ABSTRACT

Contexto: Vários estudos realizados em climas temperados sugerem que há uma variação na incidência de tromboembolismo venoso (TEV) de acordo com as estações climáticas. Entretanto, nenhum estudo foi feito comparando áreas de clima semiárido com áreas de clima temperado. Objetivos: Analisar se existe correlação entre a incidência do TEV em áreas de clima semiárido e de clima temperado no Brasil. Métodos: Foi feito um levantamento de dados retrospectivos de pacientes com diagnóstico de TEV no Sistema Único de Saúde de janeiro de 2011 a dezembro de 2014 provenientes dos seguintes estados com clima semiáridos: Alagoas, Ceará, Maranhão, Paraíba, Pernambuco, Piauí e Rio Grande do Norte, localizados na Região Nordeste do Brasil; e dos seguintes estados com clima temperado: Paraná, Santa Catarina e Rio Grande do Sul, localizados na Região Sul do Brasil. Os dados de variação climática foram obtidos do Instituto Nacional de Meteorologia e os dados populacionais do Instituto Brasileiro de Geografia e Estatística. Resultados: Houve correlação significativa na incidência de casos de TEV em regiões de temperaturas mais baixas (p < 0,001). A Região Sul apresentou temperaturas significativamente menores que as da Região Nordeste (p < 0,001) e apresentou número significativamente maior de casos de TEV do que a Região Nordeste (p < 0,001). Conclusão: Há mais casos de TEV em regiões de clima temperado, onde as temperaturas são mais baixas. No entanto, pouco ainda é conhecido na literatura sobre a flutuação sazonal e a incidência de TEV. Sendo assim, mais estudos são necessários nessa área


Background: Several studies conducted in areas with temperate climates have suggested that the incidence of venous thromboembolism (VTE) varies depending on seasonal climatic fluctuations. However, no studies have been conducted comparing areas with semi-arid climate with areas with temperate climates. Objectives: To analyze whether there is a correlation between the incidence of VTE in areas with semi-arid climates and areas with temperate climates in Brazil. Methods: Retrospective data were acquired for patients diagnosed with VTE from January 2011 to December 2014 from the Brazilian National Health Service for the following Brazilian states that have semi-arid climates: Alagoas, Ceará, Maranhão, Paraíba, Pernambuco, Piauí, and Rio Grande do Norte (all located in the Northeast Region of Brazil); and the following states with temperate climates: Paraná, Santa Catarina, and Rio Grande do Sul (all located in the South Region of Brazil). Data on climatic variation were obtained from the National Meteorological Institute and population data were obtained from the Brazilian Institute of Geography and Statistics. Results: There was a significant correlation in the incidence of VTE cases in areas with lower temperatures (p < 0.001). The South Region exhibited significantly lower temperatures than the Northeast Region (p < 0.001) and had a significantly higher number of cases of VTE than the Northeast Region (p < 0.001). Conclusions: There are more cases of VTE in areas with temperate climates, where temperatures are lower. However, there is still little information in the literature on seasonal fluctuations and incidence of VTE. More studies of this subject are needed

