[Palliative and Supportive Dialysis: Current Practices and Recommendations for Best Clinical Practice].

"Palliative dialysis" is defined as the renal replacement therapy directed to patients living the most critical phases of illness and the end-of-life stage. Offering targeted dialysis prescriptions becomes imperative when health conditions, along with comorbidities, unfavorable prognosis and complications, do not allow standard dialysis to be started or continued. Management should also integrate adequate supportive care measures in both incident and prevalent patients. This document summarizes nephrological recommendations and scientifical evidence regarding the palliative approach to dialysis, and proposes operative tools for a good clinical practice. After planning and sharing the route of care ("shared-decision-making"), which includes multidimensional evaluation of the patient, a pathway of treatment should be started, focusing on combining the therapeutical available options, adequacy and proportionality of care and patients' preferences. We propose a framework of indications that could help the nephrologist in practicing appropriate measures of treatment in patients' frailest conditions, with the aim of reducing the burden of dialysis, improving quality of life, providing a better control of symptoms, decreasing the hospitalization rates in the end-of-life stage and promoting a home-centered form of care. Such a decisional pathway is nowadays increasingly needed in nephrology practice, but not standardized yet.

A call to optimize haemodialysis vascular access care in healthcare disrupted by COVID-19 pandemic.

The COVID-19 pandemic has resulted in major disruption to the delivery of both routine and urgent healthcare needs in many institutions across the globe. Vascular access (VA) for haemodalysis (HD) is considered the patient's lifeline and its maintenance is essential for the continuation of a life saving treatment. Prior to the COVID-19 pandemic, the provision of VA for dialysis was already constrained. Throughout the pandemic, inevitably, many patients with chronic kidney disease (CKD) have not received timely intervention for VA care. This could have a detrimental impact on dialysis patient outcomes in the near future and needs to be addressed urgently. Many societies have issued prioritisation to allow rationing based on clinical risk, mainly according to estimated urgency and need for treatment. The recommendations recently proposed by the European and American Vascular Societies in the COVID-19 pandemic era regarding the triage of various vascular operations into urgent, emergent and elective are debatable. VA creation and interventions maintain the lifeline of complex HD patients, and the indication for surgery and other interventions warrants patient-specific clinical judgement and pathways. Keeping the use of central venous catheters at a minimum, with the goal of creating the right access, in the right patient, at the right time, and for the right reasons, is mandatory. These strategies may require local modifications. Risk assessments may need specific "renal pathways" to be developed rather than applying standard surgical risk stratification. In conclusion, in order to recover from the second wave of COVID-19 and prepare for further phases, the provision of the best dialysis access, including peritoneal dialysis, will require working closely with the multidisciplinary team involved in the assessment, creation, cannulation, surveillance, maintenance, and salvage of definitive access.

Project of the Health Policy Program: Access to Vessels in Renal Replacement Therapy - Fistula First/Catheter Last.

INTRODUCTION: The number of patients with end-stage renal failure (ESRF) that require inclusion in the renal replacement therapy program (RRT) is steadily increasing. This fact caused an increase in vascular operations involving the production of vascular access. According to the current guidelines, the best and safest option for a patient with chronic kidney disease (CKD) is the early creation of arteriovenous fistula (AVF). An efficient vascular access to haemodialysis determines the procedure and directly affects the quality of life of a patient with CKD. AIM: The aim of this paper is to present the author's project of the health policy program "Vascular access in renal replacement therapy - fistula first/catheter last", the essence of which is to assess the practical effectiveness and develop an optimal model of CKD patient care organization qualified for the chronic RRT program. MATERIAL AND METHODS: The target population of the program consists of all patients diagnosed with CKD, qualified for the RRT program. The basic measures of the program's effectiveness include: (1) reduction in the number of re-hospitalizations related to vascular access, (2) reduction in the number of complications associated with haemofiltration surgery, (3) reduction in general mortality among patients undergoing dialysis in a 12-month perspective, (4) increasing knowledge in the field of self-care and self-care of arteriovenous anastomosis, and (5) creating a register of vascular access in Poland. CONCLUSIONS: To sum up, health policy programme "Vascular access in renal replacement therapy - fistula first/catheter last" covering health care services provided in the scope and on the conditions specified in the regulations issued on the basis of article 31d of the Act of 27 August 2004 on health care benefits financed from public funds, is to check whether planned changes in the organization and delivery of services will improve the situation of patients with CKD eligible for chronic RRT and whether it will be effective the point of view of the health care system.

