RESUMO

OBJECTIVE: Lower extremity varicose veins have a high prevalence and can be associated with significant morbidity in their more advanced presentations; overweight patients tend to present with more severe clinical symptoms and conventional surgical treatment remains challenging. Although the advent of ultrasound-guided foam sclerotherapy (UGFS) increased the treatment options for these patients, the need for elastic compression after UGFS remains controversial. METHODS: Overweight patients with lower extremity varicose veins secondary to great saphenous vein reflux were treated with UGFS and then randomized to use or no use of a 3-week treatment of elastic compression stockings. Follow-up was performed by clinical evaluation and duplex ultrasound examination. The primary outcome measure was the absence of venous reflux in the great saphenous vein. RESULTS: One hundred thirty-five lower limbs were treated; 72 limbs were randomized to elastic compression and 63 limbs to the control group. There were no statistically significant differences in the number of procedures (P = .64) or the mean foam volume per procedure (P = .27) between groups. There was no difference in the reflux rate at either 3 weeks (26% vs 35%; P = .16) or 3 months (25% vs 21%; P = .85). Major complications were venous deep thrombosis (n = 2), neurologic event (n = 1), and ischemic ulceration (n = 1); the overall rate was 3% in both groups-2 of 62 in control patients and 2 of 69 in compression patients (P = .45). Venous diameter reduction was noted in both groups during treatment (P < .05) but with greater decrease in greater saphenous vein diameter in patients treated with compression. CONCLUSIONS: Elastic compression stockings for 3 consecutive weeks after UGFS in overweight patients did not decrease great saphenous vein reflux, need for repeat procedures, or the volume of foam injected. However, UGFS was associated with a greater and uniform reduction in saphenous vein diameter at all times after the procedure.

RESUMO

Background: There is currently a worldwide effort to increase the options for autogenous hemodialysis access. Objectives: To evaluate patency and complications of brachial vein transposition compared to other autogenous hemodialysis accesses. Methods: A retrospective evaluation of 43 patients and 45 procedures. Patients who did not have adequate superficial veins according to duplex scanning were allocated to brachial vein transposition. The sample was thus divided in two groups, as follows: A: brachial vein transposition n=10 and B: other autogenous accesses n=35. Results: There were no statistical differences between the two groups in terms of age diabetes, systemic arterial hypertension, dyslipidemias, arteriopathies, neoplasms, kidney disease stage, donor artery diameter, recipient vein diameter, systolic blood pressure in the operated limb, postoperative ischemia, hematoma, or infection. There were no statistical differences in terms of patency on day 7: A 80% vs. B 90% p=0.6, on day 30: A 80% vs. B 86% p=0.6, or on day 60: A 60% vs. B 80% p=0.22. There were statistical differences between the groups for number of previous fistulae A 1.0 ± 0.44 vs. B 0.6 ± 0.3 p = 0.04 and upper limb edema A: 20% x B 0% p = 0.04. A vein with diameter of less than 3 mm was associated with an increased risk of early occlusion (RR = 8 p = 0.0125). During the study period there were no procedures using grafts. Conclusions: Transposition of brachial vein is an alternative to arteriovenous graft.

RESUMO

BACKGROUND: Arterial stiffness analysis has been done to classify cardiovascular risk. The aim of this article is to analyze whether the group of patients with chronic limb-threatening ischemia (CLTI) has higher arterial stiffness indices than controls. The secondary objectives are to assess whether patients with advanced stages of Wound, Ischemia, and foot Infection (WIfI) classification have high levels of arterial stiffness, through multiple linear regressions to analyze whether the ankle-brachial index (ABI) and other variables are predictive of arterial stiffness. METHODS: We conducted a cross-sectional study with 66 patients with CLTI and 66 age- and sex-matched controls using brachial artery oscillometry. Hemodynamic and arterial stiffness measurements, clinical characteristics, laboratory data, and stages of WIfI classification were compared between the groups CLTI and controls. Through multiple linear regression, we identified predictors of pulse wave velocity (PWV) and augmentation index normalized to 75 beats/min (AIx@75). RESULTS: Patients with CLTI had PWV (11.8 ± 1.6 m/sec vs. 10.0 ± 1.8 m/sec, P < 0.01) and AIx@75 (29.2 ± 9.8% vs.18. ± 10.35%, P < 0.01) higher than controls. In the multiple regression model, there was influence of age (ß = 0.17, P < 0.01), antiplatelet therapy (ß = -0.15, P = 0.04), peripheral systolic pressure (ß = 0.03, P < 0.01), and clustered WIfI stages 3 and 4 (ß = 0.17, P = 0.02) of benefit of revascularization on PWV. Multiple regression analysis identified diabetes (ß = 7.51, P < 0.01) and the degree of ischemia measured by ABI (ß = -23.89, P < 0.01) as predictors of elevated AIx@75. WIfI stages 3 and 4 of estimate risk of amputation at 1 year predicts a high AIx@75 (ß = 9.77, P < 0.001) compared with stages 1 and 2. CONCLUSIONS: The degree of ischemia in CLTI patients determined by the ABI is associated with elevated arterial stiffness as measured by the AIx@75. Advanced WIfI stages were predictors of elevated PWV and AIx@75.