ABSTRACT

Contexto: Devido à maior aplicação de exames de imagem rotineiros, especialmente nos pacientes com neoplasia para controle da doença, vem aumentando o diagnóstico de tromboembolismo pulmonar (TEP) incidental, importante fator de morbimortalidade associado. Objetivo: Identificar os casos de TEP incidental em pacientes oncológicos submetidos a tomografia computadorizada (TC) de tórax, correlacionando aspectos clínicos e fatores de risco associados. Métodos: Estudo retrospectivo de todos os episódios de TEP ocorridos de janeiro de 2013 a junho de 2016, com seleção dos pacientes oncológicos e divisão deles em dois grupos: com suspeita clínica e sem suspeita clínica (incidentais) de embolia pulmonar. Resultados: Foram avaliados 468 pacientes com TEP no período citado. Destes, 23,1% eram oncológicos, entre os quais 44,4% apresentaram achado incidental de embolia pulmonar na TC de tórax. Não houve diferença estatística entre os grupos para sexo, idade e tabagismo. Quanto à procedência, 58,3% dos pacientes sem suspeita clínica eram de origem ambulatorial e 41,7% com suspeita de TEP vinham do pronto-socorro (p < 0,001). As neoplasias mais prevalentes foram de pulmão (17,6%), intestino (15,7%) e mama (13,0%). Aqueles com achado incidental apresentaram significativamente mais metástases, sem diferença entre os grupos para realização de quimioterapia, radioterapia ou cirurgia recente. Quanto aos sintomas apresentados, 41,9% daqueles sem suspeita clínica tinham queixas sugestivas de TEP quando realizaram o exame. Conclusão: TEP incidental é frequente em pacientes oncológicos, especialmente naqueles provenientes de seguimento ambulatorial e em estágios avançados da doença. Sintomas sugestivos de TEP estavam presentes em pacientes sem suspeita clínica ao realizarem a TC de tórax


Background: Increased use of routine imaging exams has led to higher rates of incidental diagnosis of pulmonary thromboembolism (PTE), especially for management of disease in cancer patients, among whom it is an important factor in associated morbidity and mortality. Objective: To identify cases of incidental PTE in cancer patients examined with computed tomography (CT) of the thorax, correlating clinical features and associated risk factors. Methods: This is a retrospective study of all episodes of PTE diagnosed between January 2013 and June 2016, selecting cases involving cancer patients and dividing them into two subsets: those with clinical suspicion and those without clinical suspicion of pulmonary embolism (incidental cases). Results: At total of 468 patients had PTE during the period investigated and 23.1% of them were cancer patients, 44.4% of whom exhibited pulmonary embolism as an incidental finding of a chest CT. There was no statistical difference between the two subsets in terms of sex, age, or smoking. In terms of patients' admission status, 58.3% of the patients without clinical suspicion were outpatients and 41.7% of those with suspicion of PTE were admitted via the emergency room (p < 0.001). The most common cancer sites were lung (17.6%), intestine (15.7%), and breast (13.0%). Patients whose PTE were diagnosed incidentally exhibited a significantly greater rate of metastases, while there were no differences between the groups in terms of chemotherapy, radiotherapy, or recent surgery. Analysis of symptoms revealed that 41.9% of patients without clinical suspicion had complaints suggestive of PTE when they underwent the CT examination. Conclusions: Incidental PTE is common among cancer patients, especially those in outpatients follow-up and in advanced stages of the disease. Patients without clinical suspicion also had symptoms suggestive of PTE when they presented for chest CT

ABSTRACT

CONTEXTO: Aproximadamente 60% dos pacientes portadores de doença arterial oclusiva crônica periférica têm doença coronariana grave, sendo que a principal causa de morte no pós-operatório de cirurgia vascular de grande porte é o infarto agudo do miocárdio. OBJETIVOS: Determinar a prevalência da doença coronariana em pacientes submetidos a cirurgia vascular eletiva de grande porte e sua relação com as complicações cardiológicas pós-operatórias. MÉTODOS: Foram analisados 200 pacientes submetidos a cirurgia vascular arterial eletiva: doença obstrutiva carotídea, aortoilíaca e femoropoplítea distal e doença aneurismática de aorta abdominal e de artérias ilíacas. Os pacientes constituíram três grupos: grupo I, sem doença coronariana; grupo II, com doença coronariana assintomática; e grupo III, com doença coronariana sintomática. As complicações cardiológicas consideradas foram infarto agudo do miocárdio fatal e não fatal, insuficiência cardíaca congestiva, choque cardiogênico, fibrilação atrial aguda e outras arritmias. RESULTADOS: Complicações cardíacas ocorreram em 11 pacientes (5,5%): três infartos agudos do miocárdio não fatais (1,5%) sempre em pacientes do grupo III. A complicação cardíaca mais frequente foi arritmia (exceto fibrilação atrial) ocorrida em cinco (2,5%) pacientes, sendo três do grupo II. A mortalidade precoce foi de nove pacientes (4,5%). Apenas uma morte foi decorrente de problema cardíaco: choque cardiogênico em paciente do grupo III. CONCLUSÕES: A doença coronariana não foi preditora de óbito nos pacientes submetidos a cirurgia vascular periférica de grande porte. A sobrevida dos pacientes com ou sem doença coronariana não mostrou diferenças estatísticas.


