ABSTRACT

Introducción: A pesar del gran avance técnico que representan las fístulas arterio-venosas internas para la hemodiálisis, estas no están exentas de complicaciones que comprometen su durabilidad. Entre ellas se encuentran los aneurismas venosos yuxta-anastomóticos. Objetivo: Presentar el tratamiento quirúrgico utilizado para reparar los aneurismas venosos yuxta-anastomóticos. Presentación del caso: Paciente de 54 años, de género femenino y color de piel negra. Presentó antecedentes de padecer insuficiencia renal crónica de 12 años de evolución, con transplante renal fallido, la cual tuvo un aneurisma venoso yuxta-anastomótico, localizado en una fístula arterio-venosa húmero-cefálica en miembro superior izquierdo, que fue confirmado por eco-doppler. Se emplearon como tratamiento quirúrgico la aneurismectomía y el injerto por sustitución con prótesis vascular expandible de poli-tetrafluoretileno. Finalmente, se preservó la fístula arterio-venosa, así como su permeabilidad. Conclusiones: La evolución fue satisfactoria en cuanto a su durabilidad y utilización como vía de acceso para la hemodiálisis(AU)


Introduction: Despite the great technical advance represented by internal arterio-venous fistulas for hemodialysis, these are not exempt from complications that compromise their durability. Among them are juxtaanastomotic venous aneurysms. Objective: Present the surgical treatment used to repair juxtaanastomotic venous aneurysms. Case presentation: 54-year-old patient, female and black skin color. She presented a history of chronic renal failure of 12 years of evolution, with failed kidney transplant, which had a juxtaanastomotic venous aneurysm, located in a humerus-cephalic arterio-venous fistula in the left upper limb, which was confirmed by Doppler echo. Aneurysmectomy and replacement grafting with expandable polytetrafluorethylene vascular prostheses were used as surgical treatment. Finally, the arterio-venous fistula was preserved, as well as its permeability. Conclusions: The evolution was satisfactory in terms of durability and use as an access route for hemodialysis(AU)

ABSTRACT

Abstract Co-occurrence of acute limb ischemia (ALI) and arteriovenous fistula (AVF) as a manifestation of inadvertent arterial injury during percutaneous femoral vein dialysis catheter insertion is a rare and dangerous, but preventable complication. Iatrogenic femoral AVF commonly presents late, with leg swelling or high output cardiac failure. However, the co-occurrence of a femoral AVF with both progressive leg swelling, and acute thromboembolism has not been previously reported. We report the case of an iatrogenic femoral AVF with superficial femoral artery (SFA) thrombosis and distal embolism in a 53-year-old female who underwent percutaneous femoral access for temporary hemodialysis. Both the SFA and AVF were managed with open surgical repair.


Resumo A coocorrência de isquemia aguda de membro (IAM) e fístula arteriovenosa (FAV) como uma manifestação de lesão arterial inadvertida durante a inserção de cateter para hemodiálise por via femoral percutânea é uma complicação rara e perigosa, porém evitável. A FAV femoral iatrogênica geralmente tem apresentação tardia, com edema dos membros inferiores ou insuficiência cardíaca de alto débito. No entanto, a coocorrência de FAV femoral com edema progressivo dos membros inferiores e tromboembolismo agudo não foi previamente relatada. Relatamos o caso de uma FAV femoral iatrogênica com trombose da artéria femoral superficial (AFS) e embolia distal em uma paciente do sexo feminino, 53 anos, submetida à acesso femoral percutâneo para hemodiálise temporária. Tanto a AFS quanto a FAV foram manejadas com reparo cirúrgico aberto.

ABSTRACT

Resumo As fístulas arteriovenosas (FAVs) traumáticas envolvendo os vasos axilares e subclávios são incomuns e correspondem de 5 a 10% de todos os traumas arteriais. A anatomia complexa dessa região torna desafiador o tratamento desse segmento. Neste desafio terapêutico, descrevemos o caso de um homem de 73 anos, encaminhado por edema progressivo e úlcera no membro superior direito, com história pregressa de ferimento por arma de fogo na região infraclavicular direita há cerca de 50 anos. Foi realizada angiotomografia e identificou-se FAV axilo-axilar associada à tortuosidade e dilatação aneurismática de artéria subclávia a jusante. O paciente foi submetido à intervenção endovascular com endoprótese cônica (monoilíaca) 26 × 14 × 90 mm Braile® na artéria subclávia aneurismática, posterior à saída da artéria vertebral direita, e endoprótese monoilíaca 16 × 16 × 95 mm Excluder® com sobreposição na primeira prótese, apresentando resultado satisfatório. Portanto, descreve-se a possibilidade de utilização de endoprótese aórtica em situação incomum e de exceção, com sucesso.