RESUMO

A lesão no pé de pacientes com diabetes é um importante problema de saúde pública que frequentemente está associado a amputações em membros inferiores e mortalidade nessa população. Objetivos: Investigar os fatores de risco associados a mortalidade em pacientes com pé diabético infectado submetidos a amputação maior. Métodos: Estudo observacional, retrospectivo e caso-controle. Amostra composta por 78 pacientes com pé diabético e úlcera infectada submetidos a amputação maior em um serviço de cirurgia vascular em um hospital universitário no período de 5 anos. Resultados: A média de idade da amostra estudada foi de 63,8 ± 10,5 anos, com 54 (69,2%) pacientes do sexo masculino, com creatinina sérica média de 2,49 ± 2,4 mg/dL e hemoglobina sérica média de 7,36 ± 1,7 g/dL. Houve 47,4% de reinternação. Foi realizada amputação transtibial em 59,0% e transfemoral em 39,7% da amostra estudada. Nesta amostra, 87,2% dos pacientes apresentaram cultura positiva, predominantemente monomicrobiana (67,9%), e 30,8% presentaram infecção hospitalar da úlcera. Os gêneros de bactérias mais frequentes foram Acinetobacter spp. (24,4%), Morganella spp. (24,4%) e Proteus spp. (23,1%). Nenhum gênero bacteriano foi identificado como fator de risco para óbito. O nível de creatinina ≥ 1,3 mg/dL (OR 17,8; IC 2,1-150) e a amputação transfemoral (OR 4,5; C: 1,3-15,7) foram fatores de risco para o óbito. Conclusões: Os níveis séricos de creatinina ≥ 1,3 mg/dL e amputação transfemoral foram fatores de risco para óbito

RESUMO

OBJECTIVE: The disease of the aortic arch is traditionally approached by open surgical repair requiring cardiopulmonary bypass and circulatory arrest. This study performed a retrospective analysis comparing outcomes through primary hybrid patients submitted to aortic arch surgery without cardiopulmonary bypass with patients submitted to conventional open surgery. METHODS: 25 patients submitted to the aortic arch surgery were selected in the period 2003-2012 at the Madre Teresa Hospital in the city of Belo Horizonte, Brazil; 13 of these underwent hybrid technique without cardiopulmonary bypass and 12 underwent conventional open surgery. RESULTS: The mortality rate for the hybrid group was 23% and for the conventional surgery group was 17% (P=0.248). The postoperative complication rate was also similar in both groups, with no significant difference. CONCLUSION: Both techniques proved to be similar in mortality and morbidity. However, due to the small sample, more analytical studies with larger samples and long-term follow-up are needed to clarify this issue.

RESUMO

Extracranial cerebrovascular disease is one of the most important causes of death and disability worldwide and its treatment is based on clinical and surgical strategies, the latter being performed by conventional or endovascular techniques. The management of stenosis of the carotid bifurcation is mainly aimed at preventing stroke and has been the subject of extensive investigation. The role of clinical treatment has been re-emphasized, but carotid endarterectomy remains the first-line treatment for symptomatic patients with 50% to 99% stenosis and for asymptomatic patients with 60% to 99% stenosis. Stent angioplasty is reserved for symptomatic patients with stenosis of 50% to 99% and at high risk for open surgery due to anatomical or clinical reasons. Currently, the endovascular procedure is not recommended for asymptomatic patients who are able to undergo conventional surgical treatment. Brazil presents a trend similar to that of other countries in North America and Europe, keeping endarterectomy as the main indication for the treatment of carotid stenosis and reserving the endovascular procedure for cases in which there are contraindications for the first intervention. However, we must improve our results by reducing complications, notably the overall mortality rate.

