ABSTRACT

ABSTRACT The New Coronavirus Epidemic (2019-nCoV), discovered in the city of Wuhan, China, in December 2019, presents mainly with pulmonary pneumonia that is preceded by fever, cough and myalgia. However, as the disease spread globally and the number of hospitalizations increased exponentially, it was noted that most serious patients hospitalized by COVID-19 have laboratory changes worthy of attention, such as lymphopenia, neutrophilia, increased time of prothrombin and increased levels of D-dimer. Due to these changes proving to be crucial for the mortality and morbidity rates in this subset of infected people, several studies focusing on the pathophysiology, mainly hematological, of the disease appear every day. Deepening these studies, several published works have shown SarsCoV-2 infection to the installation of a prothrombotic state in hospitalized patients, which leads to the potential occurrence of thrombotic or arterial events in this cohort. Thus, in order to understand how the departments of Angiology and Vascular Surgery are acting in the context of the COVID-19 pandemic, this work aims to gather studies that reveal from protocols applied in vascular services in the current situation, until to the role of vascular surgeons and angiologists in the clinical and surgical management of patients infected or not, as a way of helping and clarifying this specialty during the context of a pandemic due to the new coranavirus. For the selection of works, the following search criteria were used: "Coronavirus and venous thrombosis", "Coronavirus and thrombosis", "COVID-19 and venous thrombosis" and "COVID-19 Coronavirus and thrombosis".


RESUMO A epidemia pelo novo Coronavirus (2019-nCoV), surgido na cidade de Wuhan, na China, em dezembro de 2019, quando sintomática, apresenta-se majoritariamente por um quadro de pneumonia pulmonar que é precedida por febre, tosse seca e mialgia. No entanto, conforme a doença se espalhou globalmente e o número de hospitalizações aumentaram de forma exponencial, notou-se que a maior parte dos pacientes graves internados por COVID-19 possuem alterações laboratoriais dignas de atenção, como linfopenia, neutrofilia, aumento do tempo de protrombina e elevação dos níveis de D-dímero. Devido tais mudanças se mostrarem cruciais para a taxa de mortalidade e morbidade nesse subgrupo de infectados, diversos trabalhos com enfoque na fisiopatologia, principalmente hematológica, da doença surgem a cada dia. Aprofundando em tais estudos, variados trabalhos publicados evidenciaram a infecção pelo Sars-CoV-2 à instalação de um estado pró-trombótico em pacientes hospitalizados graves, o que acarreta em potencial ocorrência de eventos trombóticos venosos ou arteriais nessa coorte. Assim, para entender como os Departamentos de Angiologia e Cirurgia Vascular estão atuando no contexto da pandemia de COVID-19, este estudo tem por objetivo reunir estudos que revelam desde protocolos aplicados nos serviços vasculares na atual conjuntura, até a atuação dos cirurgiões vasculares e angiologistas no manejo clínico e cirúrgico de pacientes infectados ou não, como forma de ajudar e esclarecer essa especialidade durante o contexto de pandemia pelo novo coronavírus. Para a seleção dos trabalhos foram utilizados os seguintes critérios de busca: "Coronavirus and venous thrombosis", "Coronavirus and thrombosis", "COVID-19 and venous thrombosis" e "COVID-19 Coronavirus and thrombosis".

ABSTRACT

ABSTRACT Background: Hepatic artery thrombosis is an important cause of graft loss and ischemic biliary complications. The risk factors have been related to technical aspects of arterial anastomosis and non-surgical ones. Aim: To evaluate the risk factors for the development of hepatic artery thrombosis. Methods: The sample consisted of 1050 cases of liver transplant. A retrospective and cross-sectional study was carried out, and the variables studied in both donor and recipient. Results: Univariate analysis indicated that the variables related to hepatic artery thrombosis are: MELD (p=0.04) and warm time ischemia (p=0.005). In the multivariate analysis MELD=14.5 and warm ischemia time =35 min were independent risk factors for hepatic artery thrombosis. In the prevalence ratio test for analysis of the anastomosis as a variable, it was observed that patients with continuous suture had an increase in thrombosis when compared to interrupted suture. Conclusions: Prolonged warm ischemia time, calculated MELD and recipient age were independent risk factors for hepatic artery thrombosis after liver transplantation in adults. Transplanted patients with continuous suture had an increase in thrombosis when compared to interrupted suture. Re-transplantation due to hepatic artery thrombosis was associated with higher recipient mortality.