Abstract Traumatic arteriovenous fistulas (AVFs) involving the axillary and subclavian vessels are uncommon and account for 5 to 10% of all arterial traumas. The complex anatomy of this region makes treatment of this segment challenging. In this therapeutic challenge, we describe the case of a 73-year-old man, referred for progressive edema and ulceration involving the right upper limb and with a history of gunshot wound to the right infraclavicular region about 50 years previously. Angiotomography was performed and an axillary-axillary AVF was found, associated with tortuosity and aneurysmatic dilation of the subclavian artery downstream. He underwent endovascular intervention and a conical (monoiliac) 26 × 14 × 90 mm Braile® endoprosthesis was used in the aneurysmatic subclavian artery, posterior to the exit of the right vertebral artery and a 16 × 16 × 95mm Excluder® monoiliac endoprosthesis was placed overlapping the first prosthesis, showing a satisfactory result. Therefore, the possibility of successfully using aortic endoprostheses in an unusual and exceptional situation is described.

ABSTRACT

Introducción: Las complicaciones cardiovasculares constituyen la primera causa de morbilidad y mortalidad en el receptor de trasplante renal. Objetivo: Caracterizar la repercusión de la fístula arteriovenosa sobre variables hemodinámicas del corazón derecho en trasplante renal. Métodos: Estudio prospectivo, longitudinal. Se incluyeron 52 pacientes, evaluados clínica y ecocardiográficamente. Se compararon cinco variables hemodinámicas en el corazón derecho, previos y seis meses posteriores al cierre de la fístula arteriovenosa. Resultados: La edad promedio 46,02 años, 29 masculinos (55,8 por ciento). El diámetro de la aurícula derecha en las fístulas cerradas en la muñeca izquierda 8805; 6 años disminuyó (p=0,044), al igual que en el ventrículo derecho <6 años a nivel del pliegue del codo izquierdo (p=0,004). La presión sistólica de la arteria pulmonar descendió tras el cierre en el codo izquierdo lt;6 años (p=0,002), en las 8805;6 (p=0,05) y en el derecho (p=0,006). La presión media de la arteria pulmonar se redujo en las cerradas en pliegue del codo izquierdo <6 años (p=0,001) y 8805;6 años (p=0,017) al igual que en el derecho (p=0,009). La fracción de eyección del ventrículo derecho se incrementó al cierre en muñeca izquierda ;6 años (p=0,046) y en el codo derecho 8805;6 años (p=0,027). Conclusiones: La permanencia de la fístula arteriovenosa en el receptor de trasplante renal contribuye a la perpetuación y progresión de la disfunción cardiovascular preexistente(AU)


Introduction: Cardiovascular complications are the leading cause of morbidity and mortality in kidney transplant recipients. Objective: To describe the consequence of arteriovenous fistula on hemodynamic variables of the right heart in kidney transplantation. Methods: We conducted a prospective, longitudinal study. Fifty two patients were included, and they were clinically and echocardiographically assessed. Five hemodynamic variables were compared in the right heart, prior to the closure of the arteriovenous fistula and six months after. Results: The average age was 46.02 years, 29 were male (55.8 percent). The diameter decreased in the right atrium in closed fistulas in the left wrist #8805; 6 years (p = 0.044). The same occurred in the right ventricle <6 years at the level of the left elbow crease (p = 0.004). The systolic pressure of the pulmonary artery decreased after closure in the left elbow <6 years (p = 0.002), in ≥6 (p = 0.05) and in the right (p = 0.006). The mean pressure of the pulmonary artery was reduced in those closed in the crease of the left elbow <6 years (p = 0.001) and ≥6 years (p = 0.017) as well as in the right (p = 0.009). The right ventricular ejection fraction increased at closure in the left wrist <6 years (p = 0.046) and in the right elbow ≥6 years (p = 0.027). Conclusions: The permanence of arteriovenous fistula in the kidney transplant recipient contributes to the perpetuation and progression of the pre-existing cardiovascular dysfunction(AU)

ABSTRACT

ABSTRACT Introduction: The increasing prevalence of chronic kidney disease has increased the demand for arteriovenous fistula (AVF) care. The objective of this study was to assess the relationship between some risk factors for AVF failure (advanced age, female sex, diabetes, obesity, central venous catheter, previous fistula, and hospitalization) and having a Doppler ultrasound performed preoperatively. Methods: A prospective study was performed with 228 dialysis patients from Imperatriz, Maranhão. Half of the sample was randomly selected to receive preoperative Doppler ultrasound and the other half did not, from the period of October 2016 to September 2018. Results: There were 53 total failures corresponding to 23.2% of our sample, which is almost double that of the patients in the clinical group. Considering the failures and risk factors associated with the overall sample, there was a statistically significant association between a central venous catheter on the same side of the AVF with P = 0.04 (Odds Ratio 1.24) and obesity with P = 0.05 (Odds Ratio 1.36), which was not repeated in the Doppler ultrasound group individually. There was no statistically significant difference between the Doppler group and clinical group with respect to the amount of days of previous AVF hospitalization and failure. Conclusions: We concluded that the reduction of failures with an introduction of the Doppler was statistically significant in the overall sample, but establishing a relationship between specific risk factors and failure was only possible with two of the risk factors in the study - obesity and central venous catheter on the same side of the AVF.


