Resumo: Las complicaciones cardiovasculares representan la principal causa de morbilidad y mortalidad en pacientes con enfermedad renal crónica, por lo que el objetivo de este artículo es demostrar la influencia de la permanencia de la fístula arteriovenosa sobre variables eco cardiográficamente mensuradas en el corazón izquierdo. Para ello, se definió un estudio multivariable, longitudinal, prospectivo y controlado de grupos independientes después de una intervención que incluyó 39 pacientes a los que se le cerró el angioacceso (grupo de estudio) y 42 que no fueron expuestos a la cirugía (grupo control). Ambos grupos exhibían trasplante renal funcionante. Los principales resultados surgenal comparar el predominio entre el grupo de estudio con el de control, la edad promedio; 45,6 y 44,1 años, el sexo masculino, 24 (60%) y 23 (53,5%) y el color de la piel blanca; 33 (82,5%) y 32 (74,4%). La etiología de la nefropatía originaria más frecuente fue la nefropatía vascular hipertensiva; 12 (30%) vs 14 (32,6%). Entre las manifestaciones clínicas, en el grupo de estudio se evidenció remisión de las palpitaciones y la disnea de esfuerzo. Respecto a la tensión arterial, para la sistólica oscilaba; de 123 ±13,4 a 120,5 ±9,2 vs de 125,6 ±8,4 a 128 ±8,3 mm Hg (p= 0,000), mientras la diastólica variaba de; 76,8 ±7,5 a 76,3 ±6,2 vs 78,6 ±4,9 a 82,4 ±3,9 mm Hg (p= 0,000). El hematocrito comportaba valores equivalentes; 0,43 ±0,06 y 0,45 ±0,06 vs 0,42 ±0,05 y 0,42 ±0,06 l/l (p= 0,035) y la creatinina sérica mostró descenso en los pacientes intervenidos de; 106,8 ± 26,2 hasta 99,8 ±23,9 µ Mol/l vs 114 ±27,8 a 120,3 ±31 µ Mol/l (p= 0,002). Las variables ecocardiográficas mensuradas comparativamente según la localización de los angioaccesos a nivel del codo izquierdo; diámetro del ventrículo izquierdo: 3,12 ±4,08 vs 1,48 ±3,46 mms (p=0,001), fracción de eyección del ventrículo izquierdo: 2,99 ±5,47 vs -1,98 ±6,23 % (p=0,018) y el volumen telediastólico: -23 ±33,41 vs 10,86 ±36,87 ml (p=0,006). El codo contralateral revelaba; para la fracción de eyección del ventrículo izquierdo: 3,32 ±3,42 vs -2,18 ±4,78 % (p=0,037) y para el gasto cardíaco: -1,29 ±0,88 vs -0,26 ±0,86 l/min (0,020). Las conclusiones demuestran que el cierre del angioacceso a pacientes con trasplante renal funcionante respecto a los no intervenidos, contribuye a la regresión de las alteraciones morfológicas y hemodinámicas constatadas por ecocardiografía transtorácica en el corazón izquierdo a nivel de las diferentes localizaciones de los accesos vasculares.

