ABSTRACT
Primary decompressive craniectomy (DC) is carried out to prevent intracranial hypertension after removal of mass lesions resulting from traumatic brain injury (TBI). While primary DC can be a life-saving intervention, significant mortality risks persist during the follow-up period. This study was undertaken to investigate the long-term survival rate and ascertain the risk factors of mortality in TBI patients who underwent primary DC. We enrolled 162 head-injured patients undergoing primary DC in this retrospective study. The primary focus was on long-term mortality, which was monitored over a range of 12 to 209 months post-TBI. We compared the clinical parameters of survivors and non-survivors, and used a multivariate logistic regression model to adjust for independent risk factors of long-term mortality. For the TBI patients who survived the initial hospitalization period following surgery, the average duration of follow-up was 106.58 ± 65.45 months. The recorded long-term survival rate of all patients was 56.2% (91/162). Multivariate logistic regression analysis revealed that age (odds ratio, 95% confidence interval = 1.12, 1.07-1.18; p < 0.01) and the status of basal cisterns (absent versus normal; odds ratio, 95% confidence interval = 9.32, 2.05-42.40; p < 0.01) were the two independent risk factors linked to long-term mortality. In conclusion, this study indicated a survival rate of 56.2% for patients subjected to primary DC for TBI, with at least a one-year follow-up. Key risk factors associated with long-term mortality were advanced age and absent basal cisterns, critical considerations for developing effective TBI management strategies.

PURPOSE: Decompressive craniectomy is occasionally performed as a life-saving neurosurgical intervention in patients with acute severe brain injury to reduce refractory intracranial hypertension. Subsequently, cranioplasty (CP) is performed to repair the skull defect. In the meantime, patients are living without cranial bone protection, and little is known about their daily life. This study accordingly explored daily life among patients living without cranial bone protection after decompressive craniectomy while awaiting CP. METHODS: A multiple-case study examined six purposively sampled patients, patients' family members, and healthcare staff. The participants were interviewed and the data were analyzed using qualitative content analysis. RESULTS: The cross-case analysis identified five categories: "Adapting to new ways of living," "Constant awareness of the absence of cranial bone protection," "Managing daily life requires available staff with adequate qualifications," "Impact of daily life depends on the degree of recovery," and "Daily life stuck in limbo while awaiting cranioplasty." The patients living without cranial bone protection coped with daily life by developing new habits and routines, but the absence of cranial bone protection also entailed inconveniences and limitations, particularly among the patients with greater independence in their everyday living. Time spent awaiting CP was experienced as being in limbo, and uncertainty regarding planning was perceived as frustrating. CONCLUSION: The results indicate a vulnerable group of patients with brain damage and communication impairments struggling to find new routines during a waiting period experienced as being in limbo. Making this period safe and reducing some problems in daily life for those living without cranial bone protection calls for a person-centered approach to care involving providing contact information for the correct healthcare institution and individually planned scheduling for CP.

Neurological patients frequently have disorders of consciousness, swallowing disorders, or neurological states that are incompatible with extubation. Therefore, they frequently require tracheostomies during their stay in an intensive care unit. After the acute phase, tracheostomy weaning and decannulation are generally expected to promote rehabilitation. However, few reliable predictive factors (PFs) for decannulation have been identified in this patient population. We sought to identify PFs that may be used during tracheostomy weaning and decannulation in patients with brain injuries. We conducted a systematic review of the literature regarding potential PFs for decannulation; searches were performed on 16 March 2021 and 1 June 2022. The following databases were searched: MEDLINE, EMBASE, CINAHL, Scopus, Web of Science, PEDro, OPENGREY, OPENSIGLE, Science Direct, CLINICAL TRIALS and CENTRAL. We searched for all article types, except systematic reviews, meta-analyses, abstracts, and position articles. Retrieved articles were published in English or French, with no date restriction. In total, 1433 articles were identified; 26 of these were eligible for inclusion in the review. PFs for successful decannulation in patients with acquired brain injuries (ABIs) included high neurological status, traumatic brain injuries rather than stroke or anoxic brain lesions, younger age, effective swallowing, an effective cough, and the absence of pulmonary infections. Secondary PFs included early tracheostomy, supratentorial lesions, the absence of critical illness polyneuropathy/myopathy, and the absence of tracheal lesions. To our knowledge, this is the first systematic review to identify PFs for decannulation in patients with ABIs. These PFs may be used by clinicians during tracheostomy weaning.