RESUMO Introdução: A crescente prevalência de doença renal crônica aumentou a demanda por confecção de fístula arteriovenosa (FAV). O objetivo do presente estudo foi avaliar a relação entre alguns fatores de risco para falha da FAV (idade avançada, sexo feminino, diabetes, obesidade, cateter venoso central, fístula prévia e hospitalização) e a realização de ultrassonografia Doppler no pré-operatório. Métodos: Estudo prospectivo com 228 pacientes em diálise em Imperatriz, MA. Metade da amostra foi randomizada para receber ultrassonografia Doppler no pré-operatório. A outra metade dos pacientes não foi submetido a exame ultrassonográfico. O estudo incluiu pacientes atendidos no período de outubro de 2016 a setembro de 2018. Resultados: Houve 53 falhas (23,2%) em nossa amostra, quase o dobro do número dos pacientes no grupo clínico. Considerando as falhas e os fatores de risco associados à amostra geral, houve associação estatisticamente significativa entre catéter venoso central do mesmo lado da FAV (P = 0,04; Razão de Chances: 1,24) e obesidade (P = 0,05; Razão de Chances: 1,36), o que não foi reproduzido no grupo de ultrassonografia Doppler individualmente. Não houve diferença estatisticamente significativa entre o grupo Doppler e o grupo clínico em relação à quantidade de dias de internação e falha da FAV. Conclusões: A redução de falhas com a introdução do Doppler foi estatisticamente significativa na amostra geral, mas só foi possível estabelecer uma relação entre fatores de risco específicos e falha em dois dos fatores estudados, obesidade e catéter venoso central no mesmo lado da FAV.

ABSTRACT

RESUMEN El embolismo por cristales de colesterol (ECC) es una complicación de la enfermedad arterioesclerótica en la que el desprendimiento de fragmentos de placa de ateroma, principalmente de grandes arterias, provoca oclusión de pequeños vasos. Esta entidad, también llamada ateroembolia o síndrome de los dedos del pie azules, es más frecuente en pacientes de edad avanzada y después de procedimientos invasivos intravasculares. Se manifiesta con cianosis, livedo reticularis, necrosis y úlceras asociado a manifestaciones renales y gastrointestinales. Se presenta un paciente trasplantado renal y portador de fístula arteriovenosa trombosada izquierda con ateroembolia localizada en mano homolateral.


ABSTRACT The cholesterol crystal embolism (ECC) is a complication of arteriosclerotic disease in which the detachment of fragments of atheromatous plaque mainly from large arteries, causes occlusion of small vessels. This entity, also called atheroembolism or blue toe syndrome, is more common in elderly patients and after intravascular invasive procedures. It manifests with cyanosis, livedo reticularis, necrosis and ulcers associated with renal and gastrointestinal manifestations. We present a renal transplant patient with a left thrombosed arteriovenous fistula with atheroembolism located in homolateral hand.

ABSTRACT

Resumo A síndrome da fístula artério-portal (FAP) é uma rara e reversível causa de hipertensão portal pré-sinusoidal, ocasionada pela comunicação de uma artéria visceral com o sistema venoso portal. A maioria dos pacientes é assintomática, mas quando desenvolvem sintomas, estes são mais relacionados com sangramento gastrointestinal, ascite, insuficiência cardíaca congestiva e diarreia. Este desafio terapêutico apresenta um caso de FAP decorrente de ferimento antigo por arma branca e subsequente evolução clínica desfavorável, com grave desnutrição e frequentes hemorragias digestivas. O caso foi solucionado através de oclusão da FAP por meio de tratamento endovascular.


Abstract The arterioportal fistula (APF) syndrome is a rare and reversible cause of pre-sinusoidal portal hypertension, caused by communication between a visceral artery and the portal venous system. Most patients are asymptomatic, but when they do develop symptoms, these are mainly related to gastrointestinal bleeding, ascites, congestive heart failure, and diarrhea. This therapeutic challenge presents a case of APF caused by a 20-year-old stabbing injury with unfavorable late clinical evolution, including significant malnutrition and severe digestive hemorrhages. The patient was treated using an endovascular procedure to occlude of the fistula.

