is trauma to the brain and/or its coverings as a result of an externally applied mechanical force. Study of epidemiological pattern of head injuries is essential in developing necessary preventive strategies and control. To compare the prevalence and pattern of head injuries during the non-festive (February – September) and the festive (October – January) periods in our environment. Methods: Patients’ case files at the Accidents and Emergency unit of Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, were reviewed. Results: Two hundred and sixty-six out of 4,846 met the inclusion criteria for traumatic head injury and were recruited for the study, giving a prevalence of 5.5%. About 77.4% of these presentations were males while 22.6% were females. Both males and females were affected more in the festive period (52.4% and 48.3%) than in the non-festive period (51.7% and 47.6%). The >20 – 30 year group recorded the highest presentation at 30.5%. Traders and Commercial Motorcyclists were the most affected occupations with 25.9% and 24.1% respectively, with the most common causes of head injury during both the festive and non – periods being motorcycle and motor vehicle accidents (68% and 18% respectively). About 63% presented with mild head injury, 14% with moderate and 23% with severe head injuries. About 11.4% were discharged, 83.9% were transferred to the ward for further evaluation and monitoring while 4.7% died at the Accident and Emergency department. Conclusions: Traumatic head injury is one of the major causes of mortality and morbidity in our environment especially in the festive periods. Aggressive and sustained traffic safety education is recommended for all stakeholders in the broad field of accidentology.

Heridas por proyectil de arma de fuego en cráneo: revisión de la literatura / Firearm projectile wounds on skull: literature review

El trauma craneoencefálico es una de las principales causas de muerte en el mundo, y gran parte de estos se asocian a heridas por arma de fuego en cráneo.

Traumatic brain injury is a of the leading causes of death in the world, and many of these are associated with gunshot wounds in the skull. To know management the characteristics and pathophysiology of the lesion will tell as deal with these cases when presented to medical centers, while enabling us to take into account of possible complications, to prevent its occurrence and so try to improve morbidity from this cause. Always accompanied by an integrated management that can encompass all affected dimensions.

Traumatic arteriovenous fistula associated to pseudoaneurysm of the superficial temporal artery in a child: case report and literature review / Fístula arteriovenosa traumática associada a pseudoaneurisma da artéria temporal superficial em uma criança: relato de caso e revisão da literatura

As fístulas arteriovenosas (FAVs) e os pseudoaneurismas traumáticos extracranianos são malformações incomuns e, em sua maioria, estão associadas a traumatismo craniano fechado com lesão contusa de forte intensidade. O diagnóstico em geral é clínico, porém o exame de escolha para o diagnóstico definitivo é a angiografia. Nos casos em que a lesão é pequena, é possível abordá-la com embolização via endovascular com sucesso. A excisão cirúrgica, no entanto, ainda é o método de escolha para o tratamento. É relatado um caso de um paciente do sexo masculino, com 9 anos de idade, diagnosticado com FAV, acometendo o ramo frontal da artéria temporal superficial, secundária a trauma craniano contundente ocorrido três anos antes do diagnóstico.

The arteriovenous fistulae (AVFs) and the extracranial traumatic pseudoaneurysms are uncommon malformations and in the majority of the cases are associated to closed head trauma with high intensity blunt lesion. The diagnosis is generally clinical, though the exam of choice for definitive diagnosis is an angiography. In minor lesion cases it's possible to successfully approach it with endovas-cular embolization. The surgical excision though, is the method of choice for the treatment. Here is reported a case of a 9-year-old male patient, diagnosed with AVF involving the frontal branch of the superficial temporal artery, secondary to blunt head trauma occurred three years before diagnosis.

Lesiones penetrantes en el cerebro por cuerpos extraños intracraneales. Presentación de tres casos / Penetrating injuries in the brain by intracranial foreign bodies. Presentation of three cases

Fundamento: Las lesiones penetrantes cerebrales causadas por objetos extraños, incluidos proyectiles son comúnmente vistas en situaciones de guerra. Las lesiones no causadas por proyectiles son raras en la práctica neuroquirúrgica en la vida civil en tiempo de paz. Objetivo: Ilustrar formas clínicas y la evaluación de lesiones penetrantes del cerebro no causadas por municiones de armas de fuego en tiempo de paz, a través de la presentación de tres casos. Presentación de casos: Presentamos tres pacientes con cuerpos extraños intracraneales, el primero que durante intento suicida se introdujo a través de agujero de trépano objeto metálico (alambre de cobre); el segundo caso, paciente que al sufrir trauma de cráneo se le realizó tomografía axial computarizada de cráneo y se detectó la presencia de hematoma subdural agudo y cuerpo extraño intracraneal (pedazo de alambre); el tercer caso se trata de recluso que durante una riña sufrió herida con penetración de un cuerpo extraño intracraneal (clavo). Conclusiones: La intervención quirúrgica de estos pacientes de manera urgente y su estado neurológico al entrar al quirófano repercutió de manera decisiva en su evolución.

