RESUMO
Chronic kidney disease is a worldwide public health problem, and end-stage renal disease requires dialysis. Most patients requiring renal replacement therapy have to undergo hemodialysis. Therefore, vascular access is extremely important for the dialysis population, directly affecting the quality of life and the morbidity and mortality of this patient population. Since making, managing and salvaging of vascular accesses falls within the purview of the vascular surgeon, developing guideline to help specialists better manage vascular accesses for hemodialysis if of great importance. Thus, the objective of this guideline is to present a set of recommendations to guide decisions involved in the referral, evaluation, choice, surveillance and management of complications of vascular accesses for hemodialysis.
A doença renal crônica é um problema de saúde pública global e em seu estágio terminal está associada à necessidade de terapia dialítica. A grande maioria dos pacientes que necessitam realizar a terapia renal substitutiva, a fazem através da hemodiálise. Portanto, o acesso vascular é de extrema importância para a população dialítica, implicando diretamente na qualidade de vida e na morbimortalidade deste grupo de pacientes. Sendo a confecção, gerenciamento e resgate dos acessos vasculares uma das áreas de atuação do cirurgião vascular, é de grande importância a elaboração de uma diretriz que oriente o especialista no manejo mais adequado do acesso vascular para hemodiálise. Assim, o objetivo desta diretriz é apresentar um conjunto de recomendações para guiar as decisões na referenciação, avaliação, escolha, vigilância e gestão das complicações do acesso vascular para hemodiálise.
RESUMO
BACKGROUND: Vascular malformations are rare diseases and treatment remains controversial. Sclerotherapy is accepted as a minimally invasive treatment with good results; however, some patients do not report good response to sclerotherapy, and it is not clear which variables influence treatment outcome, preventing optimal patient selection. We hypothesized that large diameter lesions have reduced efficacy and satisfaction with sclerotherapy. Therefore, we prospectively evaluated the clinical response of low-flow vascular malformations treated with 1% polidocanol foam sclerotherapy and determined the correlation of symptom improvement with clinical variables. METHODS: Prospective cohort study of patients with symptomatic low flow vascular malformations treated at the Hospital das Clínicas between December 2016 and November 2018. Lesions were classified according to location, extension, diameter, type of vessels, margins, and symptoms. Sclerotherapy was performed by direct injection of 1% polidocanol foam, with a maximum volume of 10 ml per session. Symptom improvement was evaluated using the visual analog scale and patient-reported quality of life was assessed by the Short-form 6 dimensions (SF-6D) questionnaire. Follow-up was performed every 3 months after treatment. RESULTS: Forty lesions were treated in 38 patients, with 19 women and 19 men; median age was 20.5 years (range 4 months to 63 years). Most lesions (80%) were venous, and most commonly in the lower limbs (47.5%); 27.5% were superficial, 35% were deep, and 37.5% affected both compartments. The most common clinical presentations were deformity (95%), pain (78%), and functional limitation (58%); deep compartment lesions were more associated with functional limitation (69% vs. 27%; P = 0.030). Fifty-three per cent of lesions were >10 cm and were associated with increased numbers of psychosocial symptoms (P = 0.038). Two-hundred and forty-two sessions of sclerotherapy were performed, with 6 mean treatments per lesion (range 1-15). The mean follow-up time was 23 months (range 2-23 months). The most common complications were pain and local edema, without any major complications; some patients reported symptom recurrence (15% pain, 10% deformity, and 12% functional limitation). Sclerotherapy was associated with significant improvement of all symptoms (P < 0.001). However, lesions >10 cm were associated with poor improvement in deformity (P = 0.003). Quality of life improved for most patients (60%) and treatment satisfaction was high (82%). CONCLUSIONS: Treatment of low-flow vascular malformations with 1% polidocanol foam is safe and effective; sclerotherapy improves symptoms and quality of life. Large diameter lesions (>10 cm) are associated with increased treatment failure. A small percentage of patients reported recurrent symptoms and require other modalities for successful treatment.