ABSTRACT

Objetivo: Identificar os fatores de risco/condicionantes para a falência da fístula arteriovenosa e analisar os cuidados necessários para manutenção da fístula arteriovenosa. Métodos: Estudo piloto realizado com 10 participantes com histórico de falência de fístula arteriovenosa, com dados coletados por meio de formulário e analisados por estatística descritiva, aceito pelo Comitê de Ética em Pesquisa do Hospital Universitário Pedro Ernesto, com número do CAAE nº 64150117.2.0000.5259. Resultados: A idade média foi de 57,3 anos. A hipertensão arterial foi a doença prévia mais comum encontrada entre os participantes. A hipotensão e as punções repetidas foram os fatores de risco/condicionantes com maior ocorrência. Conclusão: a maioria dos participantes possuíam baixa escolaridade e informaram ter tido alguma complicação na FAV. A hipotensão como fator condicionante para falência das FAV, permaneceu de forma frequente entre os participantes. Observou-se que grande parte já realizava tratamento dialítico prévio


Objective: The study's purpose has been to identify the risk/conditioning factors for Arteriovenous Fistula Failure (AVF), and also to analyze the care required for handling the arteriovenous fistula. Methods: It is a pilot study that was carried out with 10 participants showing a history of AVF. The data were collected through a form and analyzed by descriptive statistics. This research was accepted by the Research Ethics Committee from the Pedro Ernesto University Hospital, under the Certificado de Apresentação para Apreciação Ética (CAAE) [Certificate of Presentation for Ethical Appreciation] No. 64150117.2.0000.5259. Results: The average age was 57.3 years old. Arterial hypertension was the most common prior disease among the participants. Hypotension and repeated punctures were the most frequent risk/conditioning factors. Conclusion: A relevant percentage of the participants had little education and reported having had some complication in the AVF. Hypotension, as a conditioning factor for AVF failure, remained frequent among the participants. It was observed that a large part of the participants have undergone dialysis treatment previously

ABSTRACT

Abstract Introduction: Vascular access (VA) in hemodialysis (HD) is essential to end-stage renal disease (ESRD) patients survival. Unfortunately, after some years in HD program, a significant number of patients may develop VA failure for many reasons. In this situation, arterial venous fistula (AVF) confection or catheters placement in traditional vascular sites (jugular, femoral or subclavian) are not feasible. In this scenario, translumbar tunneled dialysis catheter (TLDC) may be a salvage option. Objectives: To describe placement technic, complications, and patency of 12 TLDC. Methods: A retrospective study was performed to analyze 12 TLDC placement in an angiography suite using fluoroscopic guidance at the University Hospital of the Rio Grande do Norte Federal University from January 2016 to October 2017. The data collected of the total procedures performed consisted of demographic characteristics, success rates, observed complications, patient survival, and catheter patency. Results: All 12 TLDC were placed with success; there were only 2 significant periprocedure complications (major bleeding and extubation failure); 41.6% of patients presented a catheter-related first infection after 98 ± 72.1 (6-201) days, but catheter withdrawal was not necessary, mean total access patency was 315.5 (range 65 - 631) catheter-days, and catheter patency at 3, 6 and 12 months was 91 %, 75%, and 45%. Conclusion: TLDC is an option for patients with VA failure, improving survival and acting as a bridge for renal transplantation.


Resumo Introdução: O acesso vascular (AV) para hemodiálise (HD) é crucial para os pacientes portadores de doença renal crônica (DRC) estágio V. Infelizmente, com o passar dos anos, um percentual não desprezível desses enfermos evolui para falência de AV por diversos motivos, o que impossibilita a confecção de novas fístulas arteriovenosas (FAV) ou o implante de cateteres venosos centrais nos sítios de punções tradicionais. Nesse cenário, o implante de cateteres translombares para hemodiálise (CTLHD) em veia cava inferior ganha destaque como medida salvadora. Objetivos: Relatar uma série de 12 casos de implante de CTLHD, sua técnica de implante, patência e complicações. Métodos: Estudo retrospectivo que analisou 12 implantes de CTLHD por radiologista intervencionista no setor de hemodinâmica do Hospital Universitário da Universidade Federal do Rio Grande do Norte (UFRN), no período de janeiro/2016 a outubro/2017. Os dados coletados consistiram em: características demográficas da população estudada, taxa de sucesso, complicações observadas, sobrevida dos pacientes, patência do cateter e desfechos clínicos. Resultados: Todos os 12 CTLHD foram implantados e utilizados com sucesso; ocorreram apenas 2 complicações associadas ao procedimento (sangramento e falha na extubação); 41,6% dos pacientes apresentaram infecção relacionada ao cateter após 98 ± 72,1 dias (6-201 dias), mas não houve necessidade de remoção; e a patência foi de 315,5 cateteres-dia (65-631 dias). Conclusão: O CTLHD é uma opção para pacientes com falência de acesso vascular, prolongando a sobrevida dos pacientes e atuando como ponte para o transplante renal.