The period begins with the work of Richard Wiseman who was associated with royalists in the English Civil War. A little later Dionis was the first to note a relationship between a disturbance of consciousness and extravasation of blood. This notion was continued and expanded by Le Dran, Pott, and Benjamin Bell, with Pott providing a pathophysiological explanation of the phenomenon. Daniel Turner commented on how confusing Galenic teaching was on the topic of consciousness. Heister further emphasized the relationship between clinical disturbance and the extravasation of blood. Le Dran stated that symptoms following cranial trauma related to cerebral injury, an opinion supported by Pott and never subsequently challenged. Latta noted the importance of meningeal arteries in the development of hematomas. Benjamin Bell considered trepanation only appropriate for a clinical deterioration consistent with hemorrhagic extravasation. The two Irish surgeons made it clear that the presence of periosteal separation was not in fact a reliable indicator of an extravasation. The most striking change of instruments was disappearance of simple straight trepans with non-perforating tips for making small holes safely. The use of scrapers gradually declined as did that of lenticulars. There was a great debate about the value of a conical rather than a cylindrical crown. The former was said to be safer. But this opinion faded and the cylindrical crown became preferred. Another improvement in technique involved the use of constant probing to check the depth of the drilled groove.

BACKGROUND: Early operative intervention, craniotomy, and/or craniectomy are occasionally warranted in severe traumatic brain injury (TBI). Persistent increased intracranial pressure or accumulation of intracranial hematoma postsurgery can result in higher mortality and morbidity. There is a gap in information regarding the outcome of repeat surgery (RS) in pediatric patients with severe TBI. METHODS: An observational cohort study titled Approaches and Decisions in Acute Pediatric TBI Trial data was obtained from the Federal Interagency Traumatic Brain Injury Research Informatics System. All pediatric patients who underwent craniotomy or decompressive craniectomy, survived more than 44 hours and were found to have persistent elevated intracranial pressure >20 mmHg for 2 consecutive hours were included in the study. The purpose of the study was to find the outcomes of RS in pediatric severe TBI. Propensity based matching was used to find the outcomes. The primary outcome was 60-day mortality. RESULTS: Out of 1000 total patients enrolled in the Approaches and Decisions in Acute Pediatric Trial, 160 patients qualified for this study. Propensity score matching created 13 pairs of patients. There were no significant differences found between the groups who had RS versus those who did not have repeat surgery on baseline characteristics. There were no significant differences found between the groups regarding 60-day mortality, median hospital days, median intensive care unit days, and 6-month favorable outcome on Glasgow Outcome Scale Extended score. CONCLUSIONS: There was no difference in mortality between patients who underwent a second surgery and patients who did not have to undergo a second surgery.

Craniotomy or decompressive craniectomy are among the therapeutic options to prevent or treat secondary damage after severe brain injury. The choice of procedure depends, among other things, on the type and severity of the initial injury. It remains controversial whether both procedures influence the neurological outcome differently. Thus, estimating the risk of brain herniation and death and consequently potential organ donation remains difficult. All patients at the University Hospital Münster for whom an isolated craniotomy or decompressive craniectomy was performed as a treatment after severe brain injury between 2013 and 2022 were retrospectively included. Proportion of survivors and deceased were evaluated. Deceased were further analyzed regarding anticoagulants, comorbidities, type of brain injury, potential and utilized donation after brain death. 595 patients were identified, 296 patients survived, and 299 deceased. Proportion of decompressive craniectomy was higher than craniotomy in survivors (89% vs. 11%, p < 0.001). Brain death was diagnosed in 12 deceased and 10 donations were utilized. Utilized donations were comparable after both procedures (5% vs. 2%, p = 0.194). Preserved brain stem reflexes as a reason against donation did not differ between decompressive craniectomy or craniotomy (32% vs. 29%, p = 0.470). Patients with severe brain injury were more likely to survive after decompressive craniectomy than craniotomy. Among the deceased, potential and utilized donations did not differ between both procedures. This suggests that brain death can occur independent of the previous neurosurgical procedure and that organ donation should always be considered in end-of-life decisions for patients with a fatal prognosis.