RESUMO

Objective: to evaluate whether bacterial genus is a risk factor for major amputation in patients with diabetic foot and infected ulcer. Methods: we conducted a case-control, observational study of 189 patients with infected ulcers in diabetic feet admitted to the Vascular Surgery Service of the Risoleta Tolentino Neves Hospital, from January 2007 to December 2012. The bacteriological evaluation was performed in deep tissue cultures from the lesions and amputation was considered major when performed above the foot'smiddle tarsus. Results: the patients'mean age was 61.9±12.7 years; 122 (64.6%) were men. The cultures were positive in 86.8%, being monomicrobial in 72% of the cases. In patients with major amputation, Acinetobacter spp. (24.4%), Morganella spp. (24.4%), Proteus spp. (23.1%) and Enterococcus spp. (19.2%) were the most frequent types of bacteria. The most commonly isolated species were Acinetobacter baumannii, Morganella morganii, Pseudomonas aeruginosa and Proteus mirabilis. As predictors of major amputation, we identified the isolation of the generaAcinetobacter spp. and Klebsiella spp., serum creatinine ≥1.3mg/dl and hemoglobin <11g/dl. Conclusion: the bacterial genera Acinetobacter spp. and Klebsiella spp. identified in infected ulcers of patients with diabetic foot were associated with a higher incidence of major amputation.

RESUMO

RESUMO A doença vascular cerebral extracraniana é uma das mais importantes causas de morte e de incapacidade em todo o mundo e seu tratamento se baseia em estratégias clínica e cirúrgica, sendo que esta última pode ser feita pelas técnicas convencional ou endovascular. O manejo da estenose da bifurcação carotídea visa principalmente a prevenir o acidente vascular cerebral e tem sido objeto de extensa investigação. O papel do tratamento clínico tem sido re-enfatizado, mas a endarterectomia de carótida permanece como o tratamento de primeira linha para pacientes sintomáticos com estenose de 50% a 99% e, para pacientes assintomáticos, com estenose de 60% a 99%. A angioplastia com stent é reservada para pacientes sintomáticos, com estenose de 50% a 99% e com risco elevado para a cirurgia aberta, por motivos anatômicos ou clínicos. Atualmente, o procedimento endovascular não é recomendado para pacientes assintomáticos que tenham condições de serem submetidos ao tratamento cirúrgico convencional. O Brasil apresenta tendência semelhante à de outros países da América do Norte e Europa, observando a manutenção da endarterectomia como a principal indicação para o tratamento da estenose carotídea e reservando o procedimento endovascular para casos em que há contraindicações para a primeira intervenção. Todavia, temos de melhorar os nossos resultados, reduzindo as complicações, notadamente a taxa de mortalidade geral.

RESUMO

BACKGROUND: Periodontitis has been associated with a greater risk for atherosclerotic cardiovascular disease (ACD). Endothelial dysfunction (ED) is a parameter of early ACD, and its association with periodontitis has rarely been investigated to date. The objective of this study is to evaluate the association between periodontitis and ED by means of periodontal clinical parameters and salivary markers interleukin (IL)-1ß, tumor necrosis factor (TNF)-α, nitric oxide (NO), and matrix metalloproteinase (MMP)-2 and tissue inhibitor of metalloproteinases (TIMP)-2 complex. METHODS: Forty-seven individuals were divided into two groups: 1) 24 individuals with chronic periodontitis (CP); and 2) 23 individuals without CP. Periodontal examinations of bleeding on probing (BOP), probing depth (PD), and clinical attachment level (CAL) were performed. ED was evaluated by means of flow-mediated dilatation (FMD) of the brachial artery. Salivary concentrations of IL-1ß, TNF-α, and MMP-2/TIMP-2 complex were assessed using enzyme-linked immunosorbent assay. NO determination was based on the reaction of Griess. RESULTS: Individuals with CP presented higher occurrence of ED than individuals without CP (P = 0.03 after reactive hyperemia; P = 0.05 after sublingual nitrate). A significant association among the production of MMP-2/TIMP-2 complex with the presence of CP (P = 0.008) and periodontal parameters PD, CAL, and BOP was identified. Concentration of salivary markers IL-1ß, TNF-α, and NO was similar in individuals with and without CP. A significant positive correlation between NO and ED was also identified. CONCLUSIONS: Periodontitis was positively associated with ED, expressed by a smaller percentage of FMD of the brachial artery and higher salivary levels of MMP-2/TIMP-2 complex. Additionally, salivary levels of NO were significantly associated with better functioning of the vascular endothelium.