ABSTRACT

En el tratamiento de enfermos renales en fase terminal, se realizan accesos vasculares para hemodiálisis. Son hechos habitualmente, en las venas de los miembros superiores, especialmente la técnica de Brecia y Cimino (fístula arteriovenosa latero lateral de la cefálica y la radial en la muñeca). La mayor complicación, directamente relacionada con un flujo excesivo por la fístula arteriovenosa, es la insuficiencia cardíaca congestiva. Se presenta el caso de un paciente con una fístula arteriovenosa (iatrogénica) que causó una insuficiencia cardiaca congestiva. El paciente, hipertenso conocido, tuvo un acceso venoso de más de 10 años de evolución (por un aparente diagnóstico y para una futura hemodiálisis que nunca fue efectuada). Acudió a consulta con disnea y edemas periféricos. Al examen físico se encontró la tensión arterial en 160 y 100 mm Hg, signos clínicos de cardiomegalia, edemas periféricos, ingurgitación yugular y hepatomegalia. Se palpó un thrill sistodiastólico en la muñeca izquierda, donde presentaba una cicatriz. Pudo observarse marcada dilatación y endurecimiento de todas las venas superficiales del plexo braquial de ese lado, (arterialización del árbol venoso del miembro superior izquierdo hasta las venas superficiales del hemitórax). Se diagnosticó una insuficiencia cardiaca de gasto alto, mejoró con el tratamiento habitual, pero continuó con la malformación venosa adquirida. Fue un caso muy llamativo, que muestra una complicación poco frecuente de los accesos venosos para hemodiálisis y también una causa mencionada, pero escasamente vista, de insuficiencia cardiaca de gasto elevado(AU)


In the treatment of renal patients in terminal phase. Vascular accesses are used for hemodialysis. They are usually performed in the veins of the upper limbs, especially using Brecia and Cimino technique (lateral arteriovenous fistula of the cephalic and radial at the wrist). The major complication, directly related to an excessive flow of arteriovenous fistula, is congestive heart failure. We present the case of a patient with an arteriovenous (iatrogenic) fistula that caused a congestive heart failure. He is hypertensive and had venous access for over 10 years of evolution (for an apparent diagnosis and for future hemodialysis, which was never performed). He went to the clinic with dyspnea and peripheral edema. Physical examination revealed blood pressure of 160 and 100 mm Hg, clinical signs of cardiomegaly, peripheral edema, jugular engorgement and hepatomegaly. We found a systodiastolic thrill on his left wrist, where there is a scar. A marked dilation and hardening of all the superficial veins of the brachial plexus on that side was observed, that is arterialization of the venous tree of the left upper limb to the superficial veins of hemitorax. The diagnosis was high output heart failure. He improved with the usual treatment, but the acquired venous malformation continued in an iatrogenic manner. It was a very striking case because of the infrequent complication of venous accesses for hemodialysis and because for rarely seen elevated heart failure(AU)

ABSTRACT

ABSTRACT Objective: To understand the experience of people with chronic kidney disease using arteriovenous fistula. Method: Qualitative and exploratory study based on Social Phenomenology, conducted on 30 adults undergoing hemodialysis by using the fistula, interviewed in 2017. The interviews were analyzed according to the empirical-comprehensive model proposed by Amedeo Giorgi. Results: We found the categories "The changed body aesthetics"; "The perception of the other about my body"; and "The fistula as an inseparable condition for life maintenance." Final considerations: The experience of people using fistula showed that this venous access leaves marks that change the body aesthetics, making the body imperfect. Such changes cause low self-esteem and attract the look of the other, causing embarrassment in those who have the body changed. Thus, they react by camouflaging the fistula, without which there is no life. This perception arises from the fear that works as a catalyst for self-care.


RESUMEN Objetivo: Comprender la vivencia de personas con enfermedad renal crónica en uso de fístula arteriovenosa. Método: Estudio cualitativo y exploratorio fundamentado en la fenomenología social, realizado con treinta adultos en tratamiento hemodialítico por medio de fístula, entrevistados en 2017. Los testimonios fueron analizados según el modelo empírico-comprensivo propuesto por Amedeo Giorgi. Resultados: Se desvelaron las categorías "La estética corporal alterada"; "La mirada del otro sobre mi cuerpo"; y "La fístula como condición indisociable al mantenimiento de la vida". Consideraciones finales: La vivencia de personas en uso de fístula reveló que ese acceso venoso deja marcas que alteran la estética corporal, haciendo el cuerpo imperfecto. Esos cambios provocan baja autoestima y atraen la mirada del otro, causando constreñimiento en el que tiene el cuerpo marcado. Este, a su vez, reacciona camuflando la fístula, sin la cual no hay vida. De esa percepción surge el miedo, que actúa como catalizador para el autocuidado.