INTRODUCTION: Evaluation of limb hemodynamics using the ankle-brachial index (ABI) may be difficult due to skin lesions, extensive necrosis, and obesity, such as commonly present in patients with diabetes with chronic limb-threatening ischemia (CLTI). We hypothesized that the pedal acceleration time (PAT) correlates with ABI and Wound, Ischemia, and foot Infection (WIfI) scores in patients with diabetes to serve as a new modality to accurately stage CLTI. METHODS: A single-center, cross-sectional study included patients with and without diabetes > 18 years with CLTI. Limbs were categorized in three grades of ischemia based on the ABI (ABI < 0.8, < 0.6, and < 0.4) and in two classes based on WIfI stages of amputation risk. Receiver operator characteristic (ROC) curves were used to determine PAT sensitivity, specificity, and accuracy to predict lower-limb ischemia. RESULTS: A total of 141 patients (67 nondiabetic and 74 diabetic) and 198 lower limbs (94 nondiabetic and 104 diabetic) met the inclusion criteria. In patients without diabetes, the accuracy of PAT for detecting an ABI < 0.8 was 85%; for detecting an ABI < 0.6 was 85%; and for detecting an ABI < 0.4 was 87%. In patients with diabetes, the accuracy of PAT in detecting an ABI < 0.8 was 91%; for detecting an ABI < 0.6 was 79%; and for detecting an ABI < 0.4 was 88%. In patients without diabetes, the accuracy for detecting WIfI stages of moderate and high amputation risk was 77% and for patients with diabetes was also 77%. CONCLUSIONS: PAT shows high correlation with the ABI as well as with the WIfI stages of amputation risk and the grades of ischemia, with high accuracy.

RESUMO
INTRODUCTION: perioperative risk assessment is essential to mitigate surgical complications, which suggests individual and collective interest since the number of surgical procedures in Brazil has been expanding steadily. The aim of this study was to summarize and detail the main calculators, indexes and scores regarding perioperative pulmonary, renal, hepatobiliary, hematological and surgical site infection risks for general non-cardiac surgeries, which are dispersed in the literature. METHOD: a narrative review was performed based on manuscripts in English and Portuguese found in the electronic databases Pubmed/MEDLINE and EMBASE. RESULTS: the review included 11 tools related to the systems covered, for which the application method and its limitations are detailed. CONCLUSION: the non-cardiovascular perioperative risk estimation tools are beneficial when disturbances are identified in the preoperative clinical examination that justify a possible increased risk to the affected system, so the use of these tools provides palpable values to aid in the judgment of surgical risk and benefit as well as it identifies factors amenable to intervention to improve outcomes.

The number of surgical procedures in the world is large and in Brazil it has been expressing a growth trend higher than the population growth. In this context, perioperative risk assessment safeguards the optimization of the outcomes sought by the procedures. For this evaluation, anamnesis and physical examination constitute an irreplaceable initial stage which may or may not be followed by complementary exams, interventions for clinical stabilization and application of risk estimation tools. The use of these tools can be very useful in order to obtain objective data for decision making by weighing surgical risk and benefit. Global and cardiovascular risk assessments are of greatest interest in the preoperative period, however information about their methods is scattered in the literature. Some tools such as the American Society of Anesthesiologists Physical Status (ASA PS) and the Revised Cardiac Risk Index (RCRI) are more widely known, while others are less known but can provide valuable information. Here, the main indices, scores and calculators that address general and cardiovascular perioperative risk were detailed.

RESUMO O número de procedimentos cirúrgicos no mundo é amplo e no Brasil vem expressando tendência de crescimento superior ao crescimento populacional. Nesse contexto, a avaliação de risco perioperatório resguarda a otimização dos desfechos buscados pelos procedimentos. Para a realização dessa avaliação, a anamnese e exame físico constituem etapa inicial insubstituível, a qual pode ou não ser seguida de exames complementares, intervenções para estabilização clínica e aplicação de ferramentas de estimativa de risco. A utilização destas ferramentas pode ser bastante útil a fim de se obter um dado objetivo para a tomada de decisão pesando-se risco e benefício cirúrgico. As avaliações de risco global e cardiovascular são as de maior interesse no pré-operatório, entretanto informações sobre seus métodos encontram-se dispersas na literatura. Algumas ferramentas como o American Society of Anesthesiologists Physical Status (ASA PS) e Índice de Risco Cardíaco Revisado (RCRI) são mais amplamente conhecidos, enquanto outros são menos conhecidos em nosso meio mas podem fornecer informações valiosas. Aqui detalhou-se os principais índices, escores e calculadoras que abordam risco perioperatório geral e cardiovascular.