Postoperative neurological dysfunction (PND) is one of the most common complications after a total aortic arch replacement (TAAR). Electrical impedance tomography (EIT) monitoring of cerebral hypoxia injury during TAAR is a promising technique for preventing the occurrence of PND. This study aimed to explore the feasibility of electrical impedance tomography (EIT) for warning of potential brain injury during total aortic arch replacement (TAAR) through building the correlation between EIT extracted parameters and variation of neurological biomarkers in serum. Patients with Stanford type A aortic dissection and requiring TAAR who were admitted between December 2021 to March 2022 were included. A 16-electrode EIT system was adopted to monitor each patient's cerebral impedance intraoperatively. Five parameters of EIT signals regarding to the hypothermic circulatory arrest (HCA) period were extracted. Meanwhile, concentration of four neurological biomarkers in serum were measured regarding to time before and right after surgery, 12 h, 24 h and 48 h after surgery. The correlation between EIT parameters and variation of serum biomarkers were analyzed. A total of 57 TAAR patients were recruited. The correlation between EIT parameters and variation of biomarkers were stronger for patients with postoperative neurological dysfunction (PND(+)) than those without postoperative neurological dysfunction (PND(-)) in general. Particularly, variation of S100B after surgery had significantly moderate correlation with two parameters regarding to the difference of impedance between left and right brain which were MRAIabs and TRAIabs (0.500 and 0.485 with p < 0.05, respectively). In addition, significantly strong correlations were seen between variation of S100B at 24 h and the difference of average resistivity value before and after HCA phase (ΔARVHCA), the slope of electrical impedance during HCA (kHCA) and MRAIabs (0.758, 0.758 and 0.743 with p < 0.05, respectively) for patients with abnormal S100B level before surgery. Strong correlations were seen between variation of TAU after surgery and ΔARVHCA, kHCA and the time integral of electrical impedance for half flow of perfusion (TARVHP) (0.770, 0.794 and 0.818 with p < 0.01, respectively) for patients with abnormal TAU level before surgery. Another two significantly moderate correlations were found between TRAIabs and variation of GFAP at 12 h and 24 h (0.521 and 0.521 with p < 0.05, respectively) for patients with a normal GFAP serum level before surgery. The correlations between EIT parameters and serum level of neurological biomarkers were significant in patients with PND, especially for MRAIabs and TRAIabs, indicating that EIT may become a powerful assistant for providing a real-time warning of brain injury during TAAR from physiological perspective and useful guidance for intensive care units.