RESUMO

INTRODUCTION: Foot ulcer is also a clinical marker for limb amputation and for death in diabetic patients. The purpose of this study was to determine amputation and mortality rates and its associated factors in patients with diabetic foot ulcerations in a tertiary hospital in Brazil. METHODS: Retrospective medical records from 654 diabetic foot patients were reviewed. The risk factors were determined using the conditional logistic regression model analysis. RESULTS: The mean patient age was 63.1 years (SD 12.20). Peripheral arterial disease was present in 160 patients (24.5%). Major amputations were performed in 135 (21%). The in-hospital mortality rate was 12% and the mortality rate of the amputees was 22.2%. The lowest hemoglobin level, the median value was 9.50g/dL, (4.0-17.0). Anemia was detected in 89.6% of patients submitted to amputation and in 82,1% of those who died. Hemoglobin <11g/dL was the most significant risk factor for major amputation (odds ratio 5.57, p<0.0001). The presence of peripheral arterial disease and old age were also a risk for major amputation (odds ratio 1.84, p=0.007 and 1.02, p=0.028, respectively). Factors associated with increased risk for death were hemoglobin <11g/dL (odds ratio 4.04, p<0.001), major amputation (1.79, p=0.03) and old age (1.05, p<0,001). CONCLUSIONS: Diabetic foot ulcer is associated with high amputation and mortality rates. Old age, peripheral arterial disease and low hemoglobin level are risk factor for major amputation. Old age, major amputation and low hemoglobin level are risk factors for death.

RESUMO

The implant indication of cardiac electronic devices continues to expand; therefore, we have observed increasing complications related to their removal. We describe the case of a patient who presented with prolonged bloodstream infection after having undergone removal of a pacemaker. After extensive workup for fever of unknown origin and antibiotic therapy without any improvement, it was possible to demonstrate a foreign body in the right subclavian vein and superior vena cava corresponding to the distal part of the right ventricular lead. Endovascular removal of the foreign body and prolonged antibiotic administration was followed by complete resolution of the clinical picture. We ascribed the difficulty in diagnosing the source of the infection especially to the lack of local manifestations.

RESUMO

BACKGROUND: There is a knowledge gap with relation to the true incidence of deep vein thrombosis among patients undergoing vascular surgery procedures in Brazil. This study is designed to support the implementation of a surveillance system to control the quality of venous thromboembolism prophylaxis in our country. Investigations in specific institutions have determined the true incidence of deep vein thrombosis and identified risk groups, to enable measures to be taken to ensure adequate prophylaxis and treatment to prevent the condition.OBJECTIVE: To study the incidence of deep venous thrombosis in patients admitted to hospital for non-venous vascular surgery procedures and stratify them into risk groups.METHOD: This was a cross-sectional observational study that evaluated 202 patients from a university hospital vascular surgery clinic between March 2011 and July 2012. The incidence of deep venous thrombosis was determined using vascular ultrasound examinations and the Caprini scale.RESULTS: The mean incidence of deep venous thrombosis in vascular surgery patients was 8.5%. The frequency distribution of patients by venous thromboembolism risk groups was as follows: 8.4% were considered low risk, 17.3% moderate risk, 29.7% high risk and 44.6% were classified as very high risk.CONCLUSION: The incidence of deep venous thrombosis in vascular surgery patients was 8.5%, which is similar to figures reported in the international literature. Most vascular surgery patients were stratified into the high and very high risk for deep venous thrombosis groups.