Background: Penetrating brain injuries due to foreign objects including gunshot wounds are commonly seen in war times. Injuries not caused by gunshot are rare in neurosurgical practice in civil lifetime in peace times. Objective: To illustrate the clinical forms and the evaluation of penetrating brain injuries not caused by ammunitions of firearms in peacetime, through the presentation of three cases. Cases presentation: We report three patients with intracranial foreign bodies, the first during suicide attempt was introduced via burr hole metal object (copper wire); the second case, the patient suffered head injury and underwent computed tomography of the skull and the presence of acute subdural hematoma and intracranial foreign body (piece of wire) was detected; the third case involves prisoner who suffered injury during a fight with intracranial penetration of a foreign body (nail). Conclusions: Urgently surgical intervention in these patients and their neurological status entering the operating room impacted decisively in their evolution.

Three years with a knife stuck in the brain / Três anos com uma faca cravada no encéfalo

Cranial stabbing injuries penetrating the brain are not commonly encountered. The cases in which the knife is retained constitute a challenge to the neurosurgeon. When a long-term permanence occurs, the reaction to the presence of the foreign body causes adherence to the nervous tissue and a higher risk is expected from the removal. The procedure should be performed with meticulous dissection and minimal oscillation of the blade thus avoiding damage to the adjacent structures. We report a case of a man who remained three years with a knife blade deeply lodged in the brain. After obtaining informed consent, the blade was removed; there were no postoperative complications. To our knowledge, this is the first case in which, after years of permanence, a knife blade was removed from the brain through a craniotomy.

Lesões cranianas por arma branca com penetração do encéfalo não são comuns. Os casos em que a faca encontra-se retida constituem um desafio para o neurocirurgião. Quando ocorre uma longa permanência, a reação à presença do corpo estranho causa aderência ao tecido nervoso e um maior risco é previsto para a remoção. O procedimento deve ser realizado com dissecção meticulosa e mínima oscilação da lâmina, evitando, assim, lesão das estruturas adjacentes. Apresentamos o caso de um indivíduo que permaneceu três anos com a lâmina de uma faca alojada profundamente no encéfalo. Após obtermos consentimento informado, a lâmina foi removida; não houve complicações pós-operatórias. Até onde sabemos, este é o primeiro caso em que, após anos de permanência, a lâmina de uma faca foi removida do encéfalo por meio de uma craniotomia.

Study of pattern of fatal head injury cases due to road traffic accidents in Bhavnagar Region, Gujarat.

Introduction: Head injury is an important cause of mortality world wide as head is the most vulnerable part of the body involved in fatal road traffic accident. Material and Methods: The present study was under taken on 117 victims of road traffic accident who died due to injuries sustained on the head, which were autopsied at mortuary complex of Government Medical College and Sir Takhtsinhji General Hospital, Bhavnagar, Gujarat over a period of 1 year between 1st January 2011 to 31st December 2011. Observation: Most of the road traffic accident had taken place in the afternoon hours (12.01 P.M. to 6.00 P.M.).Majority of victims were found in age group of 21 to 30 years. Two wheeler occupants were the most commonly involved. Four wheeler occupants and pedestrians were least commonly involved. A large proportion of the victims died within 0 to 12 hours of the accident. Conclusion: Very high morbidity at place of accident or at initial phase of treatment is definitely alarming and highlights the need for taking urgent steps for establishing good pre-hospital care and provision of trauma services at site.

Visualization of a Traumatic Pseudoaneurysm at Internal Carotid Artery Bifurcation due to Blunt Head Injury: A Case Report / 대한신경손상학회지

Traumatic intracranial pseudoaneurysms occurring after blunt head injuries are rare. We report an unusual case of subarachnoid hemorrhage (SAH) caused by rupturing of the traumatic pseudoaneurysm of the internal carotid artery (ICA) bifurcation that resulted from a non-penetrating injury. In a patient with severe headache and SAH in the right sylvian cistern, which developed within 7 days after a blunt-force head injury, a trans-femoral cerebral angiogram (TFCA) showed aneurysmal sac which was insufficient to confirm the pseudoaneurysm. We obtained a multi-slab image of three dimensional time of flight (TOF) of magnetic resonance angiography (MRA). The source image of the gadolinium-enhanced MRA revealed an intimal flap within the intracranial ICA bifurcation, providing a clue for the diagnosis of a dissecting pseudoaneurysm at the ICA bifurcation due to blunt head trauma. We performed direct aneurysmal neck clipping, without neurological deficit. A follow-up TFCA did not show either aneurysm sac or luminal narrowing. We suggest that in the patient with a history of blunt head injury with SAH following shortly, multi-slab image of 3D TOF MRA can give visualization of the presence of a pseudoaneurysm.