Kidney health for everyone everywhere-from prevention to detection and equitable access to care.

The global burden of chronic kidney disease (CKD) is rapidly increasing with a projection of becoming the 5th most common cause of years of life lost globally by 2040. Aggravatingly, CKD is a major cause of catastrophic health expenditure. The costs of dialysis and transplantation consume up to 3% of the annual healthcare budget in high-income countries. Crucially, however, the onset and progression of CKD are often preventable. In 2020, the World Kidney Day campaign highlights the importance of preventive interventions-be it primary, secondary, or tertiary. This complementing article focuses on outlining and analyzing measures that can be implemented in every country to promote and advance CKD prevention. Primary prevention of kidney disease should focus on the modification of risk factors and addressing structural abnormalities of the kidney and urinary tracts, as well as exposure to environmental risk factors and nephrotoxins. In persons with pre-existing kidney disease, secondary prevention, including blood pressure optimization and glycemic control, should be the main goal of education and clinical interventions. In patients with advanced CKD, the management of comorbidities such as uremia and cardiovascular disease is a highly recommended preventative intervention to avoid or delay dialysis or kidney transplantation. Political efforts are needed to proliferate the preventive approach. While national policies and strategies for non-communicable diseases might be present in a country, specific policies directed toward education and awareness about CKD screening, management, and treatment are often lacking. Hence, there is an urgent need to increase awareness of the importance of preventive measures throughout populations, professionals, and policy makers.

Validation and applicability of an alternative method for dialysis water and dialysate quality analysis / Validação e aplicabilidade de um método alternativo para análise da qualidade da água e do dialisato em diálise

ABSTRACT Introduction: In hemodialysis, patients are exposed to a large volume of water, which may lead to fatal risks if not meeting quality standards. This study aimed to validate an alternative method for monitoring microbiological quality of treated water and assess its applicability in dialysis and dialysate analysis, to allow corrective actions in real-time. Methods: Validation and applicability were analyzed by conventional and alternative methods. For validation, E. coli standard endotoxin was diluted with apyrogenic water in five concentrations. For the applicability analysis, treated water for dialysis was collected from different points in the treatment system (reverse osmosis, drainage canalization at the storage tank bottom, reuse, and loop), and dialysate was collected from four machines located in different rooms in the hemodialysis sector. Results: The validation results were in accordance with the Brazilian Pharmacopoeia acceptance criteria, except for the last two concentrations analyzed. In addition, the ruggedness criterion performed under the US Pharmacopoeia was in agreement with the results. Discussion: A limiting factor in the applicability analysis was the absence of the endotoxin maximum permitted level in dialysate by the Brazilian legislation. When comparing the analysis time, the alternative method was more time-consuming than the conventional one. This suggests that the alternative method is effective in the case of few analyses, that is, real-time analyses, favoring corrective actions promptly. On the other hand, it does not support the implementation of the alternative method in a laboratory routine due to the high demand for analyses.