CONTEXTO: Há lacuna de conhecimento sobre a real incidência de trombose venosa profunda nos pacientes submetidos a procedimentos cirúrgicos vasculares no Brasil. A atual pesquisa pretende corroborar a implementação de um sistema de vigilância e controle sobre a qualidade de profilaxia de tromboembolismo venoso em nosso meio. As investigações, em cada instituição, permitiriam revelar a incidência de trombose venosa profunda e a identificação dos grupos de risco, a fim de assumir medidas para obter profilaxia e terapêutica adequadas contra essa afecção.OBJETIVO: Estudar a incidência de trombose venosa profunda e estratificar os grupos de risco em pacientes internados, submetidos a procedimentos cirúrgicos vasculares não venosos.MÉTODO: Estudo observacional transversal, que avaliou 202 pacientes da Clínica de Cirurgia Vascular de um hospital universitário, entre março de 2011 e julho de 2012. A incidência de trombose venosa profunda foi determinada por meio de exame ultrassonográfico vascular, realizado em todos os pacientes. Os fatores de riscos de cada paciente foram estratificados de acordo com a escala Caprini.RESULTADOS: A média de incidência de trombose venosa profunda na Cirurgia Vascular foi de 8,5%. Em relação aos grupos de risco para tromboembolismo venoso, 8,4% foram considerados de baixo risco, 17,3% de moderado risco, 29,7% de alto risco e 44,6% de altíssimo risco.CONCLUSÃO: A incidência de trombose venosa profunda na Cirurgia Vascular foi de 8,5%, semelhante à registrada na literatura internacional. A maior parte dos pacientes cirúrgicos vasculares é estratificada em alto e altíssimo risco para trombose venosa profunda.

RESUMO

Introduction Individuals with chronic venous insufficiency (CVI) have muscle pump dysfunction and reduced functionality. However, studies are inconsistent in proving whether a particular test can assess muscle functional capacity. Therefore, the aim of this study was to evaluate whether the heel-rise test (HRT) is able to explain functional capacity in patients with CVI. Materials and methods Subjects with CVI aged between 20 and 59 years old were selected for this study. All participants were classified by means of the Clinical Anatomy Etiology Pathophysiology Classification of Chronic Venous Disease (CEAP). The HRT and the shuttle walk test (SWT) were performed. Descriptive statistics, Spearman correlation, linear models and regression variance analysis (one-way ANOVA) were used for data analysis. Significance was set at alpha ≤ 5%. Results 79 subjects were included in the study (38.79 ± 1.34 years). The HRT was able to explain functional capacity only in individuals aged between 50-59 years (R2 = 0.60, p = 0.0001). The heel-rise test was not sensitive to detect differences between the CEAP classes analyzed (p > 0.05). Conclusion The HRT was able to explain functional capacity in individuals aged between 50-59 years, and it can be applied in clinical practice for the functional evaluation of patients with CVI with mild severity in this age range. .


Introdução Indivíduos com insuficiência venosa crônica (IVC) podem apresentar disfunção da bomba muscular e redução de sua funcionalidade. Porém, estudos são inconsistentes em afirmar se um teste específico muscular pode avaliar a capacidade funcional. Sendo assim, o objetivo do presente estudo é avaliar se o teste da ponta do pé (TPP) é capaz de predizer a capacidade funcional em indivíduos com IVC. Materiais e métodos Foram selecionados para o estudo indivíduos com IVC com idade entre 20 e 59 anos. Os participantes foram classificados por meio da CEAP (Clinical Etiology Anatomy Pathophysiology Classification of Chronic Venous Desease). Foram realizados o TPP e o teste do deslocamento bidirecional progressivo (TDBP). Estatísticas descritivas, correlação de Spearman, modelos de regressão linear e análise de variância (ANOVA one-way) foram utilizados para a análise dos dados. Para significância estatística, foi usado alfa de 5%. Resultados Foram incluídos 79 indivíduos (38,79 ± 1,34 anos) no estudo. O TPP foi capaz de predizer a capacidade funcional somente em indivíduos de 50 a 59 anos (R2 = 0,60; p = 0,0001). O TPP não foi sensível em detectar diferenças entre as classes CEAP analisadas (p > 0,05). Conclusão O TPP foi capaz de explicar a capacidade funcional em indivíduos de 50 a 59 anos, podendo ser aplicado na prática clínica de forma válida para a avaliação funcional de pacientes com IVC de gravidade leve nessa faixa etária. .