Cardiovascular complications represent the main cause of morbidity and mortality in patients with chronic renal disease, so the objective of this article is to demonstrate the influence of the patency of the arteriovenous fistula on echocardiographic variables measured in the left heart. For this, a multivariate study, longitudinal, prospective and controlled study of independent groups after an intervention that included 39 patients who had their angioaccess closed (study group) and 42 who were not exposed to surgery (control group). Both groups exhibited functional kidney transplantation. The main results emerge when comparing the prevalence between the study group and the control group, the average age; 45.6 and 44.1 years, the male sex, 24 (60%) and 23 (53.5%) and the white skin color; 33 (82.5%) and 32 (74.4%). The most frequent etiology of the original nephropathy was hypertensive vascular nephropathy; 12 (30%) vs 14 (32.6%). Among the clinical manifestations, remission of palpitations and dyspnea on exertion were evidenced in the study group. With regard to blood pressure, for the systolic it ranged from 123 ±13.4 to 120.5 ±9.2 vs. 125.6 ±8.4 to 128 ±8.3 mmHg (p= 0.000), while the diastolic varied from; 76.8 ±7.5 to 76.3 ±6.2 vs. 78.6 ±4.9 to 82.4 ±3.9 mmHg (p= 0.000). The hematocrit had equivalent values; 0.43 ±0.06 and 0.45 ±0.06 vs 0.42 ±0.05 and 0.42 ±0.06 l/l (p= 0.035) and the serum creatinine showed decrease in the operated patients from; 106.8 ±26.2 to 99.8 ±23.9 µMol/l vs 114 ±27.8 to 120.3 ±31 µMol/l (p= 0.002). The echocardiographic variables measured comparatively according to the location of the angioaccesses at the left elbow level; diameter of the left ventricle: 3.12 ±4.08 vs 1.48 ±3.46 mms (p=0.001), ejection fraction of the left ventricle: 2.99 ±5.47 vs -1.98 ±6.23 % (p=0.018) and the telediasolic volume: -23 ±33.41 vs 10.86 ±36.87 ml (p=0.006). The contralateral elbow revealed; for the left ventricular ejection fraction: 3.32 ±3.42 vs -2.18 ±4.78 % (p=0.037) and for cardiac output: -1.29 ±0.88 vs -0.26 ±0.86 l/min (0.020). The conclusions show that the our study has shown that closing the angioaccess to patients with functioning renal transplants with respect to those not operated, contributes to the regression of morphological and hemodynamic alterations observed by transthoracic echocardiography in the left heart at the different locations of the vascular accesses.

Título: Hemobilia como causa infrecuente y grave de hemorragia digestiva alta / Hemobilia as a rare and serious cause of upper gastrointestinal bleeding
Fonte: Rev. cuba. med;60(2):e1592
Idioma: es.
Resumo: Introducción: La hemobilia es por definición una causa de hemorragia digestiva alta, donde existe una comunicación de la vía biliar en cualquiera de sus segmentos con vasos sanguíneos que desembocan a través de la ampolla de Vater. Su presentación es infrecuente y no sospechada en la práctica clínica diaria de gastroenterólogos, cirujanos, hepatólogos, clínicos e intensivistas, con un difícil manejo diagnóstico-terapéutico y una elevada morbi-mortalidad. Objetivo: Describir tres casos de pacientes con diagnóstico de hemobilia. Desarrollo: Se presentan tres casos con hemobilia que tuvieron una elevada mortalidad y con diferente etiología; en el primer caso por trombosis de la arteria hepática postrasplante hepático, el segundo secundario a un colangiocarcinoma de la unión hepatocística y el tercero con diagnóstico de un aneurisma de la arteria hepática derecha confirmado y parcialmente tratado por angiotomografía, posteriormente intervenido quirúrgicamente y único sobreviviente. Conclusiones: Resultaron tres casos con hemobilia de diferentes causas, con una elevada mortalidad por la intensidad de la hemorragia digestiva alta y las comorbilidades asociadas, además de señalar que ninguno de ellos presentó la tríada clásica reportada por Quincke(AU)

Introduction: Hemobilia is, by definition, a cause of upper gastrointestinal bleeding, where there is a communication of the bile duct in any of its segments with blood vessels that flow through the ampulla of Vater. It is rare and it is not suspected in the daily clinical practice of gastroenterologists, surgeons, hepatologists, clinicians and intensivists, hence the diagnostic-therapeutic management is difficult and it has high morbidity and mortality. Objective: To report three cases of patients with a diagnosis of hemobilia. Case report: We report three cases of hemobilia of high mortality and different etiology. The first case had post-liver transplantation hepatic artery thrombosis, the second had asecondary cholangiocarcinoma of the hepatocystic junction and the third had diagnosis of confirmed right hepatic artery aneurysm partially treated by CT angiography, subsequently operated on and the only survivor. Conclusions: These three hemobilia cases had different causes, and high mortality due to the intensity of the upper gastrointestinal bleeding and the associated comorbidities, in addition to noting that none of them exhibited the classic triad reported by Quincke(AU)