RESUMO Introdução: Na hemodiálise, os pacientes são expostos a um grande volume de água, o que pode levar a riscos fatais se não cumprir com padrões de qualidade. Este estudo teve como objetivo validar um método alternativo para monitorar a qualidade microbiológica da água tratada e avaliar sua aplicabilidade em análises de diálise e dialisato, para permitir ações corretivas em tempo real. Métodos: A validação e aplicabilidade foram analisadas por métodos convencionais e alternativos. Para validação, a endotoxina padrão de E. coli foi diluída com água apirogênica em cinco concentrações. Para a análise de aplicabilidade, a água tratada para diálise foi coletada em diferentes pontos do sistema de tratamento (osmose reversa, canalização de drenagem no fundo do tanque de armazenamento, reutilização e circuito) e o dialisato foi coletado em quatro máquinas localizadas em diferentes salas do setor de hemodiálise. Resultados: Os resultados da validação obedeceram aos critérios de aceitação da Farmacopeia Brasileira, com exceção das duas últimas concentrações analisadas. Além disso, o critério de robustez realizado sob a Farmacopeia dos EUA estava de acordo com os resultados. Discussão: Um fator limitante na análise de aplicabilidade foi a ausência do nível máximo permitido de endotoxina no dialisato pela legislação brasileira. Ao comparar o tempo de análise, o método alternativo consumiu mais tempo que o convencional. Isso sugere que o método alternativo é eficaz no caso de poucas análises, ou seja, análises em tempo real, favorecendo ações corretivas imediatamente. Por outro lado, não suporta a implementação do método alternativo em uma rotina de laboratório devido à alta demanda por análises.

Analysis of hemodialysis water quality from 2008 to 2016 in Minas Gerais, Brazil / Análise da qualidade da água de hemodiálise durante o período de 2008 a 2016 em Minas Gerais, Brasil

Water quality requirements for hemodialysis are crucial for preventing health risks for renal patients. The objective of this study was to assess the quality of the water used for hemodialysis treatments in the state of Minas Gerais. The analytical results for 25 parameters in 1056 hemodialysis water samples from 89 renal dialysis units were analyzed. Data were obtained through the Minas Gerais Hemodialysis Unit Quality Monitoring Programme between July 2008 and December 2016. The effects of the Programme on patient health protection were assessed by evaluating compliance with legal limits and the efficacy of implementing inspections from 2012. Considering the 1056 samples analyzed, 264 (25%) presented at least one parameter in disagreement with current legislation. Conductivity (9.8%), endotoxin (6.9%), fluoride (4.2%) and heterotrophic bacteria (2.2%) were the most critical parameters. Nevertheless, the concentrations of all these parameters (except fluoride) decreased after implementing inspections. The average levels of 15 parameters decreased throughout the study period. The annual percentage of non-compliance decreased from 44% in 2008 to 23% in 2016. It was verified the relevance of the implementation of the Program in the prevention of possible disorders to the patients’ health, indicating the importance of its continuity.

Os requisitos de qualidade da água para a hemodiálise são cruciais para prevenir riscos à saúde de pacientes renais. O objetivo foi avaliar a qualidade da água utilizada nos tratamentos de hemodiálise em Minas Gerais. Os dados foram obtidos por meio do Programa de Monitoramento da Qualidade dos Serviços de Hemodiálise do Estado entre julho de 2008 e dezembro de 2016. Os resultados analíticos para 25 parâmetros em 1056 amostras de água em hemodiálise de 89 unidades renais foram analisados. Os efeitos do Programa na saúde dos pacientes foram avaliados através da conformidade dos limites legais e da eficácia da implementação de inspeções a partir de 2012. Considerando-se as 1056 amostras analisadas, 264 (25%) apresentaram pelo menos um parâmetro em desacordo com a legislação vigente. Condutividade, endotoxina, fluoreto e bactérias heterotróficas foram os parâmetros mais críticos. No entanto, as concentrações de todos esses parâmetros (exceto flúor) diminuíram após a implementação das inspeções. Os níveis médios de 15 parâmetros diminuíram ao longo do período do estudo. O percentual anual de não conformidade diminuiu de 44% (2008) para 23% (2016). Verificou-se a relevância da implantação do Programa na prevenção de possíveis transtornos à saúde dos pacientes, indicando a importância de sua continuidade.

Quality assessment of vascular access procedures for hemodialysis: A position paper of the Vascular Access Society based on the analysis of existing guidelines.