BACKGROUND: Approximately 60% of patients with chronic occlusive peripheral arterial disease have severe coronary disease and the principal cause of death during the postoperative period after major vascular surgery is acute myocardial infarction. OBJECTIVES: To determine the prevalence of coronary disease among patients scheduled for elective major vascular surgery and its relationship with postoperative cardiological complications. METHODS: A total of 200 patients who underwent elective vascular arterial surgery for obstructive carotid disease, aortoiliac and distal femoropopliteal disease and aneurysmal disease of the abdominal aorta and iliac arteries were analyzed. These patients were allocated to three groups: group I, free from coronary disease; group II, asymptomatic coronary disease; and group III, symptomatic coronary disease. The cardiological complications analyzed were fatal and nonfatal acute myocardial infarction, congestive heart failure, cardiogenic shock, acute atrial fibrillation and other arrhythmias. RESULTS: Cardiac complications occurred in 11 patients (5.5%): three nonfatal acute myocardial infarctions (1.5%), all in patients from group III. The most common cardiac complication was arrhythmia (excluding atrial fibrillation) in five (2.5%) patients, three from group II. Early mortality was nine patients (4.5%). Just one death was caused by a cardiac problem: cardiogenic shock in a patient from group III. CONCLUSIONS: Coronary disease was not predictive of death among patients who underwent major peripheral vascular surgery. There were no statistical differences in survival between patients with or without coronary disease.

ABSTRACT

OBJECTIVE: to evaluate the efficacy of endovascular repair of popliteal artery aneurysms on maintaining patency of the stent in the short and medium term. METHODS: this was a retrospective, descriptive and analytical study, conducted at the Integrated Vascular Surgery Service at the Hospital da Beneficência Portuguesa de São Paulo. We followed-up 15 patients with popliteal aneurysm, totaling 18 limbs, treated with stent from May 2008 to December 2012. RESULTS: the mean follow-up was 14.8 months. During this period, 61.1% of the stents were patent. The average aneurysm diameter was 2.5 cm, ranging from 1.1 to 4.5 cm. The average length was 5 cm, ranging from 1.5 to 10 cm. In eight cases (47.1%), the lesion crossed the joint line, and in four of these occlusion of the prosthesis occurred. In 66.7% of cases, treatment was elective and only 33.3% were symptomatic patients treated on an emergency basis. The stents used were Viabahn (Gore) in 12 cases (66.7%), Fluency (Bard) in three cases (16.7%), Multilayer (Cardiatis) in two cases (11.1%) and Hemobahn (Gore) in one case (5.6%). In three cases, there was early occlusion (16.6%). During follow-up, 88.2% of patients maintained antiplatelet therapy. There was no leakage at ultrasound (endoleak). No fracture was observed in the stents. CONCLUSION: the results of this study are similar to other published series. Probably, with the development of new devices that support the mechanical characteristics found on the thighs, there will be improved performance and prognosis of endovascular restoration.