RESUMO

OBJECTIVE: To study the stenosis of the carotid arteries in patients with symptomatic peripheral arterial disease. METHODS: we assessed 100 consecutive patients with symptomatic peripheral arterial disease in stages of intermittent claudication, rest pain or ulceration. Carotid stenosis was studied by echo-color-doppler, and considered significant when greater than or equal to 50%. We used univariate analysis to select potential predictors of carotid stenosis, later taken to multivariate analysis. RESULTS: The prevalence of carotid stenosis was 84%, being significant in 40% and severe in 17%. The age range was 43-89 years (mean 69.78). Regarding gender, 61% were male and 39% female. Half of the patients had claudication and half had critical ischemia. Regarding risk factors, 86% of patients had hypertension, 66% exposure to smoke, 47% diabetes, 65% dyslipidemia, 24% coronary artery disease, 16% renal failure and 60% had family history of cardiovascular disease. In seven patients, there was a history of ischemic cerebrovascular symptoms in the carotid territory. The presence of cerebrovascular symptoms was statistically significant in influencing the degree of stenosis in the carotid arteries (p = 0.02 at overall assessment and p = 0.05 in the subgroups of significant and non-significant stenoses). CONCLUSION: the study of the carotid arteries by duplex scan examination is of paramount importance in the evaluation of patients with symptomatic peripheral arterial disease, and should be systematically conducted in the study of such patients.

Objetivo: estudar estenose das artérias carótidas nos pacientes com doença arterial periférica sintomática. Métodos: avaliaram-se consecutivamente 100 portadores de doença arterial periférica sintomática, nos estágios de claudicação intermitente, dor em repouso ou lesão trófica. A estenose carotídea foi estudada pelo eco-color-doppler, sendo considerada significativa quando maior ou igual a 50%. A análise univariada foi utilizada para selecionar os potenciais preditores de estenose carotídea, levados posteriormente para análise multivariada. Resultados: a prevalência de estenose carotídea foi 84%, sendo significativa em 40% e acentuada em 17%. A idade variou de 43 a 89 anos (média de 69,78). Quanto ao sexo, 61% foram do sexo masculino e 39% do feminino. Metade dos pacientes da amostra era claudicante e metade tinha isquemia crítica. Quanto aos fatores de risco, 86% dos pacientes apresentaram hipertensão arterial sistêmica, 66% exposição ao fumo, 47% diabetes, 65% dislipidemia, 24% coronariopatia, 16% insuficiência renal e 60% história familiar positiva para doenças cardiovasculares. Em sete pacientes, havia história de alguma sintomatologia cérebro-vascular isquêmica no território carotídeo. A presença de sintomatologia cérebro-vascular mostrou-se estatisticamente significativa para influenciar o grau de estenose nas artérias carótidas (p=0,02 na avaliação global e p=0,05 nos subgrupos de estenoses significativas e não significativas). Conclusão: o estudo das artérias carótidas através do exame de duplex-scan é de suma importância na avaliação dos pacientes portadores de doença arterial periférica sintomática, devendo-se realizar o estudo de forma sistemática nos pacientes. .

RESUMO

OBJECTIVE: to determine the incidence of deep vein thrombosis and prophylaxis quality in hospitalized patients undergoing vascular and orthopedic surgical procedures. METHODS: we evaluated 296 patients, whose incidence of deep venous thrombosis was studied by vascular ultrasonography. Risk factors for venous thrombosis were stratified according the Caprini model. To assess the quality of prophylaxis we compared the adopted measures with the prophylaxis guidelines of the American College of Chest Physicians. RESULTS: the overall incidence of deep venous thrombosis was 7.5%. As for the risk groups, 10.8% were considered low risk, 14.9%moderate risk, 24.3% high risk and 50.5% very high risk. Prophylaxis of deep venous thrombosis was correct in 57.7%. In groups of high and very high risk, adequate prophylaxis rates were 72.2% and 71.6%, respectively. Excessive use of chemoprophylaxis was seen in 68.7% and 61.4% in the low and moderate-risk groups, respectively. CONCLUSION: although most patients are deemed to be at high and very high risk for deep vein thrombosis, deficiency in the application of prophylaxis persists in medical practice.