Quality assessment in vascular access procedures for hemodialysis is not clearly defined. The aim of this article is to compare various guidelines regarding recommendation on quality control in angioaccess surgery. The overall population of end-stage renal disease patients and patients in need for hemodialysis treatment is growing every year. Chronic intermittent hemodialysis is still the main therapy. The formation of a functional angioaccess is the cornerstone in the management of those patients. Native (autologous) arteriovenous fistula is the best vascular access available. A relatively high percentage of primary failure and fistula abandonment increases the need for quality control in this field of surgery. There are very few recommendations of quality assessment on creation of a vascular access for hemodialysis in the searched guidelines. Some guidelines recommend the proportion of native arteriovenous fistula in incident and prevalent patients as well as the maximum tolerable percentage of central venous catheters and complications. According to some guidelines, surgeon's experience and expertise have a considerable influence on outcomes. There are no specific recommendations regarding surgeon's specialty, grade, level of skills, and experience. In conclusion, there is a weak recommendation in the guidelines on quality control in vascular access surgery. Quality assessment criteria should be defined in this field of surgery. According to these criteria, patients and nephrologists could choose the best vascular access center or surgeon. Centers with best results should be referral centers, and centers with poorer results should implement quality improvement programs.

Is Preoperative Preparation Time a Barrier to Small Children Being Ready for Kidney Transplantation?

BACKGROUND: Small children are less frequently transplanted when compared with older. The objective of the present study was to compare the preparation time for transplantation in children of different weights and to identify factors associated with a delay in the workup of small children. METHODS: We report on a retrospective cohort comprising all children referred for renal transplantation (RTx) workup between 2009 and 2017. The main outcome was transplantation workup time, defined as the time elapsed between the first consultation and when the child became ready for the surgery. RESULTS: A total of 389 children (63.5% males) were selected, with a median weight of 18 kg (interquartile range, 11-32). Patients were categorized into 2 groups: group A (study group): ≤15 kg (n = 165) and group B (control group): >15 kg (n = 224). The probability of being ready for RTx was comparable between groups A and B. The cumulative incidence rate difference between groups is -0.05 (95% confidence interval, -0.03 to 0.02). The median time for RTx workup was 5.4 (2.4-9.4) in group A and 4.3 (2.2-9.0) months in group B (P = 0.451). Moreover, the presence of urinary tract malformation was associated with the need for longer transplantation workup time (P < 0.001). CONCLUSIONS: In children >7 kg, the workup time for transplantation is not related to body weight. In a specialized center, children weighing 7-15 kg became ready within the same timeframe as children weighing >15 kg, despite the smaller children had greater difficulty being nourished, dialyzed, and a greater need for surgical correction of the urinary tract pretransplant.

ASDIN white paper: Assessment and management of hemodialysis access-induced distal ischemia by interventional nephrologists.

Although not common, hemodialysis access-induced distal ischemia is a serious condition resulting in significant hemodialysis patient morbidity. Patients with signs and symptoms suggestive of hand ischemia frequently present to the general and interventional nephrologist for evaluation. In order to care for these cases, it is necessary to understand this syndrome and its management. Most cases can be managed conservatively without intervention. Some cases requiring intervention may be treated using techniques within the scope of practice of the interventional nephrologists while other cases require vascular surgery. In order for the interventional nephrologists to evaluate and manage these cases in a timely and appropriate manner, practice guidelines are presented.

Fluid and hemodynamic management in hemodialysis patients: challenges and opportunities / Manejo hídrico e hemodinâmico em pacientes em hemodiálise: desafios e oportunidades

Abstract Fluid volume and hemodynamic management in hemodialysis patients is an essential component of dialysis adequacy. Restoring salt and water homeostasis in hemodialysis patients has been a permanent quest by nephrologists summarized by the 'dry weight' probing approach. Although this clinical approach has been associated with benefits on cardiovascular outcome, it is now challenged by recent studies showing that intensity or aggressiveness to remove fluid during intermittent dialysis is associated with cardiovascular stress and potential organ damage. A more precise approach is required to improve cardiovascular outcome in this high-risk population. Fluid status assessment and monitoring rely on four components: clinical assessment, non-invasive instrumental tools (e.g., US, bioimpedance, blood volume monitoring), cardiac biomarkers (e.g. natriuretic peptides), and algorithm and sodium modeling to estimate mass transfer. Optimal management of fluid and sodium imbalance in dialysis patients consist in adjusting salt and fluid removal by dialysis (ultrafiltration, dialysate sodium) and by restricting salt intake and fluid gain between dialysis sessions. Modern technology using biosensors and feedback control tools embarked on dialysis machine, with sophisticated analytics will provide direct handling of sodium and water in a more precise and personalized way. It is envisaged in the near future that these tools will support physician decision making with high potential of improving cardiovascular outcome.