RESUMO Racional: Trombose de artéria hepática é importante causa de falência de enxerto e complicações biliares. Fatores de risco para trombose estão relacionados aos aspectos técnicos da anastomose arterial e fatores não cirúrgicos. Objetivo: Avaliar os fatores de risco para o desenvolvimento de trombose de artéria hepática. Métodos: A amostra consta de 1050 casos de transplante hepático. Foi realizado estudo retrospectivo e transversal, e as variáveis foram avaliadas em doadores e receptores. Resultados: A análise univariada mostrou que as variáveis relacionadas a trombose de artéria hepática são: MELD e tempo de isquemia quente. Na análise multivariada, o MELD=14.5 e tempo de isquemia quente =35 min foram fatores de risco independentes para trombose de artéria hepática. No teste de prevalência para avaliação do tipo de anastomose como variável, foi observado que a sutura contínua tem maior risco de trombose quando comparada com aquela em pontos separados. Conclusão: Tempo de isquemia quente prolongado, MELD calculado e idade do recipiente foram fatores de risco independentes para trombose de artéria hepática após transplante de fígado em adultos. Pacientes submetidos à anastomose com sutura contínua apresentaram mais trombose quando comparados com a em pontos separados. Retransplante por trombose está associado com maior mortalidade.

ABSTRACT

Resumen La migraña afecta a un porcentaje importante de la población y los síntomas pueden interferir con calidad de vida de manera importante. A pesar de los avances en el manejo médico, existe una proporción de pacientes que no responden adecuadamente a la intervención farmacológica. En los últimos años, se han planteado nuevos enfoques en el tratamiento de la migraña. Éstos se basan en la teoría que ramas sensoriales extracraneales del trigémino y de los nervios espinales cervicales pueden irritarse, atraparse o comprimirse en algún punto a lo largo de su trayecto, generándose una cascada de eventos fisiológicos que finalmente resulta en la migraña. Se ha demostrado que la inyección diagnóstica y terapéutica de toxina botulínica y la descompresión quirúrgica de estos puntos gatillos reducen o eliminan las migrañas en pacientes que no responden adecuadamente a la intervención farmacológica y siguen sintomáticos. La evidencia que respalda la eficacia y seguridad de la descompresión quirúrgica de los puntos de gatillos periféricos se está acumulando rápidamente, y la tasa de éxito general de la cirugía se acerca a 90%. Este trabajo revisa la evidencia clínica y pretende proporcionar un artículo sobre el estado actual de la técnica en el tratamiento quirúrgico de las migrañas.


Migraine headaches affect a significant percentage of the population and the symptoms can interfere with quality of life in an important way. Despite advances in medical management, there is a proportion of patients who do not respond adequately to the pharmacological intervention. In recent years, new approaches have been proposed in the treatment of migraine. These are based on the theory that extracranial sensory branches of the trigeminal and cervical spinal nerves can become irritated, trapped or compressed at some point along their path, generating a cascade of physiological events that ultimately results in migraine. It has been shown that the diagnostic and therapeutic injection of botulinum toxin and the surgical decompression of these trigger points reduce or eliminate migraines in patients who do not respond adequately to the pharmacological intervention and remain symptomatic. The evidence supporting the efficacy and safety of surgical decompression of peripheral trigger points is rapidly accumulating, and the overall success rate of surgery approaches 90%. This paper reviews the clinical evidence and aims to provide an article on the current state of the art in the surgical treatment of migraines.