RESUMO
BACKGROUND: Chronic kidney disease is a major public health problem. Hemodialysis is the most common renal replacement therapy. Arteriovenous fistulas (AVF) are a possible access option, but early failure rates remain high. OBJECTIVES: to investigate the value of intraoperative vascular Doppler ultrasound for predicting early AVF patency. METHODS: Prospective observational study. Consecutive patients undergoing AVF were assessed with vascular Doppler ultrasonography intraoperatively and on days 1, 7, 30, and 60. Patients were divided into groups according to presence or absence of primary and secondary patency. Blood flow (BF) and peak systolic velocity (PSV) were compared. ROC curves were plotted and used to define the PSV and BF values that yielded greatest sensitivity (Sens) and specificity (Spec). RESULTS: 47 patients met the inclusion criteria and were analyzed. Higher intraoperative PSV and BF values were observed in patients who had primary and secondary patency than in patients with access failure. The values with greatest sensitivity and specificity for predicting 30-day primary patency were 106 cm/s for venous PSV (Sens: 75% and Spec: 71.4%) and 290.5 ml/min for arterial blood flow (Sens: 80.6% and Spec 85.7%). Values for 30-day secondary patency were 106 cm/s for arterial PSV (Sens: 72.7%, Spec: 100%) and 230 ml/min for venous blood flow (Sens: 86.4%, Spec100%). Values for 60-day primary patency were 106 cm/s for venous PSV (Sens: 74.4%, Spec: 62.5%) and 290.5 ml/min for arterial blood flow (Sens: 80%, Spec: 75%). CONCLUSIONS: Peak systolic velocity and blood flow measured using intraoperative vascular Doppler ultrasound can predict early patency of hemodialysis arteriovenous fistulas.
RESUMO
Resumo Contexto A insuficiência renal crônica é um problema de saúde pública mundial. A hemodiálise é a principal terapia renal substitutiva. As fístulas arteriovenosas (FAV) são uma possível escolha, mas apresentam altas taxas de falência. Objetivos Este estudo tem como objetivo avaliar a relação entre as variáveis hemodinâmicas ao ultrassom vascular com Doppler no intraoperatório e a perviedade precoce da FAV para hemodiálise. Métodos Tratou-se de um estudo prospectivo observacional. Os pacientes consecutivos foram submetidos a FAV com ultrassonografia vascular com Doppler em intraoperatório nos dias 1, 7, 30 e 60. Eles foram divididos em grupos quanto à presença ou não de perviedade primária e secundária, e o volume de fluxo (VF) e a velocidade de pico sistólico (VPS) foram comparados. Foram realizadas curvas receiver operating characteristic (ROC), com definição de valores de VPS e VF com sensibilidade (S) e especificidade (E). Resultados Foram analisados 47 pacientes, os quais preencheram os critérios de inclusão. Os valores de VPS e VF intraoperatório foram maiores nos pacientes com perviedade primária e secundária comparados àqueles com falência. Os seguintes valores apresentaram maiores sensibilidade e especificidade para predizer perviedade primária aos 30 dias: 106 cm/s para VPS venoso, S: 75%, E: 71,4%; e 290,5 mL/min para VF arterial, S: 80,6%, E: 85,7%. Para perviedade secundária aos 30 dias, foram observados: 106 cm/s para VPS arterial, S: 72,7%, E: 100%; e 230 mL/min para VF venoso, com S: 86,4%, E: 100%. Para a perviedade primária no 60º dia, foram observados: 106 cm/s para VPS venoso, S: 74,4%, E: 62,5%; e 290,5 mL/min para VF arterial, S: 80%, E: 75%. Conclusões A velocidade de pico sistólico e o VF ao ultrassom vascular com Doppler intraoperatório são preditores de perviedade precoce na FAV para hemodiálise.

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
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.