Resumo O volume de fluidos e o controle hemodinâmico em pacientes em hemodiálise é um componente essencial da adequação da diálise. A restauração da homeostase do sal e da água em pacientes em hemodiálise tem sido uma busca constante por parte dos nefrologistas, no que condiz à abordagem do "peso seco. Embora essa abordagem clínica tenha sido associada a benefícios no desfecho cardiovascular, recentemente tem sido questionada por estudos que mostram que a intensidade ou agressividade para remover fluidos durante a diálise intermitente está associada a estresse cardiovascular e dano potencial a órgãos.para remover fluidos durante a diálise intermitente está associada a estresse cardiovascular e dano potencial a órgãos. Uma abordagem mais precisa é necessária para melhorar o desfecho cardiovascular nessa população de alto risco. A avaliação e monitorização do estado hídrico baseiam-se em quatro componentes: avaliação clínica, ferramentas instrumentais não invasivas (por exemplo, US, bioimpedância, monitorização do volume sanguíneo), biomarcadores cardíacos (e.g. peptídeos natriuréticos), algoritmos e modelagem de sódio para estimar a transferência de massa. O manejo otimizado do desequilíbrio hídrico e de sódio em pacientes dialíticos consiste em ajustar a remoção de sal e líquido por diálise (ultrafiltração, dialisato de sódio), e restringir a ingestão de sal e o ganho de líquido entre as sessões de diálise. Tecnologia moderna que utiliza biosensores e ferramentas de controle de feedback, hoje parte da máquina de diálise, com análises sofisticadas, proporcionam o manejo direto sobre o sódio e a água de uma maneira mais precisa e personalizada. Prevê-se no futuro próximo que essas ferramentas poderão auxiliar na tomada de decisão do médico, com alto potencial para melhorar o resultado cardiovascular.

Clinical practice guideline management of blood borne viruses within the haemodialysis unit.

Some people who are receiving dialysis treatment have virus infection such as hepatitis B, hepatitis C and/or HIV that is present in their blood. These infections can be transmitted to other patients if blood is contaminated by the blood of another with a viral infection. Haemodialysis is performed by passing blood from a patient through a dialysis machine, and multiple patients receive dialysis within a dialysis unit. Therefore, there is a risk that these viruses may be transmitted around the dialysis session. This documents sets out recommendations for minimising this risk.There are sections describing how machines and equipment should be cleaned between patients. There are also recommendations for dialysing patients with hepatitis B away from patients who do not have hepatitis B. Patients should be immunised against hepatitis B, ideally before starting dialysis if this is possible. There are guidelines on how and when to do this, for checking whether immunisation is effective, and for administering booster doses of vaccine. Finally there is a section on the measures that should be taken if a patient receiving dialysis is identified as having a new infection of hepatitis B, hepatitis C or HIV.

Comparison of Solute Clearance, Hospitalization Rate, and Aortic Arch Calcification between Online Hemodiafiltration and High-Flux Hemodialysis: A 6-Year Observational Study.