ABSTRACT

Abstract Objective: This study aimed to evaluate the early operative outcomes and to compare the left ventricle and mitral valve functions after initial Takeuchi repair in patients with anomalous left coronary arising from pulmonary artery (ALCAPA). Methods: Fourteen patients (5 males, 9 females; mean age 4.3 years, ranging from 25 days to 34 years) who were operated for ALCAPA between 2007 and 2018 were included in this study. Data were evaluated retrospectively based on our medical records. Results: Hospital mortality rate was 7.1% (n=1). Thirteen surviving patients were kept in follow-up mean 4.3±3.05 years. When compared to preoperative measurements, both left ventricular ejection fraction (LVEF), (P=0.007) and mitral regurgitation (MR) (P=0.001) significantly improved before discharge. Moreover, LVEF values were improved in the late follow-up, considering early postoperative outcomes, and this alteration was significant (P=0.014). Nevertheless, alteration in the degree of MR among patients did not differ in the long-term follow-up (P=0.180). There was no late-term mortality or need for reoperation among patients. Conclusion: Although some centers prefer to direct implantation in ALCAPA, Takeuchi procedure can be accepted as a reliable method that provides satisfactory long-term results, considering that it aids to improve left ventricle ejection fraction and reduced mitral valve regurgitation.

ABSTRACT

Abstract Aortic arch anomalies are not clinically important unless they cause compression symptoms due to aneurysmatic dilatation. Aortic anomalies need to be treated when they cause complex thoracic aortic diseases, and the treatment approach has evolved over time from open surgical methods, which have high mortality and morbidity rates, to hybrid methods. A case of a 68-year-old male patient with complex aortic arch anomaly treated with hybrid arch repair is reported in this study. Aortic branches were common carotid trunk and aberrant right subclavian artery with a saccular aneurysm.

ABSTRACT

SUMMARY OBJECT: To explore the treatment effect of the anterior medial neurovascular interval approach to coronal shear fractures of the distal humerus. METHODS: This prospective study included two female patients who were 30-64 years old, with a mean age of 47 years. Fractures were caused by falling from a bicycle. The time between the injury and operation was 1-2 days, with a mean time interval of 1.5 days. Two patients with coronal shear fracture of the distal humerus were treated with open reduction and internal fixation using anterior neurovascular interval approach. RESULTS: There were no intraoperative and postoperative neurological and vascular complications or infections, and the fracture was united. At 12 months after the surgery, the patient returned to work without pain, and with a normal range of motion for elbow and forearm rotation. The X-rays revealed excellent fracture union, no signs of heterotopic ossification, and no traumatic arthritis. According to Mayo's evaluation standards for elbow function, a score of 100 is excellent. CONCLUSIONS: The application of the anterior neurovascular interval approach of the elbow in the treatment of shear fracture of the articular surface of the distal humerus, particularly the trochlea of the humerus, can reduce the stripping of the soft tissue.


RESUMO OBJETIVO: Explorar o efeito do tratamento com uma abordagem anterior do intervalo neurovascular médio para fraturas de cisalhamento coronal da porção distal do úmero. METODOLOGIA: Este estudo prospectivo incluiu duas pacientes do sexo feminino de 30-64 anos de idade, com idade média de 47 anos. As fraturas foram causadas por quedas de bicicleta. O tempo entre a lesão e a operação foi de 1-2 dias, com um intervalo de tempo médio de 1,5 dias. Duas pacientes com cisalhamento coronal da porção distal do úmero foram tratadas com redução aberta e fixação interna utilizando a abordagem anterior do intervalo neurovascular. RESULTADOS: Não houve complicações neurológicas e vasculares intra e pós-operatórias, nem complicações ou infecções, e a fratura foi unida. Após 12 meses da cirurgia, as pacientes retornaram ao trabalho sem dor e com uma amplitude normal de movimento de rotação do antebraço e cotovelo. Os raios-X revelaram excelente união das fraturas, sem sinais de ossificação heterotópica e sem artrite traumática. De acordo com as diretrizes da clínica Mayo para avaliação da função do cotovelo, uma pontuação de 100 é considerada excelente. CONCLUSÃO: A aplicação da abordagem anterior do intervalo neurovascular do cotovelo no tratamento de uma fratura de cisalhamento da superfície articular da porção distal do úmero, especificamente da tróclea do úmero, pode reduzir o desgaste do tecido mole.