ABSTRACT

There is a growing demand for invasive procedures involving the inferior vena cava, in particular for placement of vena cava filters. It is not always easy to identify the more distal renal vein with cavography, for safe release of filters. OBJECTIVES: To determine parameters for the relationships between the renal veins and the infrarenal vena cava and their corresponding vertebral bodies, their relationships with biotype and the occurrence of anatomic variations, the relationships between vertebral bodies and the bifurcation of the common iliac veins and the distance from this bifurcation to the outflow of the more distal renal vein, with reference to placement of vena cava filters. METHODS: A total of 150 abdominal computed tomography scans conducted from October to November 2011 were analyzed and classified according to the biotype exhibited (using Charpy's angle). Scans were performed at MEDIMAGEM and analyzed at the Integrated Vascular Surgery Service, both part of Hospital da Beneficência Portuguesa in São Paulo, Brazil. RESULTS: In 127 of the 150 scans analyzed (84.66%), the more distal renal vein emerged between the first lumbar intervertebral space (L1-L2) and the body of L2, irrespective of patient biotype. Just 23 patients (15.33%) exhibited a more distal renal vein with outflow below the body of L2, i.e. in the projection of the space between L2 and L3. CONCLUSIONS: The radiological correlation between the confluence of the more distal renal vein and vertebral bodies exhibits little variation, irrespective of the biotype of the patient...


Há uma demanda crescente por procedimentos invasivos que abordam a veia cava inferior, especialmente o implante de filtros de veia cava. A identificação da veia renal mais caudal para a liberação segura do filtro nem sempre é fácil durante a cavografia. OBJETIVOS: Estabelecer parâmetros da relação das veias renais e da cava infrarrenal com o corpo vertebral correspondente, sua relação com a biotipologia, presença de variações anatômicas, relação dos corpos vertebrais com a bifurcação das veias ilíacas comuns para a veia cava e distância desta bifurcação até a desembocadura da veia renal mais caudal, visando à implantação de filtro de veia cava. MÉTODOS: Foram analisadas 150 tomografias computadorizadas de abdome no período entre outubro e novembro de 2011, tendo sido agrupadas de acordo com o biotipo apresentado (ângulo de Charpy). As tomografias forem realizadas na MEDIMAGEM e analisadas no Serviço de Cirurgia Vascular Integrada, ambas da Beneficência Portuguesa de São Paulo. RESULTADOS: Dos 150 exames analisados, 127 (84,66%) apresentaram a emergência da veia renal mais caudal desde a projeção do primeiro espaço intervertebral lombar (L1-L2) até o corpo de L2, independentemente do biotipo do paciente. Somente 23 pacientes (15,33%) apresentaram a desembocadura da veia renal mais caudal abaixo do corpo de L2, ou seja, na projeção do espaço entre L2 e L3. CONCLUSÕES: A correlação radiológica da confluência da veia renal mais distal em relação aos corpos vertebrais apresenta pouca variação, independentemente do biotipo do paciente...

OBJETIVO: Avaliar a eficácia da correção endovascular do aneurisma de artéria poplítea quanto à manutenção da perviedade da endoprótese, em curto e médio prazo. MÉTODOS: trata-se de estudo retrospectivo, descritivo e analítico, realizado no Serviço de Cirurgia Vascular Integrada do Hospital Beneficência Portuguesa de São Paulo. Foram acompanhados 15 pacientes com aneurisma de poplítea totalizando 18 membros tratados com endoprótese, no período de maio de 2008 a dezembro 2012. RESULTADOS: o tempo médio de seguimento foi 14,8 meses. Nesse período, 61,1% das endopróteses estavam pérvias. A média de diâmetro dos aneurismas foi 2,5cm, variando de 1,1 a 4,5cm. A extensão média encontrada foi 5cm, variando de 1,5 a 10cm. Em oito casos (47,1%), a lesão cruzava a linha articular e, em quatro destes, ocorreu oclusão da prótese. Em 66,7% dos casos, o tratamento foi eletivo e apenas 33,3% eram pacientes sintomáticos, tratados em caráter de urgência. As endopróteses usadas foram a Viabahn (Gore) em 12 casos (66,7%), Fluency (Bard) em três casos (16,7%), Multilayer (Cardiatis) em dois casos (11,1%) e Hemobahn (Gore) em apenas um caso (5,6%). Em três casos, ocorreu oclusão precoce (16,6%). Durante o seguimento, 88,2% dos pacientes mantiveram a antiagregação plaquetária. No seguimento ultrassonográfico não foi observado nenhum vazamento (endoleak). Não foi verificada nenhuma fratura nos Stents. CONCLUSÃO: Os resultados obtidos nesse estudo são semelhantes aos de outras séries publicadas. Provavelmente com o desenvolvimento de novos dispositivos que suportem as particularidades mecânicas encontradas na região poplítea, haverá como melhorar o desempenho e prognóstico da restauração endovascular.