BACKGROUND/AIMS: Studies on the long-term clinical benefits of hemodiafiltration (HDF) and high-flux hemodialysis (HFHD) are very limited. This study aimed to investigate the hospitalization rate and aortic arch calcification (AAC) of these two dialysis modalities over 6 years. METHODS: Participants who received regular HDF and HFHD in one hospital-facilitated hemodialysis center were prospectively enrolled after matching for age, sex, and diabetes between January 2009 and December 2014. Medical records were reviewed retrospectively on demographics, laboratory variables, calcified scores in aortic arch measured by chest radiography, and rates of hospital admission. Cox proportional hazard regression and linear regression were used to obtain the outcome results. RESULTS: The HDF and HFHD groups consisted of 108 and 102 participants, respectively. Levels of laboratory variables including small soluble solutes and Kt/V were not statistically different over the 6-year period between the HDF and HFHD groups. Calcified scores of the aortic arch increased over 6 years in both groups. The changes in the mean calcified scores were significant when compared between the two groups (0.44-1.82 in HFHD, 0.79-1.8 in HDF, respectively, p = 0.008). Hospitalization rates were 735 per 1,000 patients in the HDF group and 852 per 1,000 patients in the HFHD group, respectively. No significant difference was observed in frequency and days of hospitalization between HDF and HFHD. CONCLUSION: Hospitalization rates and AAC were observed to be equal for HDF and HFHD.

Two-Year Outcomes of Early Cannulation Arteriovenous Grafts for End-Stage Renal Disease.

BACKGROUND: Almost 80% of patients with end-stage renal disease (ESRD) initiate dialysis via a central venous catheter (CVC). CVCs are associated with multiple complications and a high cost of care. The purpose of our project is to determine the impact of early cannulation arteriovenous grafts (ECAVGs) on quality of care and costs. METHODS: The dialysis access modality, complications, secondary interventions, hospital outcomes, and detailed costs were tracked for 397 sequential patients who underwent access creation between July 2014 and October 2018. Complications were grouped into deep vein thrombosis, line infections, sepsis, pneumothorax, and other. Secondary interventions included angioplasty, angioplasty and stent grafting, thrombectomy, surgical revision, and explantation. Hospital outcomes included length of stay, inpatient mortality, 30-day readmission, and discharge disposition. Costs included supplies, medications, laboratory tests, labor, and other direct costs. All variables were measured at the time of the index procedure, 30 days, 90 days, 180 days, 270 days, 1 year, 18 months, and 2 years. RESULTS: There were 131 patients who underwent arteriovenous fistula (AVF) and 266 who received ECAVG for dialysis access. The total cost of care per patient was $17,523 for AVF and $5,894 for ECAVG at 1 year (P < 0.01). Primary-assisted patency for AVF was 49.3% versus 81.4% for ECAVG (P = 0.027), and secondary-assisted patency for AVF was 63.8% versus 85.4% for ECAVG at 1 year (P = 0.011). There was a survival advantage for ECAVGs at 1 year (78.6% for AVF vs 85.0% for ECAVG, P = 0.034). Patients who received ECAVG had fewer CVC days (2.3% vs 19.1% for AVF, P < 0.001), fewer complications (1.6% vs. 21.5% for AVF, P < 0.001), and fewer secondary interventions (17.0% vs 52.5% for AVF, P < 0.001). CONCLUSIONS: This is the first study on patients with ESRD to report detailed outcomes and cost analysis as it relates to AVF versus ECAVG. ECAVGs have an advantage over AVFs due to lower overall cost and better clinical outcomes at 1 year. Implementation of an urgent start dialysis access program centered around ECAVGs may help achieve the national goal of better health care at a lower cost for patients with ESRD.

Translation and cultural adaptation of Patient Perceptions of Hemodialysis Scale in Brazil / La traducción y adaptación cultural de Patient Perceptions of Hemodialysis Scale al portugués de Brasil / Tradução e adaptação cultural da Patient Perceptions of Hemodialysis Scale no Brasil

ABSTRACT Objective: To translate and adapt the Patient Perceptions of Hemodialysis Scale (PPHS) to the Brazilian context. Method: A methodological study, in which the stages of initial translation, synthesis of translations, back translation, evaluation by an expert committee and pre-test of the PPHS were performed. Results: Two initial translations by independent translators, experienced in the health area and fluent in English. Subsequently, the synthesis of the translations was carried out, and this synthesis was back translated to the original language (American English).The translated and back-translated versions were evaluated by an expert committee made up of six PhD experts from the health area. The judges' evaluations resulted in content validity indexes for each item of the scale, and 7 of the 36 items had to be revised. Subsequently, a pretest was carried out with 20 participants, who considered the instrument intelligible. Conclusion: The PPHS is adequately translated and adapted to Brazilian Portuguese.