RESUMO Objetivo: Compreender a vivência de pessoas com doença renal crônica em uso de fístula arteriovenosa. Método: Estudo qualitativo e exploratório, fundamentado na fenomenologia social, realizado com 30 adultos em tratamento hemodialítico por meio de fístula, entrevistados em 2017. Os depoimentos foram analisados segundo o modelo empírico-compreensivo proposto por Amedeo Giorgi. Resultados: Foram desveladas as categorias: A estética corporal alterada; O olhar do outro sobre o meu corpo; e A fístula como condição indissociável à manutenção da vida. Considerações finais: A vivência de pessoas em uso de fístula revelou que esse acesso venoso deixa marcas no corpo que alteram a estética corporal, tornando o corpo imperfeito. Essas alterações provocam baixa autoestima, e atraem o olhar do outro, causando constrangimento naquele que tem o corpo marcado. Esse, por sua vez, reage camuflando a fístula, sem a qual não há vida. Dessa percepção surge o medo, que atua como catalisador para o autocuidado.

Objective: to evaluate the performance of the Buttonhole technique during hemodialysis sessions at a service in Natal/RN- Brazil. Method: This is a descriptive, exploratory and observational study that was performed with 17 users of a hemodialysis health service, with data collected in 2016, using a check-list questionnaire and visual analog scale. Results: The majority of the subjects were men (76.5%). The women presented arterial hypertension and chronic renal insufficiency as a disease based on the variables gender, age, alcohol use and other drugs, for both sexes. On the implementation of Bottonhole, the greatest frequency of arteriovenous access, between the sexes, was the radiocephalic. The direct and indirect complications of the button were more frequent in males, with chills, tremors, button infection and access bleeding. Conclusion: The Buttonhole technique was well accepted and performed in the service, contributing to the reduction of pain intensity and the best aesthetic of the user.

ABSTRACT

Introduction: Chronic kidney disease (CKD) is characterized by slow, progressive, and irreversible loss of kidney function. CKD has become a serious public health issue because of its increasing morbidity and mortality rates. The present study aimed to investigate factors associated with hematomas caused by arteriovenous fistula (AVF) at a Renal Replacement Therapy Unit in the state of Rio Grande do Sul, southern Brazil. Methods: In this cross-sectional study, 72 patients with CKD aged 18 years or over, presenting with AVF, and undergoing three hemodialysis sessions per week were evaluated from June 2014 to March 2015. Prevalence ratios (PRs) with 95% confidence intervals (95% CIs) were estimated for identification of risk factors associated with AVF. P-values < 0.05 were considered significant. Results: Sex, age, self-reported skin color, educational level, hypertension, diabetes, nephrotic syndrome, congestive heart failure, and hepatitis C were not associated with hematoma formation (i.e., all estimated PRs had p-values > 0.05). The single factor associated with hematomas was AVF time shorter than 60 days (PR = 2.04; 95% CI: 1.28-3.27; p < 0.01). Conclusion: AVF maturation time was associated with higher prevalence of hematomas at the cannulation site. Therefore, AVF time should be given special attention in patients undergoing renal therapy at dialysis centers. (AU)

ABSTRACT

We investigated the risk factors for pulmonary hypertension (PH) in patients receiving maintenance peritoneal dialysis (MPD). A group of 180 end-stage renal disease patients (124 men and 56 women; mean age: 56.43±8.36) were enrolled in our study, which was conducted between January 2009 and June 2014. All of the patients received MPD treatment in the Dialysis Center of the Second Affiliated Hospital of Soochow University. Clinical data, laboratory indices, and echocardiographic data from these patients were collected, and follow-ups were scheduled bi-monthly. The incidence and relevant risk factors of PH were analyzed. The differences in measurement data were compared by t-test and enumeration data were compared with the χ2 test. Among the 180 patients receiving MPD, 60 were diagnosed with PH. The remaining 120 were regarded as the non-PH group. Significant differences were observed in the clinical data, laboratory indices, and echocardiographic data between the PH and non-PH patients (all P<0.05). Furthermore, hypertensive nephropathy patients on MPD showed a significantly higher incidence of PH compared with non-hypertensive nephropathy patients (P<0.05). Logistic regression analysis showed that the proportion of internal arteriovenous fistula, C-reactive protein levels, and ejection fraction were the highest risk factors for PH in patients receiving MPD. Our study shows that there is a high incidence of PH in patients receiving MPD and hypertensive nephropathy patients have an increased susceptibility to PH.