Resumo: Introducción. Las malformaciones vasculares cerebrales de alto flujo son poco comunes en la edad pediátrica. El objetivo del trabajo es diferenciar y agrupar estas enfermedades según edad de debut, manifestaciones clínicas y angioarquitectura.Población y método. Se realizó un estudio retrospectivo y observacional. Se analizaron las historias clínicas, los estudios por imágenes y los protocolos de procedimientos de pacientes del Hospital J. P. Garrahan con diagnóstico de malformaciones vasculares cerebrales desde enero de 2010 hasta enero de 2020.Resultados. Ciento ochenta y tres pacientes cumplieron los criterios de inclusión. Se identificaron 131 pacientes con malformaciones arteriovenosas con nido (MAV) y 52 con fístulas directas (sin nido), entre los que se hallaron 19 malformaciones aneurismáticas de vena de Galeno, 23 fístulas piales y 10 fístulas durales. La edad promedio fue de 105 meses para las MAV, 1,7 meses para las malformaciones aneurismáticas de vena de Galeno, 60,5 meses para fístulas piales y 41 meses para fístulas durales.Conclusión. Según su angioarquitectura, las malformaciones vasculares cerebrales de alto flujo tuvieron nido (MAV) o fueron fístulas directas (malformaciones aneurismáticas de vena de Galeno, fístulas piales y fístulas durales). Las MAV se manifestaron a partir de la primera infancia, sobre todo, por hemorragia intracraneana. Las fístulas directas se expresaron en la primera etapa de la vida, frecuentemente, con insuficiencia cardíaca.

Introduction. High-flow vascular malformations of the brain are uncommon in pediatrics. The objective of this study is to establish the differences among these pathologies and group them by age at onset, clinical manifestations, and angioarchitecture.Population and method. This was a retrospective and observational study. The medical records, imaging studies, and procedure protocols of patients seen at Hospital J. P. Garrahan diagnosed with vascular malformations of the brain between January 2010 and January 2020 were analyzed.Results. A total of 183 patients met the inclusion criteria. It was possible to identify 131 patients with arteriovenous malformations with a nidus (AVMs) and 52 with direct fistulas (without a nidus), including 19 vein of Galen aneurysmal malformations, 23 pial fistulas, and 10 dural fistulas. The average age of patients was 105 months for AVMs, 1.7 months for vein of Galen aneurysmal malformations, 60.5 months for pial fistulas, and 41 months for dural fistulas.Conclusion. Based on their angioarchitecture, high-flow vascular malformations of the brain presented a nidus (AVMs) or direct fistulas (vein of Galen aneurysmal malformations, pial fistulas, and dural fistulas). AVMs were observed in early childhood, especially due to intracranial hemorrhage. Direct fistulas occurred in the first stage of life, commonly with heart failure.

Título: Canulación temprana de fístulas arteriovenosas nativas en hemodiálisis. Serie de casos y revisión de la literatura / Early cannulation of native arteriovenous fistulas in hemodialysis. Case reports and literature review
Fonte: Rev. colomb. nefrol. (En línea);7(1):135-142, ene.-jun. 2020. tab, graf.
Idioma: es.
Resumo: Resumen La fístula arteriovenosa nativa (FAVn) constituye el acceso ideal en los pacientes de hemodiálisis, sin embargo, necesita un periodo de maduración desde su construcción quirúrgica; en este periodo, que suele tardar más de 8 semanas, se expone a los pacientes a un tiempo mayor con catéteres. El presente artículo describe cuatro casos de canulación temprana (<3 semanas) que se llevaron a cabo con base en la experticia del personal de enfermería y algunos criterios ecográficos.

Abstract The native arteriovenous fistula (nAVF) is the ideal access in patients in hemodialysis, however, traditionally requires a period of maturation from its surgical construction that usually takes more than 8 weeks, exposing patients to a longer time with catheters; In this article, we describe 4 cases of early cannulation (<3 weeks) based on nursing staff expertise and ultrasound criteria.