Refractory ascites and graft dysfunction in early renal transplantation.

The occurrence of ascites after Renal Transplant (RT) is infrequent, and may be a consequence of surgical or medical complications. Case report: 61 year-old, male, history of arterial hypertension, tongue carcinoma and alcoholic habits 12-20g/day. He had chronic kidney disease secondary to autosomal dominant polycystic kidney disease, without hepatic polycystic disease. He underwent cadaver donor RT in September 2017. He had delayed graft function by surgically corrected renal artery stenosis. He was admitted in January 2018 for ascites de novo, with no response to diuretics. HE had visible abdominal collateral circulation. Graft dysfunction, adequate tacrolinemia, Innocent urinary sediment, mild anemia, without thrombocytopenia. Serum albumin 4.0g / dL. Normal hepatic biochemistry. Peritoneal fluid with transudate characteristics and serum albumin gradient > 1.1. Ultrasound showed hepatomegaly, permeable vascular axes, without splenomegaly. Mycophenolate mofetil was suspended, with reduced remaining immunosuppression. He maintained refractory ascites: excluded infectious, metabolic, autoimmune and neoplastic etiologies. No nephrotic proteinuria and no heart failure. MRI: micronodules compatible with bile cysts. Upper Digestive Tract Endoscopy did not show gastroesophageal varicose veins. Normal abdominal lymphoscintigraphy. He underwent exploratory laparoscopy with liver biopsy: incomplete septal cirrhosis of probable vascular etiology some dilated bile ducts. He maintained progressive RT dysfunction and restarted hemodialysis. The proposed direct measurement of portal pressure was delayed by ascites resolution. There was further recovery of the graft function. Discussion: Incomplete septal cirrhosis is an uncommon cause of non-cirrhotic portal hypertension. Its definition is not well known, morphological and pathophysiological. We have not found published cases of post-RT ascites secondary to this pathology, described as possibly associated with drugs, immune alterations, infections, hypercoagulability and genetic predisposition.

Misplacement of Tunneled Hemodialysis Catheter into Azygos Vein: Left or Right Jugular Insertion Has Similar Susceptibility.

BACKGROUND: Central venous catheter (CVC) is commonly used to provide access for hemodialysis (HD) when arteriovenous access is not available. The misplacement of CVC into azygos vein (AV) is a rare but a potential serious complication. Previous reports communicated the opinion that left-sided catheterization predisposed to AV misplacement, but these reports concentrated on peripherally inserted CVCs, placed for indications rather than HD. Unintended AV misplacement of HD catheters (HDCs) has not been well studied. We seek to investigate factors associated with inadvertent AV miscannulation during HDC placement. METHODS: We are to present a case of unintentional misplacement of a tunneled HD catheter (tHDC) into the azygos arch from right internal jugular vein (RIJV) despite real-time fluoroscopy guidance. Additionally, we have undertaken a systematic literature search in Pubmed to study the anatomical and other factors related to unintended AV misposition in HD setting. RESULTS: From 2005 to August 31, 2018, a total of 11 articles containing 16 cases of misplacement of HDCs into AV were identified. Of the 17 cases of unintentional AV misposition including ours, the majority of the misguided HDCs (94.1%, 16/17) were tHDCs and only 1 case was related to a temporary (non-tunneled) catheter. Most catheter misplacements (88.2%, 15/17) were performed without real-time radiological guidance. The reported incidence of inadvertent AV cannulation from different institutions varied between 0.6% and 3.8%. Among the 16 misplaced tHDCs, the rates of AV misposition that arose from RIJV and left internal jugular vein (LIJV) insertion are even at 50%. CONCLUSIONS: Based upon anatomical and case studies, we have found that AV may join posterior aspect of superior vena cava at different directions and levels. Hence, this might explain why AV misplacement might occur whether an HDC is inserted from the LIJV or RIJV approach. By raising the awareness of this potential complication and how we may minimize it, we hope to reduce the future complication of AV misposition.