ABSTRACT

CONTEXT: Anticoagulation with warfarin is considered the appropriate treatment for venous thromboembolism and other thrombotic pathologies. Regular INR control is required for dosage adjustment and therapeutic control. Use of portable monitoring systems optimizes management of these patients. OBJECTIVE: To compare INR measurements taken using the portable Coaguchek XS system in capillary blood with the standard laboratory method using venous blood. METHOD: Fifty-two samples each of venous and capillary blood were collected from nineteen patients on warfarin, who had been admitted to the Hospital da Beneficência Portuguesa de São Paulo, and analyzed using the conventional method and the Coaguchek XS system, respectively. RESULTS: Spearman's correlation coefficient ® for the overall performance of the two methods was 0.978 (p<0.0001; 95%CI 0.961-0.988). The Kappa measure of agreement for all patients was 76.8% (p<0.001; IC: 95% 0.975-0.561). Mean INR according to the Coaguchek XS system underestimated the values provided by the conventional method by -0.01 INR points, with a standard error of 0.342. Results for INR values greater than 3.5 were satisfactory with a correlation coefficient of 0.71, but without statistical significance (p>0.714). CONCLUSIONS: The Coaguchek XS system can be used to monitor prothrombin time in patients on oral anticoagulants, provided INR values greater than 3.5 are confirmed using the conventional laboratory method...


CONTEXTO: Anticoagulação por varfarina (warfarin) é considerada tratamento adequado para tromboembolismo venoso e outras patologias trombóticas. Deve ser realizada a mensuração do Índice Internacional Normalizado (INR) para ajuste de dosagem de medicamento para manutenção dos pacientes na faixa terapêutica. O uso de dispositivos portáteis otimiza o controle desses pacientes. OBJETIVO: Comparar as medidas do INR realizadas pelo sistema portátil Coaguchek XS, em sangue capilar, com o método laboratorial padrão em sangue venoso. MÉTODO: Dezenove pacientes em uso de varfarina, internados no Hospital da Beneficência Portuguesa de São Paulo, foram submetidos à coleta de 52 amostras analisadas pelo método convencional e coleta de sangue capilar para medida com o sistema Coaguchek XS. RESULTADOS: O coeficiente de correlação (r) de Spearman por meio da comparação de desempenho global entre os dois métodos foi de 0,978 (p<0,0001; IC: 95% 0,961-0,988). O percentual de concordância Kappa para todas as faixas foi de 76,8% (p<0,001; IC: 95% 0,975-0,561). O INR médio do sistema Coaguchek XS subestimou os valores obtidos em -0,01 pontos de INR, quando comparado ao método convencional, com erro padrão de 0,342. Valores acima de 3,5 mostraram resultados satisfatórios com coeficiente de correlação de 0,71, mas sem significância estatística (p>0,714). CONCLUSÕES: O sistema Coaguchek XS pode ser utilizado na monitorização do tempo de protrombina em pacientes com uso de anticoagulantes orais, desde que valores de INR acima de 3,5 sejam confirmados por meio de medidas realizadas em laboratório convencional...