ABSTRACT

CHIVA (Cure Conservatrice et Hemodynamique de l'Insufficience Veineuse en Ambulatoire) is a type of operation for varicose veins that avoids destroying the saphenous vein and collaterals. We report a case of CHIVA treatment of two saphenous veins to spare these veins. The patient previously had a normal great saphenous vein stripped in error in a wrong-site surgery, while two saphenous veins that did have reflux were not operated. The patient was symptomatic and we performed a CHIVA operation on the left great and right small saphenous veins. The postoperative period was uneventful and both aesthetic and clinical results were satisfactory. This case illustrates that saphenous-sparing procedures can play an important role in treatment of chronic venous insufficiency. Additionally, most safe surgery protocols do not adequately cover varicose veins operations. Routine use of duplex scanning by the surgical team could prevent problems related to the operation site


Cure conservatrice et hemodynamique de l'insufficience veineuse en ambulatoire (CHIVA) é um tipo de cirurgia de varizes que evita a destruição da veia safena e colaterais. Este relato apresenta uma paciente que foi submetida a CHIVA em duas safenas para poupá-las. A paciente teve uma safena magna normal retirada em uma cirurgia no sítio cirúrgico errado, as safenas com refluxo foram mantidas, e uma normal foi ressecada. A paciente estava sintomática e foi realizada CHIVA na safena parva direita e na magna esquerda. O pós-operatório transcorreu bem com resultado clínico e estético satisfatório. Esse caso mostra que cirurgias que poupam a safena têm papel importante no tratamento da insuficiência venosa crônica. Além disso, os protocolos de cirurgia segura não cobrem adequadamente as cirurgias de varizes devido a duas safenas possíveis e por serem frequentemente cirurgias bilaterais. A realização de eco-Doppler rotineiramente pela equipe cirúrgica pode prevenir problemas relacionados ao sítio operatório

ABSTRACT

Mostra-se relevante a elucidação da influência da densidade de energia endovenosa linear (linear endovenous energy density, LEED) média no sucesso do tratamento da insuficiência venosa crônica por termoablação endovenosa a laser visando diminuir a morbidade desse método. Objetivos Avaliar a influência da LEED média na prevalência de fechamento das safenas após 30 dias do procedimento. Métodos Foram analisados 153 membros inferiores de 118 pacientes de um hospital referência, submetidos a termoablação com laser endovenoso 1470 nm sob anestesia local para o tratamento de insuficiência venosa crônica. Foi calculada a LEED média dos pacientes tratados para determinar se foi necessária uma energia maior que a média para o sucesso do tratamento. Resultados Dos 153 membros inferiores submetidos ao tratamento, houve diferença significativa (p = 0,021) no fechamento da junção safeno-femoral relacionada à LEED média utilizada acima do joelho. Por outro lado, no segmento de coxa não houve diferença significativa. Conclusões A LEED acima da média de 70,57 J/cm apresentou um índice maior de fechamento na junção safeno-femoral. Porém, no segmento de coxa, a densidade não influenciou o resultado, demonstrando que uma energia mais alta do que 70,57 J/cm tende a não ser necessária para o tratamento desse segmento


It is relevant to elucidate the influence that mean linear endovenous energy density (LEED) has on the success of endovenous laser ablation treatment for chronic venous insufficiency, in order to reduce the method's adverse effects. Objectives To evaluate the influence of mean LEED on the prevalence of saphenous closure 30 days after the laser ablation procedure. Methods 153 lower limbs from 118 patients seen at a tertiary hospital and treated for chronic venous insufficiency with endovenous 1470 nm laser ablation under local anesthesia were evaluated. The mean LEED used to treat patients was calculated to determine whether greater than average LEED was required for treatment success. Results A significant difference (p = 0.021) in saphenofemoral junction closure was associated with mean LEED used above the knee. Conversely, there was no significant difference in the thigh segment. Conclusions Linear intravenous energy density greater than the mean of 70.57 J/cm was associated with a higher rate of closure at the saphenofemoral junction. However, density did not have an influence on the result for the thigh segment, showing that an energy density exceeding 70.57 J/cm tends not to be required for treatment of this segment