ABSTRACT

El acceso vascular ideal debe proporcionar un flujo adecuado a las necesidades de la diálisis, debe ser de larga duración y tener una baja tasa de complicaciones. La realización de una fístula autóloga se considera de primera elección como acceso vascular para la hemodiálisis. Si bien se conocen las causas de los aneurismas y pseudoaneurismas de las fistulas, estos son muy pocos frecuentes y por ello es importante conocer que aparecen. Mostramos varios casos de aneurismas y pseudoaneurismas de las fístulas, causas y que hacer para evitarlos. Se presentan seis casos de pacientes con fístulas arteriovenosas para hemodiálisis realizada la cirugía en el hospital "Victoria Mahe" de islas Seychelles en dos años, el diagnóstico fue clínico y ultrasonográfico. Se encontró un paciente diabético de edad avanzada con pseudoaneurismas de la arteria de la fístula luego de su ligadura a nivel del codo; uno con múltiples aneurismas venosos en una fístula de más de cinco años de evolución y cuatro pacientes con pseudoaneurismas de la vena por ruptura de las fístulas. Es importante no solo hacer un acceso vascular para diálisis, sino cuidar del mismo para evitar que aparezcan los aneurismas y pseudoaneurismas, para ello: rotar los sitios de punción, evitar la hipotensión severa, educar a los pacientes sobre lo que no deben hacer con el brazo de la fístula y realizar una buena asepsia y antisepsia antes de iniciar la diálisis para evitar la sépsis y con ello otras complicaciones, y preparar al personal de enfermería que realizará el proceder(AU)


The ideal vascular access should provide adequate flow to meet dialysis requirements, should be long lasting and also have a low rate of complications. Autologous fistula is considered the first choice for vascular access in hemodialysis. If the causes of aneurysms and pseudoaneurysms of fistulae are well known, they are very unusual and so, it is important to know why they occur. Several cases of aneurysms and pseudoaneurysms of fistulae, their causes and how to prevent them were shown. Six cases with arteriovenous fistulae for hemodialysis were presented; the surgery was performed in "Victoria Mahe" Hospital in Seychelles islands in two years, the diagnosis was clinical and ultrasonographic. There were one elderly diabetic patient with pseudo-aneurysm in the artery of the fistula after ligation at the elbow, one with multiple venous aneurysms in a fistula of over 5 years of progression and four patients with vein pseudo-aneurysms due to fistula rupture. It is very important not only to make a vascular access for dialysis, but also to take care of it so as to avoid aneurysms and pseudoaneurysms. To this end, it is advisable to rotate the puncture sites, to severe hypotension, to educate patients about what should not be done with the fistula arm, to perform good aseptic- antiseptic actions before starting dialysis to prevent sepsis and other complications and to prepare nurses to conduct the procedure(AU)

ABSTRACT

Introducción: la fístula arteriovenosa es una técnica quirúrgica importante en los pacientes con insuficiencia renal crónica, ya que de este acceso vascular depende el logro en la hemodiálisis. Objetivo: determinar el comportamiento de las fístulas arteriovenosas para hemodiálisis en pacientes con insuficiencia renal crónica. Métodos: se estudiaron 53 pacientes operados de fístulas arteriovenosas en el Hospital "Victoria" de Mahe, Isla Seychelles, entre abril de 2010 y noviembre de 2011. Se recogieron las siguientes variables: edad, sexo, enfermedades asociadas, localización de la fístula, su utilización en la hemodiálisis y sus complicaciones. Resultados: la mayoría de los pacientes tenían entre 41 y 60 años y eran del sexo masculino, todos padecían de hipertensión arterial. Se realizaron 71 fístulas arteriovenosas por anastomosis término lateral: 27 (38,02 por ciento) radio-cefálica, 37 (52,11 por ciento) húmero-cefálica, 6 (8,45 por ciento) húmero-basílica y 1 (1,4 por ciento) fémoro-femoral con prótesis de politetrafluoroetileno. Funcionaron bien 44 fístulas (61,9 por ciento) y 33 (75 por ciento) fueron útiles en la hemodiálisis. Se complicaron 24 (33,8 por ciento) con una mayor frecuencia de trombosis 20 (28,2 por ciento) sobre todo en las radio-cefálicas (14). Se produjo infección con el uso de prótesis de politetrafluoroetileno. Hubo 6 (8,4 por ciento) fallecidos por complicación de la propia enfermedad. Conclusiones: se lograron buenos resultados en la realización de las fístulas para hemodiálisis con la técnica quirúrgica empleada a pesar de las dificultades encontradas para que los pacientes de consulta externa acepten ser operados antes del uso de la hemodiálisis(AU)