ABSTRACT

OBJECTIVE: The phase III EINSTEIN DVT and EINSTEIN PE trials demonstrated the potential of oral rivaroxaban for the treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE). The length of initial hospitalization in patients presenting with either symptomatic DVT or PE was assessed using hospitalization records from these trials. METHODS: Analyses were carried out in the intention-to-treat population, using non-parametric and parametric statistical methods. RESULTS: Overall, 52% (1781/3434) of EINSTEIN DVT patients and 90% (4328/4821) of EINSTEIN PE patients were admitted to hospital. The proportion of hospitalized patients with a length of stay of five or fewer days receiving rivaroxaban was 54% compared with 31% for enoxaparin/vitamin K antagonist (VKA) in patients with DVT. For patients with PE, the corresponding values were 45% and 33%. Stays of 6-10 days were observed in 29% of rivaroxaban-treated patients compared with 45% of enoxaparin/VKA-treated patients for DVT. For patients with PE, these values were 39% and 46% in the rivaroxaban and enoxaparin/VKA groups, respectively. Overall, length of stay was significantly shorter in the rivaroxaban group, compared with the enoxaparin/VKA group across all analyses performed (p < 0.0001). Across regions, the observed admission rates and length of stay duration varied greatly: Asia had the longest overall hospitalization rates, whereas the lowest rates were reported in North America, Australia and New Zealand. Nevertheless, a consistent trend was observed: length of hospital stay in patients with DVT or PE receiving rivaroxaban was shorter than, or at least similar to, patients receiving enoxaparin/VKA. CONCLUSION: A single-drug regimen with rivaroxaban may reduce the burden on healthcare systems and patients, and provides effective and well tolerated treatment. The studies shared an open-label design that allowed comparison of initial hospitalization, but limitations include the well monitored clinical trial setting in which decisions on admission and discharge could vary from real-world management.

ABSTRACT

OBJETIVO: A via de acesso mais utilizada à aorta abdominal para correção da doença obstrutiva ou aneurismática é a transperitoneal, sendo que a retroperitoneal é muitas vezes apontada como causando menos complicações. O objetivo deste estudo é comparar as duas vias no tocante às complicações tardias. MÉTODO: Para comparação da evolução tardia, foram estudados 96 pacientes retrospectivamente, sendo 81 portadores de aneurisma e 15 de doença aorto-ilíaca. A via retroperitoneal foi usada em 43 pacientes, e a transperitoneal, em 53. RESULTADOS: Não houve diferença entre as ocorrências de hérnia incisional, flacidez de parede abdominal e ejaculação retrógrada. CONCLUSÕES: Não foram observadas diferenças entre os dois tipos de acesso quanto aos parâmetros considerados na avaliação tardia.


OBJECTIVE: The transperitoneal approach to the abdominal aorta for surgery of either occlusive or aneurysmal disease is undoubtedly the most often used approach, although the retroperitoneal approach is frequently mentioned as being less prone to complications. The aim of this study was to compare both approaches regarding late complications. METHOD: Late results were retrospectively studied in 96 patients (81 cases of aortic aneurysm and 15 cases of obstructive disease). The retroperitoneal approach was used in 43 cases and the transperitoneal in 53. RESULTS: There were no significant differences in the occurrence of incisional hernia, abdominal bulging, and retrograde ejaculation. CONCLUSIONS: There were no differences between the two procedures regarding the parameters considered for late assessment.