BACKGROUND: Decompressive craniectomy (DC) is a surgical procedure to treat refractory increase in intracranial pressure. DC is frequently succeeded by cranioplasty (CP), a reconstructive procedure to protect the underlying brain and maintain cerebrospinal fluid flow dynamics. However, complications such as seizures, fluid collections, infections, and hydrocephalus can arise from CP. Our aim is to investigate these complications and their possible risk factors and to discuss whether early or late CP has any effect on the outcome. MATERIALS AND METHODS: A single-center retrospective cohort study was performed, including patients who underwent CP after DC between January 2014 and January 2022. Relevant information was collected such as demographics, type of brain injury, materials used in CP, timing between DC and CP, and postoperative complications. Ultimately, 63 patients were included in our study. We also compared the complication rate between patients who underwent late CP after DC (>90 days) against patients who underwent early CP (<90 days). RESULTS: Most patients were male (78%). The sample median age was 29 years, with pediatric patients, accounting for 36% of the samples. Overall complication rate was 57% and they were seizure/epilepsy in 50% of the patients, fluid collection (28%), infections (25%), posttraumatic hydrocephalus (17%), and bone defect/resorption (3%). Twenty-two percent of patients with complications required reoperation and underwent a second CP. The median (interquartile range) duration between the craniotomy and the CP was 56 (27-102) days, with an early (≤3 months) percentage of 68%. We found no significant difference between early (≤3 months) and late (>3 months) CP regarding complication rates. CONCLUSION: Despite CP being a simple procedure, it has a considerable rate of complications. Therefore, it is important that surgeons possess adequate knowledge about such complications to navigate these challenges more effectively.
Résumé Contexte:La craniectomie décompressive (DC) est une intervention chirurgicale destinée à traiter l'augmentation réfractaire de la pression intracrânienne. La DC est fréquemment remplacée par une cranioplastie (CP), une procédure reconstructive visant à protéger le cerveau sous-jacent et à maintenir la dynamique du flux du liquide céphalo-rachidien. Cependant, des complications telles que des convulsions, des collections de liquides, des infections et une hydrocéphalie peuvent survenir en raison de la CP. Notre objectif est d'étudier ces complications et leurs facteurs de risque possibles et de discuter si une CP précoce ou tardive a un effet sur le résultat.Matériels et méthodes:Une étude de cohorte rétrospective monocentrique a été réalisée, incluant des patients ayant subi une PC après une DC entre janvier 2014 et janvier 2022. Des informations pertinentes ont été collectées telles que les données démographiques, le type de lésion cérébrale, les matériaux utilisés dans la PC, le timing entre la DC et CP et complications postopératoires. Au final, 63 patients ont été inclus dans notre étude. Nous avons également comparé le taux de complications entre les patients ayant subi une CP tardive après une DC (> 90 jours) et ceux ayant subi une CP précoce (<90 jours).Résultats:La plupart des patients étaient des hommes (78 %). L'âge médian de l'échantillon était de 29 ans, les patients pédiatriques représentant 36 % des échantillons. Le taux global de complications était de 57 % et il s'agissait de convulsions/épilepsie chez 50 % des patients, d'accumulation de liquide (28 %), d'infections (25 %), d'hydrocéphalie post-traumatique (17 %) et de défauts/résorptions osseuses (3 %). Vingtdeux pour cent des patients présentant des complications ont dû être réopérés et ont subi une deuxième CP. La durée médiane (intervalle interquartile) entre la craniotomie et la CP était de 56 (27 à 102) jours, avec un pourcentage précoce (≤ 3 mois) de 68 %. Nous n'avons trouvé aucune différence significative entre la PC précoce (≤ 3 mois) et tardive (> 3 mois) en ce qui concerne les taux de complications.Conclusion:Bien que la CP soit une procédure simple, elle entraîne un taux de complications considérable. Il est donc important que les chirurgiens possèdent des connaissances adéquates sur ces complications pour relever ces défis plus efficacement.

ABSTRACT PURPOSE: To compared the effects of sevoflurane and desflurane on early anesthesia recovery in patients undergoing to craniotomy for intracranial lesions. METHODS: After IRB approval, the study included 50 patients aged 18-70 years who had ASA physical statuses of I-II and were scheduled for intracranial surgery. Patients were randomly divided into two groups: sevoflurane and desflurane. Anaesthesia was routinely induced in all patients followed by desflurane 5%-6% or sevoflurane 1%-2%. Moreover remifentanil infusion (0.05-0.2 mcg/kg/min) was adjusted to maintain mean arterial pressure (MAP) within 20% baseline and heart rate <90 bpm. Postoperatively, patients were evaluated over time for responses to painful stimulus, eye opening, hand squeezing, extubation, orientation and time required to achieve a Modified Aldrete Score of 9-10. Parametric and non-parametric data were assessed using Student's t- and Mann-Whitney U tests, respectively. A p<0.05 was taken as statistically significant. RESULTS: The times to responses to painful stimuli (7.7±2.7 vs. 4.8±1.7 min.; p<0.001), emergence (9.5±2.81 vs. 6.3±2.2 min.; p<0.001), hand-squeezing (12.1±2.9 vs. 8.2±2.3 min.; p<0.001), extubation (10.1±2.87 vs. 7.1±1.6 min.; p<0.001), orientation (15.3±3.2 vs. 10.3±2.7 min.; p<0.001) and Aldrete score of 9-10 (23.3±6.1 vs. 15.8±3.8 min.; p<0.001) were significantly lower with desflurane-based anaesthesia vs. sevoflurane-based anaesthesia. CONCLUSION: Desflurane yields early recovery functions and facilitates early postoperative neurologic examinations of intracranial surgery patients.

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 ...