Título: Clinical factors that influence the occurrence of symptomatic pseudoaneurysms and arteriovenous fistulas after partial nephrectomy: multi-institutional study of renal function outcomes after one year of selective arterial embolization
Fonte: Int. braz. j. urol;47(1):149-158, Jan.-Feb. 2021. tab, graf.
Idioma: en.
Resumo: ABSTRACT Purpose: Renal artery pseudoaneurysms (RAPs) and arteriovenous fistulas (AVFs) are rare but potentially life-threatening complications after partial nephrectomy (PN). Selective arterial embolization (SAE) is an effective method for controlling RAPs/AVFs. We assessed the clinical factors affecting the occurrence of RAPs/AVFs after PN and the effects of SAE on postsurgical renal function. Materials and Methods: Four hundred ninety-three patients who underwent PN were retrospectively reviewed. They were placed in either the SAE or the non-SAE group. The effects of clinical factors, including R.E.N.A.L. scores, on the occurrence of RAPs/AVFs were analyzed. The influence of SAE on the estimated glomerular filtration rate (eGFR) during the first postoperative year was evaluated. Results: Thirty-three (6.7%) patients experienced RAPs/AVFs within 8 days of the median interval between PN and SAE. The SAE group had significantly higher R.E.N.A.L. scores, higher N component scores, and higher L component scores (all, p <0.05). In the multivariate analysis, higher N component scores were associated with the occurrence of RAPs/AVFs (Odds ratio: 1.96, p=0.039). In the SAE group, the mean 3-day postembolization eGFR was significantly lower than the mean 3-day postoperative eGFR (p <0.01). This difference in the eGFRs was still present 1 year later. Conclusions: Renal tumors located near the renal sinus and collecting system were associated with a higher risk for RAPs/AVFs after PN. Although SAE was an effective method for controlling symptomatic RAPs/AVFs after PN, a procedure-related impairment of renal function after SAE could occur and still be present at the end of the first postoperative year.

Idioma: es.
Resumo: Resumen El acceso vascular en hemodiálisis constituye uno de los pilares de éxito del programa. Por tanto, los esfuerzos se deben encaminar a lograr en primera instancia el mayor número de accesos vasculares tipo fístulas Arteriovenosas, y en segundo lugar a disminuir las complicaciones relacionadas con la canulación del acceso para preservar funcionalmente el mismo. Se han descrito varias estrategias para mejorar este último aspecto; en el presente artículo se describe el uso del ultrasonido para mejorar la probabilidad de canulación exitosa en casos considerados como difíciles por parte del equipo de enfermería.

Abstract Vascular access in hemodialysis constitutes one of the pillars of the success of a program. Efforts should therefore be aimed at achieving, in the first instance, the greatest number of arteriovenous fistula vascular accesses, and secondly at decreasing the complications related to the cannulation of access to preserve the functionally thereof in the long term. Several strategies have been described to improve this last aspect; we describe case reports of the use of ultrasound to improve the probability of successful cannulation in situations considered difficult by the nursing team.

Título: Coronary arteriovenous fistulas in adult patients: surgical management and outcomes
Fonte: Rev. bras. cir. cardiovasc = Braz. j. cardiovasc. surg. (impr.);32(1):15-21, Jan.-Feb. 2017. tab, graf.
Idioma: en.
Resumo: Abstract Objective: The aim of this study was to describe the demographic, clinical and anatomic characteristics of coronary arteriovenous fistulas in adult patients who underwent open cardiac surgery and to review surgical management and outcomes. Methods: Twenty-one adult patients (12 female, 9 male; mean age: 56.1±7.9 years) who underwent surgical treatment for coronary arteriovenous fistulas were retrospectively included in this study. Coronary angiography, chest X-ray, electrocardiography and transthoracic echocardiography were preoperatively performed in all patients. Demographic and clinical data were also collected. Postoperative courses of all patients were monitored and postoperative complications were noted. Results: A total of 25 coronary arteriovenous fistulas were detected in 21 patients; the fistulas originated mainly from left anterior descending artery (n=9, 42.8%). Four (19.4%) patients had bilateral fistulas originating from both left anterior descending and right coronary artery. The main drainage site of coronary arteriovenous fistulas was the pulmonary artery (n=18, 85.7%). Twelve (57.1%) patients had isolated coronary arteriovenous fistulas and 4 (19.4%), concomitant coronary artery disease. Twenty (95.3%) of all patients were symptomatic. Seventeen patients were operated on with and 4 without cardiopulmonary bypass. There was no mortality. Three patients had postoperative atrial fibrillation. One patient had pericardial effusion causing cardiac tamponade who underwent reoperation. Conclusion: The decision of surgical management should be made on the size and the anatomical location of coronary arteriovenous fistulas and concomitant cardiac comorbidities. Surgical closure with ligation of coronary arteriovenous fistulas can be performed easily with on-pump or off-pump coronary artery bypass grafting, even in asymptomatic patients to prevent fistula related complications with very low risk of mortality and morbidity.