ABSTRACT

The objective of management of superior vena cava syndrome (SVCS) is to promptly alleviate the uncomfortable symptoms. Conventional approaches do not always achieve results as rapidly as endovascular management with stent placement. Objectives To report the experience with endovascular management of SVCS of a Vascular and Endovascular Surgery Service at a Brazilian university hospital. Methods Symptomatic type III SVCS cases were managed with angioplasty and stent placement in 28 patients aged from 37 to 68 years, between 2002 and 2012. The etiology of SVCS was lung or thoracic cancer in 18 patients, while occlusion of the vein for prolonged use of catheters was the cause in the other 10 cases. Results Superior vena cava occlusion repair was not possible in one oligosymptomatic patient with a very severe lesion. Technical success was achieved in 96.4%. There were two deaths, one due to pulmonary embolism, 24 hours after a successful procedure, and the other due to compression of the airways by tumor mass some hours after the procedure. Clinical success was achieved in all cases of technical success, including one patient who died suddenly, after total regression of SVCS symptoms. Symptoms disappeared 24 hours and 48 hours after management in16 and 8 patients respectively; improvement was slower but progressive after 48 hours in the remaining patients. Conclusions Endovascular stent placement was effective for management of SVCS, with good technical and clinical success rates and provided prompt relief from symptoms


O tratamento da síndrome da veia cava superior (SVCS) visa aliviar, rapidamente, os sintomas desconfortáveis. Os resultados das abordagens convencionais nem sempre são tão rápidos quanto os do tratamento endovascular com colocação de stent. Objetivos Relatar a experiência de um Serviço de Cirurgia Vascular e Endovascular de hospital universitário brasileiro com o tratamento endovascular da SVCS. Métodos Vinte e oito pacientes com SVCS sintomática tipo III foram tratados com angioplastia e colocação de stent, entre 2002 e 2012. A idade variou entre 37 e 68 anos. A SVCS resultou de doença neoplásica pulmonar ou torácica em 18 pacientes e de oclusão da veia por uso prolongado de cateteres em 10 pacientes. Resultados Não foi possível reparo da oclusão da veia em um paciente oligossintomático com lesão bastante grave. O sucesso técnico foi de 96,4%. Houve duas mortes, sendo uma por embolia pulmonar 24 horas após procedimento bem-sucedido e outra por compressão das vias aéreas por massa tumoral algumas horas após o procedimento. Houve sucesso clínico em todos os casos de sucesso técnico, incluindo o paciente que faleceu de repente após ter apresentado regressão total dos sintomas. Os sintomas desapareceram em 24 e 48 horas após o tratamento em, respectivamente, 16 e oito pacientes. A melhora foi mais lenta, embora progressiva, após 48 horas nos demais pacientes. Conclusões A colocação de stent endovascular no tratamento da SVCS foi eficaz, com boas taxas de sucesso técnico e clínico e alívio mais rápido dos sintomas

ABSTRACT

Objetivo: Presentar un caso clínico y discutir el manejo del trauma de arteria axilar y revisar la literatura actual. Caso Clínico: se presenta el caso de un paciente con lesión de arteria axilar, que es traído en shock hipovolémico al Servicio de Emergencias de nuestro hospital. En pabellón, se aprecia sección incompleta de la segunda porción de la arteria axilar. Se controla y repara con anastomosis primaria término-terminal. En su posoperatorio evoluciona de forma satisfactoria. Discusión: El manejo del trauma vascular debe ser metódico y multidisciplinario. Los signos duros de trauma vascular son indicación de exploración quirúrgica inmediata. Los pacientes con signos blandos pueden complementarse con imágenes. En una sección incompleta de arteria axilar, la anastomosis término-terminal ha mostrado buenos resultados. Conclusiones: las lesiones de arteria axilar en el contexto de traumas son infrecuentes. Su manejo necesita de un alto índice de sospecha, un enfoque multidisciplinario y un acceso quirúrgico adecuado al contexto.