Decompressive craniectomy (DC) is widely used to treat intracranial hypertension following traumatic brain injury (TBI) or cerebral vascular disease. Many studies have discussed complications of this procedure, and hydrocephalus is a common complication of DC. To further evaluate the relationship between DC and hydrocephalus, a review of the literature was performed. Numerous complications may arise after DC, including contusion or hematoma expansion, epilepsy, herniation of the cortex through a bone defect, CSF leakage through the scalp incision, infection, subdural effusion, hydrocephalus and “syndrome of the trephined”. Several hydrocephalus predictors were identified; these included DC, distance from the midline, hygroma, age, injury severity, subarachnoid or intraventricular hemorrhage, delayed time to craniotomy, repeated operation, and duraplasity. However, results differed among studies. The impact of DC on hydrocephalus remains controversial.
A craniectomia descompressiva (CD) é amplamente utilizada para tratar a hipertensão intracraniana após trauma craniencefálico (TC) ou doença cerebrovascular. Vários estudos discutem as complicações deste procedimento, sendo a hidrocefalia uma das complicações mais frequentes. Fizemos uma revisão da literatura para avaliar a relação entre a CD e a hidrocefalia. Podem ocorrer numerosas complicações após a CD, incluindo aumento de volume por contusão ou hematoma, epilepsia e herniação do cortex cerebral através do acesso ósseo. Fístulas liquóricas através a incisão no couro cabeludo, infecções, hematomas subdurais, hidrocefalia e a “síndrome pós-trepanação”. Foram identificados vários fatores preditivos de hidrocefalia: a distância da CD em relação à linha média, a ocorrência de higroma, a idade, a gravidade da lesão, a hemorragia subaracnóidea ou intraventricular, o tempo decorrido até a craniectomia, as reoperações e o uso de plástica com dura-máter. Entretanto, há divergências entre os autores e o impacto da CD na hidrocefalia continua controvertido.

OBJETIVO: Comparar os efeitos da traqueostomia precoce e da traqueostomia tardia em pacientes com lesão cerebral aguda grave. MÉTODOS: Estudo retrospectivo com 28 pacientes admitidos na UTI do Hospital Universitário da Universidade Federal de Juiz de Fora com diagnóstico de lesão cerebral aguda grave e apresentando escore na escala de coma de Glasgow (ECG) < 8 nas primeiras 48 h de internação. Os pacientes foram divididos em dois grupos: traqueostomia precoce (TP), realizada em até 8 dias; e traqueostomia tardia (TT), realizada após 8 dias. Dados demográficos e os escores Acute Physiology and Chronic Health Evaluation (APACHE) II, ECG e Sequential Organ Failure Assessment (SOFA) do dia da admissão foram coletados. RESULTADOS: Não houve diferenças significativas em relação aos dados demográficos ou aos escores coletados nos grupos TP e TT: APACHE II (26 ± 6 vs. 28 ± 8; p = 0,37), SOFA (6,3 ± 2,7 vs. 7,2 ± 3,0; p = 0,43) e ECG (5,4 ± 1,7 vs. 5,5 ± 1,7; p = 0,87). A mortalidade em 28 dias foi menor no grupo TP (9 por cento vs. 47 por cento; p = 0,04). Pneumonia nosocomial precoce (até 7 dias) foi menos frequente no grupo TP, mas essa diferença não foi significativa (0 por cento vs. 23 por cento, p = 0,13). Não houve diferenças em relação à ocorrência de pneumonia tardia ou ao tempo de ventilação mecânica entre os grupos. CONCLUSÕES: Baseado nesses achados, a traqueostomia precoce deve ser considerada em pacientes com lesão cerebral aguda grave.
OBJECTIVE: To compare the effects of early tracheostomy and of late tracheostomy in patients with acute severe brain injury. METHODS: A retrospective study involving 28 patients admitted to the ICU of the Federal University of Juiz de Fora University Hospital in Juiz de Fora, Brazil, diagnosed with acute severe brain injury and presenting with a Glasgow coma scale (GCS) score < 8 within the first 48 h of hospitalization. The patients were divided into two groups: early tracheostomy (ET), performed within the first 8 days after admission; and late tracheostomy (LT), performed after postadmission day 8. At admission, we collected demographic data and determined the following scores: Acute Physiology and Chronic Health Evaluation (APACHE) II, GCS and Sequential Organ Failure Assessment (SOFA). RESULTS: There were no significant differences between the groups (ET vs. LT) regarding the demographic data or the scores: APACHE II (26 ± 6 vs. 28 ± 8; p = 0.37), SOFA (6.3 ± 2.7 vs. 7.2 ± 3.0; p = 0.43) and GCS (5.4 ± 1.7 vs. 5.5 ± 1.7; p = 0.87). The 28-day mortality rate was lower in the ET group (9 percent vs. 47 percent; p = 0.04). Nosocomial pneumonia occurring within the first 7 days was less common in the ET group, although the difference was not significant (0 percent vs. 23 percent; p = 0.13). There were no differences regarding the occurrence of late pneumonia or in the duration of mechanical ventilation between the groups. CONCLUSIONS: On the basis of these findings, early tracheostomy should be considered in patients with acute severe brain injury.