ABSTRACT

OBJECTIVE: To prospectively assess early and late morbidity and mortality of patients undergoing elective surgical repair of abdominal infrarenal aortic aneurysms and to determine the independent predictors of cardiac events. METHODS: For 6 consecutive years, this study analyzed 130 patients, who underwent routine standardized preoperative assessment always with the same clinical, surgical, and anesthesia teams. RESULTS: In-hospital mortality was 3.1% (4 patients), and the major cause of death was mesenteric ischemia, which occurred in 3 patients. Forty-eight (37%) nonsurgical complications occurred as follows: 8.5% were cardiac complications and 28.5% were noncardiac complications. The most common complications were the pulmonary ones, which occurred in 14 (10.8%) patients. Survivals in the first, third, and sixth postoperative years were 95%, 87%, and 76%, respectively. The variables that significantly correlated with morbidity and mortality were clinical predictors, mean age of 70.5 years, and presence of heart failure and chronic renal failure. No predictor of late morbidity and mortality was identified. CONCLUSION: Although this is considered a highly complex surgery, mortality is low, the cardiac complications are not very significant, and the patients have a good long-term evolution.

ABSTRACT

OBJETIVO: Avaliar o impacto da implantação da cirurgia endovascular (CEV) em um serviço de cirurgia vascular convencional (CVC). MÉTODO: Análise retrospectiva dos procedimentos vasculares nos últimos 11 anos, dos procedimentos arteriais, anuais e por residente, entre 1999 (implantação da CEV) e 2003, e das cirurgias com cirurgiões endovasculares e convencionais e por cirurgiões convencionais apenas. Foi também avaliado o percentual de encaminhamentos das CEV a serviço intervencionista. RESULTADOS: Houve uma queda inicial no número de procedimentos arteriais que foi recuperada após a implantação do serviço de CEV. O percentual das CEV no número total de cirurgias arteriais passou de 3,6 por cento em 1999 para 25 por cento em 2003 (p<0,05). Não houve queda no número de cirurgias convencionais realizadas pelos residentes, mas houve um aumento no número de CEV por residente por ano de 2,6 em 1999 para 20 em 2003. Todas as CEV foram realizadas no nosso próprio serviço em 2003. Houve um aumento do número de cirurgiões que operam por via endovascular e convencional em relação aos que operam apenas por via aberta (p<0.05). CONCLUSÕES: Sem implantação da CEV parece cair o volume de procedimentos globais, mas se mantida dentro do serviço, a CEV pode levar à recuperação, inclusive com aumento das CVC. Não houve prejuízo para o treinamento dos residentes em relação à CVC, e sim a melhora do treinamento em CEV. A implantação da CEV gera um decréscimo no encaminhamento de pacientes. O cirurgião vascular e endovascular têm um volume progressivamente maior comparado com aqueles com treinamento apenas em CVC.


BACKGROUND: The aim of this study was to evaluate the impact of endovascular surgery (EVS) upon a standard vascular surgical service. METHODS: Retrospective analysis of all vascular procedures of the last 11 years, the annual number of arterial procedures, the fellows surgical volume as well as the percentage of patients referred to radiology between 1999 (implantation of EVS) and 2003, and the surgical volume of surgeons able to perform both operation and those who perform only standard surgery (SS). RESULTS: An initial decrease in the number of arterial procedures was observed, but recovered after EVS implantation. The percentage of EVS increased from 3.6 percent in 1999 to 25 percent in 2003 (p<0.05). There was no decrease in the number of fellows performing SS, yet an increase in their annual number of EVS was observed (2.6 in 1999 and 20 in 2003). All procedures were referred to radiology before 1999 versus none in 2003. Surgeons that perform both operations had an increase in their surgical volume compared to surgeons that perform only SS (p<0.05). CONCLUSION: Without implantation of EVS a decrease of vascular procedures can occur. On the other hand, EVS can lead to a recovery of surgical volume, including an increase in the SS. There was no decrease in the fellowsæ volume of SS, but a improvement in EVS training. Referral of patients to other services can be diminished with EVS implantation. Surgeons that perform both operations have a progressive increase in their volume when compared to those who perform only SS.