Objective: To present a clinical case and discuss the management of axillary artery trauma and to review current literature. Clinical case: Male patient with axillary artery injury, who is brought in hypovolemic shock to the Emergency Department. Surgical findings demonstrated an incomplete section of the second portion of the axillary artery which was repaired with primary end-to-end anastomosis. Postoperatively, the patient evolves without pain and is discharged. Discussion: The management of vascular trauma should be methodical and multidisciplinary. Hard signs of vascular trauma mandate immediate surgical exploration. Patients with soft signs may need further evaluation with images. In an incomplete section of the axillary artery the end-to-end anastomosis has shown good results. Conclusions: Axillary artery lesions in the context of trauma are infrequent. Its management requires a high index of suspicion, a multidisciplinary approach and adequate surgical access.

ABSTRACT

O uso de simuladores na educação médica tem sido cada vez mais frequente, porém pouco acessíveis devido ao custo elevado. Foi desenvolvido para tal um modelo acessível e de baixo custo para o aprendizado e o treinamento de suturas e anastomoses vasculares em Laboratório de Bases das Técnicas Cirúrgicas. Foram utilizados balões de látex de cores variadas, fio de polipropileno 6.0 e outros materiais específicos para sutura vascular (porta-agulhas e pinças). Para facilitar o reparo dos balões, eles foram fixados em parafusos sobre placas de madeira. Foram feitas anastomoses terminoterminal, terminolateral e laterolateral e construção de patch. A perviedade da anastomose foi testada a partir da injeção de água em uma extremidade do balão e a observação da saída do conteúdo líquido na extremidade oposta. As vantagens observadas nesse modelo de treinamento para anastomoses foram a maleabilidade, a resistência à passagem do fio e o fato de ser inorgânico. Os balões de látex são uma alternativa barata, viável, não perecível e de uso prolongado no ensino e treinamento das suturas e anastomoses arteriais


Simulators are increasingly being used in medical education, but accessibility is restricted by their elevated cost. A accessible and low-cost model was developed for teaching and learning vascular sutures and anastomoses at a Basic Surgical Techniques Laboratory. Latex balloons of varying colors, polypropylene 6.0 sutures, and other materials specifically for suturing (needle holder and forceps) were used. The balloons were fixed to screws inserted into wooden boards in order to facilitate repairs. E end-to-end, end-to-side, and side-to-side anastomoses and patching were performed. Anastomosis patency was tested by injecting water into one extremity of the balloon and observing the liquid exit via the opposite extremity. The advantages observed with this training model for anastomoses were malleability, resistance to passage of the suture, and the fact that it is inorganic. Latex balloons are an inexpensive option that are non-perishable and offer prolonged use for teaching and practice of arterial sutures and anastomoses

ABSTRACT

Resumen: El tratamiento de aneurismas intracraneanos rotos y no rotos incluye opciones quirúrgicas (clips vasculares) y endovasculares. Existen varios dispositivos y técnicas de manejo endovascular (coils, stents, diversores de flujo), cuyo conocimiento permite elegir e interpretar adecuadamente las técnicas de imágenes para el seguimiento no invasivo. Mediante una revisión pictográfica del control de aneurismas intracraneanos tratados quirúrgicamente y vía endovascular, se muestran las diferencias en la capacidad de caracterización en el seguimiento con angio TC, angio RM sin contraste (con técnica de "tiempo de vuelo" o "TOF" por sus siglas en inglés), angio RM con gadolinio endovenoso (C+) y angiografía por sustracción digital (ASD). Adicionalmente se entregan recomendaciones para el seguimiento de aneurismas según modalidad y dispositivo de tratamiento.


Abstract: Treatment of intracranial ruptured and unruptured aneurysms can be performed with surgical (vascular clips) or endovascular procedures (coils, stents, flw diverters). There are several devices and techniques for endovascular treatment. Knowledge of this techniques allows physicians to choose and interpret accurately imaging modalities for non-invasive follow-up. Through a pictorial essay of imaging follow-up of treated intracranial aneurysms we show the differences in characterization with computed tomography angiography, magnetic resonance angiography without contrast (time of flght or "TOF" technique), contrast enhanced MR angiography (C+) and digital subtraction angiography (DSA). Additionally we recommend imaging modalities for each treatment device.