Introduction: the arteriovenous fistula is an important surgical technique for treating patients with chronic renal failure since successful hemodialysis depends on this vascular access. Objective: to determine the behavior of the arteriovenous fistula for hemodialysis in patients with chronic renal failure. Methods: study of 53 patients who had been operated on by the arteriovenous fistula technique at "Victoria" hospital of Mahe, Seychelles Islands from April 2010 through November 2011. The study variables were age, sex, related diseases, location of the fistula, its use in the hemodialysis and complications. Results: most of the patients were males aged 41 to 60 years and all suffered from hypertension. Seventy one arteriovenous fistulas were applied through termino lateral anastomosis: 27 (38.02 percent) radiocephalic, 37 (52.11 percent) humerus-cephalic, 6 (8.45 percent) humerus-basilic and 1 (1.4 percent) femorofemoral with polytetrafluoroethylene prosthesis. Of this group, 44 fistulas (61.9 percent) worked well and 33 (75 percent) were useful in hemodialysis. Complications were found in 24 (33.8 %) with higher thrombosis frequency in 20 (28.2 percent) especially in the radiocephalic type (14). Infection occurred as a result of the use of the prosthesis. Six people (8.4 percent) died of disease complications. Conclusions: Good results were achieved in performing arteriovenous fistulae with this surgical procedure in spite of the difficulties in obtaining the outpatients' consent to be operated on before applying hemodialysis(AU)

ABSTRACT

BACKGROUND: Many chronic renal patients lack autologous veins in the upper limbs suitable for construction of arteriovenous fistulas for hemodialysis. Alternative fistula options for these patients should be evaluated and compared.OBJECTIVE: To compare different types of grafts used for brachioaxillary access in hemodialysis patients in terms of their patency and complication rates.METHOD: Forty-nine patients free from arterial system abnormalities and with no venous options for creation of arteriovenous fistulae in the arm and/or forearm underwent brachioaxillary bypass with implantation of autologous saphenous vein, polytetrafluoroethylene (PTFE), or PROPATEN(r) grafts. Patients were assessed by Doppler ultrasonography at 3, 6, and 12 months after surgery. RESULTS: The four first saphenous vein grafts had failed by 3 or 6 months after surgery. The autologous saphenous vein group was discontinued at the beginning of the study because of extreme difficulty in achieving puncture and hematoma formation. Failure rates of PTFE and PROPATEN(r) grafts did not differ after 3 (p = 0.559), 6 (p = 0.920), or 12 months (p = 0.514). A log-rank test applied to cumulative survival of grafts at 1 year (0.69 for PTFE, 0.79 for PROPATEN(r)) detected no significant differences (p = 0.938). There were no differences in complications resulting in graft failure between the two types of prosthetic graft.CONCLUSION: Autologous saphenous vein grafts do not appear to be a good option for brachioaxillary hemodialysis access because of difficulties with achieving puncture. Brachioaxillary fistulae constructed using PTFE or PROPATEN(r) grafts exhibited similar patency and complication rates. Further studies with large samples size are warranted to confirm our findings.


CONTEXTO: Há inúmeros pacientes renais crônicos sem veias autólogas nos membros superiores para confecção de fístulas arteriovenosas para realização de hemodiálise. As opções de fístula nestes pacientes devem ser avaliadas e comparadas.OBJETIVO: Comparar diferentes enxertos para acesso braquioaxilar em pacientes hemodialíticos, em relação a permeabilidade e taxas de complicação. MÉTODO: Um grupo de 49 pacientes, sem alterações no sistema arterial e sem opções venosas para criação de fístula arteriovenosa no braço e/ou antebraço, foi submetido a procedimentos cirúrgicos para implante de diferentes enxertos: veia safena autóloga, enxertos de PTFE e PROPATEN(r).RESULTADOS: Os quatro primeiros implantes de veia safena falharam no terceiro e no sexto mês após a cirurgia. Interrompeu-se o uso de veia safena autóloga no início do estudo pela extrema dificuldade de punção e pela formação de hematoma. Não houve diferenças nas taxas de falha dos enxertos de PTFE e PROPATEN(r) após três (p = 0,559), seis (p = 0,920) e 12 meses (p = 0,514) de seguimento. O teste de Logrank aplicado à sobrevida cumulativa dos enxertos por um ano (0,68 para PTFE; 0,79 para PROPATEN(r)) não relevou diferenças (p = 0,938). Não foram encontradas diferenças entre os enxertos prostéticos em relação ao tipo de complicação que determinou as falhas.CONCLUSÃO: O enxerto de veia safena autóloga parece não ser é uma boa opção para acesso braquioaxilar em hemodialíticos, já que implica em dificuldade na punção. Os enxertos de PTFE e PROPATEN(r) em fistula braquioaxilar resultaram em permeabilidade e taxas de complicações similares. Estudos com amostras maiores são necessários para confirmar nossos achados.