Resumo: Abstract Arteriovenous fistula due to coronary angiography intervention is rarely seen. Arteriovenous fistulas may be asymptomatic according to the size of the shunt, as well as to the heart failure. In this case report, we aimed to share gradual transition from endovascular methods to surgery and why surgical treatment is required for a patient who developed arteriovenous fistula after coronary angiography.

Título: Traumatic arteriovenous fistula associated to pseudoaneurysm of the superficial temporal artery in a child: case report and literature review / Fístula arteriovenosa traumática associada a pseudoaneurisma da artéria temporal superficial em uma criança: relato de caso e revisão da literatura

Idioma: en.
Resumo: As fístulas arteriovenosas (FAVs) e os pseudoaneurismas traumáticos extracranianos são malformações incomuns e, em sua maioria, estão associadas a traumatismo craniano fechado com lesão contusa de forte intensidade. O diagnóstico em geral é clínico, porém o exame de escolha para o diagnóstico definitivo é a angiografia. Nos casos em que a lesão é pequena, é possível abordá-la com embolização via endovascular com sucesso. A excisão cirúrgica, no entanto, ainda é o método de escolha para o tratamento. É relatado um caso de um paciente do sexo masculino, com 9 anos de idade, diagnosticado com FAV, acometendo o ramo frontal da artéria temporal superficial, secundária a trauma craniano contundente ocorrido três anos antes do diagnóstico.

The arteriovenous fistulae (AVFs) and the extracranial traumatic pseudoaneurysms are uncommon malformations and in the majority of the cases are associated to closed head trauma with high intensity blunt lesion. The diagnosis is generally clinical, though the exam of choice for definitive diagnosis is an angiography. In minor lesion cases it's possible to successfully approach it with endovas-cular embolization. The surgical excision though, is the method of choice for the treatment. Here is reported a case of a 9-year-old male patient, diagnosed with AVF involving the frontal branch of the superficial temporal artery, secondary to blunt head trauma occurred three years before diagnosis.

Título: Foix-Alajouanine syndrome mimicking a spinal cord tumor / Síndrome de Foix-Alajouanine simulando um tumor intramedular espinal
Fonte: Rev. Assoc. Med. Bras. (1992);63(7):564-565, July 2017. graf.
Idioma: en.
Resumo: Summary Subacute necrotizing myelopathy (SNM) or Foix-Alajouanine syndrome is a rare disease characterized by progressive neurological dysfunction caused by a spinal dural arteriovenous fistula (AVF). Radiological diagnosis is usually suspected when there is intramedullary nonspecific enhancement and perimedullary flow voids. Ring-enhancement is rarely reported in the scope of AVF, which poses a diagnostic challenge and raises the suspicion of a spinal cord tumor. In such situations, biopsy can be required and delay proper diagnosis. We report the case of a patient with SNM, who underwent biopsy on the assumption of it being a spinal cord tumor.

Resumo Mielopatia necrotizante subaguda (MNS) ou síndrome de Foix-Alajouanine é uma doença rara que se caracteriza por disfunção neurológica progressiva causada por uma fístula arteriovenosa espinal dural. O diagnóstico radiológico é comumente suspeitado quando aparece captação não específica de contraste e de artefatos de fluxo (flow voids) perimedulares. Raramente, a captação de contraste exibe o aspecto em anel, constituindo um grande desafio diagnóstico. Nesses casos, o principal diagnóstico diferencial é um tumor intramedular, e os pacientes são encaminhados para biópsia da lesão, atrasando o diagnóstico definitivo. Relatamos o caso de uma paciente com MNS, a qual foi submetida à biópsia da lesão em virtude de suspeita de tumor intramedular.