ABSTRACT

Abstract Purpose: To introduce a nonliving microvascular training model based on vessels diameter and feasibility. Methods: We dissected ten oxen tongues, and divided the pedicles into three-thirds: proximal, middle and distal. We measured the external vessels diameter in all regions. We performed a descriptive statistical analysis. Three students (two beginner level and one intermediate level) performed this training. We evaluated the confidence, according Likert scale. Results: We dissected all oxen tongues, each tongue showed two parallel pedicles. Each pedicle was located at 1.5 - 2.0 cm from the midline. Proximal median artery and vein diameter were 3.9 ± 0.7, and 5.04 ± 1.44mm, respectively. In the middle third, the mean artery diameter was 3.3 ± 0.4mm, and the vein diameter was 3.5 ± 0.9mm. The distal third showed a mean artery diameter of 2.0 ± 0.42mm, and a vein diameter of 2.4 ± 0.82mm. The students performed ten anastomoses. This study showed a higher confidence level (CL) (p=0.03) than the pre training CL assessment. Conclusion: This study suggested a feasible non-animal model for microsurgical training process for beginners and intermediate trainees.

ABSTRACT

Abstract Vascular bypass is a surgical procedure widely used to treat peripheral vascular disease. The intraoperative anesthetic technique and the most appropriate postoperative analgesia for these high-risk patients remain controversial. We present the case of a patient undergoing femoropopliteal-distal bypass in our service, presenting with relevant comorbidities to the choice of anesthetic technique. This patient had several determining factors of difficult airway, especially thoracic kyphoscoliosis, which prevented him from being properly positioned for airway management, and chronic lung disease. This patient was also taken antiplatelet drugs, which is a contraindication for neuraxial block. So, we chose the anesthetic technique of peripheral nerve block, specifically the blockade of femoral and sciatic nerves.


Resumo A cirurgia para bypass vascular é um procedimento amplamente usado para o tratamento da insuficiência vascular periférica. A técnica anestésica para o intraoperatório e para analgesia pós-operatória mais apropriada para esses pacientes de alto risco ainda permanece controversa. Apresentaremos o caso de um paciente submetido a bypass femoropoplíteo distal no nosso serviço, que apresentava comorbidades relevantes para a escolha da técnica anestésica. Esse paciente apresentava fatores determinantes de via aérea difícil, principalmente cifoescoliose da coluna torácica, que o impedia de ser posicionado adequadamente para o manejo da via aérea, além de ser portador de patologia pulmonar crônica. Também fazia uso de antiplaquetários que contraindicavam o bloqueio de neuroeixo. Por isso, optou-se como técnica anestésica pelo bloqueio de nervos periféricos, especificamente o bloqueio dos nervos femoral e isquiático.

ABSTRACT

Em todo paciente submetido a reparo endovascular do aneurisma de aorta abdominal (REVA) que se apresente subitamente com quadro de dor abdominal ou sinais de choque, a hipótese de endoleak ou vazamento, com expansão do aneurisma e ruptura deve ser aventada. Apresentamos o caso de um paciente em pós-operatório de REVA que apresentou uma neoplasia de duodeno mimetizando um endoleak


Whenever a patient who has undergone endovascular repair of an abdominal aortic aneurysm (EVAR) presents with sudden onset abdominal pains or signs of shock, the hypothesis of endoleak with aneurysm expansion and rupture should be considered. We present the case of an EVAR patient in whom a tumor of the duodenum mimicked an endoleak during the postoperative period