ABSTRACT

Os autores relatam dois casos de escleroterapia de telangiectasias, as quais complicaram com trombose venosa profunda. O primeiro caso foi confirmado por flebografia, e o segundo, por duplex scan. Um paciente, 8 anos após, apresentou uma tromboflebite espontânea de veia safena parva, que resultou em pesquisa de trombofilia positiva para o Fator V Leiden. A outra paciente teve pesquisa de trombofilia negativa. Os relatos de tromboembolismo relacionado à escleroterapia são escassos na literatura. O objetivo do trabalho é alertar para essa possibilidade, valorizando as queixas de dor e edema após a escleroterapia. Havendo suspeita clínica, o duplex scan deve ser realizado.

ABSTRACT

INTRODUCTION: An alternative technique for kidney transplantation is presented for patients in whom the use of pelvic vessels is precluded. PATIENTS AND METHODS: Of 482 cases of kidney or pancreas-kidney transplants, 4 were unsuited to heterotopic grafting, 1 due to multiple operations in the fossae and the 3 others due to extensive vascular occlusive disease. The patients were studied preoperatively by magnetic resonance angiography, which revealed extensive occlusive disease of the distal aorta and/or iliac vessels. RESULTS: The patients received kidneys from living related donors as a third or second transplant opportunity in the orthotopic position (2 cases). Gross dissection of the aorta revealed a thickened wall, impeding direct anastomoses between the recipient's arteries and the donated organ. After a termino-lateral Dacron graft to the aorta, all cases were stented for uretero-uretero anastomosis. Recovery with respect to the renal graft was uneventful for all cases. CONCLUSIONS: Alternative direct grafting from the aorta represents a viable and easy way to perform kidney transplants in patients unsuited to the heterotopic approach.

ABSTRACT

Objetivos: a via mais utilizada de acesso à aorta abdominal para correção da doença obstrutiva ou aneurismática é a transperitoneal,sendo que a retroperitoneal é muitas vezes apontada como uma viaque oferece menos complicações. O objetivo deste estudo é comparar as duas vias em termos de suas complicações precoces. Pacientes e métodos: para comparação da evolução precoce, foram estudados prospectivamente 84 pacientes submetidos à cirurgia de aneurisma de aorta abdominal (45 casos) e correção de doença obstrutiva aorto-ilíaca (39 casos). A via retroperitoneal foi utilizada em 41 pacientes, e a transperitoneal, em 43 pacientes.Resultados: a abordagem retroperitoneal acarretou menor necessidade de reposição de líquidos, menor tempo de entubação, retorno mais rápido da função intestinal, reinício de ingestão alimentar e deambulação mais precoce. Não houve diferença na reposição sanguínea e no tempo de internação. Conclusões: a via de acesso retroperitoneal apresenta vantagens relacionadas com a evolução precoce do paciente, podendo ser utilizada como rotina.

ABSTRACT

O seroma periprotético é uma das raras complicações dos enxertos vasculares sintáticos. Tem incidência entre 2 a 10 por mil reparos vasculares. E caracterizada como uma coleção líquida que circunda a prótese limitada por uma pseudocápsula.Relatamos o caso de uma paciente que tres meses depois de implante de uma prótese de Dacron em situação fêmoro-femoral cruzada desenvolveu abaulamento supra-púbico volumoso. Foi acompanhada ao longo de quatro anos, sendo finalmente operada, quando ocorreu a correção definitiva do problema...

ABSTRACT

A artéria carótida interna normalmente não tem ramos em sua porção cervical, sendo que variações desta peculiaridade são raras. A presença da artéria faríngea ascendente como ramo da artéria carótida interna decorre de alterações embriológicac. Inicialmente foi detectada em dissecção de cadáveres e, posteriormente, com oadvento da arteriografia, em indivíduos vivos.Tais variações anatômicas podem ser responsáveis por alterações hemodinâmicas vindo a participar da manutenção de fluxo cerebral do hemisfério cerebral.O caso relatado representa uma situação em que houve oclusão de artéria carótida interna por degeneração aterosclerótica, porém com preservação de fluxo cerebralatravés da artéria faríngea ascendente como ramo anômalo da artéria carótida interna...