INTRODUÇÃO: A indicação do tratamento cirúrgico das lesões parenquimatosas temporais de origem traumática é controversa. Analisaram-se os parâmetros tomográficos que poderiam ser úteis nesta decisão terapêutica. MÉTODO: Os achados tomográficos de 69 patientes foram analisados retrospectivamente em relação a: 1) efeitos das lesões (classificados em 4 variáveis: desvio de estruturas medianas, estado das cisternas, dos ventrículos e dos sulcos periféricos); e 2) características das lesões: localização anterior, posterior ou ântero-posterior (definida por um plano coronal tangente aos pedúnculos cerebrais) e diâmetro médio-lateral. RESULTADOS: Quando nenhuma ou uma das variáveis acima mencionadas foi encontrada alterada, foi instituído o tratamento conservador (22 em 38 lesões). Em dois casos, as quatro variáveis estavam alteradas, sendo instituído o tratamento cirúrgico. Lesões anteriores, ântero-posteriores e posteriores medindo 21, 23 e 28 mm, respectivamente, tiveram 50% de chance de serem removidas. CONCLUSÃO: Nos casos operados, quanto mais anterior a lesão esteve no lobo temporal, menor foi seu diâmetro.

Considerando o estado neurológico imediatamente antes da operaçäo como a variável mais fidedigna para antecipaçäo do prognóstico do hematomas extradural, os autores realizaram estudo radiológico comparativo de 129 pacientes operados por esta patologia. Desta amostra, 78 casos se encontravam em coma (Grupo 1) e 31 eram näo comatosos (Grupo II). No grupo I, os 30 casos investigados pré-operatoriamente com tomografia tiveram 23,3// de mortalidade e 50// de bons resultados; dos 31 casos submetidos a angiografia, 48,3// faleceram e 38,7// tiveram bons resultados; 17 casos foram operados pela radiografia simples de crânio e exame neurológico, com 47// de mortalidade e 35,2// de bons resultados. A presença de fratura de crânio e a densidade tomográfica do hematoma näo interferiram nos resultados. A presença de lesäo associada intracraniana aumentou a mortalidade e diminuiu a quantidade de bons resultados tanto no Grupo I quanto no Grupo II. A localizaçäo frontal do hematoma foi associada a elevada mortalidade (52,6// no grupo comatoso, por estarem todos os pacientes entre 3 a 5 pontos na Escala de Glasgow e seis deles por apresentarem lesöes associadas intracranianas únicas ou múltiplas

O Serviço de Neurocirurgia de Urgência do Pronto Socorro do Hospital das Clínicas da Faculdade de Medicina da USP (FMUSP) recebeu e tratou 19 crianças, com idade igual ou inferior a 15 anos, vítimas de ferimento craniencefálico por projétil de arma de fogo, no período de 1980 a 1990. A mortalidade nos pacientes operados foi de 35,3 por cento e a mortalidade geral de 42,1 por cento. Além da gravidade da lesao, condiçoes relacionadas ao atendimento pré-hospitalar e ao suporte pós-opertário contribuíram, de maneira significativa, para elevados índices de morbidade e mortalidade. Säo analisados os fatores implicados no prognóstico e säo propostas terapêuticas que presupöem medidas de suporte pré e pós-operatórias e cirurgias pouco agressivas.