ABSTRACT

Resumo Contexto As amputações dos membros inferiores, sejam definidas como maiores ou menores, são um grave problema de saúde, com altos índices de morbimortalidade e de relevante impacto social. Diferentes características clínicas dos pacientes parecem estar relacionadas aos diferentes tipos de amputação realizados. Objetivos Analisar os fatores de risco presentes em pacientes submetidos a amputações de membros inferiores em hospital terciário. Métodos Estudo retrospectivo, transversal, envolvendo 109 pacientes submetidos a amputação de membro inferior em um período de 31 meses, através da análise de gênero e idade, 15 dados clínicos e cinco parâmetros laboratoriais presentes no momento da admissão. Os dados foram submetidos a estatística descritiva e comparativa através do teste t de Student não pareado (para variáveis numéricas), e dos testes de Mann-Whitney e exato de Fisher (para variáveis categóricas). Resultados Das 109 amputações realizadas, 59 foram maiores e 50 menores. A maioria dos pacientes era do gênero masculino (65%), e a média de idade foi de 65 anos (mín. 39, máx. 93). Dentre os fatores de risco observados, idade avançada, acidente vascular encefálico, isquemia, sepse e níveis baixos de hemoglobina e hematócrito estavam estatisticamente mais relacionados às amputações maiores (p < 0,05). Diabetes melito, neuropatia e pulsos distais palpáveis foram fatores mais associados às amputações menores. Conclusões Os níveis das amputações de membros inferiores estão relacionados a diferentes fatores de risco. Os quadros isquêmicos mais graves e de maior morbidade estiveram associados a amputações maiores, enquanto a neuropatia e perfusão preservada, mais relacionados às amputações menores.


Abstract Background Whether they are defined as minor or major, lower limb amputations constitute a severe health problem, causing high rates of morbidity and mortality and considerable social impact. Different patient clinical characteristics appear to be related to different types of amputations. Objectives To analyze risk factors present in patients who underwent lower limb amputations at a tertiary hospital. Methods This was a retrospective, cross-sectional study of 109 patients who underwent lower limb amputations over a period of 31 months, analyzing gender, age, 15 clinical data and five laboratory parameters present at the time of admission. Data were treated with descriptive statistics and compared using Student’s t test for unpaired samples (for numerical variables), the Mann-Whitney test, or Fisher’s exact tests (for categorical variables). Results There were 59 major and 50 minor amputations out of a total of 109 performed. The majority of patients were male (65%) and mean age was 65 years (range 39 to 93). Risk factors that were statistically (p < 0.05) more related to major amputations were advanced age, stroke, ischemia, sepsis, and low hemoglobin and hematocrit levels. Diabetes mellitus, neuropathy, and palpable distal pulses were factors more strongly associated with minor amputations. Conclusions Lower limb amputations at different levels are related to different risk factors. Ischemia of greater severity and morbidity was associated with major amputations, while neuropathy and preserved perfusion were more often related to minor amputations.

ABSTRACT

ABSTRACT Paraclinoid aneurysms are lesions located adjacent to the clinoid and ophthalmic segments of the internal carotid artery. In recent years, flow diverter stents have been introduced as a better endovascular technique for treatment of these aneurysms. Method From 2009 to 2014, a total of 43 paraclinoid aneurysms in 43 patients were surgically clipped. We retrospectively reviewed the records of these patients to analyze clinical outcomes. Results Twenty-six aneurysms (60.5%) were ophthalmic artery aneurysms, while 17 were superior hypophyseal artery aneurysms (39.5%). The extradural approach to the clinoid process was used to clip these aneurysms. One hundred percent of aneurysms were clipped (complete exclusion in 100% on follow-up angiography). The length of follow-up ranged from 1 to 60 months (mean, 29.82 months). Conclusion Surgical clipping continues to be a good option for the treatment of paraclinoid aneurysms.


RESUMO Aneurismas paraclinóideos são lesões localizadas adjacentes aos segmentos clinóideos e oftálmicos da artéria carótia interna. Os stents desviadores de fluxo tem sido crescentemente aplicados com sucesso. Métodos De 2009 a 2014, um total de 43 aneurismas paraclinóideos foram clipados em 43 pacientes. Analisamos retrospectivamente os dados dos pacientes e desfechos clínicos. Resultados Vinte seis aneurismas (60,5%) foram de artéria oftálmica e 17 de artéria hipofisária superior (39,5%). O acesso extradural à clinóide foi utilizado para todos aneurismas. Cem por cento dos aneurismas foram clipados com oclusão de 100% na angiografia controle. O tempo de follow-up oscilou de 1 a 60 meses, com media de 29 meses. Conclusão A clipagem cirúrgica é uma opção boa e segura para o tratamento de aneurismas paraclinóideos.
