Abstract Background Atrial fibrillation (AF) is the most common arrhythmia in patients with end-stage renal disease (ESRD). The coexistence of high thromboembolic and hemorrhagic risks, added to the lack of strong scientific evidence on the safety of anticoagulants in the setting of renal failure, makes this a clinically challenging situation. Objectives To describe the clinical-demographic profile and prevalence of AF in the population with ESRD undergoing dialysis. Secondary objectives include the assessment of thromboembolic (CHA2DS2VASC) and bleeding (HASBLED) risk scores. Methods Cross-sectional analytical-descriptive study, carried out between January and March 2020. Patients with ESRD were evaluated by means of a medical history questionnaire, physical examination, and 12-lead electrocardiogram. A chi-square (χ2) association test was applied to calculate association between clinical variables and AF, with a significance level of α = 0.05. Results This study evaluated 295 patients, most of whom were men (170), elderly (63, IQR 53-71), current smokers (130), with associated cardio-endocrine comorbidities. The prevalence of AF was 6.7% (20). Heart failure (HF) (χ2=15.417; p<0.001), age of 65 years or older (χ2=14.584; p<0.001), and anticoagulation (χ2=5.715; p<0.01) were associated with AF. The median CHA2DS2VASC and HASBLED was 4 and 3, respectively. Eight patients were taking warfarin and five were receiving apixaban. Conclusion The prevalence of AF in this study is similar to that reported in other published articles on the subject, and patients were at high risk for cardiovascular outcomes. Non-anticoagulation strategy was commonly adopted due to controversies in the literature as well as the absence of published randomized clinical trials. (AF endstage end stage ESRD. .

Abstract The Brazilian Society of Angiology and Vascular Surgery, through the Guidelines Project, presents new Abdominal Aortic Aneurysm Guidelines, on the subject of care for abdominal aortic aneurysm patients. Its development prioritized descriptive guidelines, using the EMBASE, LILACS, and PubMed databases. References include randomized controlled trials, systematic reviews, meta-analyses, and cohort studies. Quality of evidence was evaluated by a pair of coordinators, aided by the RoB 2 Cochrane tool and the Newcastle Ottawa Scale forms. The subjects include juxtarenal aneurysms, infected aneurysms, and new therapeutic techniques, especially endovascular procedures. The current version of the guidelines include important recommendations for the primary topics involving diagnosis, treatment, and follow-up for abdominal aortic aneurysm patients, providing an objective guide for medical practice, based on scientific evidence and widely available throughout Brazil.

Resumo A Sociedade Brasileira de Angiologia e Cirurgia Vascular, por meio do projeto Diretrizes, apresenta as novas Diretrizes de Aorta Abdominal, referentes aos cuidados de pacientes com aneurisma de aorta abdominal. Para sua elaboração, foram priorizadas diretrizes descritivas, utilizando as bases EMBASE, LILACS e PubMed. As referências incluem ensaios clínicos randomizados, revisões sistemáticas, metanálises e estudos de coorte. A qualidade das evidências foi examinada por uma dupla de coordenadores, com auxílio da ferramenta RoB 2 da Colaboração Cochrane e dos formulários da Newcastle Ottawa Scale. Aneurismas justarrenais, infectados e novas técnicas terapêuticas, principalmente no âmbito endovascular, estão entre os temas estudados. A versão atual das Diretrizes apresenta importantes recomendações para os principais itens que envolvem o diagnóstico, tratamento e acompanhamento de pacientes com aneurisma de aorta abdominal, oferecendo um guia objetivo para prática médica, construído a partir de evidências científicas e amplamente acessível em todo o território nacional.

Abstract Coronary subclavian steal syndrome is an uncommon cause of angina in patients with a previous coronary artery bypass graft procedure. The patient had chest pain with the exertion of the left upper limb, difference in blood pressure between the left and right arm, occlusion at the ostium of the left subclavian artery. He underwent carotid subclavian bypass surgery that was successful in relieving symptoms. On the other hand, the patient had an embolic stroke related to the procedure and further assessment may be necessary.
